Abstract: BACKGROUND: Although arthroscopically assisted Latarjet procedure is the “gold standard” for the treatment of recurrent anterior dislocation of shoulder with obvious glenoid bone defect, it has high complications such as shoulder joint degeneration and progression. The clinical effect of the arthroscopically modified elastic fixation Latarjet procedure  has been good in recent years, but most of them are case reports. Modified elastic fixation Latarjet procedure  in the treatment of recurrent anterior dislocation of shoulder with obvious glenoid bone defect is necessary to be further evaluated.  
OBJECTIVE: To investigate the short-term clinical effect of modified elastic fixation Latarjet procedure  in the treatment of recurrent anterior dislocation of shoulder with glenoid bone defect.
METHODS: Totally 42 patients with recurrent anterior dislocation of shoulder with obvious glenoid bone defect diagnosed and treated in Affiliated Hospital of Zunyi Medical University from January 2017 to October 2019 were collected into our study. They were treated with modified elastic fixation Latarjet procedure. Visual analogue scale score, university of California at Los Angeles shoulder rating scale, American shoulder and elbow surgeons, Rowe score and Walsh-Duplay score were compared before and after surgery. Postoperative CT and 3D reconstruction of shoulder joint and plain radiograph of shoulder joint were performed to evaluate the position of bone fragments, the degree of correction of glenoid defect, the degeneration of shoulder joint, and the healing and absorption of transposition coracoid process.  
RESULTS AND CONCLUSION: (1) The operation process of 42 patients was successful, and there were no serious complications such as nerve or vascular injury after operation. All patients completed the follow-up of 20-34 months. (2) The visual analogue scale score, university of California at Los Angeles shoulder rating scale score, American shoulder and elbow surgeons score, Rowe score, Walsh-Duplay score were significantly improved at 10 days after surgery compared with before operation, and no dislocation or subluxation occurred again in all patients. (3) At the last follow-up, all patients underwent shoulder CT, which showed that the shoulder glenoid reached the normal level, without transposition, coracoid process absorption or bone nonunion. (4) The modified elastic fixation Latarjet procedure  can obtain satisfactory clinical effect in the treatment of recurrent anterior dislocation of shoulder with obvious glenoid bone defect. The operation time is short, with minimally invasive and fine arthroscopic operation. The position of coracoid process is satisfactory. There is no recurrent dislocation or subluxation after operation. It can significantly improve the function of shoulder joint.
