Arthroscopic Thermal Capsulorrhaphy as Treatment for the Unstable Paralytic Shoulder

Abstract

Patients who present with global capsular laxity and glenohumeral instability frequently can be treated successfully with shoulder girdle musculature strengthening exercises and activity modification. When such injury is caused by a paralytic shoulder, a rehabilitation program may not be a viable treatment option. Presented in this article are 3 patients with global capsular laxity and glenohumeral instability as a result of shoulder paralysis. We also describe an arthroscopic technique of thermal capsulorrhaphy. In our experience, arthroscopic thermal capsulorrhaphy used to treat global capsular laxity and glenohumeral instability resulting from a paralytic shoulder has decreased symptoms of shoulder instability and has significantly reduced shoulder pain.
