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.<\/jats:p>","DOI":"10.1177\/1558944718791186","type":"journal-article","created":{"date-parts":[[2018,8,2]],"date-time":"2018-08-02T09:41:38Z","timestamp":1533202898000},"page":"658-663","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Prosthetic
