Background:
Manipulation under anesthesia (MUA) of the shoulder joint is a commonly used method for the treatment of adhesive capsulitis. Though it has been known to be associated with a variety of complications, there is a paucity of studies describing the arthroscopic findings after MUA.
Aim:
To describe the arthroscopic findings in patients with idiopathic adhesive capsulitis of the shoulder after MUA.
Methods:
We recruited 28 patients with idiopathic adhesive capsulitis who underwent arthroscopic capsular release. Manipulation of the shoulder was performed under anesthesia in all of these patients before capsular release. Intra-articular findings were recorded during arthroscopic capsular release in these patients.
Results:
All patients showed the presence of synovitis. Twenty-seven patients showed tears in the capsule on the anterior aspect. One patient had an avulsion of the anterior rim of the glenoid and labrum following the manipulation. Four patients had partial rotator cuff tears, and one patient showed a superior labrum anterior posterior lesion, which was not diagnosed preoperatively on magnetic resonance imaging.
Conclusion:
MUA leads to rupture of the capsule, which is the desired outcome. However, the site of rupture of the capsule is dependent on the maneuvers of MUA. In addition, partial tears of the rotator cuff and osteochondral fractures of the glenoid can also occur.
Insights
Manipulation under anesthesia (MUA) for shoulder adhesive capsulitis causes capsule tears, as seen arthroscopically. Potential complications include rotator cuff tears and glenoid rim avulsion, highlighting the need for careful MUA technique.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Arthroscopy
Background:
- Manipulation under anesthesia (MUA) is a common treatment for shoulder adhesive capsulitis.
- Limited arthroscopic data exists on MUA complications.
Purpose of the Study:
- To detail arthroscopic findings following MUA in idiopathic adhesive capsulitis patients.
Main Methods:
- 28 patients with adhesive capsulitis underwent MUA followed by arthroscopic capsular release.
- Intra-articular findings were documented during surgery.
Main Results:
- All patients exhibited synovitis.
- Anterior capsule tears were observed in 27 patients.
- One patient had an anterior glenoid rim and labrum avulsion; four had partial rotator cuff tears.
Conclusions:
- MUA effectively ruptures the capsule, but tear location varies with technique.
- Associated injuries include rotator cuff tears and glenoid osteochondral fractures.
