ABSTRACT
Objective:
To investigate the clinical effect and safety of reduction and fixation for the anterior glenoid fracture through an axillary approach.Methods:
Two autopsy specimens (a total of 4 shoulder joints) were used to simulate the surgery of open reduction and internal fixation to treat anterior glenoid fracture through an axillary approach. Specimens were placed in the lateral decubitus position. An incision was made in the posterior axillary line to expose the lateral side of the scapula through the interval ahead of the latissimus dorsi muscle. Attended to the separation and protection of the axillary nerve, posterior humerus artery, thoracic dorsal nerve, and scapular artery. The surgical area of the axillary approach was divided into the upper "quadrilateral area" and the lower "trilateral area", which exposed the anteroinferior glenoid, neck, and the full length of lateral border of the scapula. Thirteen cases (7 males and 6 females) were involved in this study, all patients were diagnosed with anterior glenoid fracture and treated by open reduction and internal fixation through the axillary approach between April 2018 and December 2020. Constant-Murley score and Disabilities of the Arm, Shoulder and Hand (DASH) were used to evaluate the clinical efficacy.Results:
Thirteen patients were enrolled for final analysis, which included 12 right cases and 1 left case. The average age was 50.38±13.74 years (range 24-67 years). All 13 patients were classified as Ideberg type Ia fracture. Anatomical buttress plates were used in 5 cases, cannulated screws combined with metacarpal plates in 7 cases, and distal radius plate in 1 case. The average length of follow-up was 13.00±5.97 months (range 6-26 months). No delayed union or malunion in all cases at the last follow-up visits. The average of Constant-Murley score was 62.46±10.26 points (range 45-83) and the DASH score was 27.56±9.76 points (range 14.14-43.33) at the three months follow up visits. At 6 months postoperatively, the Constant-Murley score was 80.85±8.32 points (range 65 to 90) and the DASH score was 11.47±8.56 points (range 0 to 35.00). Constant-Murley score at the final patient's follow-up visit was 84.54±8.95 points (range 70-95), and the DASH score was 10.94±8.67 points (range 1.67 to 33.33 points). The joint function gradually recovered with time. The functional scores at 3 months, 6 months after surgery, and final follow-up visit had significant differences ( P<0.05).Conclusion:
The axillary approach is a safe and feasible approach for the treatment of the anterior glenoid fracture. This approach exposes the anteroinferior glenoid and the lateral border of the scapula, which reduces rotator-cuff injury and achieves anatomic reduction and strong fixation of the fracture. The axillary approach surgery also allows early functional physiotherapy after surgery.
