Prosthetic Arthroplasty of Proximal Interphalangeal Joints for Treatment of Osteoarthritis and Posttraumatic Arthritis: Systematic Review and Meta-Analysis Comparing the Three Ulnar Digits With the Index Finger.

Journal Article (Journal Article;Systematic Review)

Background: It is common teaching that treatment of index finger alone is a relative contraindication for arthroplasty of the proximal interphalangeal joint (PIPJ). However, limited data exist reporting the digit-specific complication of PIPJ arthroplasty for the treatment of osteoarthritis or posttraumatic arthritis. The purpose of this article is to perform a systematic review and meta-analysis of the literature to assess whether the 3 ulnar digits may bear a similar instability and complication profile. Methods: Systematic searches of the MEDLINE, EMBASE, and Cochrane computerized literature databases were performed for PIPJ arthroplasty specifying by digit. We reviewed both descriptive and quantitative data to: (1) report aggregate instability and instability-related complications after non-index digit PIPJ arthroplasty; and (2) perform statistical testing to assess relative rates by digit and compared with index digits. Results: Computerized search generated 385 original articles. Five studies reporting digit-specific instability-related outcomes of silicone, pyrocarbon, or metal surface arthroplasty on 177 digits were included in the review. Meta-analysis demonstrated a 29% instability rate for long digits (n = 65), 6% for ring digits (n = 53), and 6% for small digits (n = 17), compared with 33% for index digits (n = 42). There was no difference in the overall deformity, instability, and complication rates of long versus index fingers (P = .65). Conclusions: Instability-related deformity and complication rates of long finger PIPJ arthroplasty may not be different from that of the index finger. Treatment of the long finger may be a relative contraindication to PIPJ arthroplasty. Future biomechanical and clinical studies are needed.
