The modified clayton-mannerfelt arthrodesis of the wrist in rheumatoid arthritis: operative technique and report on 93 cases.
ABSTRACT Arthrodesis of a painful and destroyed wrist is one of the key operations in patients with rheumatoid arthritis. Clayton is given credit for the first description of an operative technique of wrist arthrodesis by means of an intramedullary Steinmann pin. Mannerfelt popularized this technique by using a Rush pin and additional fixation with staples. The aim of the present article is to give a detailed description of the operative technique used in our hospital. Over a period of 13 years, 104 modified Clayton-Mannerfelt arthrodeses were performed in 87 patients with rheumatoid arthritis. Ninety-three wrists were reviewed clinically and radiographically. The patients had high fusion rates and a reliable reduction in preoperative pain, with a low rate of complications. The pin technique is more versatile than standard wrist arthrodesis plates, and the wrist can be positioned according to the needs of the patient. This technique seems to be a good alternative to conventional wrist arthrodesis using an arthrodesis plate in wrists destroyed by rheumatoid arthritis, even in situations with difficult bone stock. In most cases, it is not necessary to remove the hardware.

ABSTRACT: We studied a technical modification of Mannerfelt's total wrist fusion technique in a series of 19 wrists. A fully intramedullary technique without dorsal carpal fixation was used to protect the extensor tendons. Two intramedullary Rush pins without dorsal staples were used during the arthrodesis procedure. Nineteen rheumatoid arthritis wrists (2 bilateral cases) were reviewed with a mean follow-up of 4.9 years (range 2-10 years). Clinical outcomes were assessed using the VAS pain scale, DASH-score and wrist strength measurements. Wrist fusion was assessed on AP and lateral X-rays of the wrist. The position of the carpal Rush pin entry points and distal hook orientation were also assessed. Pain was 8.9 preoperatively and 1.1 at the last follow-up with 95% patients satisfied. Mean DASH-score was 46.9 points. The pinch strength was 79% and the grip strength was 68% of the contralateral wrist. Carpal height, carpal anterior subluxation and ulnar deviation were stable at the last follow-up. All of the wrists were in straight position and no extensor tendon ruptures were noted. Fusion was complete in all cases within 6 to 12 weeks, except in one case. The technical modification proposed in the current study -intraosseous fixation only- appears to be a good alternative to Mannerfelt's original technique. Every case treated with this modified technique had good functional results and none required pin removal.Chirurgie de la Main 09/2014; 33(5). DOI:10.1016/j.main.2014.06.006 · 0.25 Impact Factor

ABSTRACT: In rheumatoid arthritis the small joints of the feet and hands are the first targets of the autoimmune process. In about one half of the patient the wrist is involved in the first stages of the disease (two years) increasing up to nearly 90 percent after a decade often including both sides. Osteoarthritis of the wrist is one of the most common conditions encountered by hand surgeons. One aim of all treatment options is to achieve the best possible hand function without pain. If conservative treatment fails, operative treatment is necessary. Choice of surgical treatment depends on the soft tissue and bone situation. Techniques can be differentiated by joint preservation or joint replacement. The first include radio-synoviorthesis, synovectomy and tendon repair, the latter resection-arthroplasty, total joint arthroplasty and arthrodesis. In this paper arthrodesis of the wrist as one treatment option is reviewed.09/2014; 5(4):512-5. DOI:10.5312/wjo.v5.i4.512
