Joint-Preserving Surgery for Hyperextension Deformity of the Hallux Interphalangeal Joint in a Patient with Rheumatoid Arthritis

Figure 3

Postoperative weight-bearing radiographs of the foot. (a) Anteroposterior view of the foot showing improved hallux valgus deformity and congruent metatarsophalangeal joint. (b, c) Lateral view of the foot showing improvement of the elevated first metatarsal, plantar deviation of the proximal phalanx, and interphalangeal hyperextension. The two arrowheads indicate the distance between two dorsal cortices of the first and second metatarsals, indicating improvement of the elevated first metatarsal compared with Figure 2(c). The cross indicates the approximate center of the metatarsal head. Dotted lines drawn along the naviculocuneiform and tarsometatarsal joints demonstrate the improvement of plantar flexion by approximately 10° after the Cotton osteotomy.
