slipped capital femoral epiphysis occurs when the upper end of the thigh bone
(femur) slips at the area where the bone is growing (growth plate or physis)
and does not fit in the hip socket correctly. The condition is most common in
young teenagers. It's more common in boys than in girls.
What causes a slipped capital femoral epiphysis?
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.
What are the symptoms?
Symptoms usually begin
between ages 10 and 16 years. They may begin earlier in girls than in boys.
Symptoms vary in severity and speed of progression. Symptoms may
Hip tenderness or pain and decreased movement
during the early stages of the condition.
Increased pain when the
toes are turned in toward midline (internal rotation of the
Mild discomfort in the groin, thigh, or knee while walking or
running. Rest relieves this discomfort.
Knee pain. Sometimes knee
pain is the first symptom.
Stiffness and a limp, especially when
Mild to severe pain.
How is a slipped capital femoral epiphysis diagnosed?
Your doctor will conduct a medical history to learn how long
you have had your symptoms and a physical exam to identify your symptoms.
X-rays and sometimes
CT scan or
MRI are used to confirm a diagnosis of slipped capital
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 with pins. Osteotomy may be used in a severe case, but this is rare. In an
osteotomy, the doctor cuts the bone at the top of the leg near the hip joint,
moves the bone to a more normal position, then uses metal pins to hold it in
place. The pins are usually left in the bone after it heals.
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.
A slipped capital femoral epiphysis may lead to early degenerative
arthritis of the hip if it is not detected early and treated properly.
Who is affected by a slipped capital femoral epiphysis?
A slipped capital femoral epiphysis is the most common serious hip
condition seen in teenagers. It is more common in boys than in girls and more common
in very overweight teenagers. The condition most commonly affects young
adolescents, ages 10 to 16 years.
