Endoscopic Management of Shoulder Pain in Long-Term Haemodialysis Patients

In 48 shoulders of 29 patients receiving long-term haemodialysis and complaining of intolerable shoulder pain, endoscopic resection of the coracoacromial ligament was performed under local anaesthesia on an outpatient basis, using the Universal Subcutaneous Endoscope system. Predominant endoscopic findings were proliferation of the subacromial bursae and popping between the coracoacromial ligament and the rotator cuff. Amyloid originating from beta 2 microglobulin (beta 2-M) was demonstrated in 87% of the resected coracoacromial ligaments and 86% of the subacromial bursae. Resection of the coracoacromial ligament relieved the shoulder pain in all patients.
