The Weil osteotomy for treatment of dislocated lesser metatarsophalangeal joints: good outcome in 21 patients with 42 osteotomies.
Hardly any surgical methods are available for metatarsalgia caused by a dislocated lesser metatarsophalangeal joint (MTP) that do not sacrifice the joint. We reviewed retrospectively the outcome of 60 metatarsal Weil osteotomies for correction of dislocated lesser MTP joints in 31 patients. Between 1995 and 1996, 31 consecutive patients were treated with a Weil osteotomy at 2 institutions. The Weil osteotomy is an oblique osteotomy of the metatarsal neck and shaft, parallel to the ground surface, that controls shortening of the metatarsal by internal fixation with screws or pins. At an average final follow-up of 30 (24-44) months, all patients were interviewed, using a standardized questionnaire based on the AOFAS Lesser Metatarsophalangeal-Interphalangeal Scale. Recurrent or transfer metatarsalgia, formation of callus, mobility and dislocation of the MTP were noted on physical examination. Dorsoplantar and lateral weightbearing radiographs taken preoperatively and at the time of final follow-up were examined for alignment of the metatarsal heads, subluxation or dislocation and for evidence of nonunion, or malunion of the metatarsal osteotomy. We had excellent results in 21 patients (42 osteotomies). A major complication was plantar penetrating hardware in 10 cases (3 screws and 7 pins). We conclude that the Weil osteotomy is a good method for correcting metatarsalgia caused by dislocation of the MTP joint.
