Background: Fixation of the small bony fragments of the phalanges is often difficult. In this study a clinical and radiological evaluation was carried out after operative treatment using the mini-hook plate.
Patients and methods: Between 2003 and 2006 a total of 36 fractures were treated operatively using the mini-hook plate. Of the patients 24 had an basal avulsion fracture of the distal phalanx and 11 patients (12 fractures) had other bony avulsion fractures of the phalanges. The patients were evaluated clinically and radiologically as well as using the disabilities of the arm, shoulder and hand (DASH) questionnaire.
Results: A total of 29 patients with 30 fractures were examined. The mean follow-up was 13.6 months. The mean range of motion in the affected finger joint was 60.3 ° and the mean DASH score was 2.8 points. Postoperatively five nail growth defects, one infection and one secondary dislocation of the implant were observed.
Conclusion: Using the mini-hook plate, preservation of the joint and stable internal fixation with no need for temporary arthrodesis is possible; however, prerequisites are experience and skill of the surgeon with a difficult surgical technique.
