Abstract:

Objective

To define the benefit of arthroscopic release of the anterior glenohumeral joint in frozen shoulder.

Methods

Sixty idiopathic adhesive capsulitis (IAC) patients were diagnosed by magnetic resonance imaging or intraoperative arthroscopic findings in Shaanxi Provincial People’s Hospital from March 2015 to March 2017. The exclusion criteria included fractures, subacromial impingement, rotator cuff tear and calcifying tendinitis. All the patients underwent arthroscopic capsular release. The extent of release focused on the rotator interval, subscapularis tendon and inferior glenohumeral ligaments (IGHL). Visual analogue scale (VAS), Constant functional scores, the Fudan University shoulder score (FUSS) and the range of motion (ROM) in various directions were recorded preoperatively and postoperatively. Statistical analysis was performed with one-way repeated measures ANOVA and paired t-test.

Results

None of the patients had postoperative complication such as axillary nerve injury or shoulder instability. At 12 weeks postoperatively, both of VAS [(0.7±0.6)vs(8.1±0.7), F =38.01], Constant score [(93.9±3.0)vs (34.2±3.4), F=121.42]and FUSS [(93.8±1.3)vs (40.1±2.2), F=220.09] increased significantly compared with the preoperative ones(all P<0.01). ROM showed satisfactory results at the final follow-up: abduction [(152±13)° vs (74±9)°, t=37.678], flexion[(156±12)° vs (60±10)°, t=46.469], external rotation at 90° of abduction[(66±11)° vs (8±3)°, t=37.762], internal rotation at 0°of abduction, and internal rotation at 90° of abduction recovered 12 weeks after the surgery(all P<0.01).

Conclusion

The arthroscopic release of the anterior glenohumeral joint may significantly improveboth of the function and ROM in IAC patients.
