summary Hallux Valgus, commonly referred to as a bunion, is a complex valgus deformity of the first ray that can cause medial big toe pain and difficulty with shoe wear. Diagnosis is made clinically with presence of a hallux that rests in a valgus and pronated position. Radiographs of the foot are obtained to identify the severity of the disease and for surgical planning. Treatment can be nonoperative with shoe modifications for mild and minimally symptomatic cases. Surgical management is indicated for progressive deformity and difficulty with shoe wear. Epidemiology Demographics more common in women Risk factors intrinsic genetic predisposition 70% of pts with hallux valgus have family history increased distal metaphyseal articular angle (DMAA) ligamentous laxity (1st tarso-metatarsal joint instability) convex metatarsal head 2nd toe deformity/amputation pes planus rheumatoid arthritis cerebral palsy extrinsic shoes with high heel and narrow toe box Etiology Two forms exist adult hallux valgus adolescent & juvenile hallux valgus Pathoanatamy valgus deviation of phalanx promotes varus position of metatarsal the metatarsal head displaces medially, leaving the sesamoid complex laterally translated relative to the metatarsal head sesamoids remain within the respective head of the flexor hallucis brevis tendon and are attached to the base of the proximal phalanx via the sesamoido-phalangeal ligament this lateral displacement can lead to transfer metatarsalgia due to shift in weight bearing medial MTP joint capsule becomes stretched and attenuated while the lateral capsule becomes contracted adductor tendon becomes deforming force inserts on fibular sesamoid and lateral aspect of proximal phalanx lateral deviation of EHL further contributes to deformity plantar and lateral migration of the abductor hallucis causes muscle to plantar flex and pronate phalanx windlass mechanism becomes less effective leads to transfer metatarsalgia Associated conditions hammer toe deformity callosities pes planus associated with deformity progression Juvenile and Adolescent Hallux valgus factors that differentiate juvenile / adolescent hallux valgus from adults often bilateral and familial pain usually not primary complaint varus of first MT with widened IMA usually present DMAA usually increased often associated with flexible flatfoot complications recurrence is most common complication (>50%), also overcorrection and hallux varus Anatomy Pathoanatomy cascade Presentation Symptoms presents with difficulty with shoe wear due to medial eminence pain over prominence at MTP joint compression of digital nerve may cause symptoms Physical exam Hallux rests in valgus and pronated due to deforming forces illustrated above examine entire first ray for 1st MTP ROM 1st tarsometatarsal mobility callous formation sesamoid pain/arthritis evaluate associated deformities pes planus lesser toe deformities midfoot and hindfoot conditions Imaging Radiographs views standard series should include weight bearing AP, Lat, and oblique views sesamoid view can be useful findings lateral displacement of sesamoids joint congruency and degenerative changes can be evaluated radiographic parameters (see below) guide treatment Radiographic Measurements in Hallux Valgus Hallux valgus (HVA) Long axis of 1st MT and prox. phalanx Identifies MTP deformity Normal < 15° Intermetatarsal angle (IMA) Between long axis of 1st and 2nd MT Normal < 9 ° Distal metatarsal articular (DMAA) Between 1st MT axis and line through base of distal articular cap Identifies MTP joint incongruity Normal < 10° Hallux valgus interphalangeus (HVI) Between long. axis of distal phalanx and proximal phalanx Normal < 10° Treatment - Adult Hallux Valgus Nonoperative shoe modification/ pads/ spacers/orthoses indications first line treatment orthoses more helpful in patients with pes planus or metatarsalgia Operative surgical correction indications when symptoms present despite shoe modification do not perform for cosmetic reasons alone technique soft tissue procedure indicated in very mild disease in young female (almost never) distal osteotomy indicated in mild disease (IMA < 13) proximal or combined osteotomy indicated in more moderate disease (IMA > 13) 1st TMT arthrodesis arthritis at TMT joint or instability fusion procedures indicated in severe deformity/spasticity/arthritis MTP resection arthroplasty only indicated in elderly patients with low functional demands Treatment - Juvenile and Adolescent Hallux valgus Nonoperative shoe modification indications pursue nonoperative management until physis closes Operative surgical correction indications best to wait until skeletal maturity to operate can not perform proximal metatarsal osteotomies if physis is open (cuneiform osteotomy OK) surgery indicated in symptomatic patients with an IMA > 10° and HVA of > 20° consider double MT osteotomy in adolescent patients with increased DMAA technique soft tissue procedure alone not successful similar to adults if physis is closed (except in severe deformity) Techniques Soft Tissue Procedures modified McBride indications goal is to correct an incongruent MTP joint (phalanx not lined up with articular cartilage of MT head).
