Abstract
BACKGROUND Trochanteric Bursitis (TB) is a common reason to seek primary care, previously shown to be associated with female gender and obesity. Diabetes mellitus (DM) has several musculoskeletal manifestations, but was never found to be associated with TB. PURPOSE To explore the association between DM and TB, based on a large database. The secondary aim was to explore the influence of gender and insulin usage on the occurrence of TB. STUDY DESIGN cross-sectional study. METHODS A population-based cohort consisting of 60,610 patients (55,428 without DM and 5182 with DM), of whom 5418 were diagnosed with TB. A logistic regression model was applied to estimate propensity scores. RESULTS The odds of individuals with DM being diagnosed with TB were 55.8% higher compared to the odds of patients without DM (OR: 1.558, 95% CI: [1.429, 1.70], p < 0.0001). We found that insulin users had a lower risk of TB than patients not using insulin (log-rank p < 0.0001). Females are 3.3 times more likely to have TB than males (RR: 3.337, 95% CI: [3.115, 3.584], p < 0.0001). CONCLUSIONS DM is a risk factor for developing TB. Insulin had a protective effect against TB, suggesting that better glycemic control might prevent this painful infliction.

Abstract
BACKGROUND The best treatment of degenerative hip abductor tendon lesions remains largely unknown, as the natural course of the disease has not yet been reported. The aim of the present study was to investigate the natural history of symptomatic degenerative hip abductor lesions. HYPOTHESIS Nonoperatively treated hip abductor lesions progress over time, resulting in refractory hip pain and low functional outcomes. STUDY DESIGN Case series (prognosis); Level of evidence, 4. METHODS Consecutive patients with greater trochanteric pain syndrome and degenerative changes on magnetic resonance imaging (MRI) of the symptomatic hip were included. Bilateral hip MRI scans and a clinical examination were performed at a minimum follow-up of 36 months to study the type and location of hip abductor lesion. Progression of a lesion was defined as a more severe lesion as compared with the initial MRI results or if the lesion extended to another, initially not involved, trochanteric facet. The muscle's fatty infiltration (FI) was also described. RESULTS From 106 patients identified, 58 patients (64 hips) aged 66 ± 14 years (mean ± SD) agreed to return to the clinic for follow-up MRI and met the inclusion criteria. At a mean 71-month follow-up, an overall 34% (22/64) of lesions had progressed over time: from trochanteric bursitis to tendinopathy (9/64, 14%) or partial tear (5/64, 8%), from tendinopathy to partial tear (4/64, 6%), from a partial to complete tear (3/64, 4.5%), and with 1 complete tear (1/64, 1.5%) extending to another trochanteric facet. Interestingly, 90% of partial tears remained stable or transformed into a scar. Although patients with a progressive lesion experienced more trochanteric pain (visual analog scale, 4.6 vs 2.8; P = .001), the functional outcomes were comparable with patients with a stable lesion. The majority of hips with a partial tear (64%) demonstrated a progression of gluteus minimus FI from a median grade of 1 to 2, whereas only 1 hip (3%) progressed from grade 2 to 3. Only 3 hips (9%) with a partial tear had a progression of gluteus medius FI, which did not differ significantly from the contralateral unaffected side. CONCLUSION Nonoperative treatment might be a valid long-term option for degenerative hip abductor lesions, especially for partial tears, which demonstrated a low risk of clinically relevant progression or muscle FI and similar clinical outcomes to those reported in the literature for operatively treated hip abductor tendon lesions.

Abstract
BACKGROUND Trochanteric bursitis or greater trochanteric pain syndrome is a common disorder and frequent cause of lateral hip pain. It can lead to severe functional impairment with increase morbidity and poor quality of life.The purpose of the current study was to identify and evaluate relationship between health-related factors, as prognostic indicators, and clinical outcomes. METHODS A single-centre, prospective study was conducted and 60 patients (62 hips) were included with a minimum 12 months of follow-up. Clinical outcomes were evaluated using Hip Outcome Scale, Single Assessment Numeric Evaluation and Visual Analogue Scale. Radiological assessments and health-related factors were documented in an attempt to understand their validity as predictors of clinical outcomes. Complications and recurrence rates were also analyzed. RESULTS Univariate model revealed that an increased BMI (p = 0.001; OR = 1.05; 95% CI, 1.02-1.07); number of previous corticosteroid infiltrations (p = 0.001; OR = 1.28, 95% CI, 1.11-1.48); longer time from symptom onset to surgery (p = 0.001; OR = 1.19; 95% CI, 1.12-1.28); smoker status (p = 0.001; OR 11.2; 95% CI, 3.30-44.2); and the presence of prior lumbosacral fusion (LSF) (p = 0.001; OR 13.8; 95% CI, 2.96-101); were prognostic factors predisposing for poor clinical outcomes.Among prognostic health-related factors were medical comorbidities such as emotional distress (p < 0.001; OR 26.1; 95% CI, 5.71-192); fibromyalgia (p = 0.026; OR 3.56; 95% CI, 1.16-11.7); and hyporthyroidism (p = 0.005, OR = 6.55, 95% CI, 1.73-28.7). CONCLUSIONS Better overall physical function was predicted by lower number of corticosteroid infiltrations, shorter time span from symptom onset to surgery, non-smoker status and the absence of prior lumbosacral fusion. Obesity, smoking, the presence of emotional distress, fibromyalgia and hypothyroidism seem to increase the risk of poor clinical outcomes. A proper selection and/or correction of modifiable prognostic factors could reduce the incidence of endoscopic treatment failure and, as a consequence, improve patient outcomes and quality of life. However, future efforts should focus on experimental and randomised studies to fully determine these associations.

Abstract
BACKGROUND Greater trochanteric pain syndrome (GTPS) is a common problem with an incidence of 1.8-5.6 per 1000 population. Physiotherapy, anti-inflammatories, corticosteroid injections and surgery have all been described in the management of GTPS, with limited, temporal success. Extracorporeal shockwave therapy (ESWT) has been proposed as a potential non-invasive management option for this difficult presentation. METHOD We ran a prospective, 2-arm, single-blinded, randomised control trial comparing focused shockwave therapy (f-ESWT) to an ultrasound guided corticosteroid injection. Primary outcome measure was the visual analogue pain score. Secondary outcome measures included the Harris Hip Score (HHS) and Trendelenburg test for function; SF-36 for quality of life (QoL); and a Likert scale question for subjective assessment of symptom improvement. RESULTS 104 patients (10 males and 94 females), of mean age 61.5 years were recruited. 53 were randomised to receive ESWT and 51 to receive an image-guided injection. 11 patients were lost to follow-up. There were no significant differences in baseline scores between groups.At 3 months, pain, function and QoL scores had improved in both groups but were not statistically significant. The Trendelenburg test was significantly improved in the f-ESWT group with 80% patients being negative compared to 20% at baseline (p < 0.001).At 12 months, across all outcomes, the ESWT group had significantly improved scores compared to the injection group; VAS 37.1 versus 55.0 (p = 0.007, 95% confidence interval [CI], 6.3-30.8), HHS 69.7 versus 57.5 (p = 0.002, 95% CI, -20.0 to -4.6) and SF-36 52.4 versus 47.7 (p = 0.048, 95% CI, -9.31 to -0.04). The improvement in Trendelenburg test was maintained in the ESWT group, but the injection group had reverted to baseline (p < 0.001). CONCLUSIONS We have shown f-ESWT is an effective treatment for patients with GTPS. We would advocate f-ESWT as an effective non-invasive treatment modality for this challenging patient population.Trial Registration No. ISRCTN8338223.

Abstract
INTRODUCTION Greater trochanter pain syndrome (GTPS) is characterized by a persistent and debilitating pain around the greater trochanter. GTPS can be caused by a combination of gluteus medius or minimus tendinopathy, snapping hip or trochanteric bursitis. SOURCE OF DATA Recent published literatures identified from PubMed, EMBASE, Google Scholar, Scopus. AREAS OF AGREEMENT Platelet rich plasma (PRP) and corticosteroids (CCS) injections are useful options to manage symptoms of GTPS. AREAS OF CONTROVERSY Whether PRP leads to superior outcomes compared to CCS injections is unclear. GROWING POINTS A systematic review and meta-analysis comparing PRP versus CCS in the management of GTPS was conducted. AREAS TIMELY FOR DEVELOPING RESEARCH PRP injections are more effective than CCS at approximately 2 years follow-up.

Abstract
Greater trochanteric pain syndrome is a common cause of lateral hip pain, encompassing a spectrum of disorders, including trochanteric bursitis, abductor tendon pathology, and external coxa saltans. Greater trochanteric pain syndrome is primarily a clinical diagnosis, and careful clinical examination is essential for accurate diagnosis and treatment. A thorough history and physical exam may be used to help differentiate greater trochanteric pain syndrome from other common causes of hip pain, including osteoarthritis, femoroacetabular impingement, and lumbar stenosis. Although not required for diagnosis, plain radiographs and magnetic resonance imaging may be useful to exclude alternative pathologies or guide treatment of greater trochanteric pain syndrome. The majority of patients with greater trochanteric pain syndrome respond well to conservative management, including physical therapy, non-steroidal anti-inflammatory drugs, and corticosteroid injections. Operative management is typically indicated in patients with chronic symptoms refractory to conservative therapy. A wide range of surgical options, both open and endoscopic, are available and should be guided by the specific etiology of pain. The purpose of this review is to highlight pertinent clinical and radiographic features used in the diagnosis and management of greater trochanteric pain syndrome. In addition, treatment indications, techniques, and outcomes are described.

Abstract
BACKGROUND The giant haemorrhagic bursitis of the hip joint is a rare clinical condition that requires evidence-based guidelines for adequate diagnosis and management. Usually, this pathology requires conservative treatment; however, when abnormal size or clinical symptoms of compression of the surrounding noble structures are reported, an accurate differential diagnosis is required, in order to exclude other malignant conditions that can be included into differential diagnosis, and a surgical approach should be considered. The purpose of this work is to provide an appropriate description of the diagnostic and therapeutic path, providing an accurate analysis of the possible differential diagnoses. METHODS We report 2 cases of symptomatic haemorrhagic bursitis of the hip joint, confirmed by histological investigation. In both cases, the patients complained a peripheral nerve deficit of a single limb: one patient presented paresthesia of lateral femoral cutaneous nerve while the second peripheral edema due to compression of the proximal venous and lymphatic circulation. RESULTS Both cases were successfully managed by complete surgical excision of the mass, with no recurrence. There were no major complications, but in first case the nerve deficit was permanent. CONCLUSIONS Giant hemorrhagic trochanteric bursitis is a rare condition, but it should be included in the differential diagnosis of soft tissue masses arising from the hip joint. Due to the rarity of this entity, a cautious exclusion process of all plausible differential diagnosis must be undertaken, in order to not miss the possibility of soft-tissue tumors, primarily malignant high-grade sarcomas.

Abstract
Background Gluteal tendinopathy is commonly reported in the literature, but there is a need for a validated magnetic resonance imaging (MRI)-based scoring system to grade the severity of the tendinopathy. Purpose To use intra- and interobserver reliability to validate a new scoring system, the Melbourne Hip MRI (MHIP) score, for assessing the severity of gluteal tendinopathy. Study Design Cohort study (diagnosis); Level of evidence, 3. Methods The MHIP score assesses gluteal tendinopathy according to each 1 of 5 categories: (1) extent of tendon pathology (maximum 5 points); (2) muscle atrophy (maximum 4 points); (3) trochanteric bursitis (maximum 4 points); (4) cortical irregularity (maximum 3 points); and (5) bone marrow edema (maximum 1 point), with an overall range of 0 to 17 (most severe). A total of 41 deidentified MRI scans from 40 patients diagnosed with gluteal tendinopathy (mean baseline age, 57.44 ± 25.26 years; 4 male, 36 female) were read and graded according to MHIP criteria by 2 experienced musculoskeletal radiologists. The radiologists were blinded to previous reports, and the scans were read twice within a 2-month period. Statistical analysis using the intraclass correlation coefficient (ICC) was used to determine intra- and interobserver reliability and mean/range for the MHIP scores. Results Of a total of 123 readings, the mean MHIP score (±SD) was 3.93 ± 2.24 (range, 0-17 points). The MHIP score demonstrated excellent reliability for determining the severity of gluteal tendinopathy on MRI. The ICC for intra- and interobserver reliability was 0.81 (95% CI, 0.67-0.89) and 0.78 (95% CI, 0.62-0.87), respectively. Conclusion The MHIP score had excellent intra- and interobserver reliability in scoring gluteal tendinopathy. This score allows gluteal tendon pathology to be graded prior to treatment and to be used for standardized comparisons between results in future research undertaking radiological review of gluteal tendinopathy.

Abstract
BACKGROUND Our study aimed at quantifying the overall incidence of lateral trochanteric pain (LTP) following total hip arthroplasty (THA) and risk based on surgical approach. The success of conservative treatment and potential risk factors for failure of conservative treatment were evaluated. METHODS This is a retrospective review of patients who underwent primary THA between 2010 and 2019 and had a postoperative diagnosis of ipsilateral LTP. Chart review revealed patient demographics/comorbidities, preoperative diagnosis, surgical approach, femoral components, and nonoperative treatment modalities. Radiographic analysis was performed to measure leg length discrepancy, femoral offset, and femoral head lateralization. RESULTS The incidence of LTP following primary THA was 1.70% (573/33,761) with an average time to diagnosis of 27.3 months. The direct anterior approach demonstrated the highest risk and the direct lateral demonstrated the lowest risk for LTP (P < .001). Also, 82.4% (472/573) were diagnosed greater than 6 months postoperatively (P < .001). Of 573 patients, 95 (16.6%) were treated with physical therapy, home exercises, or oral medications with a success rate of 96.8% (92/95). Remaining 478 (83.4%) were treated with corticosteroid injection (CSI). And 89.5% (428/478) of the CSI cohort demonstrated clinical improvement with 3 or less CSIs. Risk factors for failure of conservative treatment were depression (P = .034), kidney disease (P = .040), and osteoporosis (P = .007). CONCLUSION Postoperative LTP after THA is rare with an incidence of 1.70%. The direct anterior approach presented higher risk of LTP. Non-CSI modalities and CSIs were both successful treatment options. In patients with depression, kidney disease, and osteoporosis, conservative treatment may be less efficacious.

Abstract
BACKGROUND A previously published trial showed that patients with chronic gluteal tendinopathy achieved greater clinical improvement at 12 weeks when treated with a single platelet-rich plasma (PRP) injection than those treated with a single corticosteroid injection (CSI). PURPOSE This follow-up study was conducted to determine whether there would be a sustained long-term difference in the modified Harris Hip Score (mHHS) at 2 years for a leucocyte-rich PRP (LR-PRP) injection in the treatment of chronic gluteal tendinopathy. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS This trial included 80 patients randomized 1:1 to receive LR-PRP or CSI intratendinously under ultrasound guidance. Patients had a mean age of 60 years, a 9:1 ratio of women to men, a mean body mass index of 27, and a mean length of symptoms >15 months. No patients had full-thickness tears of the gluteal tendons. An open-labeled extension allowed patients to receive crossover treatment after 3 months. The main outcome measure was the mHHS. RESULTS The mean mHHS improved significantly at 12 weeks in the PRP group (74.05; SD, 13.92) as compared with the CSI group (67.13; SD, 16.04) ( P = .048). At 24 weeks, the LR-PRP group (77.60; SD, 11.88) improved further than the CSI group (65.72; SD, 15.28; P = .0003). Twenty-seven patients were deemed to have failed the CSI treatment at 16 to 24 weeks, with an exit score of 59.22 (SD, 11.54), and then had treatment with LR-PRP. The crossover group improved with the LR-PRP: from 59.22 (SD, 11.22) at baseline to 75.55 (SD, 16.05) at 12 weeks, 77.69 (SD, 15.30) at 24 weeks, and 77.53 (SD, 14.54) at 104 weeks. The LR-PRP group retained 38 of 39 patients to 52 weeks and continued to improve. Their baseline scores of 53.77 (SD, 12.08) improved to 82.59 (SD, 9.71) at 104 weeks ( P < .0001). CONCLUSION Among patients with chronic gluteal tendinopathy and a length of symptoms >15 months, a single intratendinous LR-PRP injection performed under ultrasound guidance results in greater improvement in pain and function than a single CSI. The improvement after LR-PRP injection is sustained at 2 years, whereas the improvement from a CSI is maximal at 6 weeks and not maintained beyond 24 weeks.

Abstract
BACKGROUND Trochanteric bursitis (TB) remains a common complication after total hip arthroplasty (THA), with an incidence between 3% and 17%, depending on the surgical approach, with the posterior approach (PA) being relatively protective compared to the lateral approach. The purposes of this study were to determine the incidence of TB after primary THA, identify potential risk factors for TB, and examine the utility of different modes of treatment. METHODS Retrospective cohort data of 990 primary THAs performed in a single institution, including 613 PAs and 377 direct anterior approaches (DAAs), were analyzed. Data abstracted included demographic data, operative diagnosis, comorbidities, radiographic assessment, and other specific predictors of interest that were compared between patients diagnosed with TB following THA and controls. RESULTS The incidence of TB following primary THA was 5.4% (54/990) for the entire cohort. The incidence did not differ significantly between the PA and DAA (5% vs 6.1%, respectively; P = .47). Charlson comorbidity index and American Society of Anesthesiology did not differ significantly in the TB group. Lumbar spinal stenosis and history of past smoking were significantly more common in patients who developed TB (P = .03, P = .01, respectively), but did not continue to be significant risk factors on multivariate analysis. All patients were treated nonoperatively by the time of final follow-up. Seventy-four percent required a local steroid injection and 30% required treatment with more than one modality. CONCLUSION The occurrence of TB is not influenced by the surgical approach (PA or DAA), and could not be predicted by specific comorbidities or radiographic measurements. However, it can be effectively treated conservatively in most cases.

Abstract
Study Design Prospective, randomized, partially blinded. Background Greater trochanteric pain syndrome (GTPS) is the current terminology for what was once called greater trochanteric or subgluteal bursitis. Cortisone (corticosteroid) injection into the lateral hip has traditionally been the accepted treatment for this condition; however, the effectiveness of injecting the bursa with steroids is increasingly being questioned. An equally effective treatment with fewer adverse side effects would be beneficial. Objective To investigate whether administration of dry needling (DN) is noninferior to cortisone injection in reducing lateral hip pain and improving function in patients with GTPS. Methods Forty-three participants (50 hips observed), all with GTPS, were randomly assigned to a group receiving cortisone injection or DN. Treatments were administered over 6 weeks, and clinical outcomes were collected at baseline and at 1, 3, and 6 weeks. The primary outcome measure was the numeric pain-rating scale (0-10). The secondary outcome measure was the Patient-Specific Functional Scale (0-10). Medication intake for pain was collected as a tertiary outcome. Results Baseline characteristics were similar between groups. A noninferiority test for a repeated-measures design for pain and averaged function scores at 6 weeks (with a noninferiority margin of 1.5 for both outcomes) indicated noninferiority of DN versus cortisone injection (both, P<.01). Medication usage (P = .74) was not different between groups at the same time point. No adverse side effects were reported. Conclusion Cortisone injections for GTPS did not provide greater pain relief or reduction in functional limitations than DN. Our data suggest that DN is a noninferior treatment alternative to cortisone injections in this patient population. Level of Evidence Therapy, level 1b.

Abstract
Synopsis Gluteal tendinopathy is now believed to be the primary local source of lateral hip pain, or greater trochanteric pain syndrome, previously referred to as trochanteric bursitis. This condition is prevalent, particularly among postmenopausal women, and has a considerable negative influence on quality of life. Improved prognosis and outcomes in the future for those with gluteal tendinopathy will be underpinned by advances in diagnostic testing, a clearer understanding of risk factors and comorbidities, and evidence-based management programs. High-quality studies that meet these requirements are still lacking. This clinical commentary provides direction to assist the clinician with assessment and management of the patient with gluteal tendinopathy, based on currently limited available evidence on this condition and the wider tendon literature and on the combined clinical experience of the authors.

Abstract
CASE REPORT differential diagnosis and clinical decision making. BACKGROUND AND PURPOSE Young adults with lateral hip pain are often referred to physical therapy (PT). A thorough examination is required to obtain a diagnosis and guide management. The purpose of this case report is to describe the physical therapist's differential diagnostic process and clinical decision making for a subject with the referring diagnosis of trochanteric bursitis. CASE DESCRIPTION A 29-year-old female presented to PT with limited sitting and running tolerance secondary to right lateral hip pain. Her symptoms began three months prior when she abruptly changed her running intensity and frequency of weight bearing activities, including running and low impact plyometrics for the lower extremity. Physical examination revealed a positive Trendelenburg sign, manual muscle test that was weak and painless of the right hip abductors, and pain elicited when performing a vertical hop on a concrete surface (+single leg hop test), but pain-free when performing the same single leg hop on a foam surface. Examination findings warranted discussion with the referring physician for further diagnostic imaging. OUTCOMES Magnetic resonance imaging revealed a focus of edema in the posterior acetabulum, suspicious for an acetabular stress fracture. The subject was subsequently diagnosed with an acetabular stress fracture and restricted from running and plyometrics for four weeks. DISCUSSION Thorough examination and appropriate clinical decision making by the physical therapist at the initial examination led to the diagnosis of an acetabular stress fracture in this subject. Clinicians must be aware of symptoms and signs which place the subject at risk for stress fracture for timely referral and management. LEVEL OF EVIDENCE 4.

Abstract
BACKGROUND AND PURPOSE Chronic lateral hip and thigh pain is regularly treated by the physical therapist. Many issues can cause pain in this region, and trigger points may contribute to pain. Dry Needling (DN) is an intervention used by physical therapists where a monofilament needle is inserted into soft tissue to reduce pain thereby facilitating return to prior level of function. The purpose of this case series is to report the outcomes of DN and conventional physical therapy as a treatment intervention for subjects with chronic lateral hip and thigh pain. CASE DESCRIPTIONS Four subjects with chronic lateral hip and thigh pain attended between four and eight sixty-minute sessions of dry needling and stretching/ strengthening activities over a four to eight week intervention course. Outcomes were tested at baseline and upon completion of therapy. A long-term follow up averaging 12.25 months (range 3 to 20 months) was also performed. The outcome measures included the Visual Analog Scale (VAS) and the Lower Extremity Functional Scale (LEFS). OUTCOMES The LEFS and VAS indicated clinically meaningful improvements in disability and pain in the short term and upon long term follow up for each subject. The LEFS(mean) for the four subjects improved from 50.75 at baseline to 66.75 at the completion of treatment. At long-term follow-up, the LEFS(mean) was 65.50. Each subject met the minimal clinically important difference (MCID) and minimal detectable change (MDC) for the LEFS and the VAS. The VAS was broken down into best (VAS(B)), current (VAS(C)), and worst (VAS(W)) rated pain levels and averaged between the four subjects. The VAS(B) improved from 20 mm at the initial assessment to 0 mm upon completion of the intervention duration. The VAS(C) improved from 25.75 mm to 11.75 mm, and the VAS(W) improved from 85 mm to 32.5 mm. At the long-term follow up (average 12.25 months), the VAS(B), VAS(C), and VAS(W) scores were 0 mm, 14.58 mm, and 43.75 mm respectively. DISCUSSION Clinically meaningful improvements in pain and disability were noted. Subjects reported improved sleep and functional mobility, which were commensurate with their different age ranges and initial reported limitations in mobility. The results of this case series show promising outcomes for the use of dry needling in the treatment of chronic lateral hip and thigh pain. Further controlled clinical trials are recommended to determine the effectiveness of adding dry needling as compared to other interventions for chronic lateral hip and thigh pain.

Abstract
BACKGROUND AND PURPOSE Lateral thigh pain, commonly referred to as greater trochanteric pain syndrome (GTPS) and/ or iliotibial band syndrome (ITBS) is commonly treated by the physical therapist. Lateral thigh pain is commonly treated by the physical therapist. The sources of lateral thigh pain are commonly attributed to GTPS and/ or ITBS though various pathologies may contribute to this pain, of which trigger points (TrPs) may be an etiology. Dry needling (DN) is an intervention utilized by physical therapists where a monofilament needle is inserted into soft tissue in order to reduce pain to improve range of motion/ motor control dysfunction. This can assist with facilitation of return to prior level of function. The purpose of this case report is to report the outcomes of a patient with lateral hip and thigh pain treated with DN as a primary intervention strategy. CASE DESCRIPTION The subject was an active 78-year-old female recreational walker who was referred to physical therapy for chronic left lateral hip and thigh pain of greater than one-year duration without a clear mechanism of injury. She had a history of previous physical therapy treatment for the same condition, and previous therapeutic intervention strategies were effective for approximately two to three months duration prior to return of pain symptoms. Physical examination supported a diagnosis of GTPS/ ITBS. Subjective reports denoted sleep deficit due to pain lying on the left side at night and difficulty walking more than five minutes. Objective findings included decreased strength of the hip musculature and reproduction of pain symptoms upon flat palpation in specific locations throughout the lateral hip and thigh regions. She was treated for eight weeks using only DN to determine the effectiveness of DN as a primary intervention strategy, as previous physical therapy interventions were inconsistent and were only beneficial in the short-term. OUTCOMES Clinically meaningful improvements were noted in disability and pain, as measured by the Lower Extremity Functional Scale and Quadruple Visual Analog Scale. Improvement in strength was not an objective measure being assessed, however, lower extremity strength improvement was noted upon final physical examination. This case report focused on pain reduction for improved function rather than strength improvement. Improvements in pain and disability were subjectively reported. The subject was able to lie on her left side at night, which improved her ability to sleep. She was also able to tolerate walking approximately twenty to thirty minutes for improved community ambulation needs. DISCUSSION This case report presents promising outcomes for the use of DN in the treatment of chronic lateral hip and thigh pain. Further research is recommended to determine if DN is clinically beneficial independent of other therapeutic interventions such as exercise, myofascial release/ massage, non-thrust mobilization, or manipulation.

Abstract
Tuberculous trochanteric bursitis (TTB) is a rare condition that accounts for 1% of musculoskeletal tuberculosis cases. Extrapulmonary TB is usually diagnosed late because of reduced diagnostic suspicion, particularly in the absence of signs of systemic infection. Herein, we report a case of right hip pain that was misdiagnosed as ankylosing spondylitis. The patient had a history of inflammatory back pain with morning stiffness. However, HLA-B27 was negative. Sacroiliac magnetic resonance imaging (MRI) revealed a giant multiloculated collection (27×16×10 cm). Percutaneous drainage was performed and Mycobacterium tuberculosis was observed in fluid culture. The patient was treated by drainage along with antituberculosis therapy. After 1 year of antituberculosis therapy, control MRI revealed total resolution of the large fluid collection. It is important to emphasize that fever or general symptoms are absent in patients with TTB, as observed in the present case. In endemic countries, TTB should be kept in mind in the differential diagnosis of a patient presenting with chronic hip pain without fever, weight loss, and constitutional symptoms.

Abstract
Musculoskeletal injury causes pain and when chronic can affect mental health, employment and quality of life. This study examined work participation, function and quality of life in people with greater trochanteric pain syndrome (GTPS, n=42), severe hip osteoarthritis (OA, n=20) and an asymptomatic group (ASC, n=23). No differences were found between the symptomatic groups on key measures, both were more affected than the ASC group, they had lower quality of life score (p<0.001), Harris Hip Score (p<0.001) and higher Oswestry Disability Index (p<0.001). Participants with GTPS were the least likely to be in fulltime work (prob. GTPS=0.29; OA=0.52; and ASC=0.68). GTPS appears to confer levels of disability and quality of life similar to levels associated with end stage hip OA.

Abstract
OBJECTIVE Trochanteric bursitis (TB) is a self-limiting disorder in the majority of patients and typically responds to conservative measures. However, multiple courses of nonoperative treatment or surgical intervention may be necessary in refractory cases. The purpose of this systematic review was to evaluate the efficacy of the treatment of TB. DATA SOURCES A literature search in the PubMed, MEDLINE, CINAHL, and ISI Web of Knowledge databases was performed for all English language studies up to April 2010. Terms combined in a Boolean search were greater trochanteric pain syndrome, trochanteric bursitis, trochanteric, bursitis, surgery, therapy, drug therapy, physical therapy, rehabilitation, injection, Z-plasty, Z-lengthening, aspiration, bursectomy, bursoscopy, osteotomy, and tendon repair. STUDY SELECTION All studies directly involving the treatment of TB were reviewed by 2 authors and selected for further analysis. Expert opinion and review articles were excluded, as well as case series with fewer than 5 patients. Twenty-four articles were identified. According to the system described by Wright et al, 2 studies, each with multiple arms, qualified as level I evidence, 1 as level II, 1 as level III, and the rest as level IV. More than 950 cases were included. DATA EXTRACTION The authors extracted data regarding the type of intervention, level of evidence, mean age of patients, patient gender, number of hips in the study, symptom duration before the study, mean number of injections before the study, prior hip surgeries, patient satisfaction, length of follow-up, baseline scores, and follow-up scores for the visual analog scale (VAS) and Harris Hip Scores (HHS). DATA SYNTHESIS Symptom resolution and the ability to return to activity ranged from 49% to 100% with corticosteroid injection as the primary treatment modality with and without multimodal conservative therapy. Two comparative studies (levels II and III) found low-energy shock-wave therapy (SWT) to be superior to other nonoperative modalities. Multiple surgical options for persistent TB have been reported, including bursectomy (n = 2), longitudinal release of the iliotibial band (n = 2), proximal or distal Z-plasty (n = 4), osteotomy (n = 1), and repair of gluteus medius tears (n = 4). CONCLUSIONS Efficacy among surgical techniques varied depending on the clinical outcome measure, but all were superior to corticosteroid therapy and physical therapy according to the VAS and HHS in both comparison studies and between studies. This systematic review found that traditional nonoperative treatment helped most patients, SWT was a good alternative, and surgery was effective in refractory cases.
