Abstract
Bioabsorbable implants are very frequently used to treat rotator cuff and shoulder labrum injuries. Many researchers have observed small areas of osteolysis after treating pathological conditions of the shoulder using bioabsorbable anchors. Biological and mechanical theories have been put forward to account for the osteolysis caused by these materials. The case of a patient who was simultaneously treated for a rotator cuff lesion using the double-row technique and a Bankart lesion using bioabsorbable PLLA anchors and Fiber Wire®, and developed extensive osteolysis of the anatomical neck of the humerus, is described. Given that an anchor was used in the glenoid, and this did not present osteolysis, the hypothesis that mechanical factors are important in the etiology of this complication is raised.
