Abstract: Objective：To retrospectively analyze the efficacy and safety of anterior elbow neurovascular gap approach in the treatment of ulnar coronoid process fractures.Methods：From January 1,2016 to March 1,2019,13 cases of ulnar coronoid process fracture were included.All patients were treated by the anterior brachial arterymedian neurovascular internervation approach.Results：All patients were followed up for 850 months(mean 29.1 months).All the fractures healed smoothly.The average healing time was 4.2 months(36 months).The range of motion of elbow joint was 10 ° to 20 ° with an average of（12.5±3.3）° and flexion of 120 ° to 140 ° with an average of （134.3±5.5）°.There was no significant difference with regard to pronation and supination compared to the healthy limb.According to the MEPS score at the last followup,the patient's score was 7098,with an average of  （92.5±7.3）.The elbow function was excellent in 5 cases,good in 7 cases and fair in 1 case.One patient had mild heterotopic ossification of elbow,which had no significant effect on elbow function.One patient had mild pain during elbow movement after operation,which could be relieved by topical analgesic drugs.Conclusion：The anterior neurovascular gap approach of elbow can be used safely and efficiently for the treatment of the fracture of ulna coronoid process under direct vision.
