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.
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.
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.
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.
指骨小骨碎片的固定通常很困难。在本研究中，对使用微型钩板进行手术治疗后的患者进行了临床和影像学评估。
2003年至2006年间，共有36例骨折采用微型钩板进行手术治疗。其中24例患者为远节指骨基底撕脱骨折，11例患者（12处骨折）为指骨其他骨撕脱骨折。对患者进行了临床、影像学评估，并使用上肢、肩部和手部功能障碍（DASH）问卷进行评估。
共检查了29例患者的30处骨折。平均随访时间为13.6个月。患指关节的平均活动范围为60.3°，平均DASH评分为2.8分。术后观察到5例指甲生长缺陷、1例感染和1例植入物继发性脱位。
使用微型钩板，可以保留关节并实现稳定的内固定而无需临时关节固定术；然而，前提是外科医生具备困难手术技术的经验和技能。
