Arch Phys Med Rehabil 2024; 105:655-663. [PMID: 38163530 DOI: 10.1016/j.apmr.2023.12.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 12/04/2023] [Accepted: 12/05/2023] [Indexed: 01/03/2024]
Abstract
OBJECTIVE This study compares the clinical and ultrasonographic efficacy of 2 splint types, the lateral epicondylitis band (LEB) and the wrist extensor splint (WES), for treatment of lateral epicondylitis (LE). DESIGN Randomized controlled single-blind trial. SETTING Outpatient clinic. PARTICIPANTS 159 participants diagnosed with unilateral LE based on clinical and ultrasonographic findings, and 2-12 weeks from symptom onset, were included (N=159). INTERVENTIONS One group received joint-protection education-only (wait-and-see), while the other 2 groups were fit with splints: one the LEB and the other the WES. Both splint groups received joint-protection education. MAIN OUTCOME MEASURES The primary outcome measure was the Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire. Secondary outcome measures were the Visual Analog Scale (VAS) for pain, hand grip strength by dynamometry, algometric measurements, patient satisfaction, and selected ultrasonographic parameters (maximum tendon thickness measurements (MTTM) in the capitellar-radiocapitellar region and total ultrasonography scale score [TUSS]). All outcomes were assessed at baseline, 3-weeks, and 6-weeks post intervention initiation. RESULTS Participants' mean age was 46.85±8.63 years. Of the participants, 40.88% (n=65) were male and 59.12% (n=94) were female. The baseline median (1Q-3Q) values of PRTEE-total scores were 58.5 (51-68) for the LEB, 63.5 (56.25-70.25) for the WES and 57 (48-68) for the education-only groups. At 6-weeks, the PRTEE-total scores had decreased by 44 points for those randomized to the LEB, 46 points to the WES and 7 points in the education-only groups(P<.001). While the LEB and WES approaches were superior to the wait-and-see approach in algometric measurements, VAS, and PRTEE scores (P<.05), no significant changes were found in MTTM and TUSS values. The LEB group was superior to the WES group in hand grip strength and patient satisfaction (P<.05). CONCLUSION Using either splint for 6 weeks can be considered effective for the relief of pain and increased functionality in persons with subacute LE, although the LEB had a more positive effect on grip strength and patient satisfaction than the WES.

Effectiveness of High-Power Laser Therapy via Shear Wave Speed Analysis on Pain and Functioning in Patients with Lateral Epicondylitis: A Proof-of-Concept Study. J Clin Med 2024; 13:2014. [PMID: 38610779 PMCID: PMC11012724 DOI: 10.3390/jcm13072014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 03/22/2024] [Accepted: 03/26/2024] [Indexed: 04/14/2024] Open
Abstract
Background: Lateral epicondylitis (LE) causes lateral elbow pain due to the overuse of the common extensor tendon. Several therapies have been proposed for pain relief and functional recovery, including physical therapy, minimally invasive injection approaches, and physical agent modalities such as laser therapy. Methods: Our study evaluates the impact of high-power laser therapy (HPLT) on pain and functioning. The HPLT protocol consists of 10 daily sessions using a LASERIX PRO device. The healthy elbow of each participant was also considered as a control group. The outcomes assessed were the Numerical Rating Scale (NRS) for pain, QuickDASH questionnaire for functionality, and shear wave velocity (SWS) through ultrasonography. Assessments were conducted at baseline (T0), post-treatment (T1), and 2-week follow-up (T2). Results: Sixteen participants (81.2% male, mean age 40.4 ± 5.53 years) completed the study. Post-treatment, pain significantly decreased (NRS: T0 6.13 ± 0.96; T1 2.75 ± 1.69; p < 0.001), functionality improved (QuickDASH: T0 69.88 ± 10.75; T1 41.20 ± 3.78; p < 0.001), and shear wave velocity increased (SWS (m/s): T0 1.69 ± 0.35; T1 2.56 ± 0.36; p < 0.001). Conclusions: At the 2-week follow-up, pain relief was maintained, and shear wave velocity showed no further significant change. Shear wave velocity assessments might be considered a useful diagnostic tool. However, further research is needed to support the role of HPLT and shear wave velocity in the rehabilitation management of LE.

Abstract
To evaluate the relationship of ultrasonographic evaluation parameters with pain, muscle strength and disease severity in lateral epicondylitis (LE). 64 people were included in present retrospective, cross-sectional study. Activity and rest pain was questioned with Visual Analog Scale (VAS). Also, Patient Rated Tennis Elbow Evaluation (PRTEE) and the maximum grip strength were evaluated. Hypoechoic region, neovascularity, cortical irregularity, enthesopathy and peritendinous fluid or bursitis were evaluated by ultrasonography. 48 of the patients were female and 16 were male. Mean age was 48.53 ± 6.12, body mass index was 27.70 ± 4.75. 55 (85.9%) hypoechoic region, 31 (48.4%) neovascularity, 21 (32.8%) cortical irregularity, 19 (29,7%) enthesopathy, and 18 (28.1%) peritendinous fluid or bursitis were detected by ultrasonography. When the ultrasonographic findings and clinical findings of the patients were compared, no significant difference was found between the hypoechoic region, cortical irregularity, enthesopathy and clinical findings (P > .05), while the extension grip strength was found to be significantly lower in patients with neovascularity (P = .045). In addition, patients with peritendinous fluid or bursitis, were found to be significantly lower in both flexion (P = .033) and extension (P = .023) grip strength, while PRTEE function (P = .021) subgroup and total (P = .038) scores were significantly higher. Hypoechoic region, cortical irregularities and enthesopathy were not evaluated to be associated with disease severity, pain and muscle strength. Neovascularity was found to be associated only with extension grip strength. Peritendinous fluid or bursitis was found to be associated with both flexion and extension grip strength and disease activity, but not associated with pain.

Abstract
Background: Lateral epicondylitis (LE) is one of the most diagnosed elbow pathologies. The purpose of this study was to determine the diagnostic test accuracy of a new test (selfie test) for the diagnosis of LE. Methods: Medical data were collected from adult patients who presented with LE symptoms and ultrasound findings that supported the diagnosis. Patients underwent a physical examination, including provocative tests for diagnosis as well as the selfie test, and were asked to fill out the Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire and subjectively rate the activity of their affected elbow. Results: Thirty patients were included in this study (seventeen females, 57%). The mean age was 50.1 years old (range of 35 to 68 years). The average duration of symptoms was 7 ± 3.1 months (range of 2 to 14 months). The mean PRTEE score was 61.5 ± 16.1 (range of 35 to 98), and the mean subjective elbow score was 63 ± 14.2 (range of 30 to 80). Mill's, Maudsley's, Cozen's, and the selfie tests had sensitivities of 0.867, 0.833, 0.967, and 0.933, respectively, with corresponding positive predictive values of 0.867, 0.833, 0.967, and 0.933. Conclusions: The selfie test's active nature, which allows patients to perform the assessment themselves, could be a valuable addition to the diagnostic process, potentially improving the accuracy of the diagnosis of LE (levels of evidence: IV).

Abstract
Diagnostic imaging of epicondylitis is primarily performed using widely available, radiation-free ultrasound. The dynamic examination allows a rapid point-of-care assessment. Typical imaging findings of epicondylitis include intratendinous hypoechogenic foci at the humeral origin, ossification at the enthesis, intratendinous calcifications, or (partial) rupture. In particular, Doppler sonography increases sensitivity by assessing possible neovascularization within the tendon. When sonographic findings are unclear or extensive, or when ultrasound machines or the required expertise in elbow examinations are not available, magnetic resonance imaging is indicated. Here, the use of proton density-weighted sequences is appropriate for assessing bone marrow and soft tissue edema and tendon tears, while ossifications are best delineated in T1weighted sequences. Projection radiography and computed tomography can be helpful for larger ossifications, although they are not part of the standard imaging protocol.

Abstract
ABSTRACT Injury to the flexor pronator mass is a common condition that is especially prevalent in overhead throwing athletes. The increasing incidence of these injuries has promoted considerable efforts in research to better understand the pathology, risk factors, and potential mechanisms to prevent injury in these athletes. While there are numerous intrinsic and extrinsic factors associated with injury, a common theme involves chronic overuse and microtrauma with inadequate resting intervals between performances. The purpose of this review is to discuss medial elbow injuries in young athletes with a particular focus on the flexor pronator mass.

Abstract
Objective: Determine the prevalence of lateral epicondylosis (LE) of the dominant elbow in manual wheelchair users based on ultrasound assessment and physical exam.Design: Prospective, cross-sectional.Setting: National Veteran Wheelchair Games 2018 and 2019 (event medical services).Participants: Manual wheelchair users who attended the National Veteran Wheelchair Games (n = 87).Interventions: Participants completed a questionnaire then underwent an ultrasound assessment and a physical exam of their dominant arm evaluating for common extensor tendinopathy (CET) or clinically LE.Main Outcome Measure: Prevalence of CET diagnosed by ultrasound criteria was compared with other diagnostic criteria with MaNemar test for paired binary data.Results: Forty-six percent (N = 40) of participants met diagnostic criteria for CET by ultrasound assessment and 17% (N = 15) of participants met criteria for LE based on physical exam. These values are dramatically higher than what has been reported in the able-bodied population where the prevalence is estimated to be <2%. Age and number of years of wheelchair use were significant predictors of ultrasound diagnosis of LE (P = 0.02, 95% confidence interval [CI] 1.01-1.11) and (P = 0.05, 95% CI 1.00-1.09), respectively. Association analysis based on odds ratio and CI found no association between ultrasound findings suggestive of LE with regular adaptive sport participation greater than 1.5 h per week.Conclusion: Compared to able-bodied population, there is an increased prevalence of both CET and LE in manual wheelchair users based on either ultrasound assessment or physical exam. CET is associated with increased age and increased years using a manual wheelchair. There is no association between the diagnosis of LE and participation in adaptive sport.

Abstract
Medial and lateral elbow pain are often due to degenerative tendinosis and less commonly due to trauma. The involved structures include the flexor-pronator tendon origin in medial-sided pain and the extensor tendon origin in lateral-sided pain. Multimodality imaging is often obtained to verify the clinically suspected diagnosis, evaluate the extent of injury, and guide treatment decisions. Image-guided procedures can provide symptom relief to support physical therapy and also induce tendon healing. Surgical debridement and repair are typically performed in refractory cases, resulting in good to excellent outcomes in most cases. In this article, we review and illustrate pertinent anatomical structures of the distal humerus, emphasizing the structure and contributions of the flexor-pronator and extensor tendon origins in acute and chronic tendon abnormalities. We also discuss approaches to image-guided treatment and surgical management of medial and lateral epicondylitis.

Abstract
OBJECTIVE The aim was to analyze effects of a percutaneous neuromodulation (PNM) treatment on the radial nerve, regarding pain, functionality, electrophysiologic excitability, and morphology, in patients with chronic lateral epicondylalgia (LE). METHODS Twenty-four patients with chronic unilateral elbow pain were recruited for this preliminary study and were divided into two groups: control (n = 12) and PNM group (n = 12). The subjects in the PNM group received percutaneous peripheral neurostimulation with an acupuncture needle that was located next to the nerve with ultrasound guidance. Pain using a numerical rating scale (NRS), functional ability using patient-rated tennis elbow evaluation (PRTEE), radial nerve cross-sectional area measured by ultrasound, and chronaxie and accommodation index (AI) measured by the strength-duration curve were evaluated. RESULTS Both groups showed no differences in the baseline measurements (all p = 0.001). However, at the end of the treatment, there were significant differences between groups since only the PNM group significantly improved their values compared to their baseline values: level of pain and cross-sectional area (CSA) values showed a significant decrease while the PRTEE scores showed a significant improvement. Then, regarding AI, the PNM group showed significant improvement for the electrophysiologic nerve excitability pattern, reporting normal function in all radial nerves after treatment (p = 0.001). However, chronaxie values always reported similar values with no differences between groups (p >0.05); Conclusion: Ultrasound-PNM technique may be an interesting therapeutic tool for the treatment of chronic LE due to the improvement in the level of pain, functionality, nerve morphology, and excitability in this population.

Abstract
BACKGROUND Reviews on the diagnostic performance of the examination tests for lateral elbow tendinopathy (LET) based on updated context-specific tools and guidelines are missing. PURPOSE To review the diagnostic accuracy of examination tests used in LET. DESIGN Systematic review following PRISMA-DTA guidelines. METHODS We searched MEDLINE, PubMed, CINAHL, EMBASE, PEDro, ScienceDirect, and Cochrane Library databases. The QUADAS-2 checklist was used to assess the methodological quality of the eligible studies. We included diagnostic studies reporting the accuracy of physical examination tests or imaging modalities used in patients with LET. RESULTS Twenty-four studies with 1370 participants were identified reporting the diagnostic performance of Ultrasound Imaging (USI) (18 studies), physical examination tests (2 studies) and Magnetic Resonance Imaging (MRI) (4 studies). Most studies (97%) were assessed with "unclear" or "high risk" of bias. Sonoelastography showed the highest sensitivity (75- 100%) and specificity (85- 96%). Grayscale with or without Doppler USI presented poor to excellent values (sensitivity: 53%-100%, specificity: 42%-90%). MRI performed better in the diagnosis of tendon thickening and enthesopathy (sensitivity and specificity: 81%-100%). The Cozen's test reported high sensitivity (91%) while a grip strength difference of 5%-10% between elbow flexion and extension showed high sensitivity (78%-83%) and specificity (80%-90%). CONCLUSIONS Cozen's test and grip strength measurement present high accuracy in the diagnosis of LET but are poorly investigated. USI and MRI provide variable diagnostic accuracy depending on the entities reported and should be recommended with caution when differential diagnosis is necessary. Substantial heterogeneity was found in inclusion criteria, operator/ examiner, mode of application, type of equipment and reference standards across the studies.

Abstract
Background/aim The aim of this study was to compare the clinical and sonographic effects of the ultrasound (US) therapy, extracorporeal shock wave therapy (ESWT), and Kinesio taping (KT) in the lateral epicondylitis (LE). Materials and methods A total of 40 patients with LE were included in the present study. The patients were randomly assigned to 3 treatment groups: US (n = 13), ESWT (n = 14), and KT (n = 13) groups. Results The visual analog scale (VAS) scores significantly decreased in all groups (P < 0.05). Grip strength significantly increased after 8 weeks in only the KT group (P < 0.05). The Patient-Rated Tennis Elbow Evaluation Scale (PRTEE) scores significantly decreased after 2 weeks and after 8 weeks in the US group and ESWT groups, and after 8 weeks in the KT group (P < 0.05). Common extensor tendon (CET) thicknesses significantly decreased after 8 weeks in only the ESWT group (P < 0.05). Conclusion The US therapy, KT, and ESWT are effective in reducing pain and improving functionality. However, none of these treatment methods were found to be superior to others in reducing the pain and improving functionality.

[PMID: 33634322 DOI: 10.1007/s00330-021-07791-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Revised: 01/26/2021] [Accepted: 02/15/2021] [Indexed: 10/22/2022]
Abstract
OBJECTIVES To evaluate the ability of shear wave elastography (SWE) in diagnosing medial epicondylitis and to compare the diagnostic performance of SWE with that of grey-scale ultrasound (GSU) and strain elastography (SE). METHODS GSU, SE, and SWE were performed on 61 elbows of 54 patients from March 2018 to April 2019. An experienced radiologist evaluated the GSU findings (swelling, cortical irregularity, hypoechogenicity, calcification, and tear), colour Doppler findings (hyperaemia), SE findings (strain ratio [SR]), and SWE findings (stiffness and shear wave velocity [SWV]). Participants were divided in two groups: patients with clinically diagnosed medial epicondylitis and patients without medial elbow pain. Findings from the two groups were compared, and the receiver operating characteristic (ROC) curves were calculated for significant features. RESULTS Of the 54 patients, 25 patients with 28 imaged elbows were clinically diagnosed with medial epicondylitis and 29 patients with 33 imaged elbows had no medial elbow pain. Cortical irregularity, hypoechogenicity, calcification, hyperaemia, SR, stiffness, and SWV were significantly different between the two groups. The areas under the ROC curves were 0.838 for hypoechogenicity, 0.948 for SR, 0.999 for stiffness, and 0.999 for SWV. The diagnostic performances of SR, stiffness, and SWV were significantly superior compared to that of hypoechogenicity. However, there were no significant differences among SR, stiffness, and SWV. CONCLUSIONS SWE can obtain both stiffness and SWV, which are valuable diagnostic tools in the diagnosis of medial epicondylitis. The diagnostic performance of SWE and SE is similar in detecting medial epicondylitis. KEY POINTS • Shear wave elastography providing stiffness and shear wave velocity showed excellent performance in the diagnosis of medial epicondylitis. • There was no significant difference in the ability of SE and SWE for diagnosing medial epicondylitis.

Abstract
BACKGROUND There is no knowledge about the effects of kinesio taping (KT) on the radial nerve in lateral epicondylitis. OBJECTIVE This study aimed to determine the effects of non-steroidal-anti-inflammatory drugs (NSAIDs) combined with KT on lateral epicondylitis using ultrasonographic findings. METHODS NSAID therapy was administered to the control group for 10 days, and the KT group additionally received KT three times a week for two weeks. Clinical and ultrasonographic evaluations were performed before treatment and at post-treatment at second, sixth and fourteenth weeks. The radial nerve cross sectional area and common extensor tendon thicknesses were measured using ultrasonography. RESULTS The study was completed with 40 patients in each group. Improvements in clinical parameters, common extensor tendon thickness, and cross sectional area values were significant in the KT group (p<0.01). CONCLUSIONS NSAID plus kinesio taping decrease pain intensity while improving functionality and ultrasonographic parameters, including common extensor tendon thickness and radial nerve cross sectional area; therefore, it may be an option treatment in lateral epicondylitis.

Abstract
Background Lateral epicondylitis (LE) most commonly affects the Extensor Carpi Radialis Brevis (ECRB) tendon and patients are generally treated with injection therapy. For optimal positioning of the injection, as well as an estimation of the surface area and content of the ECRB tendon to determine the volume of the injectable needed, it is important to know the exact location of the ECRB in relation to the skin as well as the variation in tendon length and location. The aim of this study was to determine the variation in location and size of the ECRB tendon in patients with LE. Methods An observational sonographic evaluation of the ECRB tendon was performed in 40 patients with LE. The length of the ECRB tendon, distance from the cutis to the center of the ECRB tendon, the length of the osteotendinous junction at the epicondyle and the distance from cutis to middle of the osteotendinous junction were measured. Results The average tendon length was 1.68cm (range 1.27-1.98; SD 0.177). Compared to women, the ECRB tendon of men was on average 0.12cm longer. Overall, the average distance from cutis to the center of the ECRB was 0.75cm (range 0.50-1.46cm; SD 0.210), the average length of the junction was 0.55cm (range 0.35-0.87; SD 0.130), and the distance from cutis to middle of the osteotendinous junction was 0.73cm (range 0.40-1.25cm; SD 0.210). Conclusion The size and depth of the ECRB tendon in patients with LE is largely variable. While there are no studies yet suggesting sono-guided injection to be superior to that of blind injection, the anatomic variability of this study suggests that the accuracy of injection therapy for LE might be compromised when based solely on bony landmarks and therefore not fully reliable. As a result, there is value in further studies exploring the accuracy of the ultrasound guided injection techniques.

Abstract
Common flexor-pronator tendon injuries and medial epicondylitis can be successfully treated nonoperatively in most cases. Operative treatment is reserved for patients with continued symptoms despite adequate nonoperative treatment or in high-level athletes with complete rupture of the common flexor-pronator tendon. The physical examination and workup of patients with flexor-pronator tendon injuries should focus on related or concomitant pathologies of the medial elbow. The gold standard for surgical treatment of flexor-pronator tendon ruptures or medial epicondylitis includes tendon debridement and reattachment.

Abstract
Background To investigate the role of shear wave elastography (SWE) in patients with lateral epicondylitis (LE) by assessing the common extensor tendon (CET) elasticity. Methods A total of 62 unilateral LE patients were enrolled. Shear wave speed (SWS) and the thickness of CET in both elbows, along with the involved elbows with pre- and post-treatment, were obtained by SWE. The differences between groups, inter- and intra-observer agreements, and diagnostic accuracy were analyzed with a paired t-test, intraclass correlation coefficients (ICCs), and receiver operator characteristic (ROC) curve, respectively. Results LE patients had significantly lower SWS on lesion sides compared to healthy elbows (P<0.05). The SWS of involved elbows were significantly higher after non-operation treatment than before treatment. The inter- and intra-observer agreements were excellent (ICCs: 0.900-0.993) for SWE measurements. Moreover, a 12.2 m/s cutoff value of mean SWS (C mean) for discriminating LE patients from healthy subjects revealed a sensitivity and specificity of 93% and 93%, respectively. Conclusions SWE is a valid imaging technique for the diagnosis of LE and monitoring of the treatment effect. Future studies are essential for investigating the correlations among clinical examinations, conventional ultrasound, and SWE.

Abstract
OBJECTIVES To compare the accuracy of homodyned K quantitative ultrasound (QUS) with that of B-mode and Doppler ultrasound imaging for discriminating between lateral epicondylosis (LE) and asymptomatic elbows. METHODS This prospective study received Institutional Review Board approval, and participants provided written informed consent. Between February 2015 and March 2017, 30 LE elbows in 27 patients and 24 asymptomatic elbows in 13 volunteers underwent B-mode, Doppler, and radiofrequency ultrasound imaging of the common extensor tendon (CET) and radial collateral ligament (RCL). Two readers classified the elbows independently on the basis of a review of B-mode and Doppler images. The global and local estimates of QUS parameters (μ n , 1/α, and k) were computed in the CET and CET-RCL regions, respectively, and the area of each region was calculated. A random-forest classifier identified the most discriminating 3-parameter combination: CET global estimate of 1/α, CET-RCL area, and local estimate of k. RESULTS The patients with LE had a mean age of 50 years (range, 31-66 years), and the volunteers had a mean age of 50 years (range, 37-57 years). The area under the receiver operating characteristic curve, sensitivity, and specificity of reader 1, reader 2, and the QUS-based model were 0.80 (95% confidence interval [CI], 0.66-0.95), 0.72 (95% CI, 0.56-0.89), and 0.88 (95% CI, 0.72-1.04); 0.79 (95% CI, 0.66-0.93), 0.65 (95% CI, 0.47-0.82), and 0.84 (95% CI, 0.67-1.01); and 0.82 (95% CI, 0.80-0.85), 0.73, and 0.79, respectively. CONCLUSIONS An automated, computer-based QUS technique diagnosed LE with accuracy of 0.82. This technique could provide quantitative biomarkers for the characterization of LE disease.

Abstract
BACKGROUND Persistent strength deficits secondary to Achilles tendinopathy (AT) have been postulated to account for difficulty engaging in tendon-loading movements, such as running and jumping, and may contribute to the increased risk of recurrence. To date, little consensus exists on the presence of strength deficits in AT. Consequently, researchers are uncertain about the appropriate methods of assessment that may inform rehabilitation in clinical practice. OBJECTIVE To evaluate and synthesize the literature investigating plantar-flexion (PF) strength in individuals with AT. STUDY SELECTION Two independent reviewers searched 9 electronic databases using an agreed-upon set of key words. DATA EXTRACTION Data were extracted from studies comparing strength measures (maximal, reactive, and explosive strength) between individuals with AT and healthy control participants or between the injured and uninjured sides of people with AT. The Critical Appraisal Skills Programme Case-Control Study Checklist was used to assess the risk of bias for the included studies. DATA SYNTHESIS A total of 19 studies were eligible. Pooled meta-analyses for isokinetic dynamometry demonstrated reductions in maximal strength (concentric PF peak torque [PT] slow [Hedges g = 0.52, 44% deficit], concentric PF PT fast [Hedges g = 0.61, 38% deficit], and eccentric PF PT slow [Hedges g = 0.26, 18% deficit]). Reactive strength, particularly during hopping, was also reduced (Hedges g range = 0.32-2.61, 16%-35% deficit). For explosive strength, reductions in the rate of force development (Hedges g range = 0.31-1.73, 10%-21% deficit) were observed, whereas the findings for ground reaction force varied but were not consistently altered. CONCLUSIONS Individuals with AT demonstrated strength deficits compared with the uninjured side or with asymptomatic control participants. Deficits were reported across the strength spectrum for maximal, reactive, and explosive strength. Clinicians and researchers may need to adapt their assessment of Achilles tendon function, which may ultimately help to optimize rehabilitation outcomes.

Abstract
OBJECTIVE Enthesitis is a manifestation of psoriatic arthritis (PsA), but its symptoms are difficult to interpret clinically. We investigated the associations of ultrasonographic changes in entheses with clinical characteristics in patients with PsA, and compared enthesis changes of patients aged 35 to 60 years with healthy volunteers of that age. METHODS Consecutive patients with PsA participated in this cross-sectional study, irrespective of enthesitis complaints and age. We collected data about complaints, physical activity and activity avoidance, medication, and clinical enthesitis. Inflammatory and structural enthesis changes were scored with the modified MAdrid Sonographic Enthesitis Index (MASEI). Among all patients, associations between ultrasound (US) scores and clinical characteristics were investigated using linear regression. We compared US scores of healthy volunteers and patients with PsA aged 35-60 years using Wilcoxon rank-sum tests. RESULTS Eighty-four patients with PsA and 25 healthy volunteers participated. In patients with PsA, we found a small association between higher inflammatory-modified MASEI score and older age (β 0.07, 95% CI 0-0.13) and current use of biologics (β 1.56, 95% CI 0.16-2.95). Patients who reported avoiding activities had significantly lower inflammatory-modified MASEI scores (β -1.71, 95% CI -3.1 to -0.32) than those who did not. The patients with PsA aged 35-60 years (n = 50) had similar inflammatory scores as healthy volunteers but higher structural scores (median 6 vs 2; p = 0.01). CONCLUSION Within patients with PsA, avoiding physical activity, younger age, and not using biologics were associated with less enthesis inflammation. Patients with PsA and healthy volunteers aged 35 to 60 years displayed similar levels of inflammatory changes of the entheses, but patients had more structural damage.

Interobserver variability and stiffness measurements of normal common extensor tendon in healthy volunteers using shear wave elastography. Skeletal Radiol 2019; 48:137-141. [PMID: 30006828 DOI: 10.1007/s00256-018-3021-6] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2018] [Revised: 06/04/2018] [Accepted: 06/24/2018] [Indexed: 02/02/2023]
Abstract
OBJECTIVES The purposes of our study are to determine the quantitative elasticity values of normal common extensor tendon (CET) and to assess the interobserver variability of stiffness measurements using shear wave elastography (SWE). MATERIALS AND METHODS A total of 60 CETs of 30 (15 female, 15 male, mean age 30.2 years) healthy volunteers without any symptoms of lateral epicondylitis were examined by two radiologists. Age, sex, height, weight, body mass index (BMI), and dominant hand of all participants were noted. The first observer performed B-mode and SWE imaging, and the second observer performed only SWE imaging. Tendon thickness and stiffness values in kPa were measured. RESULTS The mean thickness of CETs was 3.57 ± 0.36 mm. The mean stiffness values of CETs for two observers were 45.28 ± 9.82 kPa and 45.80 ± 9.72 kPa respectively. Tendon thickness had a weak correlation with weight (r = 0.281, p = 0.03), and moderate correlation with stiffness values (r = 0.429, p < 0.001). The mean interobserver difference of CET stiffness measurements was -0.5% of the mean CET stiffness values. Range of measurement error, defined as 95% limits of agreement, was ±23.5%. There was no significant difference between absolute values of interobserver measurements (p = 0.741). CONCLUSION Shear wave elastography is a reproducible imaging technique for the evaluation of CET elasticity and the standard stiffness values of normal CET can be used as reference data to differentiate normal from pathological tissues.

Abstract
The objective of this study was to evaluate the diagnostic accuracy of sonoelastography in patients of primary and secondary health care settings. Google scholar, PubMed, Medline, Medscape, Wikipedia and NCBI were searched in October 2017 for all original studies and review articles to identify the relevant material. Two reviewers independently selected articles for evaluation of the diagnostic accuracy of sonoelastography in different diseases based on titles and abstracts retrieved by the literature search. The accuracy of sonoelastography in different diseases was used as the index text, while B-mode sonography, micro pure imaging, surgery and histological findings were used as reference texts. Superficial lymph nodes, neck nodules, malignancy in thyroid nodules, benign and malignant cervical lymph nodes, thyroid nodules, prostate carcinoma, benign and malignant breast abnormalities, liver diseases, parotid and salivary gland masses, pancreatic masses, musculoskeletal diseases and renal disorders were target conditions. The data extracted by the two reviewers concerning selected study characteristics and results were presented in tables and figures. In total, 46 studies were found for breast masses, lymph nodes, prostate carcinoma, liver diseases, salivary and parotid gland diseases, pancreatic masses, musculoskeletal diseases and renal diseases, and the overall sensitivity of sonoelastography in diagnosing all these diseases was 83.14% while specificity was 81.41%. This literature review demonstrates that sonoelastography is characterized by high sensitivity and specificity in diagnosing different disorders of the body.

Abstract
Summary. The correct management of acute, subacute and overuse-related elbow pathologies represents a challenging diagnostic and therapeutic problem. While major trauma frequently requires a rapid surgical intervention, subluxation and minor trauma allow taking more time for diagnostics and planning the correct elective treatment after careful clinical and radiological investigation. In these conditions, communication between orthopaedic surgeon and radiologist allow to create a detailed radiology report, tailored to the patient’s and surgeon’s needs and optimal to plan proper management. Imaging technique as X-Ray, CT, US, MRI, CTA and MRA all belong to the radiologist’s portfolio in elbow diagnostics. Detailed knowledge of elbow pathology and its classification and of the possibilities and limits of each imaging technique is of crucial importance to reach the correct diagnosis efficiently. The aim of this review is to present the most frequent elbow pathologies and suggest a suitable diagnostic approach for each of them. (www.actabiomedica.it)

Abstract
OBJECTIVES We aimed to describe sonographic structural and inflammatory changes in entheses of patients with recently diagnosed psoriatic arthritis (PsA), patients with established PsA, and young healthy volunteers, and to investigate whether the MAdrid Sonographic Enthesitis Index (MASEI) enables us to distinguish these groups in an extreme comparison. METHOD New and established PsA patients and healthy volunteers (aged 20-30 years) were recruited. The triceps, quadriceps, patellar, Achilles and elbow extensor tendon insertion, and plantar fascia entheses were investigated sonographically for structural changes, erosions, calcifications, increased thickness, bursitis, and power Doppler (PD) signal according to the MASEI. RESULTS The study included 25 new and 25 established PsA patients, and 25 healthy volunteers. Increased thickness and PD signal in knee entheses were common for patients and healthy volunteers, while changes at other locations predominantly occurred in patients only. PD was recoded (1, one spot; 1.5, two or three spots; 2, confluent signal; 3, severe confluent signal) and thickness of knee entheses excluded. This resulted in different modified MASEI scores between PsA patients and young healthy controls: median (interquartile range) modified MASEI of 13 (10-22.5) in new PsA, 13.5 (9.5-18) in established PsA, and 3 (1-8.5) in healthy volunteers (p = 0.002). CONCLUSIONS Structural ultrasound changes and PD in entheses are common in both new and established PsA and healthy controls. MASEI score did not differentiate PsA patients from young healthy volunteers. After recoding of PD severity and excluding thickness of knee entheses, marked differences between PsA patients and healthy controls were observed.

Abstract
OBJECTIVES We assessed the implications of MR imaging with clinical history in lateral epicondylitis management by evaluating imaging and clinical features in patients with lateral epicondylitis treated conservatively or operatively. METHODS Sixty patients with lateral epicondylitis treated conservatively (n = 38) or operatively (n = 22) from 2011-2015 were included. MR imaging findings of common extensor tendon (CET), lateral collateral ligament (LCL) complex, muscle oedema, ulnar nerve and elbow joint were reviewed. Clinical data recorded were frequency, duration and intensity of pain, history of trauma and injection therapy, range of motion. RESULTS MRI-assessed CET and LCL complex abnormalities, muscle oedema, radiocapitellar joint widening, joint effusion/synovitis, pain frequency and intensity differed significantly between the two groups (p < .05) with increased severity in operative group. Persistent pain (OR 12.2, p < .01), CET abnormality on longitudinal plane (OR 7.5, p = .03 for grade 2; OR 22.4, p < .01 for grade 3) and muscle oedema (OR 6.7, p = .03) were major factors associated with operative treatment. Area under the ROC curve of predicted probabilities for combination of these factors was 0.83. CONCLUSION MR imaging, combined with clinical assessment, could facilitate appropriate management planning for patients with lateral epicondylitis. KEY POINTS • MRI can reflect different disease severity between patients treated conservatively/operatively. • CET abnormality, muscle oedema were major MRI findings with operative treatment. • Patients in operative group were more likely to experience persistent pain. • MRI plus clinical symptoms could facilitate appropriate management for lateral epicondylitis.

Abstract
Few studies discuss kinetic changes in tendinopathy models. We propose a customized corridor to evaluate dynamic weight bearing (DWB) and shearing forces. Sixty rats were randomly given ultrasound-assisted collagenase injections (Collagenase rats) or needle punctures (Control rats) in their left Achilles tendons, and then evaluated 1, 4, and 8 weeks later. The Collagenase rats always had significantly (p < 0.001) higher histopathological and ultrasound feature scores than did the Controls, significantly lower DWB values in the injured than in the right hindlimbs, and compensatorily higher (p < 0.05) DWB values in the contralateral than in the left forelimbs. The injured hindlimbs had lower outward shearing force 1 and 4 weeks later, and higher (p < 0.05) push-off shearing force 8 weeks later, than did the contralateral hindlimbs. Injured Control rat hindlimbs had lower DWB values than did the contralateral only at week 1. The Collagenase rats had only lower static weight bearing ratios (SWBRs) values than did the Controls at week 1 (p < 0.05). Our customized corridor showed changes in DWB compatible with histopathological and ultrasound feature changes in the rat tendinopathy model. The hindlimb SWBRs did not correspond with any tendinopathic changes.

Abstract
The purpose of this study was to investigate the dynamic changes of histopathology, biomechanical properties, echo intensity, and ultrasound features in a collagenase-induced tendinopathy model of rat Achilles tendons, and to examine the associations among biomechanical properties, echo intensity, and ultrasound features. Forty-two rats received an ultrasound-guided collagenase injection on their left Achilles tendons, and needle puncture on the right ones as the control. At four, eight, and twelve weeks post-injury, the tendons were examined via measurements of their biomechanical properties, histopathological and ultrasonographic characteristics. The injured tendons showed significantly higher histopathological scores, lower Young’s modulus, and higher ultrasound feature scores than the those of control ones throughout the study period. Up to week 12, all injured tendons showed defective healing. The neovascularization score had a significant negative linear association with the failure stress and Young’s modulus. Maximum normalized echo intensity had a significant positive linear association with maximum strain. Therefore, neovascularization and maximum normalized echo intensity are associated with mechanically altered tendinopathic tendons. Non-invasive ultrasound methodology, including echo intensity and ultrasound feature scores, may provide useful information about biomechanical properties of tendinopathic tendons.

Abstract
OBJECTIVE To determine the clinical efficacy of sonographically-guided percutaneous bone drilling of the lateral epicondyle (LE) for the treatment of patients with LE. METHODS We included 24 patients with LE who reported pain in this study. All patients underwent sonographically-guided percutaneous bone drilling of the lateral epicondyle. Follow-up sonography and physical examinations were performed 1, 3 and 6 months after the procedure. The outcome measures included sonographic findings, visual analogue scale (VAS) score, maximum voluntary grip strength (MVGS) and patient-related tennis elbow evaluation (PRTEE) score. RESULTS None of the patients had immediate complications during the procedure. The area of the extensor carpi radialis brevis (ECRB) tears decreased significantly at 1 month and declined gradually over the remaining 5 months of the study (p < 0.001). The mean pain VAS score was significantly lower at 6 months than preoperatively (respectively; p < 0.001). The mean MVGS increased significantly between pretreatment and 6 months post-treatment (p < 0.001), whereas the PRTEE score decreased significantly during the same period (p < 0.001). CONCLUSION Sonographically-guided percutaneous drilling is a quick and safe treatment option for LE that can be performed in an outpatient setting. KEY POINTS • Percutaneous drilling of the lateral condyle is effective for the treatment of LE. • The area of ECRB tears can be measured by US-guided saline injection. • US-guided percutaneous drilling is a quick and safe treatment option for LE.

Abstract
OBJECTIVE To explore the effect of acupuncture on common extensor tendon (CET) thickness in patients with lateral epicondylitis (LE). Additionally, to identify whether clinical and ultrasonographic changes showed any correlation. METHODS Forty-one patients were randomly assigned to acupuncture and control groups. Conventional treatment (rest, NSAİİ, bracing, exercise) methods for LE were applied to all patients. In addition to this, the acupuncture treatment was applied to the acupuncture group. The visual analog scale (VAS) for pain, the Duruoz Hand Index (DHI) for functioning of the affected limb, the pressure pain threshold, and CET thickness (via ultrasound imaging) were assessed before and end of the treatment in both groups. RESULTS The VAS and DHI scores in both groups decreased. The pressure pain threshold and CET thickness only demonstrated improvement in the acupuncture group. CONCLUSION These findings show that the CET thickness was reduced after 10 sessions of acupuncture treatment in LE patients.

Abstract
Background: Ultrasonography (US) of the common extensor tendon (CET) of the elbow is often part of the assessment of patients with lateral epicondylitis. This US assessment is currently based on general tendinopathy references and not well-defined US entities. Purpose: To describe CET thickness, color Doppler activity, and bony spurs on US in asymptomatic volunteers and to investigate the influence of sex, age, height, body mass index (BMI), weight, and elbow dominance on the measurements. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Tendon thickness, color Doppler activity, and bony spurs of the CET were measured sonographically in 264 adults (50% women) aged 20 to 96 years. Two different tendon-thickness measuring techniques were applied, labeled the “plateau measure” and the “1-cm measure.” Color Doppler activity was based on a 0 to 4 rating scale (negative, grades 0 and 1; positive, grades 2-4). A bony spur was defined as a bony outgrowth (≥0.3 mm) arising at the insertional site of the CET. Results: With both tendon-thickness measuring techniques, the CET in the dominant elbow was thicker than that in the nondominant elbow, and male tendons were thicker than female tendons (all P ≤ .03). In regression analysis, tendon thickness correlated with weight, color Doppler activity, and arm dominance for both measuring techniques in multiple regression analysis. In addition, the plateau measure correlated with height and the presence of bony spurs. No correlations were observed regarding BMI, sex, or age. Positive color Doppler activity was found in 9% of examined elbows, with no difference between the sexes regarding dominant versus nondominant elbows (all P ≥.20). Bony spurs were found to increase with age, from 23% for people in their 20s to 74% in people older than 70 years. Bony spurs were more common in the dominant elbow (P ≤ .01). Women had a higher prevalence of bony spurs than men, but only in the dominant elbow (P = .03). Conclusion: This study presents the US characteristics and normal values of the CET. In 264 asymptomatic participants, the CET was found to be thicker in men and in the dominant elbow. No difference in tendon thickness could be demonstrated with regard to different age groups. Color Doppler activity was found to be positive in nearly 1 of 10 asymptomatic subjects. Bony spurs were a common finding; they increased in prevalence with every decade in age and were considered part of the aging process. Normal variations in CET morphologic characteristics should therefore be considered when implementing US in trials and clinical practice.

Abstract
BACKGROUND Diagnostic ultrasound (US) is a commonly used imaging modality for visualising tendon pathology and morphology. In comparison to magnetic resonance imaging (MRI), diagnostic US is perceived to have a higher risk of error when evaluating tendon size. AIM To systematically assess the evidence regarding the Intra rater and Inter rater reliability of diagnostic US measurements of tendon size. DATA SOURCES Eight electronic databases were searched using an agreed set of keywords. Studies which investigated the reliability of tendon size (thickness or cross sectional area) using diagnostic US were eligible. RESULTS Combined Inter rater and Intra rater ICC values for tendon thickness ranged from 0.45 to 0.99. Combined Inter rater and Intra rater ICC values for tendon cross-sectional area (CSA) ranged from 0.58 to 0.92. Overall, Intra rater ICC values (0.59-0.99) were marginally higher than Inter rater values (0.45-0.99) across all tendon sites. Percentage co-efficient of variation (CV%) for tendon thickness and CSA ranged from 0 to 35% across all tendons. Percentage standard error of the mean SEM% values for tendon thickness ranged from 3.33% to 7.39%. CONCLUSIONS The findings of this review suggest diagnostic US measures of tendon size are reliable, both in terms of relative and absolute reliability. However, the findings must be considered in light of the presence of tendon abnormalities in a large percentage of asymptomatic populations.

Abstract
PURPOSE Rotator cuff (RC) tendinopathy has been widely ascribed to impingement of the supraspinatus tendon (SsT) in the subacromial space, measured as the acromiohumeral distance (AHD). Ultrasound (US) is suitable for measuring AHD and SsT thickness, but few reliability studies have been carried out in symptomatic populations, and interrater reliability is unconfirmed. This study aimed to examine the intrarater and interrater reliability of US measurements of AHD and SsT thickness in asymptomatic control subjects and patients with RC tendinopathy. METHODS Seventy participants were recruited and grouped as healthy controls (n = 25) and RC tendinopathy (n = 45). Repeated US measurements of AHD and SsT thickness were obtained by one rater in both groups and by two raters in the RC tendinopathy group. RESULTS Intrarater and interrater reliability coefficients were excellent for both measurements (intraclass correlation > 0.92), but the intrarater reliability was superior. The minimal detectable change values in the symptomatic group were 0.7 mm for AHD and 0.6 mm for SsT thickness for a single experienced examiner; the values rose to 1.2 mm and 1.3 mm, respectively, for the pair of examiners. CONCLUSIONS The results support the reliability of US for the measurement of AHD and SsT thickness in patients with symptomatic RC tendinopathy and provide minimal detectable change values for use in future research studies.

Abstract
Medial epicondylitis, often referred to as "golfer's elbow," is a common pathology. Flexor-pronator tendon degeneration occurs with repetitive forced wrist extension and forearm supination during activities involving wrist flexion and forearm pronation. A staged process of pathologic change in the tendon can result in structural breakdown and irreparable fibrosis or calcification. Patients typically report persistent medial-sided elbow pain that is exacerbated by daily activities. Athletes may be particularly symptomatic during the late cocking or early acceleration phases of the throwing motion. Nonsurgical supportive care includes activity modification, NSAIDs, and corticosteroid injections. Once the acute symptomology is alleviated, focus is turned to flexor-pronator mass rehabilitation and injury prevention. Surgical treatment via open techniques is typically reserved for patients with persistent symptoms.

ULTRASOUND IN MEDICINE & BIOLOGY 2015; 41:1592-1598. [PMID: 25748525 DOI: 10.1016/j.ultrasmedbio.2015.01.018] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/26/2014] [Revised: 01/10/2015] [Accepted: 01/21/2015] [Indexed: 06/04/2023]
Abstract
In individuals with lateral elbow tendinopathy, the thickness of the common lateral extensors tendon can be evaluated by musculoskeletal ultrasonography (MSU) for diagnostic and evaluative purposes. The reproducibility of these thickness measurements should be established before integrating it into daily practice. A test-retest design was used to determine the reproducibility of these measurements in the longitudinal and transverse planes. Seventy-three healthy participants were measured two times by two raters. Intra-class correlation coefficient values for inter-rater reliability for the longitudinal and transverse planes were 0.67 and 0.49. Intra-class correlation coefficient values for intra-rater reliability varied between 0.73 and 0.92. The smallest detectable change ranged from 0.50 to 0.78 mm and comprised 9.8%-16.3% of the mean thickness. MSU thickness measurement of the common lateral extensors tendon of the elbow has fair to excellent intra- and inter-rater reliability. Additionally, agreement is acceptable, which makes MSU a valuable tool for the evaluation of tendon thickness over time.

Abstract
Upper extremity pain in persons with spinal cord injury is a common cause of morbidity. Ultrasound of nerve, muscle, and tendon has the potential to become a valuable modality in assessing this population, and has the advantage of reduced health care costs, portability, and use in populations that cannot tolerate MRI. It has the potential to detect issues before the onset of significant morbidity, and preserve patient independence. Upper extremity ultrasound already has many studies showing its utility in diagnosis, and newer techniques have the potential to enhance its use in the diagnosis and management of musculoskeletal conditions.

Abstract
BACKGROUND The purpose of this study was to determine the diagnostic test accuracy of ultrasound for the detection of lateral epicondylitis. METHODS An electronic search of databases registering published (MEDLINE, EMBASE, CINAHL, AMED, Cochrane Library, ScienceDirect) and unpublished literature was conducted to January 2013. All diagnostic accuracy studies that compared the accuracy of ultrasound (index test) with a reference standard for lateral epicondylitis were included. The methodological quality of each of the studies was appraised using the QUADAS tool. When appropriate, the pooled sensitivity and specificity analysis was conducted. RESULTS Ten studies investigating 711 participants and 1077 elbows were included in this review. Ultrasound had variable sensitivity and specificity (sensitivity: 64%-100%; specificity: 36%-100%). The available literature had modest methodological quality, and was limited in terms of sample sizes and blinding between index and reference test results. CONCLUSIONS There is evidence to support the use of ultrasound in the detection of lateral epicondylitis. However, its accuracy appears to be highly dependent on numerous variables, such as operator experience, equipment and stage of pathology. Judgement should be used when considering the benefit of ultrasound for use in clinical practice. Further research assessing variables such a transducer frequency independently is specifically warranted. LEVEL OF EVIDENCE Level II.

Abstract
Background Ultrasound is considered a reliable, widely available, non-invasive and inexpensive imaging technique for assessing soft tissue involvement in Lateral epicondylalgia. Despite the number of diagnostic studies for Lateral Epicondylalgia, there is no consensus in the current literature on the best abnormal ultrasound findings that confirm lateral epicondylalgia. Methods Eligible studies identified by searching electronic databases, scanning reference lists of articles and chapters on ultrasound in reference books, and consultation of experts in sonography. Three reviewers (VCDIII, KP, KW) independently searched the databases using the agreed search strategy, and independently conducted all stages of article selection. Two reviewers (VCDIII, KP) then screened titles and abstracts to remove obvious irrelevance. Potentially relevant full text publications which met the inclusion criteria were reviewed by the primary investigator (VCDIII) and another reviewer (CGS). Results Among the 15 included diagnostic studies in this review, seven were Level II diagnostic accuracy studies for chronic lateral epicondylalgia based on the National Health and Medical Research Council Hierarchy of Evidence. Based from the pooled sensitivity of abnormal ultrasound findings with homogenous results (p > 0.05), the hypoechogenicity of the common extensor origin has the best combination of diagnostic sensitivity and specificity. It is moderately sensitive [Sensitivity: 0.64 (0.56-0.72)] and highly specific [Specificity: 0.82 (0.72-0.90)] in determining elbows with lateral epicondylalgia. Additionally, bone changes on the lateral epicondyle [Sensitivity: 0.56 (0.50-0.62)] were moderately sensitive to chronic LE. Conversely, neovascularity [Specificity: 1.00 (0.97-1.00)], calcifications [Specificity: 0.97 (0.94-0.99)] and cortical irregularities [Specificity: 0.96 (0.88-0.99)] have strong specificity for chronic lateral epicondylalgia. There is insufficient evidence supporting the use of Power Doppler Ultrasonogrophy, Real-time Sonoelastography and sonographic probe-induced tenderness in diagnosing LE. Conclusions The use of Gray-scale Ultrasonography is recommended in objectively diagnosing lateral epicondylalgia. The presence of hypoechogenicity and bone changes indicates presence of a stressed common extensor origin-lateral epicondyle complex in elbows with lateral epicondylalgia. In addition to diagnosis, detection of these abnormal ultrasound findings allows localization of pathologies to tendon or bone that would assist in designing an appropriate treatment suited to patient’s condition.

Abstract
OBJECTIVE The purpose of this video article is to aid examiners in clinical practice in identifying intraarticular and extraarticular pathologic changes in the elbow, including intraarticular structures, fluid in the joint, arthritis, synovitis, and loose bodies. CONCLUSION Common pathologic findings can be identified with a standardized ultrasound technique based on landmarks, and intraarticular injection and aspiration, dynamic imaging, and ulnar stress maneuvers can be performed. Extraarticular pathologic findings are evaluated in an approach based on quadrants.

Abstract
The applications of ultrasound in managing the clinical care of athletes have been expanding over the past decade. This review provides an analysis of the research that has been published regarding the use of ultrasound in athletes and focuses on how these emerging techniques can impact the clinical management of athletes by sports medicine physicians. Electronic database literature searches were performed using the subject terms 'ultrasound' and 'athletes' from the years 2003 to 2012. The following databases were searched: PubMed, Web of Science, Cochrane Library, CINAHL, and SPORTDiscus™. The search produced 617 articles in total, with a predominance of articles focused on cardiac and musculoskeletal ultrasound. 266 of the studies involved application of ultrasound in evaluating the cardiovascular properties of athletes, and 151 studies involved musculoskeletal ultrasound. Other applications of ultrasound included abdominal, vascular, bone density and volume status. New techniques in echocardiography have made significant contributions to the understanding of the physiological changes that occur in the athlete's heart in response to the haemodynamic stress associated with different types of activity. The likely application of these techniques will be in managing athletes with hypertrophic cardiomyopathy, and the techniques are near ready for application into clinical practice. These techniques are highly specialized, however, and will require referral to dedicated laboratories to influence the clinical management of athletes. Investigation of aortic root pathology and pulmonary vascular haemodynamics are also emerging, but will require additional studies with larger numbers and outcomes analysis to validate their clinical utility. Some of these techniques are relatively simple, and thus hold the potential to enter clinical management in a point-of-care fashion. Musculoskeletal ultrasound has demonstrated a number of diagnostic and therapeutic techniques applicable to pathology of the shoulder, elbow, wrist, hand, hip, knee and ankle. These techniques have been applied mainly to the management of impingement syndromes, tendinopathies and arthritis. Many of these techniques have been validated and have entered clinical practice, while more recently developed techniques (such as dynamic ultrasound and platelet-rich plasma injections) will require further research to verify efficacy. Research in musculoskeletal ultrasound has also been helpful in identifying risk factors for injury and, thus, serving as a focus for developing interventions. Research in abdominal ultrasound has investigated the potential role of ultrasound imaging in assessing splenomegaly in athletes with mononucleosis, in an attempt to inform decisions and policies regarding return to play. Future research will have to demonstrate a reduction in adverse events in order to justify the application of such a technique into policy. The role of ultrasound in assessing groin pain and abdominal pain in ultraendurance athletes has also been investigated, providing promising areas of focus for the development of treatment interventions and physical therapy. Finally, preliminary research has also identified the role of ultrasound in addressing vascular disease, bone density and volume status in athletes. The potential applications of ultrasound in athletes are broad, and continuing research, including larger outcome studies, will be required to establish the clinical utility of these techniques in the care of athletes.
