Coverage of Palmar Mini Plates with Flexor Pulleys in the Treatment of Dorsal Fracture-Subluxation of the Proximal Interphalangeal Joint.

Introduction

Dorsal fracture dislocations (DFD) of the proximal interphalangeal joint (PIPJ) are challenging fractures. A palmar surgical approach and plate fixation has a high complication rate, including flexor contractions, reduction of range of motion (ROM) and secondary need for plate removal.

Methods

We use the flexor tendon pulleys to cover the mini plate with the assumption that it may reduce the adhesion between the mini plates and the tendons and reduce postoperative complications. We present the outcomes of using this technique in eight patients.

Results

All patients had an excellent outcome at a mean follow-up of 17 months, and none required removal of the implants.

Conclusions

This study presents a surgical technique that may potentially reduce the high complication rate found after ORIF for treatment of DFD of the PIPJ. Therefore, improving the clinical outcomes after this type of surgery. Level of Evidence: Level IV (Therapeutic).
