Sonographic evaluation of the distal iliopsoas tendon using a new approach

EURO-MUSCULUS/USPRM Dynamic Ultrasound Protocols for (Adult) Hip

ABSTRACT

In this dynamic scanning protocol, ultrasound assessment of the adult hip is described using different maneuvers for various conditions. Real-time patient examination and ultrasound scanning videos are coupled for convenience as well as for better insight. The text covers the common conditions around the hip where especially dynamic ultrasound scanning provides valuable information in addition to static imaging. The protocol is prepared by an international consensus of several experts in the field of musculoskeletal ultrasound.

Evaluation of the Lower Trapezius Muscle Using Ultrasound Panoramic View (a Novel Approach): An Intra- and Inter-Rater Reliability Study

The panoramic view ultrasound remains uncommon in clinical practice, probably because of its difficulty, high-cost, and lack of research. Morphological changes in muscles have been demonstrated to be related to symptomatology and provide data of interest for clinical assessment. Thus, the aim of this study was to evaluate the measurement reliability of the length of the lower trapezius muscle with the panoramic view ultrasound using a novel tool, SIG_VIP^®. Twenty healthy volunteers were measured by two expert sonographers using the SIG_VIP^® tool with a novel approach. Statistical analyses were performed with the R software. The intraclass correlation coefficient (ICC), standard error of measurement (SEM), minimal detectable change (MDC), and Bland-Altman plots were calculated. All the results indicated good intra-rater reliability (ICC_3,1, 0.92 to 0.96; SEM, 0.59 to 0.85; MDC, 1.64 to 2.35) and inter-rater reliability (ICC_3,2, 0.84 to 0.89; SEM, 1.22 to 1.53; MDC, 3.39 to 4.25). The novel system used with the described methodology can reliably measure the length of the inferior fibers of the trapezius muscle. Further research must be conducted to evaluate the reliability in patients and how pathology is related to the length of the lower trapezius muscle.

non-arthroplasty iliopsoas impingement in athletes: a narrative literature review

INTRODUCTION

Iliopsoas impingement occurs secondary to a tight iliopsoas tendon that causes impingement during movement. This review presents current aspects regarding the diagnosis of iliopsoas impingement and also exposes the readers to the possible anatomic and clinical variations together with the available treatment options.

METHODS

We conducted a narrative literature review with regard to non-arthroplasty iliopsoas impingement.

RESULTS

Iliopsoas impingement is characterised by a distinct pattern of labral pathology, with anteriorly localised labral damage, that does not extend to the anterosuperior portion of the acetabulum. Anterior groin pain and intermittent catching, snapping or popping of the hip are common symptoms. Non-specific focal tenderness is often found over the iliopsoas tendon at the level of the anterior aspect of the joint. The 'C-sign' and Impingment test are usually positive. Dynamic ultrasonography is also useful for confirming the diagnosis. Initial management of painful iliopsoas impingement should be conservative. When patients continue to have pain, an ultrasound-guided injection can provide relief and predict the response to the surgical release. For patients who have recurrent pain after local injection of steroids, arthroscopic release has shown to achieve effective results.

CONCLUSIONS

Although different treatment options for iliopsoas impingement are emerging, the current standard of therapy is conservative followed by an arthroscopic tenotomy if necessary. Young adult hip surgeons should always keep this differential in mind in a patient presenting with groin pain and mechanical symptoms.

US Assessment of Sports-related Hip Injuries

Traumatic and overuse hip injuries occur frequently in amateur and professional athletes. After clinical assessment, imaging plays an important role in diagnosis and in defining care management of these injuries. Ultrasonography (US) is being increasingly used in assessment of hip injuries because of the wide availability of US machines, the lower cost, and the unique real-time imaging capability, which allows both static and dynamic evaluation as well as guidance of point-of-care interventions such as fluid aspiration and steroid injection. Accurate diagnosis of hip injuries is often challenging, given the complex soft-tissue anatomy of the hip and the wide spectrum of injuries that can occur. To conduct a skillful US evaluation of hip injuries, physicians must have pertinent knowledge of the normal anatomy and should make judicious use of surface anatomy landmarks while using a compartmentalized diagnostic approach. In this article, common sports-related injuries of the anterior, lateral, and posterior hip compartments are discussed. This review includes assessment of joint effusion, acetabular labral tear, acute and chronic tendon injuries including tendinopathy, partial and full-thickness tears, snapping hip syndromes, relevant US-guided procedures, and some other conditions such as Morel-Lavallée lesion and perineal nodular induration. Principles of care management and current knowledge on imaging findings that may affect return to activity are also presented. Using an oriented US examination technique and having knowledge of the normal hip anatomy will help physicians characterize US findings of common sports-related hip injuries and make accurate diagnoses.
