Osteochondritis dissecans (OCD) of the elbow is a focal disruption of the subchondral bone with overlying cartilage, most commonly affecting the capitellum (the lateral side of the humerus at the elbow) in skeletally immature throwing athletes and gymnasts. Early recognition and treatment preserve cartilage and prevent progression to displaced fragments and post-traumatic arthritis.
What Is Elbow OCD?
OCD is a condition in which a segment of subchondral bone loses its blood supply, softens, and can separate from surrounding bone. The overlying cartilage may remain intact or may detach with the bone fragment. In the elbow, OCD most commonly affects the capitellum.
OCD lesions are staged:
- Stable lesions: intact cartilage, no fragment separation
- Unstable lesions: partial separation with cartilage at risk
- Displaced lesions: full separation, often with a loose body in the joint
Early recognition matters. Stable lesions in skeletally immature patients often heal with rest and protected activity. Displaced lesions require surgery and have less predictable outcomes.
Causes and Risk Factors
- Repetitive valgus loading of the elbow (overhead throwing, gymnastics)
- Skeletal immaturity (most common in adolescents 11 to 17 years old)
- High pitch counts in baseball
- Repetitive weight-bearing on extended arms (gymnastics, weight-bearing sports)
- Possible genetic predisposition
- Most common in male athletes participating in throwing sports
Symptoms
- Vague lateral elbow pain with throwing or weight-bearing activity
- Catching, locking, or loss of motion if a fragment is unstable or displaced
- Loss of full elbow extension in some cases
- Effusion of the elbow with activity
- Pain at the lateral elbow on palpation
Diagnosis
Dr. Chudik’s evaluation includes the sport and activity pattern, the duration of symptoms, and a focused elbow examination. X-rays may show the lesion in established cases but can miss early disease. MRI is the imaging study of choice and characterizes lesion size, depth, stability, and the status of the overlying cartilage. The Westmont office has on-site high-field MRI and X-ray.
Treatment
Non-surgical treatment is the first line for stable lesions in skeletally immature patients. It involves:
- Rest from throwing or weight-bearing for three to six months
- A targeted physical therapy program for elbow mechanics and conditioning
- Serial imaging to monitor healing
- Gradual return to activity once imaging confirms healing
Surgical treatment is indicated for unstable or displaced lesions and for stable lesions that fail non-surgical treatment. Dr. Chudik performs arthroscopic procedures including debridement, microfracture, fragment fixation with bioabsorbable implants, osteochondral autograft transfer (OATS) for larger defects, and removal of loose bodies when fragments are not salvageable.
Recovery and Outcomes
Recovery with non-surgical treatment for stable lesions typically takes three to six months with gradual return to throwing or weight-bearing once imaging confirms healing.
Recovery after arthroscopic treatment depends on the specific procedure. Debridement allows return to activity within weeks. Microfracture and fragment fixation typically require six to eight weeks of protected loading and return to sport at four to six months. Osteochondral grafting has a longer recovery.
Outcomes are best when stable lesions are recognized and treated early in skeletally immature patients. Adult OCD and chronic displaced lesions have less predictable outcomes.
