Background The indication for surgery is justified by an expected improvement for the patient. To evaluate the probability and extent of individual postoperative patient benefit, the surgeon needs to elaborate numerous parameters of potential relevance for the outcome beyond his key competence, that is the technical dimension of the operation. Despite the highest medical standards, individual postoperative satisfaction with surgery is highly variable, even in cases with a technically good result. The aim of the present study was to investigate the individual predictability of postoperative pain and satisfaction in patients with elective musculoskeletal surgery...

BACKGROUND: Higher body mass index (BMI) is associated with difficulty in obtaining imaging studies. While there is a small body of literature regarding the relationship between fluoroscopy time and BMI during injections for pain management, this has not been studied for intraarticular (IA) hip injections. Further, in academic training centers, trainee involvement may affect this relationship. OBJECTIVE: To determine the relationship between BMI and fluoroscopy time during IA hip injections, both with and without involvement of a trainee...

AIMS: The aim of our study is to demonstrate that increased T2 signal on MRI could be due to intraneural vessels in asymptomatic individuals, and may therefore be a normal finding. METHODS: An initial anatomic cadaveric study was undertaken to gain a better understanding of the vascular supply of the proximal sciatic nerve. Secondly, a retrospective study of MR imaging of patients without sciatic symptoms was performed to assess the prevalence of intraneural vessels, defined as hyperintensity on at least 3 consecutive slices on both T2 and Gadolinium enhanced T1 weighted imaging, visible on routine MSK pelvic imaging...

Musculoskeletal pathologies in the pelvis encompass a wide variety of lesions including femoroacetabular impingement, athletic pubalgia, ischiofemoral impingement, and apophyseal avulsion injuries. Magnetic resonance imaging is the noninvasive imaging modality of choice for the diagnosis and management of these lesions. In this article, the authors discuss the nonneoplastic musculoskeletal lesions in the pelvis, with illustrations and relevant case examples.

Neuromusculoskeletal disorders affecting walking ability are often difficult to manage, in part due to limited understanding of how a patient's lower extremity muscle excitations contribute to the patient's lower extremity joint moments. To assist in the study of these disorders, researchers have developed electromyography (EMG) driven neuromusculoskeletal models utilizing scaled generic musculoskeletal geometry. While these models can predict individual muscle contributions to lower extremity joint moments during walking, the accuracy of the predictions can be hindered by errors in the scaled geometry...

Bone-soft tissue friction is an important factor affecting several musculoskeletal disorders, frictional syndromes and the ability of a bone fracture to heal. However, this parameter is difficult to determine using non-invasive imaging modalities, especially in clinical settings. Ultrasound axial shear strain elastography is a non-invasive imaging modality that has been used in the recent past to estimate the bonding between different tissue layers. As most elastography methods, axial shear strain elastography is primarily used in soft tissues...

Face recognition is an apparently straightforward but, in fact, complex ability, encompassing the activation of at least visual and somatosensory representations. Understanding how identity shapes the interplay between these face-related affordances could clarify the mechanisms of self-other discrimination. To this aim, we exploited the so-called "face inversion effect" (FIE), a specific bias in the mental rotation of face images (of other people): with respect to inanimate objects, face images require longer time to be mentally rotated from the upside-down...

Juvenile idiopathic arthritis (JIA) and osteoarticular infection can cause nonspecific articular and periarticular complaints in children. Although contrast material-enhanced magnetic resonance imaging is the reference standard imaging modality, musculoskeletal ultrasonography (US) is emerging as an important adjunct imaging modality that can provide valuable information relatively quickly without use of radiation or the need for sedation. However, diagnostic accuracy requires a systemic approach, familiarity with various US techniques, and an understanding of maturation-related changes...

The WHO reports that one of the major chronic conditions affecting the elderly worldwide is musculoskeletal disorders that are associated with long-term pain and disability. Considering the healthcare needs of the elderly (i.e. comprehensive, accessible, efficient) and the advantages of ultrasound (US) use (patient-friendly, convenient, cost-effective, and does not require exposure to radiation or magnetic fields), there seems to be a 'gap' in the actual clinical practice. In this paper, we aimed to highlight the potential value of US imaging in the management of the elderly with a wide spectrum of musculoskeletal conditions (degenerative/rheumatic joint diseases, falls/trauma, nursing care, peripheral nerve problems, sarcopenia, and interventions)...
