reassurance
Treatment of torsional problems in healthy children is both unnecessary and ineffective.[1]Staheli LT. Rotational problems in children. Instr Course Lect. 1994;43:199-209. http://www.ncbi.nlm.nih.gov/pubmed/9097150?tool=bestpractice.com [2]Staheli LT, Corbett M, Wyss C, et al.

Twister cables, night splints, shoe wedges, physical therapy, or a combination of these is ineffective at altering limb alignment or normalizing gait.[1]Staheli LT. Rotational problems in children.

orthopedist referral
Treatment recommended for SOME patients in selected patient group
Referral to an orthopedist should be considered for: 1) families who require additional reassurance; 2) uncertain diagnosis or inconclusive screening exam; 3) children with stiff forefoot adductus; and 4) older children or adolescents with leg pain or disability.
observation
Initial treatment is parental reassurance and education. Arrangements for regular follow-up should be provided. Corrective shoe wedges, night splints, twister cables, and physical therapy have not been shown to alter the natural history or ensure normal gait.[1]Staheli LT. Rotational problems in children. Instr Course Lect. 1994;43:199-209. http://www.ncbi.nlm.nih.gov/pubmed/9097150?tool=bestpractice.com [3]Engel GM, Staheli LT.

In otherwise healthy children, operative treatment consisting of derotational osteotomy is rarely indicated.
surgical correction
Treatment recommended for SOME patients in selected patient group
Indicated in selected children ages >8 years with significant deformity that disrupts gait function, and with thigh-foot angle >3 standard deviations beyond the mean.[26]Davids JR, Davis RB, Jameson LC, et al. Surgical management of persistent intoeing gait due to increased internal tibial torsion in children. J Pediatr Orthop. J Pediatr Orthop. 2014 Jun;34(4):467-73 http://www.ncbi.nlm.nih.gov/pubmed/24531409?tool=bestpractice.com [28]MacWilliams BA, McMulkin ML, Baird GO, et al. Distal tibial rotation osteotomies normalize frontal plane knee moments. J Bone Joint Surg Am. 2010 Dec 1;92(17):2835-42. http://www.ncbi.nlm.nih.gov/pubmed/21123614?tool=bestpractice.com [79]Staheli LT. Torsion: treatment indications. Clin Orthop Relat Res. 1989 Oct;(247):61-6. http://www.ncbi.nlm.nih.gov/pubmed/2676305?tool=bestpractice.com [80]Mooney JF 3rd. Lower extremity rotational and angular issues in children. Pediatr Clin North Am. 2014 Dec;61(6):1175-83. http://www.ncbi.nlm.nih.gov/pubmed/25439018?tool=bestpractice.com Femoral alignment must be considered before surgical treatment, as femoral rotation can aggravate or compensate for tibial torsion.
Surgical correction has classically consisted of a derotational osteotomy, which involves cutting the bone, acutely correcting the rotational deformity, and fixing of the bone fragments with orthopedic hardware. Recovery requires a period of nonweight bearing to the operative extremity, usually 6 weeks, and possible casting. A novel surgical option is rotational guided growth. See Emerging treaments.
In rare cases (<1%) medial femoral torsion may persist and be severe enough to cause disability in late childhood or adolescence. Surgical treatment is never indicated prophylactically. Surgical correction, consisting of a rotational femoral osteotomy (usually performed at the proximal femur), may be indicated in older children with severe deformities >3 standard deviations beyond the mean, medial hip rotation 80° to 90° or lateral rotation 0°, external rotation ≤20°, and significant functional disability.[79]Staheli LT. Torsion: treatment indications. Clin Orthop Relat Res. 1989 Oct;(247):61-6. http://www.ncbi.nlm.nih.gov/pubmed/2676305?tool=bestpractice.com [80]Mooney JF 3rd.

surgical correction
Out-toeing due to lateral tibial torsion is generally more problematic than medial tibial torsion and more likely to require operative correction. Indicated in selected children ages >8 years, with significant functional deformity, and with thigh-foot angle >40° or 3 standard deviations beyond the mean.[79]Staheli LT. Torsion: treatment indications. Clin Orthop Relat Res. 1989 Oct;(247):61-6. http://www.ncbi.nlm.nih.gov/pubmed/2676305?tool=bestpractice.com [80]Mooney JF 3rd.

specific comorbidity
conservative management ± physical therapy
Excessive lateral tibial torsion and medial femoral torsion (miserable malalignment) associated with anterior knee symptoms, including patellofemoral pain, patella subluxation, or, rarely, dislocation, are initially treated conservatively. Physical therapy is prescribed for knee pain and patella instability. If pain or instability persist after a course of physical therapy, surgical treatment with derotation tibial and femoral osteotomy may be considered.
surgery or botulinum toxin
Torsional deformity is just one factor that contributes to pathologic gait in patients with cerebral palsy.[81]Gage JR, Schwartz M. Pathological gait and lever-arm dysfunction. In: Gage JR, ed. The treatment of gait problems in cerebral palsy. London, UK: Mac Keith Press; 2004:180-204. Muscle imbalance, spasticity, and contractures may require tone-reducing medications (e.g., onabotulinumtoxinA) or soft-tissue procedures (e.g., tenotomy, tendon transfer, and muscle release) before bony procedures.[11]Fraser RK, Menelaus MB. The management of tibial torsion in patients with spina bifida. J Bone Joint Surg Br. 1993 May;75(3):495-7. http://www.bjj.boneandjoint.org.uk/content/75-B/3/495 http://www.ncbi.nlm.nih.gov/pubmed/8496230?tool=bestpractice.com [82]Pascual-Pascual SI, Pascual-Castroviejo I, Ruiz PJ.

Primary options
onabotulinumtoxinA: consult specialist for guidance on dose
stretching and serial casting
A flexible foot (the forefoot can be passively abducted so that heel-bisector line is beyond second web space) can be observed. A flexible foot that corrects to midline may be treated with a home stretching program.[88]Canadian Paediatric Society. Footwear for children. Feb 2009 [internet publication]. https://www.cps.ca/en/documents/position/footwear-for-children A foot that does not correct to midline or does not improve with stretching may be serially casted every 1 to 2 weeks. Casting results are best when initiated before age 8 months.
surgery
Treatment recommended for SOME patients in selected patient group
Surgery is occasionally considered in children >4 years old for feet with severe deformity.
orthopedic referral
Require referral to an orthopedist for treatment.
reassurance
Flexible, painless, flat feet are typically not pathologic and do not predispose a child to foot pain as an adult. Flexible, asymptomatic flat feet do not require intervention and there is no evidence that corrective shoes or inserts are effective for painless flat feet.[46]Rerucha CM, Dickison C, Baird DC. Lower extremity abnormalities in children. Am Fam Physician. 2017 Aug 15;96(4):226-33. https://www.aafp.org/afp/2017/0815/p226.html http://www.ncbi.nlm.nih.gov/pubmed/28925669?tool=bestpractice.com [88]Canadian Paediatric Society. Footwear for children. Feb 2009 [internet publication]. https://www.cps.ca/en/documents/position/footwear-for-children
supportive care
Initial treatment is reassurance and shoes with well-formed arch support in older children. A custom orthotic may be prescribed if pain persists despite the use of an off-the-shelf orthotic. Flexible flat feet associated with hindfoot pain resulting from a contracted gastrocnemius-soleus may be treated with Achilles tendon stretching exercises.
orthopedic referral
Treatment recommended for SOME patients in selected patient group
Painful and stiff flat feet require referral to an orthopedist.
observation
For children <3 years old, observation every 3 to 6 months is recommended.
bracing
Treatment recommended for SOME patients in selected patient group
Bracing (with a medial upright knee-ankle-foot orthosis) has limited effectiveness in certain patients in the early stages of the disease.
surgery
Treatment recommended for SOME patients in selected patient group
Surgical correction is required for brace failure or for severe deformity before age 4 years.
orthopedic referral
Surgery to restore the normal anatomic alignment is the mainstay of treatment.
