  • the association between psychological factors and Pain exacerbations in Hip osteoarthritis
    Rheumatology, 2020
    Co-Authors: Ben R Metcalf, Kim L Bennell, Yuqing Zhang, Sarah R Robbins, Leticia A Deveza, David J Hunter
    Abstract:

    Objectives To evaluate the association between psychological factors and Pain exacerbations in people with Hip OA. Methods Eligible participants with symptomatic Hip OA were instructed to complete online questionnaires every 10 days over a 90-day follow-up period. In addition, they were required to complete the questionnaire whenever they perceived they were experiencing a Hip Pain exacerbation. Hip Pain exacerbation was defined as an increase of 2 points in Pain intensity compared with baseline on an 11-point numeric rating scale (0-10). The Depression, Anxiety and Stress Scale-21 Items, Positive and Negative Affect Schedule, Pain Catastrophizing Scale and Pain Self-Efficacy Questionnaire were used to evaluate psychological factors. The associations of these with risk of Hip Pain exacerbation were examined by conditional logistic regression. Results Of 252 participants recruited, 131 (52.0%) contributed both case and control period data and were included in the analysis. A significant association was found between Pain Catastrophizing Scale overall score (1 point increase) with Hip Pain exacerbations (odds ratio: 1.07, 95% CI: 1.04, 1.11). An increase of a minimal important change (5.5 points) of Pain Self-Efficacy Questionnaire score was associated with a lower odds of Pain exacerbations (odds ratio: 0.74, 95% CI: 0.65, 0.85). No significant associations were found between Depression, Anxiety and Stress Scale-21 Items or Positive and Negative Affect Schedule scores with Hip Pain exacerbations. Conclusion Both Pain catastrophizing and Pain self-efficacy beliefs were associated with Pain exacerbations in people with Hip OA, but other psychological factors including depression, anxiety and stress or positive and negative affects, were not associated with Pain exacerbations.

  • is heel height associated with Pain exacerbations in Hip osteoarthritis patients results from a case crossover study
    Journal of Clinical Medicine, 2020
    Co-Authors: Ben R Metcalf, Kim L Bennell, Yuqing Zhang, Sarah R Robbins, Leticia A Deveza, David J Hunter, Douglas K Gross, Kathryn Mills
    Abstract:

    The etiology of osteoarthritis (OA) Pain exacerbations is not well understood. The purpose of this study is to evaluate the association of heel height and duration of wearing shoes with higher heels with Pain exacerbations in people with Hip OA. Eligible participants with symptomatic Hip OA were instructed to complete online questionnaires every 10 days over a 90-day follow-up period. They were required to complete the questionnaire whenever they were experiencing Hip Pain exacerbation. Of 252 participants recruited, 137 (54.4%) contributed both case and control period data, and were included in the analysis. Wearing shoes with a heel height ≥ 2.5 cm during the past 24 h was associated with lower odds of Pain exacerbations (OR: 0.54, 95% CI: 0.30 to 0.99). A longer duration (>6 h) of wearing shoes with heel height ≥ 2.5 cm was also associated with a lower risk of Hip Pain exacerbations (p for linear trend = 0.003). Wearing shoes with heel height ≥ 2.5 cm and longer duration in the past 24 h may be protective against Hip Pain exacerbations in people with symptomatic Hip OA. Given the observational study nature, it would be prudent for this to be replicated in an independent data set.

  • role of Hip injury and giving way in Pain exacerbation in Hip osteoarthritis an internet based case crossover study
    Arthritis Care and Research, 2019
    Co-Authors: Joanna Makovey, Ben R Metcalf, Kim L Bennell, Yuqing Zhang, Rebecca Asher, Sarah R Robbins, Leticia A Deveza, David J Hunter
    Abstract:

    OBJECTIVE To evaluate the association between Hip injury/giving way and Hip Pain exacerbations in patients with symptomatic Hip osteoarthritis (OA). METHODS We conducted an internet-based case-crossover study to assess Hip injury and giving way for Hip Pain exacerbation. Eligible participants with symptomatic Hip OA were followed up for 90 days and asked to complete online questionnaires at baseline and 10-day intervals (control periods). They also logged on to the study web site to complete questionnaires for an episode of a Hip Pain exacerbation (case periods) defined as an increase of 2 points in Pain intensity compared with the baseline rating on a numeric rating scale (range 0-10). The relationsHip of Hip injury and giving way to the risk of Pain exacerbation was examined using conditional logistic regression. RESULTS Of 252 patients recruited into the study, we included 133 patients (53%) who provided data from both case and control periods. Hip injury during the last 7 days increased the risk of Hip Pain exacerbation (odds ratio [OR] 2.74 [95% confidence interval (95% CI) 1.62-4.62]). The Hip giving way during the last 2 days was associated with an increased risk of Hip Pain exacerbation (OR 2.10 [95% CI 1.30-3.39]) and showed a significant relationsHip between the number of Hip giving way events and the risk of Hip Pain exacerbations (P < 0.001). CONCLUSION Hip injury and episodes of the Hip giving way were significantly related to Pain exacerbation in patients with symptomatic Hip OA. Methods to prevent exposure to injury may help to reduce the burden of Pain in patients with Hip OA.

  • Sentinel Presentation of Disseminated Blastomyces dermatitidis Infection as Hip Pain in a Young Adult
    2016
    Co-Authors: C. Hamann, Kevin Marberry
    Abstract:

    n young, active patients, the common causes of Hip Pain are multiple and can include muscle strain, contusion, acetabular labral tear, osteochondral injury, sports hernia, snapping Hip, proximal femoral stress fracture, and spinal abnormalities1-3. In most patients, an initial trial of nonoper-ative management is instituted. If Pain persists or is of an unusual presentation, a more extensive diagnostic workup may be used. A thorough clinical evaluation can expedite the di-agnosis of uncommon conditions of the musculoskeletal sys-tem, and the diagnostic evaluation may include magnetic resonance imaging of the pelvis and Hip to evaluate the in-tegrity of the periarticular structures. The case of the patient in the present report illustrates an unusual presentation of dis-seminated Blastomyces dermatitidis infection causing Hip Pain that was diagnosed with magnetic resonance imaging and wa

  • sentinel presentation of disseminated blastomyces dermatitidis infection as Hip Pain in a young adult a case report
    Journal of Bone and Joint Surgery American Volume, 2010
    Co-Authors: Joshua Hamann, Kevin Marberry
    Abstract:

    In young, active patients, the common causes of Hip Pain are multiple and can include muscle strain, contusion, acetabular labral tear, osteochondral injury, sports hernia, snapping Hip, proximal femoral stress fracture, and spinal abnormalities1-3. In most patients, an initial trial of nonoperative management is instituted. If Pain persists or is of an unusual presentation, a more extensive diagnostic workup may be used. A thorough clinical evaluation can expedite the diagnosis of uncommon conditions of the musculoskeletal system, and the diagnostic evaluation may include magnetic resonance imaging of the pelvis and Hip to evaluate the integrity of the periarticular structures. The case of the patient in the present report illustrates an unusual presentation of disseminated Blastomyces dermatitidis infection causing Hip Pain that was diagnosed with magnetic resonance imaging and was successfully treated through a multidisciplinary approach. The parents of the patient were informed that data concerning the case would be submitted for publication, and they consented. A seventeen-year-old boy presented to our clinic with a chief complaint of an insidious onset of Hip Pain of approximately two weeks’ duration that was minimally responsive to nonsteroidal anti-inflammatory drugs. He had previously worked at a job in construction requiring heavy labor and lived in the Missouri River valley region. The Hip Pain was limiting his ability to work at his normal level. The Pain was primarily localized to the lateral aspect of the Hip at the greater trochanteric region and the lateral iliac wing without radiation. He denied any fevers, chills, or other constitutional symptoms …

  • the recognition and evaluation of patterns of compensatory injury in patients with mechanical Hip Pain
    Sports Health: A Multidisciplinary Approach, 2014
    Co-Authors: Sommer Hammoud, Asheesh Bedi, James E Voos, Craig S Mauro, Bryan T Kelly
    Abstract:

    Context:In active individuals with femoroacetabular impingement (FAI), the resultant reduction in functional range of motion leads to high impaction loads at terminal ranges. These increased forces result in compensatory effects on bony and soft tissue structures within the Hip joint and hemipelvis. An algorithm is useful in evaluating athletes with pre-arthritic, mechanical Hip Pain and associated compensatory disorders.Evidence Acquisition:A literature search was performed by a review of PubMed articles published from 1976 to 2013.Level of Evidence:Level 4.Results:Increased stresses across the bony hemipelvis result when athletes with FAI attempt to achieve supraphysiologic, terminal ranges of motion (ROM) through the Hip joint required for athletic competition. This can manifest as Pain within the pubic joint (osteitis pubis), sacroiliac joint, and lumbosacral spine. Subclinical posterior Hip instability may result when attempts to increase Hip flexion and internal rotation are not compensated for by i...

  • an algorithmic approach to mechanical Hip Pain
    HSS Journal, 2012
    Co-Authors: Lazaros A Poultsides, Asheesh Bedi, Bryan T Kelly
    Abstract:

    Background As our understanding of Hip pathology evolves, the focus is shifting toward earlier identification of Hip pathology. Therefore, it is vitally important to elucidate intra-articular versus extra-articular pathology of Hip Pain in every step of the patient encounter: history, physical examination, and imaging.

  • static and dynamic mechanical causes of Hip Pain
    Arthroscopy, 2011
    Co-Authors: Michael Leunig, Asheesh Bedi, Mark Dolan, Bryan T Kelly
    Abstract:

    Mechanical Hip Pain typically has been associated either with dynamic factors resulting in abnormal stress and contact between the femoral head and acetabular rim when the Hip is in motion or with static overload stresses related to insufficient congruency between the head and acetabular socket in the axially loaded (standing) position. Compensatory motion may adversely affect the dynamic muscle forces in the pelvic region, leading to further strain and Pain. Hip Pain related to static overload stresses may also be localized to the anteromedial groin, but compensatory dysfunction of the periarticular musculature may lead to muscular fatigue and associated Pain throughout the Hip. As our understanding of Hip joint mechanics has advanced, it has become increasingly apparent that Hip Pain in the absence of osteoarthritis may be due to a complex combination of mechanical stresses, both dynamic and static. With an emphasis on findings in the recent literature, this review will describe the dynamic and static factors associated with mechanical Hip Pain, the combinations of dynamic and static stresses that are commonly identified in Hip Pain, and common patterns of compensatory injury in patients with femoroacetabular impingement.

  • conservative management acutely improves functional movement and clinical outcomes in patients with pre arthritic Hip Pain
    Journal of Hip Preservation Surgery, 2020
    Co-Authors: Ryan P Mcgovern, Robroy L Martin, Amy L Phelps, Benjamin R Kivlan, Beth Nickel, John J Christoforetti
    Abstract:

    Conservative management for individuals with pre-arthritic Hip Pain is commonly prescribed prior to consideration of surgical management. The purpose of this study is to determine if patients with pre-arthritic Hip Pain will improve their functional movement control and clinical outcome measures following the implementation of physical therapy and a home-exercise programme. Information was retrospectively collected on consecutive patients and included: demographics, diagnosis, initial and follow-up evaluation of the single leg squat test (SLST) and step-down test (SDT), and patient-reported outcome measures. An independent t-test and one-way analysis of covariance were performed for continuous patient-reported outcome measures and a Fisher's exact test was performed for patient satisfaction. Forty-six patients (31 female and 15 male) diagnosed with pre-arthritic Hip Pain were included. A total of 30 patients improved their functional movement control during performance of the SLST, whereas 31 patients improved performance of the SDT. There was a statistically significant difference between patients that improved and did not improve (P ≤ 0.017). Patients with pre-arthritic Hip Pain who improved their functional movement control following a prescribed rehabilitation intervention are likely to report less Pain and greater functional ability in their daily and sports-related activities. This study supports conservative management to acutely improve outcomes for patients with pre-arthritic Hip Pain.

  • evidence based procedures for performing the single leg squat and step down tests in evaluation of non arthritic Hip Pain a literature review
    The International journal of sports physical therapy, 2018
    Co-Authors: Ryan P Mcgovern, Robroy L Martin, John J Christoforetti, Benjamin R Kivlan
    Abstract:

    Background Functional performance tests are commonly utilized in screening for injury prevention, evaluating for athletic injuries, and making return-to-play decisions. Two frequently performed functional performance tests are the single leg squat and step-down tests. Purpose The purpose of this study was to systematically review the available psychometric evidence for use of the single leg squat and step-down tests for evaluating non-arthritic Hip conditions and construct an evidence-based protocol for test administration. Study design Review of the Literature. Materials/methods A search of the PubMed and SPORTSDiscus databases was performed. Psychometric evidence of reliability, validity, and responsiveness to support the use of the both tests were collected. The protocols used for administering these tests were extracted, summarized, and combined. Results Of the 3,406 articles that were reviewed, 56 total articles met the inclusion criteria and were included in the review. Evidence for reliability and validity was available to support the use of the single leg squat and step-down tests. Both tests assess for neuromuscular control of the Hip and surrounding muscular structures. Evaluation of these functional movement patterns enable the clinician to assess for limitations that may cause an increase in Hip Pain and dysfunction. Conclusions The single leg squat and step-down tests can assess for kinematic and biomechanical deficiencies and may be useful in the evaluation process for individuals with non-arthritic Hip Pain. The authors of this review present a comprehensive evidence-based protocol for standardized performance of these tests. Level of evidence 2b.

  • accuracy of 3 clinical tests to diagnose proximal hamstrings tears with and without sciatic nerve involvement in patients with posterior Hip Pain
    Arthroscopy, 2018
    Co-Authors: Robroy L Martin, Ryan P Mcgovern, Juan Gomezhoyos, Ian James Palmer, Ricardo Goncalves Schroder, Anthony N Khoury, Hal D Martin
    Abstract:

    Purpose To determine the diagnostic accuracy of the active hamstring test at 30° (A-30) and 90° (A-90) of knee flexion, the long stride heel strike (LSHS) test, and combination of the 3 tests for individuals with hamstring tendon tears, with and without sciatic nerve involvement. Methods A retrospective review of 564 consecutive clinical records identified 42 subjects with a mean age of 50.31 ± 15 years who underwent a standard physical examination prior to magnetic resonance imaging (MRI) evaluation and diagnostic injection for posterior Hip. The physical examination included the A-30, A-90, and LSHS tests. Sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were calculated to determine the diagnostic accuracy of these 3 tests. Results Forty-two subjects (female = 32 and male = 10) with a mean age of 50.31 years (range 15-77, ± SD 14.52) met the inclusion criteria and were included in the review. Based on MRI and/or injection, 64.28% (27/42) of subjects were diagnosed with hamstring tear. Fourteen (51.85%) presented with sciatic nerve involvement. The sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio for each test were as follows: A-30 knee flexion: 0.73, 0.97, 23.43, 0.28, and 84.73; A-90 knee flexion: 0.62, 0.97, 20.00, 0.39, and 51.67; LSHS: 0.55, 0.73, 2.08, 0.61, and 3.44. The most accurate findings were obtained when the results of the A-30 and A-90 were combined, with sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio of 0.84, 0.97, 26.86, 0.17, and 161.89, respectively. Conclusion The combination of the active hamstring A-30 and A-90 tests proved to be a highly accurate and valuable tool to diagnose proximal hamstring tendons tears with or without sciatic nerve involvement in subjects presenting with posterior Hip Pain. Level of Evidence Level III, diagnostic study.

  • accuracy of 2 clinical tests for ischiofemoral impingement in patients with posterior Hip Pain and endoscopically confirmed diagnosis
    Arthroscopy, 2016
    Co-Authors: Robroy L Martin, Juan Gomezhoyos, Ricardo Schroder, Ian James Palmer, Hal D Martin
    Abstract:

    Purpose To establish the accuracy of the long-stride walking (LSW) and ischiofemoral impingement (IFI) tests for diagnosing IFI in patients whose primary symptom is posterior Hip Pain. Methods Confirmed IFI cases and cases in which IFI had been ruled out were identified considering imaging, injections, and endoscopic assessment, combined with Pain relief and negative IFI-specific tests after treatment. Demographic data, duration of symptoms, Pain location, ischiofemoral space, quadratus femoris space, quadratus femoris edema, surgical findings, and visual analog scale score for Pain before and after treatment were computed for all patients included in this study. Sensitivity, specificity, predictive values, likelihood ratios, and diagnostic odds ratios were computed individually for the LSW test and IFI test. Results Cases from 1,166 consecutive Hip operations and charts from 564 consecutive outpatients were retrospectively reviewed to identify patients who underwent injection and/or endoscopic surgery because of posterior Hip Pain. Thirty individuals (21 women and 9 men) with a mean age of 49.8 years (range, 20 to 76 years; standard deviation, 13.0 years) were included for analysis. Of the 30 patients, 17 (56.6%) were confirmed as positive for IFI and 13 (43.4%) were confirmed as negative for IFI. The IFI test had a sensitivity of 0.82, specificity of 0.85, positive predictive value of 0.88, negative predictive value of 0.79, positive likelihood ratio of 5.35, negative likelihood ratio of 0.21, and diagnostic odds ratio of 25.6. The LSW test had a sensitivity of 0.94, specificity of 0.85, positive predictive value of 0.89, negative predictive value of 0.92, positive likelihood ratio of 6.12, negative likelihood ratio of 0.07, and diagnostic odds ratio of 88.8. Conclusions In patients with complaints of posterior Hip Pain and negative evaluation findings for lumbosacral spine involvement or static/dynamic mechanical axis malalignment, the IFI and LSW tests are highly accurate to help identify those with or without IFI. Level of Evidence Level III, diagnostic study.

  • the diagnostic accuracy of a clinical examination in determining intra articular Hip Pain for potential Hip arthroscopy candidates
    Arthroscopy, 2008
    Co-Authors: Robroy L Martin, James J Irrgang, Jon K Sekiya
    Abstract:

    Purpose: One purpose of this study was to determine whether signs and symptoms could identify when a majority of the Hip Pain was originating from intra-articular sources in potential arthroscopic surgery candidates. The second purpose was to quantify Pain reduction after an anesthetic intra-articular injection in those with potential labral pathology. Methods: Subjects with Hip Pain being evaluated by an orthopaedic surgeon specializing in Hip arthroscopy were prospectively enrolled in the study. Clinical examination results were recorded. Sensitivity, specificity, and likelihood ratios were calculated to determine their accuracy in identifying those who would have greater than 50% Pain relief from those with 50% Pain relief or less. Results: We enrolled 105 subjects in this study. An anesthetic intra-articular injection was performed in 49 potential candidates for arthroscopic surgery (47%). The mean age in these 49 subjects was 42 years (SD, 15 years; range, 18 to 68 years), with 25 men (51%) and 24 women (49%). According to magnetic resonance imaging (MRI) arthrogram, 18 individuals had a definite labral tear, 29 had a possible tear, and 2 had no labral tears. In those with definite tears or possible tears, 39% (n = 7) and 45% (n = 13), respectively, did not achieve a greater than 50% reduction of Pain. Groin Pain, clicking, pinching Pain with sitting, lateral thigh Pain, flexion abduction external rotation test, flexion–internal rotation–adduction test, and trochanteric tenderness were not useful in identifying those with greater than 50% Pain relief from those with 50% relief or less. Conclusions: The symptoms and signs investigated in this study did not accurately or consistently identify subjects with primary intra-articular Pain sources. Furthermore, candidates for Hip arthroscopy with a labral tear identified on MRI arthrogram had varied responses to anesthetic intra-articular injection. Therefore all labral tears identified on MRI arthrogram may not be a major contributor to patients' Pain complaints, and medical personnel should look for other causes of Pain. Level of Evidence: Level III, diagnostic study of nonconsecutive patients (without consistently applied gold standard).

  • Magnetization-prepared 2 Rapid Gradient-Echo MRI for B1 Insensitive 3D T1 Mapping of Hip Cartilage: An Experimental and Clinical Validation.
    'Radiological Society of North America (RSNA)', 2021
    Co-Authors: Schmaranzer Florian, Afacan Onur, Lerch Till, Kim Young-jo, Siebenrock Klaus-arno, Ith Michael, Cullmann Jennifer, Kober Tobias, Klarhoefer Markus, Tannast Moritz
    Abstract:

    Background Often used for T1 mapping of Hip cartilage, three-dimensional (3D) dual-flip-angle (DFA) techniques are highly sensitive to flip angle variations related to B1 inhomogeneities. The authors hypothesized that 3D magnetization-prepared 2 rapid gradient-echo (MP2RAGE) MRI would help provide more accurate T1 mapping of Hip cartilage at 3.0 T than would 3D DFA techniques. Purpose To compare 3D MP2RAGE MRI with 3D DFA techniques using two-dimensional (2D) inversion recovery T1 mapping as a standard of reference for Hip cartilage T1 mapping in phantoms, healthy volunteers, and participants with Hip Pain. Materials and Methods T1 mapping at 3.0 T was performed in phantoms and in healthy volunteers using 3D MP2RAGE MRI and 3D DFA techniques with B1 field mapping for flip angle correction. Participants with Hip Pain prospectively (July 2019-January 2020) underwent indirect MR arthrography (with intravenous administration of 0.2 mmol/kg of gadoterate meglumine), including 3D MP2RAGE MRI. A 2D inversion recovery-based sequence served as a T1 reference in phantoms and in participants with Hip Pain. In healthy volunteers, cartilage T1 was compared between 3D MP2RAGE MRI and 3D DFA techniques. Paired t tests and Bland-Altman analysis were performed. Results Eleven phantoms, 10 healthy volunteers (median age, 27 years; range, 26-30 years; five men), and 20 participants with Hip Pain (mean age, 34 years ± 10 [standard deviation]; 17 women) were evaluated. In phantoms, T1 bias from 2D inversion recovery was lower for 3D MP2RAGE MRI than for 3D DFA techniques (mean, 3 msec ± 11 vs 253 msec ± 85; P < .001), and, unlike 3D DFA techniques, the deviation found with MP2RAGE MRI did not correlate with increasing B1 deviation. In healthy volunteers, regional cartilage T1 difference (109 msec ± 163; P = .008) was observed only for the 3D DFA technique. In participants with Hip Pain, the mean T1 bias of 3D MP2RAGE MRI from 2D inversion recovery was -23 msec ± 31 (P < .001). Conclusion Compared with three-dimensional (3D) dual-flip-angle techniques, 3D magnetization-prepared 2 rapid gradient-echo MRI enabled more accurate T1 mapping of Hip cartilage, was less affected by B1 inhomogeneities, and showed high accuracy against a T1 reference in participants with Hip Pain. © RSNA, 2021
