![]() This is usually achieved by the use of soft and wide shoes. Non-surgical treatment involves the use of accommodative footwear. Hallux valgus may be a result of metatarsus primus varus, and surgical correction is often based on this theory. The combined deformities are present to some degree in most patients. ![]() There is a close association between the degree of metatarsus primus varus and hallux valgus. second metatarsal dorsal clawing and cortical hyperostosis due to increased stress from altered biomechanics.first MTP joint medial soft tissue swelling representing synovial thickening and bursitis (clinically presents as a bunion).secondary osteoarthritis of the first MTP joint, usually with a medial osteophyte.lateral subluxation of the hallux sesamoids. ![]() dorsal angulation of the first metatarsal (on the lateral projection).the prominence of the medial aspect of the first metatarsal head is referred to as the medial eminence.lateral subluxation of the base of the first proximal phalanx with respect to the head of the first metatarsal.Other associated radiographic features include: The intermetatarsal angle should be <9° on a weight-bearing foot radiograph 2. Radiographic features Plain radiographĪ normal first metatarsophalangeal angle is ≤15° on an AP weight-bearing foot radiograph 2 anything greater indicates hallux valgus where the head of the first metatarsal is deviated medially. It is usually due to metatarsus primus varus which is a medial deviation or adduction of the first metatarsal with an increased first-second metatarsal angle. A hallux valgus (plural: halluces valgi) is a fixed abduction of the first metatarsophalangeal joint of the great toe.
