Objective 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.
