Hip impingement (femoral acetabular impingement) develops from abnormal contact between the top of the thigh bone (femoral head) and the outside of the hip socket (acetabulum). The abnormal contact, typically caused by bony deformities, leads to friction that wears away cartilage and the joint’s fibrous seal (labrum).
Types of Hip Impingement
Patients who have hip impingement have one or a combination of the following deformities of the hip joint.
- Cam impingement: Cam impingement is caused by a deformity of the ball at the top of the thigh bone (femoral head). The abnormally shaped part of the ball comes into direct contact with the hip socket (acetabulum) with certain hip movement.
- Pincer impingement: Pincer impingement is a deformity of the acetabulum. It occurs when the rim of the acetabulum comes in direct contact with the femoral head because the acetabulum is either too deep or in an abnormal position.
- Mixed impingement: A combination of cam and pincer deformities.
Hip Impingement Symptoms and Effects
Patients who have hip impingement might experience the following symptoms:
• Hip, thigh or groin discomfort
• Inflexibility or stiffness of the hip joint
• Pain in the hip, groin or lower back that occurs during activity or when the hip is flexed
• A clicking, locking or snapping sensation in the hip joint
Symptoms of hip impingement often develop during adolescence and gradually become more noticeable with age. If left untreated, the condition can lead to osteoarthritis of the hip.
Hip Impingement Incidence, Causes and Risk Factors
The exact cause of hip impingement is unknown. In some cases, participation in rigorous physical activities can lead to hip impingement. In addition, conditions such as Legg-Calvé-Perthes disease and slipped capital femoral epiphysis (SCFE) can cause changes or deformities to the hip joint, leading to hip impingement.
Hip Impingement Tests and Treatment
At Gillette, our goal is to diagnose and treat hip impingement as soon as possible to prevent additional damage to the hip joint. Our specialists diagnose hip impingement using a combination of tests, including a physical examination and a review of the patient’s medical history.
Tests used to diagnose hip impingement might also include:
- X-ray: to show irregularities in the hip joint
- CT scan or MRI: to provide a more detailed view of the upper femur and acetabulum and display the amount of cartilage damage.
Treatments for hip impingement might include the following.
We might prescribe anti-inflammatory or pain-relieving medication. In some cases, patients might benefit from an intra-articular injection containing an anti-inflammatory steroid medication.
We might recommend physical therapy to stretch joints and strengthen muscles, which helps improve mobility and range of motion.
Sometimes we’ll suggest modifying a child’s activities to prevent further damage to the hip joint.
If the above treatments aren’t effective, surgery sometimes is needed. Specialists might perform arthroscopic or open surgery, depending on the type of hip impingement and the severity of the damage to cartilage.
