Surgical reconstruction of the diabetic foot: a salvage approach for midfoot collapse.

Abstract

Between 1985 and 1993, 18 patients representing 21 feet underwent surgical reconstruction for diabetic neuroarthropathy with collapse of the midfoot. Forty-seven percent (10/21) of these feet presented with plantar pressure ulcers. Reconstruction involved reduction and fusion of collapsed joints, using internal fixation to restore foot shape and improve weightbearing alignment. The average follow-up in these patients was 28 months (range, 6-84 months). Limb salvage was obtained in 18 of 21 feet. Average time to radiographic union was 5 months (range, 3-9 months). Improvement in shoe fit and ambulatory status was noted for 13 of the 15 patients who had successful reconstruction. Forty-seven percent of the reviewed cases were without any complication throughout their postoperative course. Seventy percent of the presenting ulcers healed without incident. There were no recurrent midfoot ulcers.
