摘要目的 探讨微型钩钢板治疗急性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月我们对20例急性拇指近节指骨基底部尺侧撕脱骨折患者采用切开复位微型钩钢板固定,纠正骨折畸形,恢复侧副韧带止点解剖结构.结果 术后所有患者均获得随访,时间为6～24个月,平均16.2个月;骨折愈合时间为4～7周,平均5.2周.根据Saetta标准评定掌指关节功能:优14例,良5例,可1例.X线片显示撕脱骨折线消失.结论 微型钩钢板治疗急性拇指近节指骨基底部尺侧撕脱骨折能达到坚强内固定,术后第一掌指关节功能恢复满意,疗效可靠.

abstractsObjective 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.
