17485 Slipped Capital Femoral Epiphysis Scfe

Overview

Slipped capital femoral epiphysis (SCFE) is a hip problem that happens in growing children and teenagers. The "ball" at the top of the thigh bone slips off the growth plate, like a scoop of ice cream slipping off a cone. This can cause pain and make it hard to walk.

SCFE is the most common hip disorder in teenagers, but it is still relatively rare. It affects about 1 in 10,000 young people.

It most often affects boys between ages 12 and 15, especially during rapid growth. Teenagers who are overweight are at higher risk, and it can affect one or both hips.

Symptoms

Common symptoms

• Pain in the hip, groin, thigh, or knee
• Limping or walking with the foot turned outward
• Stiffness or reduced range of motion in the hip
• Difficulty putting weight on the affected leg
• Pain that gets worse with activity

Symptoms in children

• A sudden limp without a clear injury
• Complaining of knee pain, even though the hip is the problem
• Trouble sitting cross-legged or doing hip movements
• Walking with the leg turned outward

Symptoms in older adults

• SCFE itself does not affect older adults. However, if it was untreated in youth, it can later lead to hip arthritis, which causes pain and stiffness in the hip or groin.

Causes

Main causes

• The exact cause is not fully known, but it involves a weakened growth plate at the top of the thigh bone.
• During a rapid growth spurt, the growth plate is more fragile and can slip.
• Excess body weight increases the stress on the growth plate.

Risk factors

• Being overweight or obese
• Being male
• Being in an adolescent growth spurt
• Having a family history of SCFE
• Hormonal conditions, such as underactive thyroid, that can weaken the growth plate

When to see a doctor

See a doctor urgently if:

• Sudden pain that stops you from walking
• Severe hip or knee pain after an injury
• A leg that suddenly looks twisted or shorter

Book a routine appointment if:

• Pain in the hip, groin, or knee that does not go away within a few days
• A limp that is new or getting worse
• Trouble moving the hip or putting weight on the leg

Diagnosis

A healthcare provider will ask about symptoms and examine the hip, checking movement and strength. They will often order an X-ray to look at the position of the thigh bone.

Tests that may be done

• A physical exam to see how the hip moves and whether there is pain
• An X-ray of the hip, which can show the slip
• Sometimes an ultrasound or MRI if the X-ray is unclear

What to expect at your appointment

The appointment may feel quick. You will be asked to lie down, stand, and move the leg in several directions. The X-ray is painless and takes only a few minutes. If SCFE is found, you will likely be referred to a bone specialist (orthopedic doctor).

Treatment

The main goal of treatment is to stop the thigh bone from slipping further and to reduce the risk of damage to the hip. Surgery is the standard treatment for nearly all cases of SCFE.

Self-care at home

• Do not put weight on the affected leg until your doctor says it is safe
• Use crutches or a wheelchair if providers recommend them
• Rest and avoid sports or rough activities
• Take only pain relief medicines that your doctor or pharmacist recommends for your age

Medical treatments

Treatment usually involves a minor surgical procedure where the doctor places small pins or screws into the hip to hold the thigh bone in place. This is done under general anesthesia, so the patient sleeps and feels no pain. In some situations, the doctor may do a procedure on the other hip as a precaution.

When is surgery considered?

Surgery is almost always needed for SCFE. It gives the best chance of preventing further slip and preserving the hip for the future. The exact type of surgery depends on how severe the slip is and the patient's growth stage.

Living with this condition

After treatment, most young people need to use crutches for a few weeks to allow the hip to heal. Physiotherapy exercises help regain strength and movement. Follow-up visits with the doctor check that the hip is healing well and that the screws stay in place.

Lifestyle tips

• Keep up with physiotherapy exercises as recommended
• Avoid running, jumping, and contact sports until the doctor gives the all-clear
• Try low-impact activities like swimming or cycling once your doctor allows
• Maintain a healthy weight to reduce stress on the hip

Diet and exercise

Eating a balanced diet that includes plenty of calcium and vitamin D supports bone health. Good sources are dairy products, leafy green vegetables, and fortified cereals. Gentle exercise, such as swimming or stationary biking, can help rebuild strength after recovery without jarring the hip.

Mental health and emotional wellbeing

Recovery from SCFE can feel long and frustrating, especially for teenagers who want to stay active. It is normal to feel sad, anxious, or stressed. Talking with family, friends, or a school counselor can provide emotional support and practical help during recovery.

Prevention

SCFE cannot always be prevented because it often happens during normal growth spurts. However, maintaining a healthy weight and treating any underlying hormone conditions may reduce the risk. If a teenager has a medical condition that weakens the growth plate, regular check-ups can help catch problems early.

Complications

If left untreated

• The thigh bone can continue to slip, causing more pain and disability
• The blood supply to the hip joint can be interrupted, which can damage the bone (a condition called avascular necrosis)
• Repeat slips can cause uneven leg length and a permanent limp
• Early hip arthritis may develop, leading to pain and stiffness in adulthood

Long-term outlook

With early diagnosis and proper treatment, the outlook for SCFE is very good. Most young people return to full, active lives without long-term problems. The key is to get medical help early and follow the doctor's advice during recovery.
