Abstract: Deficiency of the proximal pole of the scaphoid due to fracture or necrosis was treated by costo-osteochondral replacement arthroplasty using rib bone/cartilage autografts in 22 patients who were followed prospectively and assessed at a median 24 month follow-up (range, 12–72 months). Improvement of wrist function occurred in all patients with increased motion, improved grip strength and less pain. The average modified Green and O’Brien Wrist Function Score improved from 53 out of 100 preoperatively to 80 at the most recent review. All patients were graded fair or poor at initial review and all but three improved to good or excellent at the most recent assessment. Despite the absence of the scapholunate ligament, carpal alignment did not deteriorate in any patient and there were no graft non-unions or significant complications. In the short and medium term a costo-osteochondral autograft can satisfactorily restore mechanical integrity of the scaphoid proximal pole and maintain wrist motion while avoiding the potential complications of alternative replacement arthroplasty techniques.
