Pain on the outside of the hip is due to swelling of the tendons in the buttock. Often, this condition is called greater trochanteric pain syndrome. Sometimes, swelling of the gluteus medius tendon leads to tearing – either a partial or full tear, also known as gluteal tendon tear. How common are gluteal tendon tears, and how do we manage them?
The gluteus medius muscle lies under the large gluteus Maximus muscle, also known as the large buttock muscle. The muscle starts on the side of the large hip bone called the ileum. It narrows as it passes outward to attach to the knob of bone outside the femur called the greater trochanter. At the attachment, it forms a strong gluteus medius tendon. On top of the tendon is a bursa known as the trochanteric bursa.
Gluteal tendon tear symptoms
Generally, symptoms of a gluteal tendon tear are similar to gluteal tendinopathy or greater trochanteric pain syndrome. Most people have pain outside the hip, which is worse during walking, stairs, and lying on the hip. However, tears often have worse pain. Also, people describe weakness and a feeling of dragging the leg or not being able to support their body weight while walking.
How to make a diagnosis
Overall, we diagnose a gluteal tendon tear based on the description of pain on the outside of the hip.
Often, examining the person reveals weakness with moving the hip outside, also known as hip abduction.
Generally, we use imaging to diagnose a gluteal tendon tear compared to tendinopathy. However, studies suggest ultrasound and MRI can see a gluteal tendon tear.
Gluteal tendon tear MRI
Most doctors use MRI to confirm a diagnosis of a gluteal tendon tear. Generally, imaging shows a tear of the fibres of the tendon. If the tear is full thickness, imaging often shows the tendon pulled away from the bone, also called retraction. Also, a full-thickness tear can lead to wasting of the muscle, known as atrophy.
Gluteal tendon tear treatment
While gluteal tendon tears have a worse outlook than tendinopathy, only a minority need surgery. Like gluteal tendinopathy, we start with simple treatments such as exercise and move on to other treatments such as injections or surgery if required. Also, we think that partial tears are treated differently from full tears.
Can a gluteal tendon tear heal?
Generally, we don’t think that tendon tears heal. However, some treatments improve the structure of the tear so it can work better.
Like greater trochanteric pain syndrome, we think that exercise therapy helps people with partial or full-thickness tears. Generally, we suggest a combination of hip exercises such as side-lying hip raises, clam walks, hip bridges, and squats.
What is the role of shockwave?
We know that shockwave helps greater trochanteric pain syndrome. However, there is little evidence that shockwave therapy helps partial or full tendon tears.
PRP injection for a gluteal tendon tear
We know that a single leucocyte-rich PRP injection improves greater trochanteric pain syndrome. The researchers found that PRP can also improve pain related to partial tendon tear in the tendon of hip in the same study. However, we have no data on full tears. Overall, we think that PRP injections might work for partial tears.
However, we think you should avoid cortisone injections for a partial or full gluteal tendon tear.
What is the role of surgery?
Our evidence for surgery is limited. Generally, however, repairs are better in partial tears and those full tear cases with less muscle wasting. In addition, some surgeons are now doing repairs with keyhole surgery, reducing the recovery time. Overall, the repair failure rate ranges from 5 to 15%.
Usually, post-repair recovery consists of a partial weight-bearing with crutches for six weeks and then resistance training using hip exercises after three months. Overall, full recovery from a repair can take up to 6 months.
Final word from sportdoctorlondon about a tear in tendon of hip
Tears of the gluteal tendons cause pain with walking and other activities similar to tendonitis. We favour PRP injections and exercise for partial tears and early surgical repair for full tears.
