Chevron osteotomy of fifth metatarsophalangeal joint. A, Suggested incision. B, Inverted-L–shaped capsular incision transecting abductor digiti minimi. C, Amount of lateral eminence removed, not quite flush with shaft. D, Dorsal limb of osteotomy begins at centering hole; care is taken to prevent blade from “walking” into capital fragment distally. E, Translation of capital fragment medially 2 to 4 mm; it is tilted dorsally if callus is beneath fifth metatarsal head. F, Two small Kirschner wires improve stability. Overhanging lateral wedge of proximal fragment is removed, taking care not to enter entrance portal of Kirschner wires. G, Abductor digiti minimi is repositioned laterally to prevent medial subluxation of toe. SEE TECHNIQUE 84.25.
