Abstract

Purpose To compare outcomes of prosthetic arthroplasty versus arthrodesis to treat index finger proximal interphalangeal (PIP) joint arthritis. Methods Patients with osteoarthritis or posttraumatic arthritis of index finger PIP joints were evaluated. Digit range of motion, grip and pinch strength, patient-rated pain and satisfaction scores, Michigan Hand Questionnaire scores, and complications were recorded. Results A total of 79 finger PIP joints were followed for a median of 67 months overall (72 months for arthroplasty and 8 months for the arthrodesis group). Sixty-five were treated with arthroplasty and 14 with arthrodesis. Patients undergoing arthroplasty experienced no significant postoperative change in PIP joint range of motion whereas all preoperative PIP joint motion was eliminated after arthrodesis. Patients undergoing arthroplasty experienced significant postoperative improvement in opposition pinch. In contrast, patients undergoing arthrodesis experienced significant improvement in both opposition and apposition pinch. There were no differences in pain relief, satisfaction, or Michigan Hand Questionnaire scores between treatment groups. Patients undergoing arthroplasty had a significantly greater mean number of complications per year and mean number of complications in the first year postoperatively. There was a 4.3 times increased risk of complication in patients undergoing arthroplasty versus arthrodesis, and Kaplan-Meier analysis revealed a shorter time to first complication among patients undergoing arthroplasty. Conclusions The decision for prosthetic arthroplasty versus arthrodesis in the index finger of patients with osteoarthritis or posttraumatic arthritis must be made with patient goals in mind and in light of greater risk of complications associated with arthroplasty. Type of study/level of evidence Therapeutic III.
