High prevalence of greater trochanteric pain syndrome among patients presenting to spine clinic for evaluation of degenerative lumbar pathologies

The role of the greater trochanter pain syndrome in lumbar degenerative disc disease surgery

PURPOSE

Greater trochanter pain syndrome (GTPS) is highly discussed during spine surgeons, accompanies lumbar pain and complicates differential diagnosis. The aim is to raise awareness among physicians and demonstrate the lumbar spine degenerative diseases (LSDD) association with GTPS.

METHODS

A retro-prospective analysis enrolled 172 patients with LSDD with GTPS signs. Group I - retrospective (n = 112), group II - prospective (n = 60). Patients of group II with the confirmed diagnosis clinically and by the ultrasound recieved a GCS injection (Betamethasone 2 mg\ml + 5 mg\ml - 1.0). Also the VAS, X-ray and SPSS Statistics package were used.

RESULTS

112 patients in group I, 89 (79.5%) had increased pain in the hip early postOp to 7.8 points by VAS. All patients required trigger point injections of GCS and 68 (77%) received a repeat injection. 76 from 112 patients were tracked for long-term results, and recurrence of GTPS was detected in five people who treated conservatively for three months without dynamics. They were identified GTPS by ultrasound. During the injection, 39 from 43 (90%) patients noted pain reduction to 2.1 by VAS, but symptoms of radiculopathy or spinal stenosis persisted. Two patients (5%) did not note any changes. Two patients (5%) noted complete pain regression and refused the surgery.

CONCLUSION

Timely detection of GTPS among spinal surgeons influences tactics and, in some cases, allows one to avoid unnecessary surgical interventions. In turn, ignoring the symptoms of GTPS in the preoperative period can lead to pain intensification in the greater trochanter after surgery for degenerative diseases of the spine.

Low-dose radiotherapy for greater trochanteric pain syndrome-a single-centre analysis

PURPOSE

To determine predictive factors associated with a good response (GR) to and efficacy of low-dose radiotherapy (LDRT) in patients with greater trochanteric pain syndrome (GTPS).

METHODS

Patients with GTPS were irradiated on a linear accelerator with 0.5-1.0 Gy per fraction to a total dose of 3.0-4.0 Gy per series. The endpoint was subjective good response (GR) to treatment 2 months after completion of the last LDRT series, defined as complete pain relief or marked improvement assessed using the von Pannewitz score. A positive response to steroid injection (SI) was defined as pain relief of at least 7 days. Patient and treatment-related characteristics were evaluated with respect to LDRT outcomes.

RESULTS

Outcomes were assessed for 71 peritrochanteric spaces (PTSs; 65 patients, 48 females, with mean age of 63 [44-91] years). Prior SI had been given to 55 (77%) PTSs and 40 PTSs received two series of LDRT. Two months after completion of LDRT, GR was reported in 42 PTSs (59%). Two series of LDRT provided a significantly higher rate of GR than one series (72.5 vs. 42% PTSs, p = 0.015). Temporary pain relief after prior SI predicted GR to LDRT compared with PTSs which had not responded to SI (73 vs. 28% PTSs, p = 0.001). A regional structural abnormality, present in 34 PTSs (48%), was associated with a reduction of GR to LDRT (44 vs. 73% PTSs, p = 0.017).

CONCLUSION

LDRT is an effective treatment for GTPS. Administration of two LDRT series, prior response to SI, and absence of structural abnormalities may predict significantly better treatment outcomes.

Intraoperative Classification System Yields Favorable Outcomes for Patients Treated Surgically for Greater Trochanteric Pain Syndrome

PURPOSE

To use a prospectively collected database to internally validate a previously published intraoperative classification system by determining its utility in improving patient-reported outcome scores (PROS).

METHODS

Open or endoscopic procedures performed at a single center between February 2008 and March 2018 with minimum 2-year follow-up were reviewed. Patients were prospectively classified intraoperatively as one of five greater trochanteric pain syndrome (GTPS) types according to the Lall GTPS classification system and underwent one of the six following surgical procedures: trochanteric bursectomy (TB, type I); TB with trochanteric micropuncture (type II); endoscopic suture staple repair (type IIIA); endoscopic single row transtendinous repair (type IIIB); open or endoscopic double row repair (type IV); and gluteus maximus/tensor fasciae latae transfers (type V). The following PROS were analyzed to assess the efficacy of treatment and validity of the classification scheme: modified Harris Hip Score (mHHS), Nonarthritic Hip Score, The International Hip Outcome Tool, Hip Outcome Score-Sport-Specific Subscale, and visual analog scale for pain.

RESULTS

In total, 324 patients (287 female, 37 male) underwent surgical management per GTPS classification type: 109 type I; 26 type II; 20 type IIIA; 118 type IIIB; 44 type IV; and 7 type V. The mean age and follow-up time were 51.9 ± 12.5 years and 44.5 ± 20.5 months, respectively. All patients PROS improved from baseline to minimum 2-year follow-up (P < .05). High rates of the minimal clinically important difference for mHHS (70.0-100.0) and Nonarthritic Hip Score (73.1-92.7) and patient acceptable symptomatic state for mHHS (70.0-94.5) and International Hip Outcome Tool (58.1-86.7) were achieved per GTPS type. Patient satisfaction was 7.9/10.

CONCLUSIONS

This validation study supports that the classification system and treatment algorithm for surgical treatment of various GTPS types leads to favorable patient-reported outcomes. These findings provide surgeons with a validated classification system and treatment algorithm to manage peritrochantric pathology diagnosed intraoperatively.

Greater trochanteric pain syndrome: Evaluation and management of a wide spectrum of pathology

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.

Greater trochanteric pain syndrome: predicting who will respond to a local glucocorticoid injection

Objectives: This study aimed to explore whether certain clinical tests or a rapid improvement in lateral hip pain following periarticular injection are predictive of subsequent efficacy of local glucocorticoid (GC) injection in greater trochanteric pain syndrome (GTPS).Method: This secondary analysis of a randomized controlled trial of an injection of GC and local anaesthetic (LA) versus placebo included 44 patients with GTPS. Two subgroups of patients were defined: (i) 30 min responders, reporting a decrease of ≥ 50% of the initial pain at 30 min post-injection; and (ii) positive triple test, presenting a combination of three positive clinical tests (30-second single-leg stance, FABER, and Lequesne). Median level of numeric rating scale for pain at 1 month was the primary outcome. Interaction analysis of treatment effect in the subgroups was performed using a linear regression adjusting for pain at baseline.Results: Sixteen patients (36%) were 30 min responders. In this group, GC treatment was associated with a significant improvement in pain at 1 month compared to non-responders (p = 0.03). The 30 min response was not associated with the use of LA. Positive triple test (22% of patients) was associated with higher pain scores at baseline (p = 0.03). In this group, patients who received placebo had significantly more pain at 1 month than those with the cortisone injection (p = 0.04).Conclusion: Patients with GTPS who present a rapid decrease in pain after periarticular injection, and those who display a combination of three specific clinical tests, are more likely to benefit from an injection with GC and anaesthetic.

Restoration of leg length and offset correlates with trochanteric pain syndrome in total hip arthroplasty

Persistent pain around the greater trochanter is a common complication after total hip arthroplasty. Restoration of biomechanics such as leg length, femoral und acetabular offset is crucial in THA. The purpose of this study was to evaluate postoperative differences of these parameters after THA and to analyze their association to greater trochanteric pain syndrome. Furthermore, we aimed to evaluate the clinical relevance of trochanteric pain syndrome compared to patient reported outcome measures. 3D-CT scans of 90 patients were analyzed after minimalinvasive total hip arthroplasty and leg length, femoral and acetabular offset differences were measured. Clinical evaluation was performed three years after THA regarding the presence of trochanteric pain syndrome and using outcome measures. Furthermore, the patients' expectation were evaluated. Patients with trochanteric pain syndrome showed a higher absolute discrepancy of combined leg length, femoral and acetabular offset restoration compared to the non-operated contralateral side with 11.8 ± 6.0 mm than patients without symptoms in the trochanteric region with 7.8 ± 5.3 mm (p = 0.01). Patients with an absolute deviation of the combined parameters of more than 5 mm complained more frequently about trochanteric symptoms (29.2%, 19/65) than patients with a biomechanical restoration within 5 mm compared to the non-affected contralateral side (8.0%, 2/25, p = 0.03). Clinical outcome measured three years after THA was significantly lower in patients with trochanteric symptoms than without trochanteric pain (p < 0.03). Similarly, fulfillment of patient expectations as measured by THR-Survey was lower in the patients with trochanteric pain (p < 0.005). An exact combined restoration of leg length, acetabular and femoral offset reduces significantly postoperative trochanteric pain syndrome and improves the clinical outcome of the patients.

Does low back pain or leg pain in gluteus medius syndrome contribute to lumbar degenerative disease and hip osteoarthritis and vice versa? A literature review

[Purpose] Gluteus medius syndrome is one of the major causes of back pain or leg pain and is similar to greater trochanteric pain syndrome, which also presents with back pain or leg pain. Greater trochanteric pain syndrome is associated with lumbar degenerative disease and hip osteoarthritis. The objective of this review was to demonstrate gluteus medius syndrome as a disease entity by reviewing relevant articles to elucidate the condition. [Methods] Gluteus medius syndrome was defined as myofascial pain syndrome arising from the gluteus medius. We performed a search of the literature using the following keywords: “back pain”, “leg pain”, “greater trochanteric pain syndrome”, “degenerative lumbar disease”, “hip osteoarthritis”, and “gluteus medius”. We reviewed articles related to gluteus medius syndrome and described the findings in terms of diagnosis and treatment based on the underlying pathology. [Results] A total of 135 articles were included in this review. Gluteus medius syndrome is similar as a disease entity to greater trochanteric pain syndrome, which presents with symptoms of low back pain and leg pain. Gluteus medius syndrome is also related to lumbar degenerative disease, hip osteoarthritis, knee osteoarthritis, and failed back surgery syndrome. [Conclusion] Accurate diagnosis of gluteus medius syndrome and appropriate treatment could possibly improve lumbar degenerative disease and osteoarthritis of the hip and knee, as well as hip-spine syndrome and failed back surgery syndrome.

The ambiguity of sciatica as a clinical diagnosis: A case series

Sciatica as a clinical diagnosis is nonspecific. A diagnosis of sciatica is typically used as a synonym for lumbosacral radiculopathy. However, the differential for combined low back and leg pain is broad, and the etiology can be one several different conditions. The lifetime prevalence of sciatica ranges from 12.2% to 43%, and nonsuccessful outcomes of treatment are prevalent. Nurse practitioners and other primary care clinicians often have minimal training in differential diagnosis of the complex causes of lower back and leg pain, and many lack adequate time per patient encounter to work up these conditions. Differentiating causes of low back and leg pain proves challenging, and inadequate or incomplete diagnoses result in suboptimal outcomes. Chiropractic care availability may lessen demands of primary care with respect to spinal complaints, while simultaneously improving patient outcomes. The authors describe three patients referred from primary care with a clinical diagnosis of sciatica despite differing underlying pathologies. More precise clinical terminology should be used when diagnosing patients with combined low back and leg pain. Nurse practitioners and other clinicians' triage, treat, and determine appropriate referrals for low back and leg pain. Multidisciplinary care including chiropractic may add value in settings where patients with lower back and leg pain are treated.

Greater Trochanteric Pain Syndrome: An Intraoperative Endoscopic Classification System with Pearls to Surgical Techniques and Rehabilitation Protocols

Over the past decade, understanding of disorders compromising greater trochanteric pain syndrome (GTPS) has increased dramatically. Nonsurgical treatment options include physical rehabilitation and activity modification, anti-inflammatory as well as biologic injections into the peritrochanteric compartment, and administration of oral analgesics. Multiple open and endoscopic treatment options exist when nonsurgical management is unsuccessful in patients with refractory lateral-sided hip pain, with or without weakness. No true consensus exists within the literature regarding operative techniques of GTPS or postoperative rehabilitation protocols. We present an endoscopic classification system of GTPS with 5 distinct types, which seems to correlate well with preoperative diagnoses and postoperative rehabilitation protocols. The classification system is intuitive, and the corresponding surgical techniques are reproducible for surgeons treating peritrochanteric pathology. Level of Evidence: I (hip); II (extra-articular, impingement).

A survey of physiotherapy practice (2018) in the United Kingdom for patients with greater trochanteric pain syndrome

PURPOSE

Greater Trochanteric Pain syndrome (GTPS) is a debilitating condition causing lateral hip pain. It affects up to 23.5% of women and 8% of men between 50 and 75 years old. Sufferers report comparable quality of life and functional performance to patients with end stage osteoarthritis of the hip. Understanding of optimal management strategies for GTPS remains limited. Hence, the purpose of this cross-sectional survey was to describe current UK physiotherapy practice so as to understand current practice and inform the systematic development of a physiotherapy intervention.

METHODS

An online survey was developed and distributed via Twitter, the interactive Chartered Society of Physiotherapy website, Musculoskeletal Association of Chartered Physiotherapists and the professional networks of the authors via email. Responses were collected over a four-week period, this was finalised in April 2018.

RESULTS

A total of 409 surveys were submitted; 382 were eligible for use. Nearly all physiotherapists were either somewhat, or very confident diagnosing (372/382; 97.4%) and treating (372/382; 97.4%) patients with GTPS. The management strategies most commonly used were: education on load management (377/381; 98.7%) and self-management strategies (375/381; 98.4%). Strengthening exercises (376/382; 98.4%) were commonly used and targeted to the hip abductors (355/379; 93.7%). Most frequently these exercises were delivered using a combination of home exercise programme (380/380; 100%) and one-to-one exercise sessions (344/377; 91.2%).

CONCLUSION

The data from this large survey highlights that physiotherapists in the UK most commonly use education on load management and self-management strategies, alongside strengthening exercises targeting the hip abductors for patients with GTPS.
