Cavus foot correction in adults by dorsal closing wedge osteotomy

Twelve patients (13 feet) who underwent dorsal closing wedge osteotomy for cavus foot deformity were re-examined clinically and radiographically 46 months after surgery (range, 24 to 80 months). A dorsally based bone wedge, sized according to the deformity on the preoperative radiographs, was excised between the Lisfranc and Chopart joint lines. Eight patients (nine feet) were satisfied with the procedure. Although significant improvement of both symptoms and foot alignment was achieved, most patients continued to experience mild to moderate pain postoperatively. The outcome seems not to be directly related to the achieved surgical correction.
