Background: Weil osteotomy is a type of distal osteotomy for the treatment of lesser metatarsalgia by shortening the metatarsal length. We applied Weil and dorsal closing wedge osteotomy for the treatment of Freiberg's disease.

Methods: Between September 1, 2006, and December 31, 2011, we performed Weil and dorsal closing wedge osteotomy of the second metatarsal in 15 feet of 15 patients (12 women, three men) diagnosed as having Freiberg's disease. The mean patient age was 29 years (range, 19–51 years), and mean follow-up was 47 months (range, 36–72 months). Postoperative shortening of the metatarsal length was measured by comparing preoperative and postoperative radiographs. Visual analog scale scores, American Orthopedic Foot and Ankle Society lesser metatarsophalangeal-interphalangeal scores, and the passive range of motion of the metatarsophalangeal joint were evaluated at 24 months.

Results: The mean postoperative shortening of the metatarsal length was 3.2 mm. The mean visual analog scale and American Orthopedic Foot and Ankle Society scores were 7.2 and 52.4 points preoperatively and 2.1 and 78.2 points at 24 months, respectively (P < .05). The mean range of motion of the metatarsophalangeal joint increased from 29.4° preoperatively to 46.5° postoperatively (P < .05). Various degrees of remodeling were observed at the dorsum of the metatarsal head at 24 months.

Conclusions: Weil and dorsal closing wedge osteotomy of the metatarsal seems to be effective for treating Freiberg's disease. It improves pain and function in terms of shortening the metatarsal length and restoring the metatarsophalangeal joint.
