Greater trochanteric pain syndrome (GTPS) is a common and disabling hip condition. Hypermobility has been suggested as a possible cause of GTPS. The purpose of this study was to report the prevalence of hypermobility and to investigate its impact on hip-related function and awareness in patients with GTPS. This cross-sectional study was based on a cohort of patients diagnosed with GTPS in the 2013–2015 period. Hypermobility was investigated with the Beighton Score and defined by a cut-off score ≥5. Data on patients' current hip function and awareness were collected with the questionnaires the Copenhagen Hip and Groin Outcome Score and the Forgotten Joint Score. A total of 612 patients with GTPS were identified based on the diagnosis system; out of those, 390 patients were assessed for eligibility, and 145 (37%) were included. The prevalence of hypermobility within this cohort was estimated to be 11% (95% confidence interval (CI): 3–26%) for males and 25% (95% CI: 17–34%) for females. No significant association was found between hypermobility and self- reported hip function and awareness. We recommend that future studies of GTPS will include hypermobility and investigate the consequences of hypermobility among patients with GTPS

Introduction. Greater trochanteric pain syndrome (GTPS) is a common and disabling condition characterised by pain and tenderness at or around the trochanteric area. Extracorporeal shockwave therapy (ESWT) has been described as a method of treatment. The National Institute for Clinical Excellence (NICE, UK) guidance suggests a possible benefit but with limited evidence. Materials and Methods. We retrospectively identified 71 consecutive patients who underwent ESWT for refractory GTPS over a period of 16 months. The diagnosis was made clinically. ESWT was offered to patients with refractory symptoms despite conservative treatment. Telephone interviews were used to collect data including pain scores (0–10), change in symptoms, discomfort of the procedure, and complications. Results. Fifty-nine patients (83%) were followed up. The mean time to follow up was 8 months (3 to 19). The mean age was 59 (29 to 88) with 86% females. Two-thirds had improvement in their symptoms with a significant drop of 6 points in their pain score (p<0.05); however, symptoms recurred in 60% at a mean of 3.7 months. Most patients (60%) had mild or no discomfort from the treatment. Two patients (3.3%) could not tolerate the treatment. One complication was reported; an exacerbation of sciatica symptoms which settled spontaneously. Conclusion. This study shows an improvement in the symptoms of 67% of patients with refractory GTPS, for up to 15 months, but with frequent relapsed. Further research is required to confirm whether MRI may be useful in selecting patients for ESWT

Background. Greater trochanteric pain syndrome (GTPS) is a common problem affecting 10–25% of the population. Physiotherapy, anti-inflammatories, corticosteroid injections and surgery have all been described in the management of GTPS, all with limited, temporal success. Extracorporeal shockwave therapy (ESWT) has been proposed as a potential management option for this difficult presentation. Method. We ran a prospective, 2 arm, single blinded, randomised control trial comparing focused shockwave therapy to an ultrasound guided corticosteroid injection. The primary outcome measure was the visual analogue pain score. Secondary outcome measures included the Harris hip score and Trendelenburg test for function; the SF-36 for quality of life (QoL); and a Likert scale question for a 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. Baseline scores were equal between the groups. At 3 months, pain, function and QoL scores had improved in both groups. The Trendelenburg test was significantly improved in the ESWT group with 80% patients being negative compared to 80% positive at baseline (p<0.001). At 12 months, the improvement in Trendelenburg test was maintained in the ESWT group, but the injection group had reverted to baseline. Across all outcomes, the ESWT group had significantly improved scores compared to the injection group; VAS 3.71 versus 5.50 (p=0.007, 95% confidence interval 0.63 to 3.08), HHS 69.7 vs 57.5 (p=0.002, 95% confidence interval −20.0to −4.6) and SF-36 52.4 vs 47.7 (p=0.048, 95% confidence interval −9.31 to −0.04). Conclusions. We have shown focused ESWT is an effective treatment for patients with GTPS. We hope to advocate ESWT as an effective non-invasive treatment modality for this challenging patient population

Greater trochanteric pain syndrome is a painful condition characterised by pain around the greater trochanter usually affecting middle-aged women. The majority of patients will improve with conservative management such as physiotherapy and non-steroidal anti-inflammatory drugs (NSAIDs); however, if this fails then more invasive treatments including corticosteroids and surgery may be required. Platelet-rich plasma (PRP) is an autologous blood product, which has a higher concentration of growth factors postulated to provide enhanced healing and anti-inflammatory properties. The Hip Injections PRP Vs Placebo (HIPPO) trial aims to assess the ability of ultrasound-guided PRP injections to improve symptoms and function in patients with GTPS. 64 patients were enrolled and randomised to either the PRP or placebo (normal saline) treatment arm. Two patients decided to drop out of the trial. Clinical outcomes in both groups were evaluated and compared using the International Hip Outcome Tool-12 (iHOT12), Visual Analogue Scale (VAS) of pain, the modified Harris Hip Score (mHHS) and the presence or absence of complications at 3 and six months. The level of significance was set at p<0.05. Both groups received physiotherapy after the injections. The mean age was 57.5. There were 6 males and 56 females with M:F ratio of 1:9.3. Both groups were similar in terms of demography and preoperative scores. The iHOT12 score improved from 28.23 to 45.42 at three-months and decreased slightly to 42.44 at six-months in the Placebo group. The iHOT12 in the PRP group improved from 35.51 to 44.47 at three-months and decreased to 39.78 at six-months. Both groups showed improved VAS and mHHS at three-months compared to the baseline with no statistically significant difference between the two groups (p >0.05). The scores decreased at six-months however remained above the baseline. No complications were reported. Gender and age had no effect on outcomes. Both groups similarly improved from baseline. Physiotherapy can be considered as an important factor in patients' treatment. Further research should be conducted to investigate the role of physiotherapy in the treatment of GTPS

Greater trochanteric pain syndrome (GTPS) is common, yet the impact on function and quality of life has not been measured. The aim of this study was to quantify the impact on function and quality of life, comparing the results to people with severe hip osteoarthritis and an asymptomatic control group. Forty two people with GTPS – including 11 not actively seeking treatment and 11 seeking surgical treatment, 20 with severe hip osteoarthritis (OA), and 23 age and sex matched asymptomatic participants (ASC) where recruited from public and private hospitals, and the community. Upon confirming meeting inclusion and exclusion criteria participants were interviewed. Exclusion criteria included lumbar nerve root signs; inflammatory, neoplastic and metabolic disorders. Measured used were the Harris hip score (HHS); the Oswestry disability index (ODI); the Australian quality of life instrument (AQoL); the Functional co-morbidity index (FCI); and fulltime work assessments. No difference was found between the GTPS and the OA group on the HHS, ODI, AQoL or the FCI measures. Both symptomatic groups were significantly more disabled than the ASC group on the HHS and ODI (p<0.001). The GTPS and OA groups had lower AQoL than the ASC group (p<0.001); and higher FCI results than the ASC group (GTPS vs ASC, p=0.005; OA vs ASC, p=0.019). GTPS participants were least likely to be in full time work; full time work participation probability (95% C.I.): GTPS Prob=0.288 (0.160 to 0.463), OA Prob= 0.518 (0.273 to 0.753); ASC group of Prob=0.676 (0.439 to 0.847). People with GTPS have similar levels of pain, disability and quality of life, but are less likely to be in full time employment than people with severe hip OA which puts them at risk of economic hardship. Research on conservative and surgical treatments should measure pain, disability and work participation

Aim

To identify differences in hip muscle strength, knee valgus during a single leg squat (SLS),and function between subjects with Greater Trochanter Pain Syndrome (GTPS) and healthy(H) subjects. To determine associations between pain, function, hip strength and SLS in GPTS subjects. Study Design: Observational study of 14 (3 male 11 female) PFP patients (mean symptom duration 17 months), matched for age height and weight with 14 healthy (H) subjects, All subjects fulfilled specific inclusion and exclusion criteria. Appropriate Ethical approval was obtained. Measures for both groups were Knee valgus angle during SLS using 2D motion capture and SiliconCoach software for measurement of knee valgus angles, hip abduction, internal and external rotation muscle strength using hand held dynamometry, visual analogue scale for pain. Lower Extremity Functional Scale (LEFS). All measures were taken on the affected leg for GPTS subjects and matched for the equivalent leg in healthy group. Strength was reported as a percentage of body weight. SiliconCoach was reliable for intra-rater reliability of knee valgus angle (ICC.996).

31 patients, between the ages of 59 and 74 years, were referred to one onrthopaedic consultant as trochanteric bursitis. All were females. Of these 7 patients were diagnosed as osteoarthritis of the hip or underwent further investigations for spinal conditions. 24 patients were clinically diagnosed as trochanteric bursitis. All these patients had ultrasound examination of the hips by a radiologist with a special interest in musculoskeletal diseases. Except for one patient the rest had either gluteus medius inflammation or tears with or without involvement of gluteus minimus. All these patients with positive findings had 80mg of depomedrone injection under USG guidance. At 6 weeks follow up 21 had complete relief of symptoms. 4 had recurrence of symptoms at 3 months when they had another dose of depomedrone und USG guidance. At one year 18 were free of symptoms and the 3 with some recurrence of symptoms did not want any intervention. Discussion: Etiology of greater trochanteric pain syndrome has been a source of considerable debate. Empirical treatment with ‘blind’ steroid injection is the usual course of action. In unresolving trochanteric bursitis excision of trochanteric bursa has been advocated. Gluteus medius and minimus tears have been referred to as rotator cuff tears of the hip (1). Our study shows an association between trochanteric bursitis and ‘rotator cuff tears of hip’. Ultrasound guided steroid injection can give a better success rate of ‘hitting the right spot’. Further investigations are required to identify whether this association could be a cause and effect relationship

Severe and recalcitrant Greater Trochanteric Pain Syndrome (GTPS), previously known as Trochanteric bursitis, has been associated with torn gluteal tendons. The aim of this study was to assess the physical, functional and quality of life outcomes of combined bursectomy and gluteal tendon reconstructive surgery. 24 patients underwent combined bursectomy and gluteal tendon reconstruction under one surgeon. They were contacted by mail, email, and telephone. 16 were available for examination, two had revision surgery, one had interview only, one moved interstate, one declined and three were lost to follow up. An independent standardised assessment was undertaken. Hip muscle strength was measured by hand-held dynamometry. Trendelenburg sign was measured according to Hard-castle’s protocol and by observing gait. Functional and quality of life measures were assessed via the Harris Hip Score and the Oswestry Disability scale. Pain and satisfaction was measured via a 10cm visual analogue scale. All patients were female. The mean time from surgery was 18.9 months +/− 8.50. 10 had right sided surgery. The two patients who had revision surgery are not included in this data. Strength of hip abduction was weaker on the ipsilateral side (p< =.05). External rotation appeared to be weaker, however this was not statistically significant. Hardcastle’s single leg standing Trendelenburg sign was shorter on the ipsilateral side (16.3secs +/− 12.3 vs 22.1secs +/− 10.1, p< =.05). Five patients had an ipsilateral Trendelenburg gait, two had a contralateral Trendelen-burg gait. The mean recalled preoperative pain score was 67.73 +/− 31.51 out of 100. The mean post operative score was 14.44 +/− 16.1 (p< =.0005). Patient satisfaction with the results of surgery was rated at 80.7 +/−17.69, out of 100. With regard to function, the mean post operative Harris hip score was 70.9 +/− 25.73 out of 91, and the Oswestry disability score was 15.5 +/− 11.39, out of 100 where a low score indicates better outcome. Combined bursectomy and gluteal tendon reconstruction appears to be an effective procedure for the relief of pain in patients with recalcitrant GTPS in most patients. High patient satisfaction levels suggest that function and quality of life are improved following surgery. A prospective longitudinal study has commenced to verify these results

Aims

Iliopsoas impingement occurs in 4% to 30% of patients after undergoing total hip arthroplasty (THA). Despite a relatively high incidence, there are few attempts at modelling impingement between the iliopsoas and acetabular component, and no attempts at modelling this in a representative cohort of subjects. The purpose of this study was to develop a novel computational model for quantifying the impingement between the iliopsoas and acetabular component and validate its utility in a case-controlled investigation.

The aim of this review is to evaluate the current available literature evidencing on peri-articular hip endoscopy (the third compartment). A comprehensive approach has been set on reports dealing with endoscopic surgery for recalcitrant trochanteric bursitis, snapping hip (or coxa-saltans; external and internal), gluteus medius and minimus tears and endoscopy (or arthroscopy) after total hip arthroplasty. This information can be used to trigger further research, innovation and education in extra-articular hip endoscopy.
