Abstract

Objective To evaluate the clinical outcomes of mini hook plate in the treatment of acute ulnar avulsion fracture at the base of proximal phalanx of thumb. Methods From February 2015 to February 2016, 20 cases of acute ulnar avulsion fracture at the base of proximal phalanx of thumb were treated by open reduction and mini hook plate fixation to correct the fracture deformity and reconstruct the collateral ligament attachment. Results All the patients were follow-up for 6 to 24 months with an average of 16.2 months. The time of fracture healing ranged from 4 to 7 weeks, averaging 5.2 weeks. According to Saetta functional assessment standard, the results were graded as excellent in 14 cases, good in 5 cases, and fair in 1 case. X-rays showed the line of avulsion fracture disappeared. Conclusion Application of mini hook plate in the treatment of acute ulnar avulsion fracture at the base of proximal phalanx of thumb can achieve strong fixation and lead to satisfactory postoperative function recovery of the first metacarpophalangeal joint. The clinical outcomes are reliable. Key words: Finger phalanges; Fracture fixation, internal; Metacarpophalangeal joint; Mini plate

微型钩钢板在拇指近节指骨基底部尺侧撕脱骨折治疗中的应用

目的评价微型钩钢板治疗拇指近节指骨基底部尺侧撕脱骨折的临床疗效。方法自2015年2月至2016年2月，对20例拇指近节指骨基底部急性尺侧撕脱骨折患者，采用切开复位微型钩钢板内固定术，矫正骨折畸形，重建副韧带附着体。结果所有患者随访6～24个月，平均16.2个月。骨折愈合时间4～7周，平均5.2周。根据Saetta功能评估标准，结果分为优14例，良5例，尚可1例。X光片显示撕脱骨折线消失。结论应用微型钩钢板治疗拇指近节指骨基底部尺侧撕脱骨折，可获得良好的固定效果，使第一掌指关节术后功能恢复良好。临床结果是可靠的。关键词：指骨；骨折内固定术；掌指骨关节；迷你平板
