Overuse injuries are responsible for many of the nontraumatic elbow injuries seen in young athletes. One of these overuse injuries is called osteochondritis dissecans (OCD) of the elbow or capitellum. The capitellum is a small head or rounded part of the elbow on the inside of the arm, closest to the body. Many of these injuries can be treated with rest and activity modification. However, when non-surgical treatments fail, or if the athlete is experiencing unstable lesions (tears,) loose bodies, or persistent mechanical symptoms, arthroscopic treatment of osteochondritis dissecans may be necessary. Dr. James Mazzara, elbow surgeon serving Manchester, South Windsor, Enfield, Glastonbury and surrounding Hartford communities has extensive experience with arthroscopic treatment of osteochondritis dissecans of the elbow.
