Hip Abductor Tendon Tears
Hip abductors are a major group of muscles found in the buttocks. It includes the gluteus maximus, gluteus medius, gluteus minimus, and tensor fascia lata muscles. The Gluteus medius arises at the top of the pelvic bone and attaches to the outer side of the greater trochanter on the femur. The muscle controls side-to-side movement of the hip and stabilizes hip movement. The most common hip abductor tear is the gluteus medius tendon. It is also referred to as rotator cuff tear of the hip.
The tear or rupture of the gluteus medius muscle is commonly seen in runners and athletes involved in high-impact sports such as soccer or basketball due to sudden bursts of activity or poor flexibility of the gluteus muscle. Any traumatic or overuse injury, or degenerative changes may lead to partial or complete tear of the gluteus muscle.
The symptoms include pain and tenderness over the lateral aspect of the hip which may aggravate with activities such as running, climbing stairs, prolonged sitting or walking, and lying on the affected side of the hip. One of the main symptoms of gluteus medius tear is the presence of Trendelenburg sign – dropping of the pelvis towards the unaffected side by being unable to bear weight on the affected limb.
The diagnosis of gluteus medius tear is based on physical examination of the patient, followed by palpation of the affected muscle, testing muscle power and assessing walking pattern or gait of the patient. Certain special tests such as single-leg squat test or a positive Trendelenburg sign confirm the diagnosis of gluteus medius tear. Sometimes, MRI or ultrasound may be helpful to show the pathological changes of the muscle.
The aim of treatment is to restore the normal function of the gluteus medius tendon. Immediately following the rupture of the tendon, RICE therapy is advised which involves:
- Rest your hip by refraining from activities until it is healed.
- Apply ice to your hip to reduce pain and inflammation caused by injury.
- Compression with an ACE bandage helps to reduce tenderness and swelling.
- Elevation involves keeping the affected hip raised above your heart to minimize swelling.
- Medications such as non-steroidal anti-inflammatory drugs (NSAIDs) or steroid injections may be given to reduce the pain and inflammation.
- Assistive devices such as a cane or crutch may be used temporarily to facilitate pain free ambulation
- Dr. Faucett may recommend physical therapy to strengthen the muscles and increase stability of the hip.
Surgical treatment may be recommended to repair a complete, full-thickness gluteus medius tear. The rupture can be repaired arthroscopically to help restore the strength and function of the gluteus medius.
Untreated cases of gluteus medius tear may result in gait disturbance and disability. This is called a Trendelenburg gait and causes the patient to lean their body over the hip since the muscle cannot stabilize the hip.
