摘要目的 探讨显微修复手指戒指撕脱性损伤的方法与疗效.方法 2009年3月至2014年12月,急诊收治手指戒指撕脱性损伤患者6例6指,其中男4例,女2例;年龄18～30岁,平均22岁;环指4例,中指2例,损伤平面均在掌指横纹,伴有指骨间关节骨折脱位的予复位固定,修复损伤韧带及掌板、伸肌腱,吻合动、静脉,缝合指神经,术后系统康复锻炼.结果 6指全部成活,随访8～30个月,手指外形良好,近侧指骨间关节主动活动范围70°～100°,平均80°,远侧指骨间关节主动活动范围40°～60°,平均50°,感觉恢复至S3～S3+,指腹两点辨别觉为5～12 mm.按中华医学会手外科学会断指再植功能评定试用标准评定:优4指,良2指.结论 通过显微外科技术修复手指戒指撕脱性损伤,术后系统康复锻炼,疗效满意.

abstractsObjective To investigate the clinical effect of microsurgical repair after ring avulsion injuries. Methods From March, 2009 to December, 2014, 6 cases (6 fingers) of ring avulsion injury were repaired. There were 4 males and 2 females with an age range of 18-30 (mean, 22) years, which were 4 cases of ring finger and 2 cas-es of middle finger. The plane of injury was metacarpophalangeal band. Fracture and dislocation was reduced and fixed if damage fingers following with fracture and dislocation of interphalangeae.The damage ligament and volar plate and extensor tendon was repaired. The digital arteries and veins were repaired, and the digital nerves were sutured. System rehabilitation exercise carried out postoperatively. Results All fingers survived, and were followed-up for 8 to 30 months. The appearance of the fingers was excellent. The avarege range of motion of the proximal interpha-langeal was 80°(ranged from 70°to 100°).The distal interphalangeal was 50°(ranged from 40°to 60°).The sensory re-covery of finger pulp ranged from S3to S3+.The two-point discrimination was 5 mm to 12 mm. According to the Eval-uation Criteria for Finger Replantation and Reconstruction Issued by Chinese Hand Surgery of Chinese Mdical Associ-ation, 4 fingers had excellent while 2 had fairly good function. Conclusion Microsurgical repair of ring avulsion injury can achieve satisfactory clinical results by rehabilitation exercises postoperatively.
