Study Notes
Osteochondritis Dissecans (OCD)
- The exact cause of OCD is unknown, but repetitive trauma or stresses to the bone over time are probable contributing factors.
- Symptoms of OCD include pain and swelling of a joint, often triggered by sports or physical activity.
- Advanced cases of OCD can cause joint catching or locking.
- X-rays are essential for initial diagnosis and evaluating the size and location of the OCD lesion.
- Magnetic Resonance Imaging (MRI) is used to assess the extent of damage to the overlying cartilage.
- In most cases, OCD lesions in children and young teens will heal on their own with rest and avoidance of vigorous sports.
- Non-surgical treatment options include resting, avoiding sports, using crutches, splinting, or casting the affected limb for a short period.
- Most children start to feel better over a 2- to 4-month course of rest and non-surgical treatment.
Surgical Treatment
- Indications for surgery include:
- Failure of non-surgical treatment to relieve pain and swelling
- Separation or detachment of the lesion from the surrounding bone and cartilage
- Large lesions (greater than 1 centimeter in diameter), especially in older teens
- Surgical procedures include:
- Drilling into the lesion to create pathways for new blood vessels
- Internal fixation (using pins and screws) to hold the lesion in place
- Replacing the damaged area with a new piece of osteo-cartilagenous graft to regenerate healthy bone and cartilage
Slipped Upper Femoral Epiphysis
- The developing epiphysis of the hip partially slips, often in an overweight hypogonadal boy.
- Symptoms include hip pain or referred pain to the knee.
- Diagnosis may be difficult and delayed, but a 'frog lateral' X-ray can show the deformity.
- Trethowan's sign is positive in slipped femoral epiphysis.
