RESUMEN
The purpose of this scoping review was to identify possible chondrotoxic effects caused by drugs usually used for intra-articular injections. PubMed, Scopus, Web of Science and Cochrane were searched. Inclusion criteria required randomized controlled trials written in English that evaluate the toxic effect that damages the cartilage. The literature search resulted in 185 unique articles. 133 full-text articles were screened for inclusion, of which 65 were included. Corticosteroids, with the exception of triamcinolone, along with local anaesthetics, potentially excluding ropivacaine and liposomal bupivacaine, and nonsteroidal anti-inflammatory drugs, exhibited insufficient safety profiles to warrant casual use in clinical settings. Hyaluronic acid, on the other hand, appears to demonstrate safety while also mitigating risks associated with concurrent compounds, thereby facilitating therapeutic combinations. Additionally, there remains a paucity of data regarding platelet-rich plasma, necessitating further evaluation of its potential efficacy and safety. Overall, it seems that results are significantly influenced by the dosage and frequency of injections administered, observed in both human and animal studies.

Over the past decade, there has been a notable increase in research focused on ultrasound imaging of thoracolumbar fascia (TLF). Nevertheless, published papers' results about the application of US imaging in TLF examination are still sparse. Background and Objevtives: Hence, this systematic review was performed aiming to firstly investigate the use and the methodology of ultrasound imaging to assess pathologic and healthy TLF. Secondarily, we aim to assess intra- and inter-observer reproducibility of US imaging in TLF assessment. Materials and Methods: The search was done on PubMed and Web of Science database from inception to April 2024. Furthermore, the references of included papers were thoroughly checked to find eligible publications. The MeSH keywords used were: "Thoracolumbar fascia", "Ultrasound Imaging", "Ultrasound", "Ultrasonography", and "Ultrasound examination". Results: Studies were aimed primarily at TLF diagnosis, treatment monitoring, or evaluating movement-related changes, underscoring the diverse clinical applications. The US parameters assessed included TLF thickness, echogenicity, stiffness, deformation, shear strain, and displacement, providing comprehensive insights into TLF features. Conclusions: Advanced US imaging holds promise as a reliable tool in musculoskeletal assessment, offering insights into TLF pathology/disfunction, treatment outcomes, and movement dynamics.

Nerve/tendon snapping can occur due to their sudden displacement during the movement of an adjacent joint, and the clinical condition can really be painful. It can actually be challenging to determine the specific anatomic structure causing the snapping in various body regions. In this sense, ultrasound examination, with all its advantages (especially providing dynamic imaging), appears to be quite promising. To date, there are no comprehensive reviews reporting on the use of dynamic ultrasound examination in the diagnosis of nerve/tendon snapping. Accordingly, this article aims to provide a substantial discussion as to how US examination would contribute to 'seeing' and 'hearing' these pathologies' different maneuvers/movements.

In the context of long-distance space travel, managing medical conditions presents unique challenges due to communication delays. Consequently, onboard physicians must possess proficiency in diagnostic tools such as ultrasound, which has demonstrated its efficacy in the Space. However, there is a notable lack of comprehensive discussion regarding its effectiveness in handling medical scenarios in the Space. This bibliometric and systematic review aims to provide an updated analysis of the evidence supporting the role of ultrasound imaging in diagnosing medical conditions within microgravity environments.
RESUMEN
The superior extensor ankle retinaculum (SEAR), a transversely fascial thickening positioned above the tibia-talar joint, serves as a crucial anatomical structure in ankle stability. The purpose of this study was to measure and compare by ultrasound (US) imaging the bilateral thickness and echogenicity of SEAR in football players with previous multiple ankle sprains (group 1) and healthy volunteers (group 2). A cross-sectional study was performed using ultrasound imaging to measure longitudinal and transversal axes using a new protocol in a sample of 50 subjects: 25 football players with previous multiple ankle sprains and 25 healthy subjects. The findings for SEAR thickness revealed statistically significant differences for both axes (p = 0.0011 and p = 0.0032) between the healthy side and the previously sprained side, and with the corresponding side of group 2 (p = 0.003 and p = 0.004). Moreover, in group 1, regarding the ROI echogenicity, a statistically significant difference was found between the sides (p = 0.0378). These findings suggest that the football players with previous ankle sprains showed a thicker and inhomogeneous SEAR on the sprain side, unveiling a remodeling of this structure compared to the other side and to the healthy volunteers. In these athletes, during US examination, one needs to keep "a US eye" on side-to-side SEAR comparisons.
RESUMEN
Ultrasound imaging of the musculoskeletal system is paramount for physicians of different specialties. In recent years, its use has become the extension of physical examinations like using a "magnifying glass". Likewise, the eventual concept has naturally and spontaneously evolved to a "fusion" of classical physical examination and static/dynamic ultrasound imaging of the musculoskeletal system. In this regard, we deem it important to explore the current use/awareness regarding 'ultrasound examination', and to better provide insight into understanding future research spots in this field. Accordingly, this study aimed to search the global/research status of 'ultrasound examination' of the musculoskeletal system based on bibliometric and visualized analysis.

Flexibility and dynamic perspective of ultrasound imaging allow for a targeted/focused examination, yielding extra find-ings. Sonopalpation - also referred as sono-Tinel for nerves - is one of those particular features of ultrasound examination whereby the ultrasound probe is actively 'manipulated'. It is paramount to ascertain the painful structure/pathology during the evaluation of a patient and it is not possible with other imaging techniques other than ultrasonography. In this aspect, the cur-rent review aims to provide an analysis of the literature regarding the use of sonopalpation for clinical and research purposes respectively.

The thoracolumbar fascia (TLF) plays an important role in lower back pain (LBP). Recent studies have revealed an association between increases in TLF thickness and reduced TLF gliding in patients with LBP. The purpose of this study was to measure and compare by ultrasound (US) imaging the thickness of the TLF at the bilateral L3 level of the lumbar spine in the longitudinal and transverse axes in chronic non-specific LBP and in healthy subjects. A cross-sectional study was performed using US imaging to measure the longitudinal and transverse axes with a new protocol in a sample of 92 subjects: 46 chronic non-specific LBP patients and 46 healthy participants. The findings for TLF thickness revealed statistically significant differences (p < 0.05) in the longitudinal and transverse axes between the two groups. Moreover, in the healthy group, a statistically significant difference was found between the longitudinal and transverse axes (p = 0.001 for left and p = 0.02 for right), which was not evident in the LBP patients. These findings suggest that the LBP patients lost anisotropy of the TLF, with it becoming homogeneously thicker and losing adaptability in the transversal direction. The US imaging evaluation suggests that TLF thickness behavior points out altered fascial remodelling compared to healthy subjects, a sort of "frozen back".
RESUMEN
Crural fascia (CF) and plantar fascia (PF) are biomechanically crucial in the gait and in the proprioception, particularly in the propulsion phase of the foot during the gait cycle and in the dissipation of forces during weight-bearing activities. Recent studies have revealed an association between increases in PF thickness and diabetes. The purpose of this study was to measure and compare by ultrasound (US) imaging the thickness of the CF and PF at different regions/levels in chronic Charcot diabetic foot patients (group 1) and in healthy volunteers (group 2). A cross-sectional study was performed using US imaging to measure the CF with Pirri et al.'s protocol and PF with a new protocol in a sample of 31 subjects (15 patients and 16 healthy participants). The findings for CF and PF revealed statistically significant differences in the poster region of CF (Post 1: group 1 vs. group 2: p = 0.03; Post 2: group 1 vs. group 2: p = 0.03) and in PF at two different levels (PF level 1: group 1 vs. group 2: p < 0.0001; PF level 2: group 1 vs. group 2: p < 0.0001). These findings suggest that chronic Charcot diabetic foot patients have CF and PF thicker compared to healthy volunteers. The US examination suggests that fascial thicknesses behavior in these patients points out altered fascial remodeling due to diabetes pathology and biomechanical changes.
RESUMEN
Intramuscular hemangiomas are benign vascular lesions, often misdiagnosed due to unfamiliarity. They are rare (but not very rare) causes of musculoskeletal pain, and diagnosing these tumors may be challenging because of their pertinent nonspecific symptomatology. Herein, as a convenient imaging tool, ultrasound examination appears to be an important initial method to scan for these lesions after the clinical examination. To date, there are no studies that examined the state-of-the-art in regard to the use of ultrasound imaging in the diagnosis of intramuscular hemangiomas. Accordingly, a literature search was performed using PubMed and Web of Science with the purpose to provide a conceptual understanding and awareness as regards the importance/utility of ultrasound imaging as a first step diagnostic tool for intramuscular hemangiomas at different muscles' locations.

Hyaluronan (HA) has complex biological roles that have catalyzed clinical interest in several fields of medicine. In this narrative review, we provide an overview of HA aggregation, also called densification, in human organs. The literature suggests that HA aggregation can occur in the liver, eye, lung, kidney, blood vessel, muscle, fascia, skin, pancreatic cancer and malignant melanoma. In all these organs, aggregation of HA leads to an increase in extracellular matrix viscosity, causing stiffness and organ dysfunction. Fibrosis, in some of these organs, may also occur as a direct consequence of densification in the long term. Specific imaging evaluation, such dynamic ultrasonography, elasto-sonography, elasto-MRI and T1ρ MRI can permit early diagnosis to enable the clinician to organize the treatment plan and avoid further progression of the pathology and dysfunction.

Ultrasound (US) imaging is increasingly the most used tool to measure the thickness of superficial and deep fasciae, but there are still some doubts about its reliability in this type of measurement. The current study sets out to assess the inter-rater and intra-rater reliability of US measurements of superficial and deep fasciae thicknesses in the arm and forearm. The study involved two raters: the first (R1) is an expert in skeletal-muscle US imaging and, in particular, the US assessment of fasciae; the second (R2) is a radiologist resident with 1 year's experience in skeletal-muscle US imaging. R2, not having specific competence in the US imaging of fasciae, was trained by R1. R1 took US images following the protocol by Pirri et al. 2021, and the US-recorded images were analyzed separately by the two raters in different sessions. Each rater measured both types of fasciae at different regions and levels of the arm and forearm. Intra- and inter-rater reliability was excellent for the deep fascia and good and excellent for the superficial fascia according to the different regions/levels (for example for the anterior region of the arm: deep fascia: Ant 1: ICC2,2 = 0.95; 95% CI = 0.81-0.98; superficial fascia: Ant 1: ICC2,2 = 0.85, 95% CI = 0.79-0.88). These findings confirm that US imaging is a reliable and cost-effective tool for evaluating both fasciae, superficial and deep.
RESUMEN
The superficial fascia has received much attention in recent years due to its important role of compartmentalizing the subcutaneous tissue. Ultrasound (US) imaging, owing to its high definition, provides the possibility of better visualizing and measuring its thickness. The aim of this study was to measure and compare, with US imaging, the thickness of superficial fascia in the arm and forearm in different regions/levels. An observational study has been performed using US imaging to measure superficial fascia thickness in the anterior and posterior regions at different levels in a sample of 30 healthy volunteers. The results for superficial fascia thickness revealed statistically significant differences (p < 0.0001) in the arm between the anterior and posterior regions; in terms of forearm, some statistically significant differences were found between regions/levels. However, in the posterior region/levels of the arm, the superficial fascia was thicker (0.53 ± 0.10 mm) than in the forearm (0.41 ± 0.10 mm); regarding the anterior regions/levels, the superficial fascia of the arm (0.40 ± 0.10 mm) was not statistically different than the forearm (0.40 ± 0.12 mm). In addition, the intra-rater reliability was good (ICC2,k: 0.88). US helps to visualize and assess the superficial fascia inside the subcutaneous tissue, improving the diagnosis of fascial dysfunction, and one of the Us parameters to reliably assess is the thickness in different regions and levels.

Wound healing is an intricate, dynamic process, in which various elements such as hyperglycemia, neuropathy, blood supply, matrix turnover, wound contraction, and the microbiome all have a role in this "out of tune" diabetic complex symphony, particularly noticeable in the complications of diabetic foot. Recently it was demonstrated that the fasciae have a crucial role in proprioception, muscular force transmission, skin vascularization and tropism, and wound healing. Indeed, the fasciae are a dynamic multifaceted meshwork of connective tissue comprised of diverse cells settled down in the extracellular matrix and nervous fibers; each constituent plays a particular role in the fasciae adapting in various ways to the diverse stimuli. This review intends to deepen the discussion on the possible fascial role in diabetic wounds. In diabetes, the thickening of collagen, the fragmentation of elastic fibers, and the changes in glycosaminoglycans, in particular hyaluronan, leads to changes in the stiffness, gliding, and the distribution of force transmission in the fasciae, with cascading repercussions at the cellular and molecular levels, consequently feeding a vicious pathophysiological circle. A clear scientific perception of fascial role from microscopic and macroscopic points of view can facilitate the identification of appropriate treatment strategies for wounds in diabetes and create new perspectives of treatment.
