What is a slipped capital femoral epiphysis?

A slipped capital femoral epiphysis occurs when the upper end of the thigh bone slips at the area where the bone is growing (growth plate or physis) and does not fit in the hip socket properly. The condition is most common in young teenagers and is more common in boys than in girls.

What causes it?

Rapid growth and an imbalance of hormones during adolescence may cause a slipped capital femoral epiphysis. An injury or a rapid increase in body weight or height may trigger symptoms. It is the most common serious hip condition in teenagers and is more common in teenagers with excess weight.

What are the symptoms?

Symptoms usually begin between ages 10 and 16, and may start earlier in girls than boys. Symptoms vary in severity and speed of progression. They may include:

  • Knee pain, which may be the first symptom
  • Hip tenderness or pain and decreased movement during the early stages of the condition
  • Increased pain when the toes are turned in toward the midline (internal rotation of the hip)
  • Mild discomfort in the groin, thigh or knee while walking or running, which can be relieved with rest
  • Stiffness and a limp, especially when tired
  • Muscle spasms

How is it diagnosed?

Your doctor will conduct a medical history to learn how long your child has had symptoms and a physical exam to identify their symptoms. X-rays and, on occasion, CT scans or MRI are used to confirm a diagnosis of slipped capital femoral epiphysis.

How is it treated?

The goal of treatment for a slipped capital femoral epiphysis is to prevent further slippage, restore the normal position of the bones and reduce complications of the condition. This often involves surgery to secure the growth plate (physis) with a single screw or pins.

Crutches may be used to take weight off the hip. Before surgery, this prevents further slippage and helps reduce pain. After surgery, using crutches reduces pain and helps keep the hip stable and in good position as it heals.

Osteotomy (surgical cutting of the bone) may be used in a severe case, but this is rare.

A slipped capital femoral epiphysis may lead to early degenerative arthritis of the hip if it is not detected early and treated properly.
