Abstract

Background: Proximal interphalangeal (PIP) fracture-dislocation is a relatively common injury that results from “jamming” a finger. Treatment hinges on the degree of articular surface involvement, which determines stability of the joint. For unstable injuries, a variety of surgical interventions have been described including extension block pinning, open reduction internal fixation, volar plate arthroplasty, static or dynamic external fixation, and hemi-hamate reconstruction. We present the case of an unstable, subacute ring finger PIP dorsal fracture dislocation for which the above options were not possible or desirable to the patient.
Methods: We performed temporary bridge plate fixation of the joint, based on the success of a similar procedure used to treat comminuted and unstable distal radius fractures.
Results: The procedure allowed immediate return to work, which was the patients’ primary goal, and resulted in a reasonable short-term outcome, similar to other mentioned procedures.
Conclusion: Temporary bridge plate fixation can be considered among treatment choices for PIP fracture dislocation when other, more established options are not possible or desirable.
