Surgery for symptomatic Freiberg's disease: extraarticular dorsal closing-wedge osteotomy in 13 patients followed for 2-4 years.

From 1992 through 1995, we have treated 13 patients (10 men) with Freiberg's disease by debridement and dorsal closing-wedge osteotomy of the metatarsal neck. The lesion was located in the second metatarsal head in 10 patients and in the third metatarsal head in 3. After osteotomy, the lesion was away from the joint, so that the smooth and healthy articular cartilage of the metatarsal head faced the phalangeal cartilage. The average follow-up period was 40 (28-54) months. The subjective outcome was good or excellent in 11 patients, fair in 1, and poor in 1. We found MRI useful in determining the extent of the lesion when planning correction.
