Radial recession osteotomy for Kienböck's disease.

Abstract

Sixty-eight patients underwent radial recession osteotomy for avascular necrosis of the lunate were retrospectively evaluated after an average follow-up period of 52 months. Twenty-five patients had undergone 1 or more additional procedures concurrently for treatment of Kienböck's disease. Pain diminished in 93% of patients, grip strength improved, and wrist motion was preserved; 75% of patients continued in their original occupations, including heavy labor. Surgical complications were uncommon. Four patients subsequently underwent salvage procedures, including 2 total wrist arthrodeses. Three of these 4 patients were receiving workers' compensation. One third of patients demonstrated lunate healing after joint leveling. Preliminary results suggest that concomitant lunate revascularization or vascularized bone grafting may improve the radiographic result. With rare exceptions, radial recession osteotomy relieves pain and improves function in Kienböck's disease.
