Functional outcome after surgical treatment of phalangeal fractures in severely injured hands

We assessed functional results after treatment of phalangeal fractures in severely injured hands. Our aim was to quantify digital functional loss with (combinations of) risk factors of unsatisfactory function. Patients who had multiple phalangeal fractures necessitating operation in a 10-year time period were tested, using measurements of total active movement. Seventy-eight patients with 228 phalangeal fractures were available for follow-up. In 88 fingers, the fractures ended in amputation and were excluded from the study. In the resulting 140 fractures, 74 (53%) had a good result (movement >18° for fingers 2-5, and >98° for the thumb), and 66 (47%) in an unsatisfactory result. Associated soft tissue injury, level of injury, and arthrodesis were risk factors for diminished function. Intra-articular fractures and multiple fractures within the same finger predisposed to arthrodesis. Despite the extensive and severe injuries more than half had good results, which is comparable with reports describing hand injuries with less extensive trauma.
