Index radial collateral ligament repair with titanium mini-suture anchor: osteolysis complication of an underreported injury.

We are reporting on a case of an index radial collateral ligament tear repaired with a titanium Mitek bone suture anchor. The development of cystic radiographic changes and increased pain and weakness led to suture anchor removal at 10 months post-repair. Periprosthetic osteolysis due to titanium-induced osteoclastogenesis and micromotion was suspected to be the cause. This case report provides a dual focus by stressing the importance of the diagnosis and treatment of this underreported ligament tear and highlighting our osteolysis complication via the mechanism of titanium-induced osteoclastogenesis for future therapeutic preventive measures.
