Slipped Capital Femoral Epiphysis

What is Slipped Capital Femoral Epiphysis?

Slipped capital femoral epiphysis (SCFE) is a condition of the hip joint that affects children. In SCFE, the head, or "ball," of the thigh bone (referred to as the femoral head) slips off the neck of the thigh bone. An analogy commonly used to describe this condition is that it can be like a scoop of ice cream slipping off the top of a cone. (The image to the left represents this.) This condition causes the hip joint to become painful and stiff.

Approximately one half of SCFE cases affect both hips, and boys are affected more often than girls. It can result from trauma, also referred to as an "acute slip," or can occur over a period of weeks to years. This is called a "chronic slip."

SCFE has three degrees of severity:

  • Mild--Approximately one-third of the femoral head slips off of the thigh bone (see A).
  • Moderate--Approximately one-third to one-half of the femoral head slips off of the thigh bone (see B).
  • Severe--More than one-half of the femoral head slips off of the thigh bone (see C).

What causes Slipped Capital Femoral Epiphysis?

The cause of SCFE is unknown. Risk factors that increase the likelihood of SCFE include:

  • Obesity
  • Medications (such as steroids)
  • Thyroid problems
  • Radiation treatment
  • Chemotherapy
  • Bone problems related to kidney disease

Who is affected by Slipped Capital Femoral Epiphysis?

SCFE is an unusual condition, which is more likely to occur in boys than girls. Children ages 11 to 15 are most at risk.

SCFE is more prevalent in the Northeast region of the United States than in the Southwestern states. It is also more prevalent among African-Americans.

Symptoms and Treatments

What are the symptoms of Slipped Capital Femoral Epiphysis?

Symptoms of SCFE typically include pain in the hip that is aggravated by activity. Sometimes the adolescent will also experience pain in the groin, thigh or knee area.

In acute slips, the adolescent will complain of immediate pain, limp or feel like the "leg is giving way."

The adolescent with a chronic slip usually walks with a limp, complains of hip pain and reports that rest alleviates the pain. The adolescent may walk with his leg turned outward and may also have a click in the hip.

The symptoms of SCFE may resemble other conditions or medical problems of the hip. Always consult your adolescent's physician for a diagnosis.

How is Slipped Capital Femoral Epiphysis diagnosed?

In addition to a complete medical history and physical examination, diagnostic procedures for SCFE may include:

  • X-ray--A diagnostic test that uses invisible electromagnetic energy beams to produce images of internal tissues, bones and organs onto film.
  • Bone scans--A nuclear imaging method to evaluate any degenerative and/or arthritic changes in the joints; to detect bone diseases and tumors; to determine the cause of bone pain or inflammation.
  • Magnetic resonance imaging (MRI)--A diagnostic procedure that uses a combination of large magnets, radiofrequencies and a computer to produce detailed images of organs and structures within the body.
  • Blood tests

The ultimate goal in SCFE is to diagnose the condition early in order to prevent the head of the femur from slipping further off of the thigh bone, thus preventing hip deformity. When the diagnosis of SCFE is made, the adolescent is not allowed to bear weight on the hip. Crutches or a wheelchair may be used.

Treatment of Slipped Capital Femoral Epiphysis

Your adolescent's doctor will determine the specific treatment for SCFE based on:

  • Your adolescent's age, overall health and medical history
  • The extent of the condition
  • Your adolescent's tolerance for specific medications, procedures or therapies
  • Expectations for the course of the condition
  • Your opinion or preference

The goal of treatment is to prevent the femoral head from further slippage. Treatment usually may include:

  • Surgery (involving the use of a steel pin to hold the femoral head onto the femur to prevent further slipping)
  • Physical therapy (following surgery, to help strengthen the hip and leg muscles)

What are X-rays?

X-rays are made by using low levels of external radiation to produce images of the body, the organs, and other internal structures for diagnostic purposes. X-rays pass through body structures onto specially treated plates (similar to camera film) and a negative-type picture is made. The more solid a structure is, the whiter it appears on the film. For this reason, bones appear very white on an X-ray film, but less dense tissue such as muscle, blood, skin and fat appears darker. An X-ray provides a picture of inside the body by using special radioactive rays. An X-ray can show bones, tissues or parts of organs.
