Slipped Capital Femoral Epiphysis
This injury occurs when there is a fracture at the neck (top, below the ball shaped head) of the femur (thigh bone). The fracture usually occurs gradually over a period of time and the two parts of the bone then 'slip' apart, with the head of the Femur moving backwards.
Symptoms include:
- Hip pain and groin pain which can also radiate into the knee.
- A limp.
- A professional may find that the affected leg is shorter and often rotated externally (laterally).
- Moving the leg to the side (abduction) is often limited compared to the other side.
- Rotating the hip laterally is also limited.
The epiphysis is the area of the bone that does the growing in children and adolescents. This area is sometimes called the growth plates. It is often brought on by sports activity.
This is an uncommon condition which typically affects boys aged eleven to sixteen years old. It is more common in those who are considered overweight and may sometimes be present in both hips.
A slipped capital femoral epiphysis can cause problems with a decrease in blood flow to the head of the Femur, resulting in avascular necrosis (bone death) and so should be addressed as soon as possible.
Treatment
- Due to the potential for death of the femoral head, medical attention should be sought as early as possible.
- If this injury is suspected X-rays should be taken to confirm the diagnosis.
- If positive, orthopedic assessment is required and surgery may be performed.
- Surgery involves fixing the head of the femur with pins or a screw.
- After a period of immobilisation, a full rehabilitation prgramme is required to return to full weight bearing and then to regain full strength and movement in the hip.
