Flexor Digitorum Profundus injuries or ‘Jersey finger’ results from forceful hyperextension of DIPJ with the FDP in maximal contraction. This case report examines bilateral sequential FDP avulsion fractures and focuses on a novel surgical repair using a 1.3mm Synthes LC-DCP in a hook plate fashion which achieved anatomical reduction, healing and full return of function.
Our patient had excellent outcomes following his injury and subsequent surgery to near normal functional levels. Normal PIPJ range of motion and near normal DIPJ range of motion. He achieved a grip strength of 52kg in his dominant hand and reported minimal pain throughout the entire process.
Whilst the hook plate is not a new technique for hand-based avulsion injuries, suffering sequential bilateral FDP avulsions within seconds of each other was something not seen in the literature. The authors believe simple non comminated FDP avulsions can be treated successfully with simple hook plating alone and further fixation is not required.
