The surgical treatment of Kienbock's disease by radius and ulna metaphyseal core decompression

We present a new surgical procedure, metaphyseal core decompression, to tre at Kienbock's disease. Twenty-two patients were treated between 1976 and 19 88 and were retrospectively reviewed. Sixteen were male and 6 female with a n average age of 30 years (range, 18-64 years). The surgical technique invo lved curettage of the distal radius and ulna metaphyseal bone through small cortical windows. The average follow-up period was 10 years (range, 6-16 y ears). No postoperative complications were noted and no patient underwent a dditional surgical procedure. Sixteen patients were pain-free; 4 noted occa sional pain. Twenty returned to their prior occupation. One patient had mod erate pain and altered his occupation. Another had increasing pain and had x-ray evidence of advanced intercarpal arthritis. The average are of wrist extension and flexion was 77% of the opposite wrist and the average grip st rength was 75%. Long-term follow-up monitoring indicates that the metaphyse al core decompression produces results at least as good as other surgical p rocedures without any postoperative complications.
