Factors Associated With Complications and Reoperations in Distal Interphalangeal Joint Fusion.

Abstract

This objective of this study was to identify risk factors for complications and reoperations after distal interphalangeal joint arthrodesis. A retrospective study was performed of all patients who underwent isolated distal interphalangeal joint arthrodesis between 2006 and 2019 at an integrated health system consisting of 2 Level I trauma centers and 2 community teaching hospitals. Demographics, implant, and treatment characteristics were collected from the medical record. The primary outcome was complication, and the secondary outcome was reoperation. Bivariate analyses were used to identify factors associated with our study outcomes. A total of 209 fingers in 187 patients were included in this study. The radiographic union rate of our cohort was 96.7%. Forty patients (21.4%) had a postoperative complication, and 30 patients (16.0%) underwent reoperation. The use of a graft was significantly associated with decreased risk of reoperation, however, smoking, diabetes mellitus and type of implant were not associated with complication or reoperation. Although there are no specific risk factors associated with negative outcomes, the use of graft was associated with a decreased reoperation rate. III, Therapeutic.
