Reoperation After Operative Fixation of Proximal Interphalangeal Joint Fractures.

Background

The purpose of this study was to determine the reoperation rate and what factors are associated with reoperation of proximal interphalangeal (PIP) joint fractures.

Methods

We identified 161 surgically treated PIP joint fractures between 2004 and 2015 at 2 academic medical systems. Demographic, injury, radiographic, and treatment data that might be associated with reoperation were collected. Bivariate analysis was performed. Factors identified during bivariate analysis with a P < .10 were entered into a multivariable logistic regression analysis.

Results

Of the 161 fingers, 25 underwent revision surgery. Open fracture was independently associated with revision surgery. The most common indication for reoperation was joint stiffness (35%). In a subanalysis of 111 closed fractures, no factors were associated with revision surgery.

Conclusions

Soft tissue injury is a major factor in reoperation after PIP joint fracture dislocation. Specific attention should be paid to persistent subluxation because this may predispose to early arthrosis.
