Clinical outcomes of arthrodesis and arthroplasty for the treatment of posttraumatic wrist arthritis

Abstract

Purpose: To compare clinical outcomes of wrist arthrodesis and total wrist arthroplasty in the treatment of pancarpal posttraumatic arthritis. We hypothesized that arthroplasty would demonstrate better clinical outcomes than wrist arthrodesis.

Methods: We performed a retrospective review of 22 patients treated (15 arthrodeses and 7 arthroplasties) for pancarpal posttraumatic arthritis. We measured clinical outcomes with the visual analog pain scale; Disabilities of the Arm, Shoulder, and Hand questionnaire; the Patient-Rated Wrist Evaluation; and a study-specific questionnaire. Postoperative complications were recorded from chart review.

Results: Mean follow-up was 68 months for arthrodesis and 56 months for arthroplasty. The mean visual analog scale pain score was 2 for each group. The mean Disabilities of the Arm, Shoulder, and Hand score was 38 for the arthrodesis group and 29 for the arthroplasty group. The mean Patient-Rated Wrist Evaluation was 73 for the arthrodesis group and 31 for the arthroplasty group. The results from the study-specific questionnaire revealed that the majority of patients in both groups were satisfied. Complication rates were similar in both groups.

Conclusions: Total wrist arthroplasty as an alternative to arthrodesis for the treatment of pancarpal posttraumatic arthritis may offer improved functional outcomes.

Type of study/level of evidence: Therapeutic III.
