OCDs of the elbow

In this video, Dr. Grant H. Garcia focuses on the diagnosis and treatment of osteochondritis dissecans (OCDs) of the elbow, a joint condition where a piece of cartilage and underlying bone loses blood supply.

Here is a summary of the core medical insights he shares:

• At-Risk Patient Demographics: OCD lesions of the elbow are most commonly seen in young, active populations who subject their joints to high, repetitive impact forces. This includes youth baseball players and gymnasts.
• The Nature of the Lesion: The injury typically presents as a small piece of cartilage and bone that either completely breaks off into the joint or forms a loose flap, causing localized pain and mechanical catching.
• The First Lines of Surgical Repair: When non-surgical management fails to provide relief, surgery is tailored to the state of the cartilage tissue:
  • Preserving the Fragment: If the loose piece is still relatively healthy and hanging on, the surgeon can drill micro-holes to stimulate healing and secure it back down using bio-absorbable screws that naturally dissolve over time.
  • Microfracture (Drilling): If the fragment is entirely falling apart and has to be removed, the surgeon can clean the area and drill into the bone to recruit marrow cells. While this drilling technique is less commonly favored in the knee, Dr. Garcia notes it remains highly effective in the elbow for encouraging new fibrocartilage to grow back over the gap.
• Advanced Reconstructive Options: If simpler repair methods are ineffective, a larger procedure known as an osteochondral transplant is required to replace the damaged area. To do this, surgeons can transfer a plug of healthy bone and cartilage taken from the patient's own knee, or use a cadaver donor graft (an osteochondral allograft). Dr. Garcia explains that he leans toward using donor allografts for these young athletes because it eliminates donor-site pain and morbidity in the knee while delivering equally excellent long-term results.
