Child abuse is often an ongoing process. If the diagnosis is missed, children may go on to be more seriously abused, which can prove fatal. Although there is no uniformly applicable screening protocol for child abuse, screening has shown to be useful in supporting the identification of children at high risk for abuse.[57]Louwers EC, Affourtit MJ, Moll HA, et al. Screening for child abuse at emergency departments: a systematic review. Arch Dis Child. 1977 Jun;9(6):579-86.

A detailed history, followed by a meticulous examination, is critical in making the diagnosis of physical child abuse. The range of injuries caused by physical abuse include bruising, fractures, oral injuries, bites, head and spinal injuries, abdominal injuries, and burns. The challenge for the clinician is to distinguish inflicted injuries from those that have occurred accidentally. Finding one or more of the above injuries in a child should warrant a full further evaluation to look for other injuries typical of abuse.[10]Christian CW, Committee on Child Abuse and Neglect, American Academy of Pediatrics. The evaluation of suspected child physical abuse. Pediatrics. 2015 May;135(5):e1337-54.

http://www.ncbi.nlm.nih.gov/pubmed/25917988?tool=bestpractice.com
Many children who have suffered some form of abuse present to the accident and emergency department or clinic; however, none of the screening markers currently used to identify children who should be assessed further for possible abuse or neglect (e.g., repeated presentation, age, injury type) have been found to be sufficiently accurate. Therefore, clinicians should maintain a high level of suspicion for abuse in injured children who present to the A&E department or clinic with or without these specific characteristics of abuse.[59]Woodman J, Lecky F, Hodes D, et al. Screening injured children for physical abuse or neglect in emergency departments: a systematic review. Child Care Health Dev. 2010 Mar;36(2):153-64.
http://www.ncbi.nlm.nih.gov/pubmed/20047596?tool=bestpractice.com
Clinical prediction rules are being developed to assist professionals in identifying children that would most benefit from an abuse work up as well as reduce the variability in practice of which a child is affected by an abuse work up. One such clinical prediction rule, the TEN-4 rule, is highly specific and sensitive for identifying high-risk bruising that requires an abuse work up in a paediatric intensive care population.[60]Pierce MC, Kaczor K, Aldridge S, et al. Bruising characteristics discriminating physical child abuse from accidental trauma. Pediatrics. 2010 Jan;125(1):67-74.
http://www.ncbi.nlm.nih.gov/pubmed/19969620?tool=bestpractice.com
A bruise on a child’s torso, ears, neck, or any part of the body of an infant <4 months old (TEN-4) should trigger an abuse evaluation. Two clinical prediction rules for abusive head trauma have been validated with impressive specificity and/or sensitivity for detecting abusive head trauma.[61]Hymel KP, Armijo-Garcia V, Foster R, et al. Validation of a clinical prediction rule for pediatric abusive head trauma. Pediatrics. 2014 Dec;134(6):e1537-44.

History suggestive of non-accidental injury (NAI)
Determining whether injuries have been caused accidentally or represent abuse may be challenging. A detailed history should include explanations for the injury present. The following considerations may be helpful in making the diagnosis of NAI:
A history of trauma inconsistent with the injuries, a changing or inconsistent history, other unexplained co-existent injuries, or previous history of injuries.[2]Suniega EA, Krenek L, Stewart G. Child abuse: approach and management. Am Fam Physician. 2022 May 1;105(5):521-8.
http://www.ncbi.nlm.nih.gov/pubmed/35559624?tool=bestpractice.com
Injuries that do not fit with the developmental age of the child (e.g., if children are not yet independently mobile, they may be unlikely to fall against certain objects).[63]Sugar NF, Taylor JA, Feldman KW. Bruises in infants and toddlers; those who don't cruise rarely bruise. Puget Sound Pediatric Research Network. Arch Paediatr Adolesc Med. 1999 Apr;153(4):399-403.
https://jamanetwork.com/journals/jamapediatrics/fullarticle/346535
http://www.ncbi.nlm.nih.gov/pubmed/10201724?tool=bestpractice.com
Details of the proposed mechanism of injury may help to determine whether the explanation is compatible with the injury and the developmental level of the child.
Children known to social services, particularly if parental/carer risk factors are also present.
Faltering growth or failure to thrive.[2]Suniega EA, Krenek L, Stewart G. Child abuse: approach and management. Am Fam Physician. 2022 May 1;105(5):521-8.
http://www.ncbi.nlm.nih.gov/pubmed/35559624?tool=bestpractice.com

http://www.ncbi.nlm.nih.gov/pubmed/16264015?tool=bestpractice.com
Poor parent-child bonding.
Parental attempts at excusing or justifying the injury inappropriately or blaming a younger sibling or pet.
To exclude non-abusive causes, the clinician should ask questions about the perinatal history (including birth-related trauma), any history of prematurity, physiotherapy and other possible iatrogenic causes, and medicines. Past medical history of fractures or bleeding disorders is important. Questions about family history of fractures, blue sclera, and deafness can help to exclude osteogenesis imperfecta.[64]Bishop N, Sprigg A, Dalton A. Unexplained fractures in infancy: looking for fragile bones. Arch Dis Child. 2007 Mar;92(3):251-6.
http://www.ncbi.nlm.nih.gov/pubmed/17337685?tool=bestpractice.com
Other family history, such as that of clotting disorders or metabolic disease, is also important.
It is vital to ascertain all relevant information about the child's family and/or carers, including previous attendance in primary or secondary care, any previous registration with social services, and relevant information on other adults and children in the home. Any history of drug dependency or previous convictions should be noted.
Head injuries
Brain injury is one of the most severe consequences of physical abuse. Abusive head trauma (AHT) is the most common cause of fatal physical abuse, with mortality ranging from 11% to 38%.[24]Vinchon M, Defoort-Dhellemmes S, Desurmont M, et al.

Some children die before they reach hospital, and the first presentation is to the pathologist.
AHT and related injuries can result from various biomechanical forces, including shaking alone, shaking with impact, or impact alone.[15]Centers for Disease Control and Prevention. Child abuse and neglect prevention. Apr 2022 [internet publication].

Presenting features range from severe neurological compromise (coma) to symptoms such as seizures, lethargy, irritability, vomiting, poor feeding, and increasing head circumference. Identifying the abused child who presents with such non-specific symptoms is particularly challenging, resulting in missed cases.[71]Jenny C, Hymel KP, Ritzen A, et al. Analysis of missed cases of abusive head trauma. JAMA. 1999 Feb 17;281(7):621-6.
http://www.ncbi.nlm.nih.gov/pubmed/10029123?tool=bestpractice.com

Skull fractures are prevalent in accidental injury and abuse. The most common type of fracture in both situations is a linear parietal fracture.
Retinal haemorrhages in multiple retinal layers and extending to the periphery is highly specific for AHT, and it is seen in up to 85% of cases.[22]Hobbs C, Childs AM, Wynne J, et al. Subdural haematoma and effusion in infancy: an epidemiological study. Arch Dis Child. 2005 Sep;90(9):952-5.

Retinal haemorrhages have also been recorded following accidental high-impact trauma, which should be evident on history. Infants <6 weeks of age may have minor retinal haemorrhages following birth, particularly after a ventouse or other instrumental delivery.[77]Hughes LA, May K, Talbot JF, et al.

However, retinal haemorrhages associated with these medical causes have distinctly different characteristics than those seen in inflicted and significant trauma.[78]Maguire SA, Watts PO, Shaw AD, et al.

http://www.ncbi.nlm.nih.gov/pubmed/23079748?tool=bestpractice.com
Subdural haemorrhages are the most common intracranial injury seen in AHT, and may occur in combination with other extra-axial haemorrhages or injuries to the brain itself. Physical abuse is the most common cause of subdural haemorrhage in children <1 year of age.[20]Keenan HT, Runyan DK, Marshall SW, et al.

Spinal injuries
Although spinal injuries are uncommon in children with physical abuse, the consequences can be devastating.[82]Gabos PG, Tuten HR, Leet A, et al. Fracture-dislocation of the lumbar spine in an abused child. Pediatrics. 1998 Mar;101(3 Pt 1):473-7.

They should be considered in any young child with severe abusive injuries (e.g., AHT). The true prevalence of spinal injury with AHT is difficult to estimate as spinal symptoms are often masked by loss of consciousness. Unstable spinal fractures such as hangman's fracture may occur as a consequence of abuse and constitute a neurosurgical emergency.[84]Oral R, Rahhal R, Elshershari H, et al. Intentional avulsion fracture of the second cervical vertebra in a hypotonic child. Pediatr Emerg Care. 2006 May;22(5):352-4.

Spinal lesions may occur in the cervical spine, commonly in association with abusive head injury in younger infants (mean age 5 months) or in the thoraco-lumbar spine in older toddlers (mean age 14 months).[86]Kemp AM, Joshi AH, Mann M, et al. What are the clinical and radiological characteristics of spinal injuries from physical abuse: a systematic review. Arch Dis Child. 2010 May;95(5):355-60.
http://www.ncbi.nlm.nih.gov/pubmed/19946011?tool=bestpractice.com
Children may present with bony tenderness over the site of the vertebral fracture or with specific neurological signs referable to the spinal tract, such as paraplegia, quadriplegia, incontinence, or absent sensation below the level of cord injury. Unexplained kyphosis in an older child should also raise a suspicion of previous abuse.[87]Cullen JC. Spinal lesions in battered babies. J Bone Joint Surg (Br). 1975 Aug;57(3):364-6.
http://www.ncbi.nlm.nih.gov/pubmed/1158948?tool=bestpractice.com
Abdominal injuries
Although abdominal injuries appear to be rare, they carry a high mortality and morbidity.[88]Barnes PM, Norton CM, Dunstan FD, et al. Abdominal injury due to child abuse. Lancet. 2005 Jul 16-22;366(9481):234-5.
http://www.ncbi.nlm.nih.gov/pubmed/16023514?tool=bestpractice.com
They are predominantly seen in children <5 years of age. Children with abusive abdominal trauma often present with no specific history of trauma to the abdomen and may present with non-specific symptoms such as nausea, vomiting, loss of consciousness, and/or an acute abdomen. Frequently, there is a delay in seeking care. Abdominal injuries may occasionally be masked by symptoms and signs of head injury. The most specific blunt injuries to the abdomen as a consequence of abuse are hollow viscus injuries, which are often associated with other abdominal injuries (e.g., small bowel and hepatic injury) or with bruising, fractures, torn frenum, head injury, bites, and burns. Solid organ injuries are common in both inflicted and accidental abdominal trauma.[28]Wood J, Rubin DM, Nance ML, et al. Distinguishing inflicted versus accidental abdominal injuries in young children. J Trauma. 2005 Nov;59(5):1203-8.
http://www.ncbi.nlm.nih.gov/pubmed/16385300?tool=bestpractice.com
Bruising over the abdomen is seen in ony a minority of cases.
Accidental abdominal injuries usually follow motor vehicle accidents or significant falls and are often associated with solid organ injuries.[89]Wegner S, Colletti JE, Van Wie D. Pediatric blunt abdominal trauma. Pediatr Clin North Am. 2006 Apr;53(2):243-56.

Fractures
Up to one third of children <2 years of age who have experienced physical child abuse sustain fractures.[90]Belfer RA, Klein BL, Orr L. Use of the skeletal survey in the evaluation of child maltreatment. Am J Emerg Med. 2001 Mar;19(2):122-4

These are frequently occult and not suspected clinically. Abusive fractures occur predominantly in babies and toddlers; fractures sustained after accidents, in contrast, are more frequent in school-age children.[93]Worlock P, Stower M, Barbor P.

Any long-bone fracture in a pre-mobile child should have a clear accidental explanation, and if not, abuse should be actively excluded.
Abusive fractures have been recorded in every bone or group of bones in the body.
Rib fractures are the strongest predictors of child abuse in infants in the absence of major trauma or pathological causes, and are due to either the squeezing of the chest or a direct blow.[29]Bulloch B, Schubert CJ, Brophy PD, et al. Cause and clinical characteristics of rib fractures in infants. Pediatrics. 2000 Apr;105(4):E48.

Fractures of long bones with an adequate history for injury in ambulatory children are more commonly accidental.
Classic metaphyseal lesions (also called metaphyseal fractures, corner fractures, or bucket handle fractures) are highly specific for abuse in infants under 1 year of age.[97]Kleinman PK. Diagnostic imaging of child abuse. Maryland Heights, MO: Mosby; 1998. These fractures occur from shearing strain across the metaphysis from vigorous flailing, pulling, or twisting of an extremity.[98]Kleinman PK. Problems in the diagnosis of metaphyseal fractures.

Oral injuries
Distinguishing accidental from non-accidental oral injuries may be difficult. The mouth should be fully examined, and any missing or abnormal teeth recorded. It is also very important to be aware of normal dentition in a child and to be alert to subtle changes (e.g., changes to coloration of teeth). The most common oral injuries described are bruising or lacerations to the lips.[104]Naidoo S. A profile of the oro-facial injuries in child physical abuse at a children's hospital. Child Abuse Negl. 2000 Apr;24(4):521-34.

Other possible oral injuries include:
Torn frenum (or frenulum)
When found, it is frequently associated with severe or fatal injuries (usually head injury).[32]Thackeray JD. Frena tears and abusive head injury: a cautionary tale. Pediatr Emerg Care. 2007 Oct;23(10):735-7.

http://www.ncbi.nlm.nih.gov/pubmed/17468129?tool=bestpractice.com
Any unexplained bruising to the cheeks, ears, neck, or trunk in association with a torn frenum should raise concern for abuse, and a full child protection investigation is warranted. A torn frenum may occur by force-feeding an infant, although it has only conclusively been reported following a direct blow.[34]Maguire S, Hunter B, Hunter L, et al; Welsh Child Protection Systematic Review Group.

It is accompanied by a lot of apparent bleeding (mixed saliva and blood).
A torn frenum "in isolation" (i.e., having excluded any other occult injury such as fracture or head injury, and in absence of other risk factors) cannot always be assumed to be abusive. It may also occur accidentally, from a direct blow (e.g., swing hitting mouth, fall onto face, sporting injury). Torn frenum has been described during attempted intubation.[34]Maguire S, Hunter B, Hunter L, et al; Welsh Child Protection Systematic Review Group.

Dental injuries
If any dental injury is suspected, it is advisable to seek the opinion of a paediatric dentist. Abusive dental injuries include forced intrusions, extrusions, removal of healthy secondary teeth, and micro-fractures.[104]Naidoo S. A profile of the oro-facial injuries in child physical abuse at a children's hospital. Child Abuse Negl. 2000 Apr;24(4):521-34.

Parents have been known to forcefully extract a child's healthy teeth as a "punishment".[37]Carrotte PV. An unusual case of child abuse. Br Dental J. 1990 Jun 9;168(11):444-5.
http://www.ncbi.nlm.nih.gov/pubmed/2361086?tool=bestpractice.com
Some dental injuries may not be immediately obvious to the medical practitioner (e.g., grey discoloration of the teeth from a previous micro-fracture, or missing secondary dentition).
Failure to take a child to a dentist following previous dental injuries, rampant untreated caries, or gum disease may indicate dental neglect and should also raise suspicion of abuse. Parents may underestimate the extent of dental neglect, but these problems can cause considerable pain to the child. Dental neglect may also be a reflection of inappropriate dietary intake.
Up to 50% of children with dental injuries sustain them accidentally, commonly from falls or sports injuries.[107]Andreasen JO. Challenges in clinical dental traumatology. Endodont Dent Traumatol. 1985 Apr;1(2):45-55.
http://www.ncbi.nlm.nih.gov/pubmed/3861314?tool=bestpractice.com
Greyish discoloration of the teeth may also occur with dentinogenesis imperfecta, particularly when associated with osteogenesis imperfecta, a condition resulting in recurrent fractures.
Bruising
Bruising is one of the most common accidental injuries that children sustain during normal day-to-day activities. However, bruising is also the most common manifestation of physical abuse.[108]McMahon P, Grossman W, Gaffney M, et al. Soft-tissue injury as an indication of child abuse. J Bone Joint Surg Am. 1995 Aug;77(8):1179-83.

Accidental bruising
Typically occurs in independently mobile children on the front of the body and over bony prominences.[63]Sugar NF, Taylor JA, Feldman KW.

The bruises are predominantly on the legs and shins. Bruising is uncommon in areas such as the back, buttocks, forearm, cheeks or face, ears, abdomen or hip, upper arm, posterior leg, foot, or hand.[111]Dunstan FD, Guildea ZE, Kontos K, et al.

http://www.ncbi.nlm.nih.gov/pubmed/11970921?tool=bestpractice.com
Bruising to the hands is extremely rare in children <2 years of age, and if found a clear explanation for the injury should be sought.
Accidental bruises to the head are most commonly found over the forehead, nose, upper lip, or chin,[112]Chang LT, Tsai MC. Craniofacial injuries from slip, trip, and fall accidents of children. J Trauma. 2007 Jul;63(1):70-4.
http://www.ncbi.nlm.nih.gov/pubmed/17622871?tool=bestpractice.com
in contrast to abusive bruises, found on cheeks, ear, neck, or peri-orbital area.[111]Dunstan FD, Guildea ZE, Kontos K, et al. A scoring system for bruise patterns: a tool for identifying abuse. Arch Dis Child. 2002 May;86(5):330-3.

http://www.ncbi.nlm.nih.gov/pubmed/11970921?tool=bestpractice.com
Although accidental bruising increases with age, developmental stage is a more relevant parameter. Less than 1% of babies not yet crawling or independently mobile have bruising (usually relating to birth injury), as opposed to 17% of those cruising around the furniture. This increases to 52% of children walking unaided.[63]Sugar NF, Taylor JA, Feldman KW. Bruises in infants and toddlers; those who don't cruise rarely bruise. Puget Sound Pediatric Research Network.

Non-accidental bruising
In abused children, the head and face is the most common site of bruising, along with bruises on buttocks and over soft tissues.[111]Dunstan FD, Guildea ZE, Kontos K, et al. A scoring system for bruise patterns: a tool for identifying abuse. Arch Dis Child. 2002 May;86(5):330-3.

The TEN-4 rule is a highly specific and sensitive clinical prediction rule for identifying high-risk bruising. It requires an abuse work-up in a paediatric intensive care population.[60]Pierce MC, Kaczor K, Aldridge S, et al. Bruising characteristics discriminating physical child abuse from accidental trauma.

A bruise on a child’s torso, ears, neck, or any part of the body of an infant <4 months old (TEN-4) should trigger an abuse evaluation.
Abusive bruises often occur in clusters and may show a pattern of defensive injuries (e.g., bruising to outside of the forearm and thighs).[10]Christian CW, Committee on Child Abuse and Neglect, American Academy of Pediatrics. The evaluation of suspected child physical abuse. Pediatrics. 2015 May;135(5):e1337-54.

Abusive bruising may reflect a positive or negative patterned image of the object used (e.g., belt buckle, dog collar) or it may be interspersed with abrasions (e.g., in rope injury).
Abusive bruises tend to be larger and more numerous than those found on children who have not been abused. Petechiae in association with bruises are significantly associated with abuse.[116]Nayak K, Spencer N, Shenoy M, et al. How useful is the presence of petechiae in distinguishing non-accidental from accidental injury? Child Abuse Negl. 2006 May;30(5):549-55.

Bites
Bites to children may be seen with both accidental injuries (e.g., child-to-child bites among toddlers) and abusive injuries.[120]Baker MD, Moore SE. Human bites in children. A six-year experience. Am J Dis Child. 1987 Dec;141(12):1285-90.
http://www.ncbi.nlm.nih.gov/pubmed/3687869?tool=bestpractice.com
Any adult (or older adolescent) who bites a child sufficient to leave an imprint of their teeth has caused an abusive injury.
Abusive bites may occur in younger children on the arms, legs, back, shoulders, and buttocks.[121]Freeman AJ, Senn DR, Arendt DM. Seven hundred seventy eight bite marks: analysis by anatomic location, victim and biter demographics, type of crime, and legal disposition. J Forens Sci. 2005 Nov;50(6):1436-43.
http://www.ncbi.nlm.nih.gov/pubmed/16382842?tool=bestpractice.com
Adolescents who are the victims of sexual abuse may be bitten over the breasts and neck, as in adult attacks. Any oval or circular lesion with indentations that correspond to teeth marks should be considered as a potential bite mark.[122]American Board of Forensic Odontology. ID & bitemark guidelines: body identification information & guidelines. Feb 2017 [internet publication].
https://abfo.org/resources/id-bitemark-guidelines
Distinguishing child bites from adult bites is challenging. Any bite with an inter-canine distance of >3 cm is more likely to be from an adult; an inter-canine distance of <2.5 cm is more likely to be from a young child (deciduous teeth), although some adults with abnormal dentition may leave such a small imprint.[123]Levine LJ. Bite marks in child abuse. In: Sanger RG, Bross DC, eds. Clinical management of child abuse and neglect. Chicago, IL: Quintessence; 1984:53-9. However, adult dentition is reached at around 12 years so distinguishing adult perpetrators from older children can be difficult.
Children may bite themselves when forced to stifle a cry during abuse. An abused child may also bite the attacker; the bite mark could potentially be matched to their dentition.[121]Freeman AJ, Senn DR, Arendt DM. Seven hundred seventy eight bite marks: analysis by anatomic location, victim and biter demographics, type of crime, and legal disposition. J Forens Sci. 2005 Nov;50(6):1436-43.
http://www.ncbi.nlm.nih.gov/pubmed/16382842?tool=bestpractice.com
Children are sometimes bitten by animals: most commonly dogs, cats, and ferrets. Animal bites are usually tearing injuries. If the lesion has puncture wounds (from canine teeth) with tearing injuries rather than compression of the flesh, it is more likely to be from a carnivorous animal.[124]Whittaker DK, MacDonald DG. Bitemarks in flesh. In: A colour atlas of forensic dentistry. London, UK: Wolfe Medical Publications; 1989:108.
Poisonings
Poisoning can be associated with fabricated or induced illness. Intentional poisoning is suspected when large quantities of a substance have been ingested, if the child is intoxicated, or if there is no history or a history of ingestion of small amounts of poison inconsistent with the clinical presentation. The most common agents of intentional poisoning include drugs prescribed for family members (e.g., anticonvulsants, antidepressants, iron, laxatives, or insulin) as well as salt, emetics, and illegal recreational drugs.[125]Yin S. Malicious use of pharmaceuticals in children. J Pediatr. 2010 Nov;157(5):832-6.e1
http://www.ncbi.nlm.nih.gov/pubmed/20650468?tool=bestpractice.com
Accidental poisoning is characterised by ingestion of small amounts of domestic products or medicines. The child is presented promptly by the parents or carers, who are able to give a history of ingestion or of the child being found in the proximity of an opened container of poison.
Frequent presentations with purported "accidental" ingestion should raise the suspicion of child neglect due to poor supervision or lack of safety provision in the home.
Burns
Scalds
The most common burns in childhood, both abusive and accidental, are scalds. It takes only a second for a young child to sustain a full-thickness scald from a liquid at 60°C (140°F).[126]Dressler DP, Hozid JL. Thermal injury and child abuse: the medical evidence dilemma.

Accidental scalds are typically the result of a "spill over" event (e.g., the child reaches up and pulls over a cup or pan of hot liquid).[126]Dressler DP, Hozid JL. Thermal injury and child abuse: the medical evidence dilemma. J Burn Care Rehabil. 2001 Mar-Apr;22(2):180-5.

http://www.ncbi.nlm.nih.gov/pubmed/15123901?tool=bestpractice.com
The history is key in differentiating accidental from abusive scalds, and it is important to understand the ages at which a child is able to perform certain actions (e.g., climb into a bath unattended).[131]Allasio D, Fischer H. Immersion scald burns and the ability of young children to climb into a bathtub. Pediatrics. 1990 Mar;6(1):58-61.
http://www.ncbi.nlm.nih.gov/pubmed/15867058?tool=bestpractice.com
Unusual accidents do occur and although a particular pattern of injury may seem unlikely, it may be explained by what the child was doing at that time (e.g., if the child was in a "walker", pooling of the liquid may lead to extensive injuries).[132]Johnson CF, Ericson AK, Caniano D. Walker-related burns in infants and toddlers. Pediatr Emerg Care. 1990 Mar;6(1):58-61.
http://www.ncbi.nlm.nih.gov/pubmed/2320488?tool=bestpractice.com
Accidental immersion scalds may also rarely occur. Typically, an accidental scald has the following characteristics:
Distribution: accidental scalds usually involve the face, head, neck, upper trunk, and 1 upper limb.[128]Hobbs CJ. When are burns not accidental? Arch Dis Child. 1986 Apr;61(4):357-61.

Pattern: mixed depth, superficial to partial-thickness, with the deepest burn at the first site of contact (usually face, neck, or upper trunk) and becoming more superficial as it goes down the body.[128]Hobbs CJ. When are burns not accidental? Arch Dis Child. 1986 Apr;61(4):357-61.

Extent: this varies widely, predominantly based on the quantity of liquid involved and the speed and appropriateness of first aid given.
Intentional scalds are typically immersion injuries and are most commonly caused by hot water as opposed to other liquids.[126]Dressler DP, Hozid JL. Thermal injury and child abuse: the medical evidence dilemma. J Burn Care Rehabil. 2001 Mar-Apr;22(2):180-5.

In addition, a home visit may provide essential information (e.g., domestic hot water temperature, height of surface the child is supposed to have reached/climbed onto). All children <2 years of age with a burn that is suspected of being inflicted should have a full skeletal survey, as occult fractures are well described in inflicted burns.[136]Hicks RA, Stolfi A. Skeletal surveys in children with burns caused by child abuse. Pediatr Emerg Care. 2007 May;23(5):308-13.
http://www.ncbi.nlm.nih.gov/pubmed/17505273?tool=bestpractice.com
Typically, an intentional scald has the following features:
Distribution: typical distribution is to the lower extremities, with or without the buttock or perineum.[130]Daria S, Sugar NF, Feldman KW, et al. Into hot water head first: distribution of intentional and unintentional immersion burns. Pediatr Emerg Care. 2004 May;20(5):302-10.

Sometimes there is sparing of the flexures behind the knee or on the buttocks because the child has drawn their legs up tightly to protect themselves or their bottom is pressed against the relatively cold surface of the bath ('doughnut' sign).[138]Purdue GF, Hunt JL, Prescott PR.

Contact and caustic burns
Intentional contact burns are the most common non-scald burn described in abuse. They are most frequently noted on the back, shoulders, and buttocks; are usually clearly demarcated; and in some cases can be precisely matched to the burn agent (e.g., hairdryer or cigarette lighter).[126]Dressler DP, Hozid JL. Thermal injury and child abuse: the medical evidence dilemma. J Burn Care Rehabil. 2001 Mar-Apr;22(2):180-5.

Accidental contact burns to the hands are common in toddlers, typically from grabbing items such as curling tongs or touching hot stoves.
While cigarette burns are a frequently cited contact burn in children, the true characteristics of inflicted versus accidental burns are not well described. Inflicted cigarette burns are circular, full-thickness, approximately 0.8 cm to 1 cm in diameter, and in areas where the child is unlikely to receive an accidental burn, although published evidence for distinguishing accidental and intentional cigarette burns is lacking.[142]Johnson CF. Symbolic scarring and tattooing: unusual manifestations of child abuse. Clin Pediatr. 1994 Jan;33(1):46-9.
http://www.ncbi.nlm.nih.gov/pubmed/8156727?tool=bestpractice.com
Accidental cigarette burns are superficial, may leave no pattern or a cone-shaped mark, and occur on exposed areas of skin.
Abused children may also be subjected to caustic burns (acid or alkali placed in mouth, in eyes, or on skin).[143]Kini N, Lazoritz S, Ott C, et al. Caustic instillation into the ear as a form of child abuse. Am J Emerg Med. 1997 Jul;15(4):442-3.

A detailed history followed by examination of the child's clothes to find the chemical agent is necessary.
Investigations
Children <2 years of age are at particular risk of severe forms of abuse. They may have occult injury and are unable to give their own history of events. A more comprehensive investigation is therefore required in this age group.
Initial investigations in all patients
Skeletal survey: a 22-film skeletal survey (including oblique views of the ribs) should be performed in any child <2 years old where physical abuse is suspected.[10]Christian CW, Committee on Child Abuse and Neglect, American Academy of Pediatrics.

Photo-documentation of any possible injuries: it is vital that appropriate photographs are taken of bruises, burns, bites, and any other cutaneous injuries. In cases of suspected bite, the dental pattern may be reconstructed from photographs. Although the accuracy of forensic dentistry for identifying the 'biter' from a bite mark is uncertain, helpful information may be obtained from a review of bite images. The photographs should be taken with a right-angled measuring device and in at least 2 planes, if the injury is on a curved surface.[36]Fisher-Owens SA, Lukefahr JL, Tate AR, et al.

This investigation should be strongly considered in: children who are <1 year of age in all cases of suspected physical abuse; children with neurological symptoms and/or signs; and all children with head injury. Head CT should also be considered if abusive abdominal injury is found.

Dilated funduscopy: an ophthalmologist must conduct a detailed examination of the fundi using indirect funduscopy with the pupils dilated and RetCam (wide-field digital paediatric retinal imaging). These techniques have the capacity to visualise the periphery of the retina, where retinal haemorrhages in AHT are most often seen.
Brain MRI (± spinal MRI): should be performed within 3 to 5 days if any abnormalities are found on CT brain.[159]Paddock M, Choudhary AK, Jeanes A, et al.

The scan should include diffusion-weighted imaging (DWI), T1- and T2-weighted sequences, and fluid-attenuated inversion recovery (FLAIR). This will enable full delineation of the extent of the injury. DWI sequences may also help with prognosis. MRI should be extended to include the vertebral column if spinal injury is suspected.[155]Kemp AM, Rajaram S, Mann M, et al; Welsh Child Protection Systematic Review Group.

Suspected skeletal injury (in addition to the initial investigation)
Radionuclide bone scan: in some countries this may be performed as an alternative to a repeat skeletal survey in children with suspected fractures when the initial skeletal survey is negative or equivocal. In the US, however, radionuclide scans are rarely used in children. A bone scan becomes positive within 4 hours of a fracture occurring, but remains positive for many months, so does not contribute to the dating of fractures. It is of no value in detecting skull fractures and is less sensitive in identifying metaphyseal lesions. Plain films should also be obtained, and the tests may confirm fractures seen as hotspots. However bone scans have a high sensitivity for identifying rib fractures and can be considered if acute rib fractures are suspected, since acute rib fractures in plain films can be difficult to detect prior to healing.[31]Flaherty EG, Perez-Rossello JM, Levine MA, et al; American Academy of Pediatrics Committee on Child Abuse and Neglect.

Forensic swabs for DNA should also be obtained as they help identification of the perpetrator.
Bruises (in addition to the initial investigation)
Platelet function studies and von Willebrand factor studies may be considered to help rule out a medical cause of bruising.[76]Carpenter SL, Abshire TC, Killough E, et al. Evaluating for suspected child abuse: conditions that predispose to bleeding. Pediatrics. 2022 Oct 1;150(4):e2022059277.
