Gluteal Tendinosis and Trochanteric Bursitis

Gluteal tendinosis means the tendons of the gluteus medius or minimus, two buttock muscles that attach to the bony point on the outside of the hip, look thickened or changed on an ultrasound or MRI. Trochanteric bursitis means fluid or thickening in the small sac that lies over them. Both sit under greater trochanteric pain syndrome, and the tendons, rather than the bursa alone, are usually the main source of the pain. These findings are common in hips that do not hurt, so the report matters less than how the hip behaves at night, on stairs and on one leg.

Gluteal tendons at the hip

What “gluteal tendinosis” and “trochanteric bursitis” mean on a scan report

The tendons and the bursa. Two buttock muscles on the side of the hip, gluteus medius and gluteus minimus, keep the pelvis level each time you stand on one leg. Their tendons attach to the greater trochanter, the bony point you can feel on the outside of the hip. A thin fluid-filled sac, the trochanteric bursa, lies over them, under the iliotibial band (the thick band of tissue that runs down the outside of the thigh). An ultrasound or MRI report describes the tendons, the bursa and the bone where they meet.

The words that come with it. These are the terms you are most likely to see. Their definitions are not standardised, particularly for bursitis on ultrasound, so two reports can describe the same hip a little differently.

On the reportWhat it means
Gluteus medius, gluteus minimus, greater trochanterThe two buttock muscles on the side of the hip and the bony point their tendons attach to. Medius attaches to the side and the upper back of the bony point, minimus to its front (the lateral, superoposterior and anterior facets).
Tendinosis, tendinopathy, tendinitisThe tendon looks thickened, or its normal pattern has changed on ultrasound or its signal is brighter on MRI. Tendinosis describes that look, tendinopathy is the name for a painful tendon problem, and tendinitis is an older word some reports still use.
Peritrochanteric edema or fluid, peritendinitisBright fluid signal on MRI around the bony point, in or around the tendons and the bursa; peritendinitis means it sits around a tendon. In one study it was found in 88 percent of hips with no pain on the outside (Blankenbaker et al., 2008).
Trochanteric bursitis, bursal thickening, bursal fluid or distensionThe sac over the tendons looks thickened or holds more fluid than usual. Two smaller sacs, the subgluteus medius and subgluteus minimus bursae, sit under the tendons. In people with this pain, bursitis was less common on ultrasound than tendon changes (Long et al., 2013).
Partial-thickness, interstitial or undersurface tearA split through part of the tendon. Interstitial means inside the tendon; undersurface means on the side next to the bone. Partial tears are also found in hips without symptoms (Arvesen et al., 2022).
Full-thickness tear, retraction, avulsionThe tear goes all the way through the tendon. Retracted means the torn end has pulled back; avulsion means the tendon has come away from the bone. These are the findings most worth a surgical opinion, particularly with weakness or a limp.
Enthesopathy, cortical irregularity, enthesophyteChanges where the tendon attaches to the bone: a roughened bone surface or a small bony spur. They are read together with the tendon findings rather than as a separate problem.
Calcification, calcific tendinopathyCalcium deposits in the tendon near its attachment, which show on X-ray and ultrasound. Like the other findings, they are weighed against your symptoms and examination.
Thickened iliotibial bandThe band of tissue that runs over the bony point looks thicker than usual. It was found in 28.5 percent of people with this pain on ultrasound (Long et al., 2013).
Fatty atrophy or fatty infiltrationPart of the muscle looks replaced by fat. It is graded by how much, and it is one of the things a surgeon weighs if a tendon repair is being discussed.
Gluteus medius, gluteus minimus, greater trochanter
The two buttock muscles on the side of the hip and the bony point their tendons attach to. Medius attaches to the side and the upper back of the bony point, minimus to its front (the lateral, superoposterior and anterior facets).
Tendinosis, tendinopathy, tendinitis
The tendon looks thickened, or its normal pattern has changed on ultrasound or its signal is brighter on MRI. Tendinosis describes that look, tendinopathy is the name for a painful tendon problem, and tendinitis is an older word some reports still use.
Peritrochanteric edema or fluid, peritendinitis
Bright fluid signal on MRI around the bony point, in or around the tendons and the bursa; peritendinitis means it sits around a tendon. In one study it was found in 88 percent of hips with no pain on the outside (Blankenbaker et al., 2008).
Trochanteric bursitis, bursal thickening, bursal fluid or distension
The sac over the tendons looks thickened or holds more fluid than usual. Two smaller sacs, the subgluteus medius and subgluteus minimus bursae, sit under the tendons. In people with this pain, bursitis was less common on ultrasound than tendon changes (Long et al., 2013).

When to see a doctor first

Go to emergency

  • A fall onto the hip, or sudden severe pain, after which you cannot put weight on the leg

    Go to emergency now and keep weight off the leg. A hip fracture needs to be ruled out.

  • A hot, red or swollen outer hip and you feel unwell

    Go to emergency.

  • Groin pain in a runner and you cannot put weight on the leg, or the pain is severe

    Possible stress fracture of the hip. Go to emergency.

  • New trouble starting to pass urine or feeling it pass, new loss of bladder or bowel control, new numbness between the legs or around the back passage, new loss of genital sensation or sexual function, or severe or rapidly worsening weakness in both legs

    Go to emergency now. These can be signs of cauda equina syndrome.

Get seen today

  • A sudden pop or tearing pain at the side of the hip, followed by new weakness or a limp

    Same-day medical assessment. A tendon pulled off the bone, or a fracture, needs to be ruled out.

  • A newly hot, red or swollen outer hip, even without a fever

    Same-day medical assessment to rule out an infected bursa. Infection is possible even without a fever.

  • Groin pain in a runner that builds with each run, or hurts when you hop on that leg

    Possible stress fracture of the hip. Stop running and impact exercise, keep weight off the leg and get medical assessment today.

  • A new foot drop (the foot catches or slaps when you walk), or weakness in one leg that is getting worse

    Same-day medical assessment.

Check with your doctor

  • Severe pain that stays the same whatever position you are in, or new hip pain with unexplained weight loss or a history of cancer

    Not typical of tendon pain. See your family doctor promptly for a medical review before starting physiotherapy.

  • Numbness or tingling spreading down the leg, without the signs above

    Can be checked at your physiotherapy assessment; see your family doctor if it is spreading or getting worse.

What it does and does not tell you

The tendons are usually the source. Greater trochanteric pain syndrome is the umbrella name for pain at the bony point on the outside of the hip, and trochanteric bursitis is its older label. Tendinopathy of the gluteus medius and minimus is now recognised as a primary local source of this pain (Grimaldi et al., 2015). In 877 people with this pain scanned with ultrasound, about half showed gluteal tendinosis, more than a quarter a thickened iliotibial band and one in five bursitis (Long et al., 2013). A scan like this shows which tissues look changed; it cannot show on its own which one is causing the pain.

These findings are common in hips without pain on the outside. In 256 hips on pelvic MRI, tendon changes were found in half of the hips with no pain on the outside, and fluid signal around the bony point, an MRI sign used for both bursitis and tendinopathy, in 88 percent of them (Blankenbaker et al., 2008). In 2,851 hips scanned before keyhole surgery for hip impingement, 457 of the 871 hips with gluteus medius changes showed no sign of a problem on the outside of the hip when examined. Most of those were tendinosis, and symptom-free findings were about twice as likely from the age of 40 (Meghpara et al., 2020).

Tears turn up on the painless side too. Among 37 people having surgery for a gluteus medius tear who had symptoms on one side only, 27 also had a tear on the other, painless side. Ten of those 27 later developed symptoms there, all mild to moderate, and none needed surgery on that side within two years (Arvesen et al., 2022). Tears may still be more likely than tendinosis to matter: in the larger group scanned before impingement surgery, no full-thickness tear was free of symptoms (Meghpara et al., 2020).

The report tracks the pain loosely. In the pelvic MRI study, these findings were a poor predictor of who had pain on the outside of the hip, and neither the size and shape of the fluid signal nor partial-thickness tears differed between the painful hips and the others (Blankenbaker et al., 2008). Among the people with tears, the grade of a tear did not always match their symptoms or predict who would develop them (Arvesen et al., 2022).

It does not decide the treatment. What decides the plan is where the pain is, what sets it off and what the examination shows: tenderness at the bony point, pain standing on that leg, and the strength of the hip. A full-thickness tear with clear weakness or a limp is the main exception, covered below. If the report also describes the hip joint itself, such as cartilage loss, the hip osteoarthritis page covers that part, because the two can sit side by side.

Why lying on that side, crossing your legs and stairs hurt

Compression of the tendons against the bone, combined with a high pulling load, is thought to be the most damaging mix for these tendons, and positions that draw the thigh across the body (hip adduction) are a key factor (Grimaldi et al., 2015). The iliotibial band runs over the bony point, so when the thigh crosses the midline the band presses down on the tendons and bursa. In cadavers and during hip replacement operations, the force measured under the band at the bony point rose as the thigh was moved across the body and fell as it was moved outward (Birnbaum et al., 2004).

That matches the usual triggers. Lying on the painful side presses straight onto the bony point, and lying on the other side lets the top knee drop across the body. Crossing your legs, or standing with your weight hung on one hip, holds the thigh across the midline. Stairs, hills and standing on one leg ask the tendons for a strong pull while the band presses on them. This is why the plan starts with how you sleep, sit and stand, as well as with exercise.

What the evidence says about treatment

The trials point to advice about positions plus gradually built-up exercise as the core of care, with injections and shockwave as add-ons whose benefit is smaller or less certain.

  • Education and exercise. In the LEAP trial, 204 people aged 35 to 70 with more than three months of pain, and tendon changes confirmed by examination and MRI, had education plus exercise (14 sessions over eight weeks), one cortisone (corticosteroid) injection, or a wait-and-see approach. At eight weeks, 51 of 66 in the education and exercise group reported success, against 38 of 65 after the injection and 20 of 68 who waited. At a year, education and exercise still gave more people overall success than either, and pain was similar after exercise and the injection (Mellor et al., 2018).
  • Advice about positions. In a trial of 94 women after menopause, everyone was taught how to avoid compressing the tendons, then given either 12 weeks of targeted strengthening or placebo (sham) exercises. Both groups improved over a year with no overall difference between them, although the authors thought some people may benefit more from the strengthening (Ganderton et al., 2018). Because both groups had the same advice, the trial could not show how much the advice itself helped. I include it alongside exercise, as the LEAP trial did with its education.
  • Cortisone injection. In the LEAP trial an injection eased pain more than waiting at eight weeks, but fewer people reported overall success with it than with education and exercise, at eight weeks and at a year (Mellor et al., 2018). It can help when pain is stopping someone from starting the exercise.
  • Shockwave. Across eight trials of 754 people, shockwave gave less pain than the comparison treatments at two to four months, more so with focused shockwave than with the radial type. The gain in function at six months was smaller than people usually notice, and seven of the eight trials were at high risk of bias, meaning design weaknesses could have inflated the results (Rhim et al., 2024). The evidence is mixed; it may help alongside exercise when the tendon has not settled.
  • Tears and surgery. A 2026 review of gluteal tendon tears found only studies of surgery: 38 papers on 1,584 people, 35 of them reports on groups of patients with no comparison group (case series) and none a randomised trial. People improved in pain and quality of life a year or more after surgery, but the certainty was very low, and no study of non-surgical care for tears was found (Spencer et al., 2026). Reviews keep surgery for tendons that do not respond to other treatment (Grimaldi et al., 2015).

How I assess and treat a hip with this on the report

I start with where the pain is and what sets it off. Pain at the bony point on the outside of the hip that is worse lying on that side, on stairs, standing on one leg or with the legs crossed points to the tendons. Pain deep in the groin points to the joint itself, and the hip labral tear guide covers those findings. I ask how it started, because a fall or a sudden pop with new weakness is handled differently from pain that built up over months.

On examination I press on the bony point, see how long you can stand on that leg, test the strength of the muscles on the side of the hip, and watch whether the pelvis drops when you stand or walk on that side. I check how the hip joint moves and screen the lower back, because both can send pain to the same area. Then I read the report alongside what I found. I cannot order imaging; when further imaging would change the plan, I flag it to your family doctor and refer you.

For tendinosis, bursitis and partial tears the plan is usually the same: ease the compression first, with changes to how you sleep, sit and stand, then holds that push the leg outward without moving it, then strength built up step by step from two legs to one and back toward walking, stairs, hills or running. I usually leave out IT band stretching and foam rolling over the bony point, because both press on the same spot. Soft tissue work or dry needling to the surrounding muscles can sit alongside the exercise when it helps. The gluteal tendinopathy page sets out the exercise phases, and the hip bursitis page covers the same pain under its older name.

If the hip has not settled after a fair course, shockwave or an injection can be discussed. I do not give injections; when one makes sense, I coordinate with your family doctor or a sports medicine physician. If the report shows a full-thickness tear or a tendon pulled back from the bone, or you have a clear limp and weakness that is not improving, a surgical opinion through your family doctor is the next step. A tendon pulled off the bone by a fall or a sudden injury is worth that opinion promptly rather than after months of rehabilitation.

Gluteal tendinosis and bursitis questions I hear most

What does gluteus medius tendinosis mean?

The tendon of the gluteus medius, where it attaches to the bony point on the outside of the hip, looks thickened or changed on the scan. It describes how the tendon looks, not how much it hurts, and it is common in hips that have no pain. When it matches your symptoms and examination, it is usually treated with advice about positions and gradually built-up exercise.

Is trochanteric bursitis the same as greater trochanteric pain syndrome?

Greater trochanteric pain syndrome is the umbrella name for pain at the bony point on the outside of the hip, and trochanteric bursitis is its older label. Fluid or thickening in the bursa can be part of the picture, but the gluteal tendons are usually the main source, and on scans of people with this pain, bursitis was less common than tendon changes.

Is a partial tear of the gluteus medius serious?

Usually not on its own. Partial tears are found in hips without symptoms, including the painless side of people having surgery on the other hip, and they are usually managed like tendinosis, with advice and strength built up gradually. A tear with a clear limp or real weakness, or one that is not improving after a fair course of rehabilitation, is worth a doctor’s review and sometimes a surgical opinion.

Do I need surgery for a gluteal tendon tear?

Usually not. Surgery is kept for tears that keep causing pain and weakness despite a fair course of non-surgical care, and for a tendon pulled off the bone. The studies of surgery report improvement, but they are mostly case series without a comparison group, so the certainty is very low.

Will a cortisone injection fix trochanteric bursitis?

It can ease the pain for a while, but it does not rebuild the tendon. In the LEAP trial, an injection reduced pain more than waiting at eight weeks, but education plus exercise gave more people a good overall result at eight weeks and at a year, with similar pain at a year. An injection can be useful when pain is stopping you from starting the exercises.

Does shockwave therapy help gluteal tendinopathy?

It may ease pain for a few months. Across eight trials, shockwave gave less pain than the comparison treatments at two to four months, but most of those trials were at high risk of bias and the effect on function was small. Where it is used, it sits alongside the exercise rather than replacing it.

Why does my hip hurt when I lie on my side?

Lying on the painful side presses the tendons and bursa against the bony point. Lying on the other side lets the top knee drop across the body, which draws the iliotibial band tight over the same spot. A firm pillow between the knees, and another between the ankles, keeps the top leg level and can ease the night pain.

Can gluteal tendinopathy heal on its own?

It can settle with time, but more slowly and less often. In the LEAP trial, 31 of 60 people who waited reported success at a year, against 51 of 65 after education and exercise; in the exercise group, 51 of 66 had already reported success at eight weeks. The plan is guided by how the hip feels and what it can do, so a repeat scan is not usually needed.

Gluteal Tendinopathy: A Review of Mechanisms, Assessment and Management

Review. Tendinopathy of the gluteus medius and minimus is recognised as a primary local source of pain on the outside of the hip, mostly in mid-life and more often in women. Compression combined with high pulling load is thought to be the most damaging mix, with the thigh drawn across the body a key factor. Evidence for every treatment is limited, and surgery is reserved for cases that do not respond.
