Heterotopic Ossification of the Elbow after Medial Epicondylectomy

Postoperative heterotopic ossification of the elbow after surgery for treatment of acute trauma such as fractures and ligament/tendon ruptures has been well-documented. However, literature concerning heterotopic ossification after medial epicondylectomy is scarce. We report on two cases of heterotopic ossification that occurred following medial epicondylectomy for medial epicondylitis and for cubital tunnel syndrome. Preoperatively, calcifications around the medial epicondyle were observed in both patients. These cases suggest that medial epicondylectomy, in the presence of pre-existing calcifications, may pose an increased risk of postoperative heterotopic ossification of the elbow.
