Lateral hip pain is a very common occurrence amongst the general population and even more-so for middle-aged women, who demonstrate a 4x higher prevalence then men. In fact, literature has found that 23.5% of women over the age of 50 indicate having persistent lateral hip pain (15% unilateral and 8.5% bilateral)1.

Pain in this region can be caused by various anatomical and neurovascular structures, from the sacroiliac joint to referral from the lumbar spine. However, among these potential structures, the greater trochanteric bursa has historically been to blame2,3 and is likely the most common source…

Or is it?

The beginning of the end for Trochanteric Bursitis started with a study conducted by Bird and colleagues in 20014. With the hypothesis that gluteus medius tendinopathy was the prevailing underlying pathology in lateral hip pain, they evaluated 24 patients via magnetic resonance imaging. The results very much fell in line with their hypothesis as 45.8% had a gluteus medius tear, 62.5% had gluteus medius tendinopathy, and only 8.3% presented with trochanteric bursal distension.

A 2007 study conducted by Silva and colleagues5 set out to further understand whether this persistent lateral hip pain can actually be blamed on an inflamed trochanteric bursa. This prospective, case-controlled, blinded study attempted to determine the histopathologic features of patients with greater trochanteric bursitis versus asymptomatic control subjects. Bursal specimens were obtained following each subject undergoing total hip arthroplasty on the involved hip. Two different blinded surgical pathologists evaluated the samples and found no signs of acute or chronic inflammation in the control or greater trochanteric bursitis groups. Unfortunately, this study had a few significant limitations. One being that it was an extremely small sample size (6 subjects) and the other being that all subjects were undergoing a THA on the involved hip.

Similar to the original article in 2007, Board and colleagues also compared pathohistolgical composition of the trochanteric bursa in individuals undergoing ipsilateral THA. However, this study was performed on a much larger scale with 100 subjects included (50 with greater trochanteric pain and 50 without pain in this region). Once again, this study found no evidence of acute or chronic inflammation in the 100 included subjects, however 20% of subjects in the ‘trochanteric bursitis’ group demonstrated thinning of the gluteus medius tendon6.

This led the authors to conclude…

It is perhaps best to view any involvement of the trochanteric bursae within Greater Trochanteric Pain Syndrome as a secondary event with the inciting initial pathology stemming from either involvement of the ilio-tibial band or from the ‘abductor cuff’ of the hip that is the gluteus medius and minimus tendons — Board et al., 2014

And to continue beating a dead horse, another study demonstrated more confirmatory findings. Long and colleagues7 more recently published a much larger study trying to answer the same question. This retrospective review of musculoskeletal sonographic findings of 877 patients with greater trochanteric pain demonstrated very similar results. Of the included subjects, 700 (79.8%) did not have trochanteric bursitis on ultrasound. The most commonly involved pathological conditions were gluteal tendinosis (438; 49.9%) and a thickened iliotibial band (250; 28.5%).

What’s in a name?

Lateral hip pain… Trochanteric Bursitis… Greater Trochanteric Pain Syndrome (GTPS).

Why does it matter what we call pain localized to the greater trochanteric region? When we think “-itis”, understandably we jump to the conclusion that this an inflammatory disorder and more specifically an inflammatory condition of the bursa in the case of trochanteric bursitis. This then leads to interventions that act to decrease inflammation of the involved structures. These conservative interventions likely start at NSAIDs and end at cortisone injections prior to the eventual progression to surgical interventions. When we look at the interventions studied in the case of GTPS, there is an overwhelming predominance of anti-inflammatory procedures. A systematic review of conservative treatment for GTPS included 8 studies (696 patients). Of these 8 studies, 6 investigated cortisone injections, 2 on extracorpal shockwave therapy, 1 on orthotics, and 1 on ‘home training’8.

That is right, there has yet to be a study looking at activity modification or physical therapy in the treatment of greater trochanteric pain syndrome (however there are two large studies currently underway). And the one study looking at ‘home training’ left A LOT to be desired. This lack of understanding related to the underlying pathology in GTPS has led to an over-reliance on anti-inflammatory interventions in the literature and in clinical practice.

Now that we have all but eliminated trochanteric bursitis from contention, maybe we can finally determine the best way to treat this complex condition…

  1. Great article. I don’t know how many patients have told me their problem is the bursa because their medical doctor told them that was the problem. I keep telling them its just one of the possibilities. Keep up the good work!

  2. 2001 study-24 sample size, 2007 and similar study limitations already mentioned, more to do with THR, last study conclusion based on ultrasound (and not MRI) study, that too doesn’t refute bursa involvement in at least 20%? So how is this a dead horse? After failed conservative treatment, a CSI is an excellent intervention at least for diagnostic sake in gtps if one suspects bursitis, the key is to identify the correct patient and keep options open. Finally in 17 yrs of practice, I am yet to come across a patient who had surgical intervention for gt bursitis.


    1. Sunit, sorry for the delayed response and thank you for the comment!

      I am definitely aware of the limitations in the available literature and those factors were included in the above article, however in each and every study, the proportion of trochanteric bursa involvement is either nonexistent or a consequence of other underlying pathology (at best). While the trochanteric bursitis is possible, the involvement of the gluteal musculature and proximal iliotibial band is likely a more accurate origin of symptoms in most patients.

      CSI do provide short-term pain relief in some cases… A recent systematic review demonstrated a reduction in symptoms for < 3 months (Barratt et al., 2016 —, but no significant long term improvements. CSI has a place in management, but does not necessarily implicate the trochanteric bursa and it is far from a long-term solution.

      Additionally, sonographic evaluation of the trochanteric region has quite a bit of support in the literature and I would not consider its use inferior to MRI evaluation…

  3. Hi all ..end of the day whats the cause ? In my experience its always pelvic malalignent ,dysfunction at L5/S1 leading to alterations in nerve output on the dysfunctional side = glut med weakness and the bursitis is the ” EAP ” ..end of adaptive potential …fix the bones re set the nerves,TvA,Multifidii.hip rotators, and of all muscles in the body glut med fires super fast up fast and pelvic balance is restored.Back to basics ..research is grand but lets not outsource clinical reasoning ….


  4. TvA is short for trans versus abdominis : I frequently note a marked imbalance between the right and left sides in association with pelvic misalignment. Often the SI issue is secondary to capsular changes on the painful bursa side.


  5. …And don’t forget to rule out lumbar spine pathology (L4 and L5) as a primary source of hip pain. We often treat the pain area assuming this is the source when it possibly may arise from the lumbar spine. Unfortunately, I made this mistake. Conservative treatment helped me for a while but I ultimately had to resort to a 2-level fusion and laminectomy. My hip and SI joint pain resolved once I was able to start rehabilitation. I ultimately recovered a lengthy rehab process and am mostly back to normal activities.

    1. Thanks for the comment Brad and I 100% agree with you. The lumbar spine should be ruled out in almost any lower quarter painful condition. After performing a thorough repeated movement examination and neurodynamic testing, we can focus on the joints distal to the lumbar spine.

      Sorry to hear that you had to go under the knife, but it sounds like you are moving in the right direction now!
