Greater Trochanteric Bursitis Kathy Mulford ABSTRACT Greater trochanteric bursitis is a common regional pain syndrome which frequently simulates major hip diseases and low back pain. Symptoms include pain over the lateral hip area with occasional radiation of pain into the lateral thigh. It is commonly seen between the fourth and sixth decades of life but can be seen in all age groups. Treatment includes local glucocorticoid injections combined with physical therapy and anti-inflammatory medication. Patient education is important in the success of treatment. This article reviews the anatomy, causes, symptoms, diagnosis, and treatment of greater trochanteric bursitis. Keywords: bursitis, glucocorticoid injections, hip, low back pain 328 The Journal for Nurse Practitioners - JNP G reater trochanteric bursitis is a frequent but overlooked clinical condition, mimicking major hip diseases, low back pain, and nerve root pain associated with low back pain. The condition is characterized by pain in the region of the greater trochanter, lateral thigh, and buttocks. Because greater trochanteric bursitis is frequently misdiagnosed as other diseases, it is important for practitioners to understand the causes, symptoms, and treatment of this condition. ANATOMY Studies have shown that up to 21 bursae can be found in the hip region.1 Four bursae surround the greater trochanter; three are constant (two major and one minor). The minor bursa is the gluteus minimus bursa, which lies above and slightly anterior to the proximal superior surface of the greater trochanter.The two major bursae include the subgluteus medius and the subgluteus maximus bursa.The gluteus medius is situated posterior and superior to the proximal edge of the greater trochanter. The subgluteus maximus is lateral to the greater trochanter. It is almond shaped, 4 to 6 cm in length, and 2 to 4 cm in width (Figure 1).This bursa functions as a gliding mechanism for the anterior portion of the gluteus maximus as it passes over the greater trochanter to insert into the iliotibial band. Any irritation to these bursae can result in symptoms of greater trochanteric bursitis. It is important to note that, in addition to constant bursae or ones that a person is born with, bursae develop to cushion areas of friction.These are called adventitious bursae. May 2007 CAUSE Greater trochanteric bursitis can be caused by trauma (23%-44%),2 but more often it is associated with repetitive microtrauma caused by active use of the muscles inserting on the greater trochanter.This microtrauma results in degenerative changes of tendons, muscles, or fibrous tissues.3 Predisposing factors associated with greater trochanteric bursitis include alterations in the biomechanics of the lower extremities resulting from osteoarthritis of the hip joint, degenerative disc disease of the lower spine, and leg-length discrepancy. Other conditions are listed in Table 1. Because no known definitive studies link cause and effect in greater trochanteric bursitis and these conditions, one can only casually relate these conditions to greater trochanteric bursitis.The incidence of greater trochanteric bursitis is well documented with peaks between the fourth and sixth decades of life, although it has been reported in all age groups. Studies have also shown a greater incidence in women than in men.4 SYMPTOMS Greater trochanteric bursitis is characterized by intermittent pain over the lateral aspect of the hip. It is usually aching in nature but can be intense. This pain is usually chronic but may on occasion be acute or subacute. The pain can radiate into the lower buttocks and the lateral aspect of the thigh, but it rarely extends into the posterior aspect of the thigh or below the knee. Occasionally, patients experience numbness in the upper thigh with no specific dermatomal pattern. Patients report pain from greater trochanteric bursitis with a variety of activities or movements. The most common trigger reported is prolonged standing or lying on the affected side.5 Climbing stairs and running are also triggers. Any movement of the affected hip can reproduce the pain of greater trochanteric bursitis, but external rotation and abduction of the hip are most common. Getting in or out of a car and placing a foot on the opposite knee (as if to tie one’s shoe) are examples of these movements. Greater trochanteric bursitis can cause varying degrees of disabilities. The most common disability is exercise limitations to include walking. It is also associated with broken sleep patterns secondary to the inability to lie on the affected side because of pain. In addition, a large number of patients have bilateral bursitis, further interrupting sleep patterns. www.npjournal.org Figure 1. Anatomy of the greater trochanteric bursa.

Hip Bursitis Hip Joint Inflamed Trochanteric Bursa Femur Muscle PHYSICAL EXAMINATION Pinpoint tenderness over the greater trochanter area is the hallmark physical finding in all symptomatic patients. Tenderness may extend into the lower buttock and lateral thigh but not to a significant degree. While the patient is standing, palpate the lateral hip area in a cephalic direction beginning below the greater trochanter eminence until the area of maximal tenderness is identified. This technique may also be done with the patient lying down on the unaffected side. Pain can also be reproduced by resisted abduction and external rotation. To perform resisted abduction, place the patient in a sitting position with knees flexed. The examiner places his or her hand on the lateral aspect of the upper thigh and instructs the patient to move the thigh laterally against the resistance. External rotation of the hip is obtained by placing the patient in a sitting position with the knees flexed and adducting the lower leg (shin). Pain on flexion and extension of the hip is indicative of intraarticular hip disease and not usually greater trochanteric bursitis. Objective swelling is rare because of the bulky muscles overlying the deep structures of the trochanter bursa. Other physical findings such as limited lumbar range of motion and muscle atrophy may reveal other associated conditions such as lumbar spondylosis and nerve root compression.

DIAGNOSTIC STUDIES X-rays of the hip, pelvis, and lower spine may show evidence of one or more of the associated musculoskeletal conditions; however, there are no definitive x-ray findings of greater trochanteric bursitis. On occasion, calcifications around the greater trochanter may be seen (approximately 40% of patients with greater trochanteric bursitis).6 These calcifications vary in size and shape from a few millimeters to 3 to 4 cm in diameter. They appear as linear or small, rounded masses that are separated or grouped together. Irregularities can also be seen on the surface of the greater trochanter. Bone scans may show increased uptake in the area of the greater trochanter, and magnetic resonance imaging scans or sonography may show a highintensity signal in the greater trochanter area, but all of these findings may not always have actual clinical significance and vice versa.7 DIAGNOSIS Diagnosing greater trochanteric bursitis is based mainly on clinical findings. A typical history of pain on ambulation and disruptive sleep because of the pain of lying on the affected side associated with physical findings of ten330 The Journal for Nurse Practitioners - JNP derness to palpation solidify the diagnosis. Associated conditions such as lumbar spondylosis and degenerative disc disease or degenerative joint disease of the hip must be differentiated and treated accordingly. CLINICAL SCENARIO A 65-year-old woman comes to the office complaining of right-sided buttock and hip pain. She reports that her symptoms began a little over 3 weeks ago and have gradually worsened. The symptoms are aggravated by walking, going up stairs, and lying on the affected side. She also reports extreme tenderness to touch over the outside of her hip area and pain with movement of her hip joint. She denies any trauma, fever, or chills. She denies groin pain; however, she does report occasional lateral thigh pain. She has used heat to the area and Aleve occasionally with no relief. She is worried about arthritis of the hip and fears needing a hip replacement. Past medical history is positive for lumbar degenerative disc disease, acid reflux, and high cholesterol. Past surgical history and family history are noncontributory. Social history: Patient is a widow, lives alone in a two-story house, and works as a legal secretary. She is a nonsmoker and is very active in her community doing volunteer work. Physical examination finds a well-developed, wellnourished, woman in moderate distress. She has buttocks or hip pain when standing from a sitting position but walks with a normal gait. She has moderate limited range of motion of the lumbar spine with mild pain and limited hip abduction secondary to hip pain. No erythema or edema is seen over the right buttocks or hip area. Marked tenderness to palpation is found over the right greater trochanteric area. She is neurologically intact in the lower extremities. Plain x-rays of the lumbar spine (three views: anteroposterior [AP], lateral, and lateral standing) and an AP of the pelvis were obtained. Findings include moderate lumbar spondylosis with disc space narrowing at the L4 to S1 levels. No lumbar fractures or spondylolisthesis is seen. AP of the pelvis shows no fractures or dislocations. There is minimal degenerative joint disease (DJD) of the hips bilaterally. Diagnosis includes the following: (1) right-sided greater trochanteric bursitis, (2) lumbar spondylosis L4 to April 2007 ® S1, (3) degenerative disc disease L4 to S1, and (4) minimal bilateral DJD of the hips. Even though this patient obtained excellent results with her treatment for greater trochanteric bursitis, many patients require several months of physical therapy and anti-inflammatory medications to obtain such results. Treatment includes the following: (1) greater trochanteric bursa injection with lidocaine, Marcaine, and triamcinolon (Kenalog); (2) ice to area (20 minutes on and 20 minutes off) for 48 to 72 hours while awake; (3) avoid strenuous activity and frequent stair climbing; (4) Celebrex 200 mg every day with food; (5) begin physical therapy 2 to 3 times a week for 4 to 6 weeks; (6) reevaluate at follow-up in 5 weeks; and (7) provide education on diagnosis and prevention. At the follow-up visit 5 weeks later, the patient reports marked reduction in right-sided hip pain. She continues physical therapy twice a week and has begun a home exercise program. She recognizes the importance of daily stretching and the avoidance of repetitive bending and twisting. Even though this patient obtained excellent results with her treatment for greater trochanteric bursitis, many patients require several months of physical therapy and anti-inflammatory medications to obtain such results. It is important to educate the patient about the chronicity of this malady.

Studies looking at the success of glucocorticoid injections showed response rates ranging from 60% to 100% after one or more injections.1 Current treatment consists of activity modifications; physical therapy modalities, including ice, heat, and diathermy; nonsteroidal anti-inflammatory medications; and glucocorticoid injections. Most patients are initially treated with physical therapy, activity modifications, and anti-inflammatory medication. Because greater trochanteric bursitis can take 2 to 3 months if not longer to resolve, it is important to educate the patient about this time line. If these treatments are ineffective in resolving symptoms, the use of glucocorticoid injections is considered. In my current practice when an injection is indicated, the point of maximum tenderness is identified and 5 mL 1% lidocaine and 5 mL 0.25% Marcaine are infiltrated widely around the area and as deep as the surface of the bursa. This injection is followed by a combination of 40 mg triamcinolone, 7 mL 0.25% Marcaine, and 2 mL 1% lidocaine. Half of this injection is placed at the point of maximal tenderness, and the rest is peppered in the area surrounding the bursa. A 22-gauge 3.5-inch spinal needle is used. Complications are rare but can include sterile abscess, granulomatous reaction, soft tissue and nerve injury, and skin atrophy especially in repeated injections. My practice does not advise more that two or three injections in one bursa in a 12month period. It is also our practice to continue physical therapy, anti-inflammatory medication, and activity modifications after injections. Educating the patient about length of time for recovery and the importance of continued treatment after injections is imperative for success in relieving the symptoms. It is also important to educate the patient about the triggers that can cause future flares and how to prevent them. to treatment, it is important for health care providers to include this diagnosis in their differential when evaluating hip pain.

Causes of hip pain often are attributed to disorders in the lower back or hip joint. Greater trochanteric bursitis is often underdiagnosed as a cause of hip pain despite its characteristic symptoms of diffuse pain in the buttocks and lateral thigh.
