Background: The aim of this study is to report the surgical procedures performed in patients with mutilating hand injuries and evaluate the outcomes of treatment.
Methods: A retrospective evaluation of 130 patients operated between 2000 and 2005 for mutilating hand injuries is presented. Twenty-five of the patients could be followed until the end of rehabilitation. The grip power and ranges of motion in affected joints were determined. Minnesota manipulation speed test and Purdue Pegboard Test were used for evaluation of functional results.
Results: Mean range of motion was 64.7% (minimum: 17%, maximum 96%) of the uninjured extremity. Mean grip strength was 52% (15-80%) of the uninjured extremity. Lateral pinch was 66% (25%-81%) of the contralateral hand and the results were 53% (12%-68%) for key pinch and 52% for tripod pinch. Minnesota manipulation speed test showed satisfactory results in 92% of the patients in hand skill, strength and coordination. A decrease in fine motor skills was observed in Purdue Pegboard Test.
Conclusion: The main treatment purposes in mutilating hand injuries are obtaining an extremity that is useful in daily activities and if possible that facilitates a return to work.
