Prosthetic Arthroplasty Versus Arthrodesis for @entity571 and XXXX of the Index Finger Proximal Interphalangeal Joint.

@entity1 @entity625 @entity571 @entity6520 @entity158
PURPOSE: To compare outcomes of prosthetic arthroplasty versus arthrodesis to treat index finger proximal interphalangeal (PIP) joint @entity625 . METHODS: @entity1 with @entity571 or @entity625 of index finger PIP joints were evaluated. Digit range of motion, grip and pinch strength, @entity1 -rated @entity158 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 mo for arthroplasty and 8 mo for the arthrodesis group). Sixty-five were treated with arthroplasty and 14 with arthrodesis. @entity1 undergoing arthroplasty experienced no significant postoperative change in PIP joint range of motion whereas all preoperative @entity6520 was eliminated after arthrodesis. @entity1 undergoing arthroplasty experienced significant postoperative improvement in opposition pinch. In contrast, @entity1 undergoing arthrodesis experienced significant improvement in both opposition and apposition pinch. There were no differences in @entity158 relief, satisfaction, or Michigan Hand Questionnaire scores between treatment groups. @entity1 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 @entity1 undergoing arthroplasty versus arthrodesis, and Kaplan-Meier analysis revealed a shorter time to first complication among @entity1 undergoing arthroplasty. CONCLUSIONS: The decision for prosthetic arthroplasty versus arthrodesis in the index finger of @entity1 with @entity571 or @entity625 must be made with @entity1 goals in mind and in light of greater risk of complications associated with arthroplasty. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.
