T1 Glenohumeral Chondrolysis Associated with Use of an Intra-Articular Pain Pump Delivering Local Anesthetics Following Manipulation Under AnesthesiaA Report of Four Cases JF The Journal of Bone & Joint Surgery JO The Journal of Bone & Joint Surgery YR 2011 FD September 7 VO 93 IS 17 SP e99 1 OP 8 DO 10.2106/JBJS.J.01604 UL http://dx.doi.org/10.2106/JBJS.J.01604 AB Glenohumeral chondrolysis is a devastating condition characterized by rapid dissolution of the articular cartilage surfaces of the glenoid and the humeral head. Patients typically present with a painful stiff joint, and radiographs demonstrate joint space narrowing and subchondral cystic changes. Because most cases of glenohumeral chondrolysis have occurred following arthroscopic shoulder surgery, the term "post-arthroscopic glenohumeral chondrolysis" (PAGCL) has been used to describe this condition. Several causative factors have been implicated, including suture anchors that are prominent or that become loose1, excessive intra-articular use of thermal heat2-4, and intra-articular pain pump (IAPP) catheters delivering local anesthetics5-10. Most of the patients described developed glenohumeral chondrolysis following arthroscopic stabilization procedures in which one or more suture anchors were employed, with or without adjunctive use of thermal heat, and in which an IAPP was placed at the conclusion of the procedure to deliver local anesthetics for postoperative analgesia.
