== Definition/Description<br>  ==
* [[Sepsis|Septic]] trochanteric [[bursitis]]


&nbsp;For the definition of bursitis: [http://www.physio-pedia.com/Bursitis Bursitis].<br>In the hip region there are 4 different types of hip bursitis: Trochanteric bursitis, [http://www.physio-pedia.com/Iliopsoas_Bursitis iliopsoas bursitis], [http://www.physio-pedia.com/Gluteal_Bursitis gluteal bursitis] and [http://www.physio-pedia.com/Ischial_Bursitis ischial bursitis]. Trochanteric bursitis is the more common. It is pain over the lateral part of the hip, paraesthesiae in the legs, and tenderness over the iliotibial tract. The term greater trochanteric pain syndrome is now often substituted for trochanteric bursitis.[2] The condition is more prevalent among women than among men. [3] (level of evidence A1) but also among patients with coexisting low back pain, [http://www.physio-pedia.com/Osteoarthritis osteoarthritis], iliotibial band tenderness, and obesity.<br>In this article, the condition trochanteric bursitis will be treated<br><br>
If inflammatory signs such as redness, swelling and warmth are present, [[Septic (Infectious) Arthritis|septic arthritis]] should be suspected<ref name=":13" /><ref name=":15">Truong J, Mabrouk A, Ashurst JV. [https://www.ncbi.nlm.nih.gov/books/NBK470331/ Septic Bursitis.] InStatPearls [Internet] 2021 Sep 14. StatPearls Publishing.</ref>.  Sometimes septic bursitis can be present without these inflammatory signs and then aspiration is needed to confirm the diagnosis<ref name=":15" />. It can be acute, sub-acute or chronic<ref name=":15" />.

* Other causes of  trochanteric bursitis


The trochanteric bursae can be named as a cause of lateral hip pain, they lie above the lateral aspects of the greater femoral trochanter. There are four bursae that surround the greater trochanter. Three of them are present among most individuals. Bursae provides cushioning between bony prominences and the surrounding soft tissues. In this case they provide cushioning for the gluteus tendons, iliotibial band and tensor fascia latae.
Certain auto-immune diseases such as [[Rheumatoid Arthritis|rheumatoid arthritis (RA)]] can lead to trochanteric bursitis<ref>Suh JY, Park SY, Koh SH, Lee IJ, Lee K. [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8446489/ Unusual, but important, peri-and extra-articular manifestations of rheumatoid arthritis: a pictorial essay]. Ultrasonography. 2021 Oct;40(4):602.</ref> as well as crystal arthropathies such as [[gout]]<ref name=":13" />. Direct trauma could potentially also lead to isolated trochanteric bursitis. Isolated trochanteric bursitis due to repetitive rubbing/friction is possible<ref name=":14" /> but is very rare<ref name=":9" />.


Anatomically, there are two major bursitis and one minor that surround the greater trochanter.<br>The minor bursitis is called the gluteus minimus bursae, it is located cranial and ventral to the greater trochanter.The less important bursitis is the gluteus medius, this in contrast with the gluteus maximus. This last one is lateral to the greater trochanter and is situated between the gluteus medius tendon and the gluteus maximus muscle. It lies deep to the converging fibres of the tensor fascia latae. The iliotibial tract is formed by the gluteus maximus muscle and fascia. These powerful converging fibres are thus separated from the greater trochanter and from the attachment of the vastus lateralis muscle, situated by the bursa. In the illness greater trochanteric pain syndrome we mostly talk about the subgluteus maximus that is incriminated.

A bursa is a sac that usually contains a small amount of fluid and functions as a friction-reducing structure between two anatomical structures, e.g. bone and tendon<ref name=":13" /><ref name=":16">Ivanoski S, Nikodinovska VV.

The trochanteric bursa covers the posterior facet and lies deep into the gluteus maximus muscle. It also lies over the trochanter attachments of gluteus medius, gluteus minimus and vastus lateralis<ref name=":13" />. The sub gluteus medius bursa is situated at the lateral and superolateral facets deep to the gluteus medius tendon insertion while the sub gluteus minimus bursa is located between the anterior facet and gluteus minimus tendon<ref name=":13" />.

== Epidemiology /Etiology  ==
When there is GTPS with associated  trochanteric bursitis, the following are possible causes/contributing factors:


The prevalence of unilateral GTPS is 15.0% among women and 8.5% among men, and that of bilateral GTPS is 6.6% among women and 1.9% among men(16). In a study by Lievense et al. 1.8 in 1000 patients in primary care had the annual incidence of trochanteric pain (18) .The study also found out that trochanteric bursitis is more prevalent among females (80%) than among males.

== Differential Diagnosis  ==
Most cases of acute septic bursitis involve Staphylococcus aureus, followed by Streptococcus<ref name=":15" /> . Atypical mycobacteria or fungi are associated with chronic septic bursitis<ref name=":15" />. Septic bursitis, in general, is more common in men around the age of 50 years<ref name=":15" />. People who are more susceptible to septic arthritis, in general, include those with inflammatory arthritis (e.g. RA) and those with crystal arthropathies like [[gout]] (19).


Trochanteric bursitis is one of the pathologies that can cause lateral hip pain. The other pathologies that are associated with this pain could be: <br>• Gluteal tendonitis (gluteus medius or minimus muscles)<br>Gluteal muscle dysfunction (atrophy, tear,…) <br>• Iliotibial band disorders ( Snapping Hip syndrome) <br>• Femoral Fractures (Femoral neck stress fractur) <br>• Lumbar spine disease (including zygapophysical joints, sacroiliac joint, and intervertebral discs and ligaments) <br>• Ipsilateral and/or contralateral hip arthritis. <br>• Pain radiation patterns may complicate the diagnosis of GTPS because of anatomical overlap with the iliotibial tract and mid-lumbar dermatomes <br>• damage to the nerve supply of surrounding structures may elicit neuropathic symptoms that can stimulate GTPS <br>• chronic mechanical low back pain <br>• [http://www.physio-pedia.com/Rheumatoid_Arthritis Rheumatoid arthritis] <br>• leg length descrepancy <br>• Post surgical lumbar disk desease <br>• Radiculopthy or other neurologic sequelae <br>• [http://www.physio-pedia.com/Obesity Obesity] <br>• [http://www.physio-pedia.com/Fibromyalgia Fibromyalgia]<br>[6],[7](level of evidence 1A)<br>[4] (Level of Evidence 1A)<br>

There is no one specific test to confirm GTPS. Please see the [[Greater Trochanteric Pain Syndrome|GTPS]] page for a complete list of the tests that can be used. Concerning imaging, ultrasound can be used but is only indicated if conservative management has failed<ref name=":13" /><ref name=":3" />; if the diagnosis is unclear<ref name=":13" /><ref name=":3" /> or if the primary pathology is thought to be a gluteal tear<ref name=":13" />. MRI can be used for differential diagnosis<ref name=":7" /><ref name=":3" />.


== Outcome Measures  ==
In septic arthritis, [[antibiotics]] should only be started after blood cultures and inflammatory marker investigations have been done and should include white blood count, C-reactive protein and erythrocyte sedimentation<ref name=":15" />. Currently, the gold standard for diagnosis is aspiration and analysis of the bursal fluid<ref name=":15" />. Uric acid and rheumatoid factor should be ordered if one of these is suspected<ref name=":15" />. Imaging does not help diagnose septic arthritis and should only be conducted if other pathology, such as septic arthritis, is suspected<ref name=":15" />.

Physical examination is performed based upon the history of previous injuries and it is used to confirm the source of the pain23 and establish any limitations or deficits that the patient might have. It also assesses the underlying disorder or anatomical impairment that may cause a bursitis. <br>The physical examination must have a stepwise approach which includes inspection, gait, palpation, Range of motion, muscle strength and the execution of special tests.23 <br>The first part is the inspection. The most important aspect of inspection is the patient’s posture in a seated and upright position. 24 The patient with an irritated hip will tend to stand with the joint slightly flexed. In a seated position: slouching and leaning to the uninvolved slide allows the hip to seek a slightly less flexed position. The observation is also focused on the asymmetry, the gross atrophy, the spinal alignment or the pelvic skewness. <br>While observing the gait, one should look at leg length discrepancy, weakness and heel strike which contributes to the function of the gluteus maximus. 25<br>Bursae pain may be detected by palpation. We perform palpation to assess sources of the hip pain. The palpation starts with joint tenderness on the proximal and distal area of the hip. Also each part of the body that is associated with this injury must be assessed, e.g.: the bone, muscle, ligaments, etc. It is important to check the lumbar spine, sacroiliac joints, ischium, iliac crest, lateral aspect of the greater trochanteric bursa, muscle bellis and the pubic symphysis. They can determine a potential source of hip symptoms or pain. 23<br>The muscle strength can be assessed by resisted contraction which provokes symptoms. <br>The range of motion should be checked on the actual injured hip as well as on the contralateral hip. An active hip flexion, an internal and external rotation, an abduction and adduction will reproduce pain in the injured 4 area. The range of motion can be identified with several tests: the faber test, Trendelenburg test, Ober’s test, Thomas test and a test whereby the forced flexion combined with internal rotation could be helpful in diagnosing the cause of lateral hip pain. <br>23 level of evidence: 1A<br>24 level of evidence: 1A<br>25 level of evidence: 4<br><br>

There are several ways to treat trochanteric bursitis, depending on whether or not the bursitis has an infection, and whether it is necessary to treat the lesion with or without surgery. <br>Nonsurgical treatment21
* [[Rheumatoid Arthritis|RA]]<ref name=":15" />
 
Aseptic trochanteric bursitis19,20<br>In most cases trochanteric bursitis is treated without surgery. If the pain results from overuse, it is recommended to reduce the activities and change the way of doing them. <br>Furthermore, an exercise program of stretching and strengthening with a physiotherapist will help to bring back full range of motion in the hip, sometimes in combination with anti-inflammatory medications or heat and ice applications to calm inflammation. <br>Improving strength and coordination in the buttock and hip muscles also enable the femur to move in the socket smoothly and can help reduce friction on the bursa.<br>If the above treatment fails to reduce the symptoms, an injection of cortisone into the swollen bursa may be required. This anti-inflammatory injection will reduce the symptoms for months, but it will not cure the problem itself. <br>Septic trochanteric bursitis19,20<br>Infectious trochanteric bursitis does occur, but only in exceptional cases. <br>Further examination of the bursa fluid in the laboratory is necessary to assess which bacteria has caused the infection. Once this is known, an (intravenous) antibiotic therapy can be prescribed. <br>Surgical treatment21<br>Only when the nonsurgical therapy fails, and when the pain is still unbearable, it is recommended to consider surgery. The aim of surgery is to remove the thickened bursa and bone spurs that have arisen on the greater trochanter. Also the large tendon of the gluteus maximus is treated. Some doctors prefer to remove a part of the tendon that rubs against the greater trochanter while others prefer to lengthen the tendon somewhat.

== Physical Therapy Management <br>  ==
 
There are several treatments that can be used to reduce pain and swelling on a patient with trochanteric bursitis. When pain is the main complaint, we can relieve the pain for other underlying disorders so as to treat them more effectively.<br>Physical therapy is given to improve flexibility, muscle strengthening and joint mechanics. When these aspects are improved, pain will decrease. To heal trochanteric bursitis it is necessary to proceed to infiltration of the bursa with antiphlogistic medication (Corticosteroid-injections). In case of a persistent bursitis, surgery has to be considered as well. Other physical therapy interventions are the use of ultrasound, moist heat and educating the patient on activity modification and correcting possible training errors. <br>The pain of this injury can be reduced in different phases: The first phase is to manage the pain and the inflammation. Pain being the main reason for treatment of the trochanteric bursitis, we can use two common treatments to decrease the pain: the use of ice and non-steroidal anti-inflammatory drugs (NSAIDs). The bursa inflammation can be treated with ice therapy and techniques or exercises that reduce the inflammation structures. There are also other treatments that a physiotherapist can use, e.g.: electrotherapy, acupuncture, taping techniques, soft tissue massage and the temporary use of a mobility aid to off-load the affected side. <br>The second phase is to reinforce the patient’s strength and to restore the normal ROM. The physiotherapist will also to improve the muscle length and resting tension, the proprioception, balance and gait. <br>The next phase of rehabilitation is the restoration of all functions. Many patients catch TB due to their common daily activities like running, walking, … . The goal of the physiotherapist is to provide a specialized program for the patient to improve the movement and to reduce the pain, so that the patient can perform his daily activities. <br>The final phase is to prevent a relapse. It may be as simple as training your abdomines or performing some foot orthotics to address any biomechanical faults in the legs or feet. The therapist will examine your hip stability and function by addressing any deficits in the core strength and balance. Furthermore, he will also teach the patient some self-management techniques. The ultimate goal is to see the patient safely returning to his former sporting or leisure activities!<br>30 level of evidence: 5A<br>31 level of evidence: 1A<br>

Definition/Description[edit | edit source]

Trochanteric bursitis was first described in 1923 [1][2]and was used to describe lateral hip pain[2][3] thought to be caused by inflammation of the trochanteric bursa.

The continued use of trochanteric bursitis for lateral hip pain is however unsuitable as bursitis implies inflammation yet three of the four cardinal inflammatory signs, namely rubor, tumour and calor[1][2] [4]are rarely present[1][2].  Studies have revealed that trochanteric bursitis is rarely present in isolation [3][5] and that there is a low prevalence of trochanteric bursa inflammation[3][6] in patients with lateral hip pain. More recently it has become clear that gluteal tendon pathology (gluteal tendinopathy or gluteal tendon tears[1][2][3][7][8]or external coxa saltans [9][4] is more likely the primary cause of the lateral hip pain and that associated trochanteric bursitis can be present[1][2][3][7][8].  The gluteal tendon pathology or external coxa saltans with the possible associated trochanteric bursitis is now referred to as greater trochanteric pain syndrome (GTPS)[2][6][7][8]. If there is GTPS and an associated bursitis, the bursitis can occur in the subgluteus maximus (trochanteric bursa), subgluteus medius or subgluteus minimus bursa but it most commonly occurs in the trochanteric bursa[8].

In the rarer cases of isolated trochanteric bursitis, the causes could include:

If inflammatory signs such as redness, swelling and warmth are present, septic arthritis should be suspected[8][10].  Sometimes septic bursitis can be present without these inflammatory signs and then aspiration is needed to confirm the diagnosis[10]. It can be acute, sub-acute or chronic[10].

  • Other causes of  trochanteric bursitis

Certain auto-immune diseases such as rheumatoid arthritis (RA) can lead to trochanteric bursitis[11] as well as crystal arthropathies such as gout[8]. Direct trauma could potentially also lead to isolated trochanteric bursitis. Isolated trochanteric bursitis due to repetitive rubbing/friction is possible[9] but is very rare[3].

Clinically Relevant Anatomy[edit | edit source]

Trochanteric Bursitis.jpg

A bursa is a sac that usually contains a small amount of fluid and functions as a friction-reducing structure between two anatomical structures, e.g. bone and tendon[8][12]. Bursitis is characterised by soft-tissue swelling, localised pain, synovial thickening and increased fluid in the bursa[12].

The trochanteric bursa covers the posterior facet and lies deep into the gluteus maximus muscle. It also lies over the trochanter attachments of gluteus medius, gluteus minimus and vastus lateralis[8]. The sub gluteus medius bursa is situated at the lateral and superolateral facets deep to the gluteus medius tendon insertion while the sub gluteus minimus bursa is located between the anterior facet and gluteus minimus tendon[8].

Epidemiology /Etiology[edit | edit source]

When there is GTPS with associated  trochanteric bursitis, the following are possible causes/contributing factors:

GTPS is more common in women in their 4th to 6th decades of life[1][7]. A recent study found that only 2% of women had isolated trochanteric bursitis, while 25% had hip abductor tendon pathology with an associated trochanteric bursitis[3].

Septic bursitis occurs when bacteria is introduced into the bursa[14] and can occur due to:

  • Tuberculosis infection (less than 2% of musculoskeletal tuberculosis presents as septic trochanteric bursitis)[4][8][16]
  • Direct puncture of the skin[10]
  • Micro-trauma[10]
  • Cellulitis of the skin that is adjacent to the bursa[10]

Most cases of acute septic bursitis involve Staphylococcus aureus, followed by Streptococcus[10] . Atypical mycobacteria or fungi are associated with chronic septic bursitis[10]. Septic bursitis, in general, is more common in men around the age of 50 years[10]. People who are more susceptible to septic arthritis, in general, include those with inflammatory arthritis (e.g. RA) and those with crystal arthropathies like gout (19).

Characteristics/Clinical Presentation[edit | edit source]

  • Lateral hip pain[2][8][17]
  • Pain to the lateral thigh and knee[2][8][17]
  • Local tenderness over the greater trochanter[2][8][17]
  • Pain with side-lying on the affected side[2][8][17] and sometimes when lying on the unaffected side too due to hip adduction on the affected side[17]
  • Pain with weight-bearing activities[2][8][17]
  • Pain with sitting crossed-legged[17]
  • Pain with prolonged sitting[2][8]

Diagnostic Procedures[edit | edit source]

There is no one specific test to confirm GTPS. Please see the GTPS page for a complete list of the tests that can be used. Concerning imaging, ultrasound can be used but is only indicated if conservative management has failed[8][17]; if the diagnosis is unclear[8][17] or if the primary pathology is thought to be a gluteal tear[8]. MRI can be used for differential diagnosis[1][17].

In septic arthritis, antibiotics should only be started after blood cultures and inflammatory marker investigations have been done and should include white blood count, C-reactive protein and erythrocyte sedimentation[10]. Currently, the gold standard for diagnosis is aspiration and analysis of the bursal fluid[10]. Uric acid and rheumatoid factor should be ordered if one of these is suspected[10]. Imaging does not help diagnose septic arthritis and should only be conducted if other pathology, such as septic arthritis, is suspected[10].

Differential Diagnosis[edit | edit source]

Multiple structures can present as lateral hip pain. In the absence of inflammatory signs, differential diagnosis can include:

If inflammatory signs are present:

Outcome Measures[edit | edit source]

• VISA-G - GTPS-specific outcome measure[18]

Physiotherapy Management[edit | edit source]

If trochanteric bursitis is associated with GTPS, the primary problem will need to be addressed. Please see the Physiopedia pages GTPS, gluteal tendinopathy and coxa saltans on how to manage the primary problems of the associated trochanteric bursitis. For the management of specifically the associated bursitis, please see the medical and surgical management below. The videos below simplifies Trochantric bursitis and it's physiotherapy management

Medical Management[edit | edit source]

Corticosteroid injections can be used to manage the associated bursitis in GTPS but they only provide short-term relief[6]. Platelet-rich plasma (PRP) has also been found to be a feasible option[21][22], but it is unknown whether corticosteroid injections or PRP are more effective.

Non-steroidal anti-inflammatory drugs (NSAIDs) may provide analgesia in the acute phase of GTPS or primary bursitis. Still, if the GTPS is chronic, NSAIDs are not advised as they may have a detrimental effect on tendon healing[8].

Septic bursitis is managed with antibiotics and if pain management is needed, NSAIDs can be used[10]. If the NSAIDs are insufficient, corticosteroid injection can be used[10]. TB trochanteric bursitis is also managed with antibiotics but treatment continues for much longer, usually 6-18 months[23].

Surgical Management[edit | edit source]

Indications for surgery for septic arthritis include[10] significant swelling, severe cases that aren’t responding to antibiotics alone or chronic or recurrent cases. Operative interventions include:

  • Suction irrigation[10]
  • Needle aspiration in conjunction with systemic antibiotics[10]
  • If aspiration fails, incision and drainage[10]
  • Bursectomy[10][16][23]

In GTPS, surgical intervention is only indicated if conservative management has failed[7] or if there is a significant tendon tear[17]. Surgical options for GTPS, without a tendon tear, that are safe and effective include:

For gluteal tendon tears, a reconstruction/repair[27] [28]is done. Please see this reference[27] for the rehabilitation protocol after abductor tendon repair.
