Total wrist arthroplasty: a systematic review of the evidence from the last 5 years

The treatment of arthritis of the wrist

Arthritis of the wrist is a painful disabling condition that has various causes and presentations. The traditional treatment has been a total wrist fusion at a price of the elimination of movement. However, forms of treatment which allow the preservation of movement are now preferred. Modern arthroplasties of the wrist are still not sufficiently robust to meet the demands of many patients, nor do they restore normal kinematics of the wrist. A preferable compromise may be selective excision and partial fusion of the wrist using knowledge of the aetiology and pattern of degenerative change to identify which joints can be sacrificed and which can be preserved. This article provides an overview of the treatment options available for patients with arthritis of the wrist and an algorithm for selecting an appropriate surgical strategy.

Long-term functional outcomes after bilateral total wrist arthrodesis

PURPOSE

To report on the long-term outcomes of bilateral total wrist arthrodeses.

METHODS

We conducted a review of all living patients who underwent bilateral wrist arthrodeses from 1980 to 2010 within a single institution. Outcome measures included pain, Disabilities of the Arm, Shoulder, and Hand questionnaire, Patient-Rated Wrist Evaluation, Michigan Hand Questionnaire, satisfaction scores, complications, and revision surgeries.

RESULTS

Thirteen patients (26 wrists) were treated with an average follow-up of 14 years (range, 3-28 y). Average time for contralateral wrist arthrodesis was 16 months after initial wrist arthrodesis. Eleven wrists had undergone prior surgery. Eleven patients had a primary diagnosis of inflammatory arthritis. Wrists were fused from 5° flexion to 30° extension, with all but one patient's wrist fused within 10° of the contralateral wrist. There was a significant improvement in postoperative grip strength and pain levels. Postoperative Disabilities of the Arm, Shoulder, and Hand, Patient-Rated Wrist Evaluation, and Michigan Hand Questionnaire scores were 21, 29, and 73, respectively. Increasing age, preoperative steroid usage, and concomitant shoulder or elbow disorders were associated with worse outcomes. Twelve patients (93%) were satisfied and would repeat the surgery and 9 returned to full-time work. The major functional limitation was turning a doorknob or tight jar lid. Seven patients underwent additional surgery including 5 revision arthrodeses and 2 plate removals. Revision surgeries were more common in patients with prior surgeries or preoperative steroid usage, women, smokers, those with ipsilateral elbow dysfunction, and those with fixation with a dorsal locking plate.

CONCLUSIONS

Bilateral total wrist arthrodesis improved pain while enabling patients with severe carpal arthrosis to maintain a satisfactory level of extremity function and quality of life. In general, patients adapted and were satisfied with functional capabilities. This is a viable salvage option for patients with severe bilateral disease.
