Ultrasound-guided injection of the achilles paratenon: A cadaveric investigation. Foot Ankle Surg 2024; 30:313-318. [PMID: 38296758 DOI: 10.1016/j.fas.2024.01.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 09/06/2023] [Accepted: 01/13/2024] [Indexed: 02/02/2024]
Abstract
BACKGROUND Injections around the Achilles tendon (AT) are commonly performed in clinical practice to manage non-insertional Achilles tendinopathy, but the presence/distribution of the injectate with relation to its sheath has not been assessed specifically. Accordingly, the aim of this cadaveric investigation was to demonstrate the feasibility of Achilles paratenon injection under ultrasound guidance - by confirming the exact needle positioning as well as the dye distribution inside the paratenon lumen. METHODS A descriptive laboratory study with three human cadaveric specimens (one fresh cadaver and two cadavers embalmed using the Fix for Life (F4L) method) was performed in a tertiary-care academic institution. The interventional technique and the related anatomical findings were illustrated. During the injection, the needle was advanced inside the Achilles paratenon under ultrasound guidance i.e. in-plane medial-to-lateral approach. With the objective to confirm its correct placement, the needle was kept in situ on the right AT of the fresh cadaver. Likewise, to demonstrate the location of the dye inside the lumen of Achilles paratenon, the other five ATs - four on the embalmed cadavers and one on the fresh cadaver - were injected with 5 mL of green color dye. After removal of the needle, a layer-by-layer anatomical dissection was performed on all three cadavers. RESULTS On the right AT of the fresh cadaver, the position of the needle's tip within the Achilles paratenon was confirmed. Accurate placement of the dye inside the paratenon lumen was confirmed in four (80%) ATs, one of the fresh and three of the embalmed cadavers. No spread inside the crural fascia compartment or between the AT and the Kager's fat pad was observed. Herewith, unintentional spilling of the dye within the superficial soft tissues of the posterior leg was reported in the left AT of one of the two embalmed cadavers (20%). CONCLUSIONS Ultrasound-guided injection using the in-plane, medial-to-lateral approach can accurately target the lumen of Achilles paratenon.

Taurine reduces the risk for metabolic syndrome: a systematic review and meta-analysis of randomized controlled trials. Nutr Diabetes 2024; 14:29. [PMID: 38755142 PMCID: PMC11099170 DOI: 10.1038/s41387-024-00289-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 04/26/2024] [Accepted: 05/01/2024] [Indexed: 05/18/2024] Open
Abstract
BACKGROUND Metabolic syndrome (MetS) is a cluster of interconnected risk factors that significantly increase the likelihood of cardiovascular disease and type 2 diabetes. Taurine has emerged as a potential therapeutic agent for MetS. This meta-analysis of randomized controlled trials (RCTs) aimed to evaluate the effects of taurine supplementation on MetS-related parameters. METHODS We conducted electronic searches through databases like Embase, PubMed, Web of Science, Cochrane CENTRAL, and ClinicalTrials.gov, encompassing publications up to December 1, 2023. Our analysis focused on established MetS diagnostic criteria, including systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), triglyceride (TG), and high-density lipoprotein cholesterol (HDL-C). Meta-regression explored potential dose-dependent relationships based on the total taurine dose administered during the treatment period. We also assessed secondary outcomes like body composition, lipid profile, and glycemic control. RESULTS Our analysis included 1024 participants from 25 RCTs. The daily dosage of taurine in the studies ranged from 0.5 g/day to 6 g/day, with follow-up periods varying between 5 and 365 days. Compared to control groups, taurine supplementation demonstrated statistically significant reductions in SBP (weighted mean difference [WMD] = -3.999 mmHg, 95% confidence interval [CI] = -7.293 to -0.706, p = 0.017), DBP (WMD = -1.509 mmHg, 95% CI = -2.479 to -0.539, p = 0.002), FBG (WMD: -5.882 mg/dL, 95% CI: -10.747 to -1.018, p = 0.018), TG (WMD: -18.315 mg/dL, 95% CI: -25.628 to -11.002, p < 0.001), but not in HDL-C (WMD: 0.644 mg/dl, 95% CI: -0.244 to 1.532, p = 0.155). Meta-regression analysis revealed a dose-dependent reduction in DBP (coefficient = -0.0108 mmHg per g, p = 0.0297) and FBG (coefficient = -0.0445 mg/dL per g, p = 0.0273). No significant adverse effects were observed compared to the control group. CONCLUSION Taurine supplementation exhibits positive effects on multiple MetS-related factors, making it a potential dietary addition for individuals at risk of or already experiencing MetS. Future research may explore dose-optimization strategies and potential long-term benefits of taurine for MetS management.

A systematic review on sonoelastography for rotator-cuff post-repair assessment. Asian J Surg 2024; 47:2097-2105. [PMID: 38383203 DOI: 10.1016/j.asjsur.2024.02.094] [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: 10/05/2023] [Revised: 12/02/2023] [Accepted: 02/02/2024] [Indexed: 02/23/2024] Open
Abstract
Surgical repair of rotator cuff tears is performed routinely; however, the risks of re-tears and the associated consequences are significant. Sonoelastography, an imaging modality that evaluates the mechanical properties of tissues, can examine the dynamic transitions in rotator cuff stiffness following retear and investigate the relationship between these changes and the occurrences of retears. This systematic review aimed to summarize the role of perioperative sonoelastography in repaired rotator cuffs. A comprehensive search of the PubMed, Embase, and Cochrane databases was conducted, covering studies published until June 19, 2023. The Newcastle-Ottawa scale was used for quality assessment. The key information extracted from each study included the injury/surgery type, follow-up duration, sonoelastography mode, and main sonoelastographic findings. Eleven eligible studies comprising 355 patients were included. All studies focused on supraspinatus muscles and tendons with previous arthroscopic repairs. During the postoperative 1st - 6th months, muscle stiffness increased in the supraspinatus and decreased in the ipsilateral deltoid. Failure to recover supraspinatus muscle elasticity might be indicative of potential tendon re-tear; however, it is imperative to first establish correlations with other imaging modalities. Conflicting findings have been observed regarding stiffening or softening of the supraspinatus tendon after surgical repair. The preoperative stiffness of the supraspinatus tendon did not correlate with postoperative tendon integrity or function.

Pictorial Essay on Ultrasound and Magnetic Resonance Imaging of Paraspinal Muscles for Myofascial Pain Syndrome. Life (Basel) 2024; 14:499. [PMID: 38672769 PMCID: PMC11051048 DOI: 10.3390/life14040499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 04/05/2024] [Accepted: 04/09/2024] [Indexed: 04/28/2024] Open
Abstract
The paraspinal muscles of the cervical, thoracic, and lumbar spine are important pain generators because muscle strains or myofascial pain syndrome caused by trigger points are common during clinical practice. Ultrasonography is the most convenient imaging tool for evaluating these muscles due to its advantages, such as providing good delineation of soft tissues, easy accessibility, and zero radiation. Additionally, ultrasound can serve as a useful guiding tool for paraspinal muscle intervention to prevent inadvertent injuries to vital axial neurovascular structures. This pictorial essay presents ultrasound scanning protocols for the paraspinal and other associated muscles as well as a discussion of their clinical relevance. Axial magnetic resonance imaging has also been used to elucidate reciprocal anatomy. In conclusion, ultrasound imaging proves to be a valuable tool that facilitates the differentiation of individual paraspinal muscles. This capability significantly enhances the precision of interventions designed to address myofascial pain syndrome.

Abstract
OBJECTIVE This systematic review and meta-analysis aimed to evaluate the influence of core muscle training (CMT) on throwing ball velocity among overhead throwing athletes. DESIGN A literature search was performed from inception to July 2023 for randomized controlled trials (RCTs) investigating the effects of CMT on overhead throwing ball velocity. The primary outcome was the change in standing throwing ball velocity. The secondary outcome focused on the enhancement of step/jump throwing ball velocity. RESULTS Seven RCTs were included, revealing a significant improvement in standing throwing ball-velocity in the group undergoing CMT (Hedges' g = 0.701, 95% confidence interval [CI] = 0.339 to 1.063, p < 0.001). Longer treatment duration and a higher frequency of CMT sessions per week contributed to improved standing throwing ball velocity. However, CMT did not show significant benefits for step (Hedge's g = 0.463, 95% CI = -0.058 to 0.985, p = 0.082) and jump throwing ball-velocity (Hedges' g = 0.550, 95% CI = -0.051 to 1.152, p = 0.073). CONCLUSION CMT significantly enhanced standing ball throwing velocity. However, its effect on step/jump-throwing ball velocity was less certain. Further research is needed to explore the impact of CMT (especially its long-term effects) on throwing ball velocity.

Effectiveness of Lumbar Segmental Stabilization Exercises in Managing Disability and Pain Intensity Among Patients with Lumbar Spondylolysis and Spondylolisthesis: A Systematic Review and Meta-analysis of Randomized Controlled Trials. Spine (Phila Pa 1976) 2024:00007632-990000000-00621. [PMID: 38514931 DOI: 10.1097/brs.0000000000004989] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 03/06/2024] [Indexed: 03/23/2024]
Abstract
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVE This study aims to assess the effectiveness of lumbar segmental stabilization exercises (LSSE) in managing spondylolysis and spondylolisthesis. SUMMARY OF BACKGROUND DATA Spondylolysis and spondylolisthesis are spinal disorders associated with lumbar segmental instability. LSSE have shown positive effects in treating these conditions; however, systematic reviews and meta-analyses are lacking. METHODS A systematic search adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, including studies from the inception of the databases used up to January 2024, was conducted. Disability improvement and pain intensity change were the primary and secondary outcomes, respectively, standardized using Hedges' g. Eligible articles underwent independent scrutiny by two authors, who also performed data extraction and quality assessment. Data pooling was accomplished using a random-effects model. RESULTS In total, five randomized controlled trials comprising 198 participants were included, revealing a trend effect toward disability improvement in the LSSE group (Hedges' g=-0.598, 95% CI=-1.211 to 0.016, P=0.056, I2=75.447%). When the LSSE was administered as a single treatment, disability improvement became significant (Hedges' g=-1.325, 95% CI=-2.598 to -0.053, P=0.041, I2=80.020%). No significant effect of LSSE on pain reduction was observed (Hedges' g=-0.496, 95% CI=-1.082 to 0.090, P=0.097, I2=73.935%). CONCLUSION In summary, our meta-analysis suggests that LSSE can potentially improve disability, especially when used as a single treatment. LSSE appears more beneficial in reducing disability than alleviating pain. Future research on different patient groups is needed to understand comprehensively LSSE's effects on other musculoskeletal disorders.

Abstract
Assessment of the posterior lateral knee pain poses diagnostic challenges, requiring accurate evaluation of various structures in light of the medical history and physical examination. Despite substantial progress in the ultrasonographic diagnosis of musculoskeletal disorders, the current protocol (EURO-MUSCULUS/USPRM. Basic scanning protocols for knee) fails to conduct a comprehensive investigation into the intricate, tendons, and ligaments of the posterior lateral knee. This pictorial review aims to bridge this gap by offering a systematic approach to utilize ultrasound examination of the less-discussed structures in this specific region. Providing cadaveric and magnetic resonance images, this essay demonstrates the efficacy of ultrasound in diagnosing posterior lateral knee pain. Notably, pathologies such as ligamentous sprains and tears are clearly discernible. Moreover, the integration of ultrasound guidance plays a vital role in reducing the risk of inadvertent neurovascular injury during injection, such as the common peroneal nerve and lateral genicular artery. This comprehensive approach will enhance clinicians' understanding and equip them with effective management strategies for posterior lateral knee pain.Critical relevance statement In this visual exposition, we delve into the intricacies of the posterior lateral corner of the knee. Offering a methodical approach to employ ultrasound for visualization of the less-explored structures within this region, the authors aim to enhance the diagnosis in posterior lateral knee pain.Key points1. Ultrasound excels at revealing intricate structures in the posterior lateral knee.2. Due to proximity of vital structures, extreme caution is crucial during injections.3. Employing dynamic scan and understanding ligaments enables a comprehensive exploration of pathologies.

Abstract
OBJECTIVE Injection of the tibiotalar (TT) joint is commonly performed in clinical practice under ultrasound (US) guidance using an anteromedial approach. However, in some patients, this approach may be technically challenging due to post-traumatic and/or degenerative bony changes. Therefore, the aim of this cadaveric investigation was to demonstrate the feasibility of the ultrasound-guided (USG) injection of the ankle joint via the anterolateral sulcus (ALS) by confirming the dye placement/distribution inside the articular space. Likewise, the safety of the procedure has also been evaluated by measuring the distance between the needle and the intermediate dorsal cutaneous nerve of the foot. DESIGN A descriptive laboratory study with eight embalmed cadaveric ankles using the Fix for Life (F4L) method was performed at the setting of an academic institution. The interventional technique and the related anatomical findings were illustrated. During the injection, the needle was advanced into the TT joint through the ALS under US guidance, i.e., in-plane anterior-to-posterior approach. With the objective to confirm its correct placement, the needle was kept in situ and-to demonstrate the location of the dye inside the articular space-all eight ankles were injected with 3 mL of green color dye. Thereafter, a layer-by-layer anatomical dissection was performed on all four cadavers. RESULTS The position of the needle's tip within the ALS was confirmed in all specimens. Accurate placement of the dye inside the articular space of the ankle was confirmed in seven of the eight cadaveric ankles, with 87.5% of accuracy. Herewith, unintentional spilling of the dye within the superficial soft tissues was reported in two of the eight ankles (25.0%). The mean distance between the needle and the intermediate dorsal cutaneous nerve of the foot, measured in all eight procedures, was 3 cm. CONCLUSION USG injection of the ALS using the in-plane, anterior-to-posterior approach can accurately place the injectate inside the articular space. CLINICAL RELEVANCE This cadaveric investigation described the accuracy and potential pitfalls of USG injection of the ankle via the anterolateral approach which represents an alternative technique in patients with reduced accessibility of the anteromedial recess due to degenerative and/or post-traumatic bony changes.

Abstract
BACKGROUND Chronic neck pain (CNP) is a common musculoskeletal disorder. Pain neuroscience education (PNE) is a promising nonpharmacological intervention for CNP, however, its effectiveness remains unclear. This systematic review and meta-analysis aimed to evaluate the effectiveness of PNE in treating CNP. METHODS Electronic databases from inception to February 2023 were searched for randomized controlled trials (RCTs) on the effects of PNE on CNP. The primary outcome was the change in pain intensity, and the secondary outcome was improvement in kinesiophobia, standardized using Hedges' g. Two authors independently scrutinized eligible articles, extracted data and assessed quality; a random-effects model was employed for data pooling. RESULTS In total, seven RCTs comprising 479 participants were included and demonstrated that PNE significantly reduced pain intensity (Hedges' g = -0.730, 95% CI = -1.340 to -0.119, p = 0.019, I2 = 89.288%). Subgroup analysis revealed that the adult group experienced significant pain reduction after PNE, whereas the adolescent group did not. PNE also reduced kinesiophobia which was evaluated in four of seven RCTs (Hedges' g = -0.444, 95% CI = -0.735 to -0.154, p = 0.003, I2 = 36.822%). The meta-regression analysis indicated that an increased intervention duration contributed to greater pain reduction. No adverse events were reported following PNE or the control treatment. CONCLUSIONS PNE effectively reduced pain intensity and kinesiophobia in patients with CNP. A longer PNE time leads to greater pain reduction and is more effective in adults than in adolescents. Further studies are required to examine the long-term effects on CNP management. SIGNIFICANCE This is the first meta-analysis evaluating the effectiveness of treating chronic neck pain with pain neuroscience education. Pain neuroscience education is successful in reducing pain and decreasing kinesiophobia in the chronic neck pain population. Longer treatment time leads to greater pain reduction.

Abstract
Agenesis and hypoplasia affecting multiple flexor tendons within the same hand represent an exceedingly uncommon occurrence, with no previous studies addressing this condition. This report details a 4-year-old girl with agenesis of the right third and fourth fingers, who sought consultation due to the inability to flex her seemingly unaffected second and fifth fingers. Ultrasound examination revealed substantial thinning of the flexor tendons in the second to fifth digits, with a notable absence of attachment to the middle phalanx. In addition to flexor tendon hypoplasia, hypoplasia of the third and fourth middle phalanges was observed. Hand deformities featuring both finger agenesis and flexor tendon hypoplasia across multiple fingers were exceptionally rare. In such instances, ultrasound, in conjunction with radiography, emerges as the recommended initial imaging tool for comprehensive evaluation of both the phalangeal bones and flexor tendons.

Abstract
Elucidating its dynamic interaction within the knee joint, this exploration delves into the awareness regarding the articularis genus muscle for ultrasound-guided suprapatellar recess injections. While injections into the infrapatellar recess may proceed without ultrasound guidance, we highlight concerns regarding the potential cartilage injury. In contrast, especially with ultrasound guidance, suprapatellar recess injections significantly mitigate this risk, especially in the case of collapsed recess. Originating from the distal femur and vastus intermedius, the articularis genus muscle influences the tension of the suprapatellar recess during knee motion. Sonographically identifying this muscle involves visualizing the slender linear structure of the suprapatellar recess, with guidance on differentiation from the vastus intermedius. We provide a succinct approach to ultrasound-guided suprapatellar recess injections, emphasizing needle insertion techniques and strategies to prevent fluid accumulation. In conclusion, this study serves as a concise clinician's guide, underscoring the significance of the articularis genus muscle's sonoanatomy in ultrasound-guided suprapatellar recess injections. Ultimately, procedural precision and patient safety can be advanced in this aspect.

Abstract
INTRODUCTION Superb microvascular imaging (SMI) is an advanced ultrasound technique that portrays microcirculation. Its clinical applications have been studied in various diseases, including carpal tunnel syndrome (CTS) i.e. the most common entrapment neuropathy. This scoping review explores the role of SMI in diagnosing CTS or the assessment of relevant neural structures. METHODS We conducted a comprehensive search of electronic databases (PubMed, Embase and Web of Science) up to 26 September 2023. Two independent authors conducted the literature search, quality assessment, and data extraction. RESULTS This review includes seven studies comprising 385 wrists. SMI consistently revealed increased intraneural vascularity in the median nerves of patients with CTS compared to healthy individuals. While SMI demonstrated higher sensitivity than traditional Doppler methods for detecting CTS, its specificity was somewhat lower. Combining SMI with B-mode ultrasound appears to enhance the diagnostic accuracy for CTS. However, the relationship between SMI findings and CTS severity remains unclear. CONCLUSIONS This review highlighted the ability of SMI to provide detailed vascular structures in both healthy wrists and those with CTS. Additional research is crucial to determine the typical SMI findings of the carpal tunnel and within that context, tailor more precise diagnostic/therapeutic applications for the CTS population.

From Histopathology to High-Resolution Ultrasound Imaging of Skin Scars. Diagnostics (Basel) 2023; 13:3629. [PMID: 38132213 PMCID: PMC10742690 DOI: 10.3390/diagnostics13243629] [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: 11/09/2023] [Revised: 12/02/2023] [Accepted: 12/04/2023] [Indexed: 12/23/2023] Open
Abstract
Nowadays, modern ultrasound machines and high-frequency transducers allow us to accurately assess the superficial soft tissues of the human body. In this sense, sonographic evaluation of the skin and related pathologies is progressively growing in the pertinent literature. To the best of our knowledge, a standardized sonographic protocol focused on the assessment of pathological skin scars is still lacking. As such, the main purpose of the present study was to propose a technical guide to sonographically assess skin scars in the daily practice of clinicians-starting from knowledge on their histopathological features. In order to standardize the ultrasound examination, a superficial-to-deep, layer-by-layer approach has been proposed to optimize its reproducibility and to promote a common language among the different healthcare providers.

Enhanced serum levels of tumor necrosis factor-α, interleukin-1β, and -6 in sarcopenia: alleviation through exercise and nutrition intervention. Aging (Albany NY) 2023; 15:13471-13485. [PMID: 38032288 DOI: 10.18632/aging.205254] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Accepted: 10/23/2023] [Indexed: 12/01/2023]
Abstract
BACKGROUND Limited research has been conducted on the post-intervention inflammatory status in sarcopenic patients, despite previous studies revealing elevated pro-inflammatory markers. This study aimed to investigate the potential elevation of specific pro-inflammatory cytokines in sarcopenic patients and evaluate the effects of exercise and nutritional support interventions on these cytokine levels. METHODS In this post-hoc analysis of a randomized controlled trial (RCT), 57 individuals with sarcopenia from the RCT and 57 non-sarcopenic participants from the same geriatric community cohort that did not participate in the RCT were enrolled. Grip strength and body composition measurements were recorded. Tumor necrotizing factor (TNF)-α, interleukin (IL)-1β, IL-6, and IL-15 levels were assessed at baseline for both groups and after a 12-week intervention consisting of resistive exercise and supplementation with branched-chain amino acids, calcium, and vitamin D3 in the patients with sarcopenia. RESULTS The sarcopenic group demonstrated significantly lower body weight, body mass index, grip strength, and skeletal muscle mass index. Moreover, sarcopenic patients exhibited higher levels of TNF-α (p=0.007), IL-1β (p<0.001), and IL-6 (p<0.001), while no significant difference was observed in IL-15 (p=0.345) between participants with and those without sarcopenia. Following the intervention, the sarcopenic group experienced significant improvements in grip strength and skeletal muscle mass index with a notable reduction in TNF-α (p=0.003), IL-1β (p=0.012) and IL-6 (p=0.001) levels. CONCLUSIONS Sarcopenic patients exhibit elevated levels of TNF-α, IL-1β, and IL-6, which declined after nutrition support and exercise interventions. However, further research is necessary to evaluate the long-term impact of these interventions on cytokine levels.

Neural Mobilization for Reducing Pain and Disability in Patients with Lumbar Radiculopathy: A Systematic Review and Meta-Analysis. Life (Basel) 2023; 13:2255. [PMID: 38137856 PMCID: PMC10744707 DOI: 10.3390/life13122255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 11/20/2023] [Accepted: 11/21/2023] [Indexed: 12/24/2023] Open
Abstract
Lumbar radiculopathy causes lower back and lower extremity pain that may be managed with neural mobilization (NM) techniques. This meta-analysis aims to evaluate the effectiveness of NM in alleviating pain and reducing disability in patients with lumbar radiculopathy. We hypothesized that NM would reduce pain and improve disability in the lumbar radiculopathy population, leveraging the statistical power of multiple studies. Electronic databases from their inception up to October 2023 were searched for randomized controlled trials (RCTs) that explored the impact of NM on lumbar radiculopathy. Our primary outcome measure was the alteration in pain intensity, while the secondary one was the improvement of disability, standardized using Hedges' g. To combine the data, we employed a random-effects model. A total of 20 RCTs comprising 877 participants were included. NM yielded a significant reduction in pain intensity (Hedges' g = -1.097, 95% CI = -1.482 to -0.712, p < 0.001, I2 = 85.338%). Subgroup analyses indicated that NM effectively reduced pain, whether employed alone or in conjunction with other treatments. Furthermore, NM significantly alleviated disability, with a notable effect size (Hedges' g = -0.964, 95% CI = -1.475 to -0.453, p < 0.001, I2 = 88.550%), particularly in chronic cases. The findings provide valuable insights for clinicians seeking evidence-based interventions for this patient population. This study has limitations, including heterogeneity, potential publication bias, varied causal factors in lumbar radiculopathy, overall study quality, and the inability to explore the impact of neural pathology on NM treatment effectiveness, suggesting opportunities for future research improvements.

High-resolution ultrasound imaging of elementary lesions in dactylitis. J Ultrasound 2023:10.1007/s40477-023-00834-z. [PMID: 38006512 DOI: 10.1007/s40477-023-00834-z] [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: 07/22/2023] [Accepted: 10/02/2023] [Indexed: 11/27/2023] Open
Abstract
OBJECTIVE The aim of the present study was to illustrate the (potential) diagnostic role of high resolution US images in assessing the elementary lesions of dactylitis. METHODS Using high-frequency US machines/probes, we matched the micro-anatomical cadaveric architecture of the digit with multiple sonographic findings of dactylitis. High-sensitive color/power Doppler assessments have also been performed to evaluate the digital microvasculature. DISCUSSION Modern US equipment/features guarantee prompt and in-depth B-mode and color/power Doppler imaging of tiny anatomical structures of the digit which are usually not properly visible with standard US machines. More specifically, hypervascularization of the digital subcutaneous tissue, fibrous pulleys of flexor tendons, dorsal synovial pads as well as pathological changes of the distal entheseal anchorage network can be accurately detected. CONCLUSION In clinical practice, high-end US equipment can be used to accurately assess the digits in patients with dactylitis. This way, simple and convenient sonographic diagnosis of different elementary lesions can be timely established.

Abstract
BACKGROUND Ultrasound (US) guided intra-articular elbow injections are commonly performed in clinical practice. OBJECTIVE To describe a proximal to distal approach for US-guided intra-articular elbow injection. DESIGN Cadaveric study. SETTINGS Academic institution. METHODS Both elbows of a single cadaver were injected with green-colored water-diluted latex dye using the US-guided proximal to distal approach. In the left elbow, the needle was kept in situ; in the right elbow, the needle was removed. Subsequently, a layer-by-layer anatomical dissection was performed in both elbows. MAIN OUTCOME MEASURES Presence and distribution of the latex dye and location of the needle tip within the elbow joint capsule. RESULTS Anatomical dissection of both elbows confirmed the correct intra-articular position of the needle tip in the left elbow as well as correct placement of the latex dye bilaterally. During layer-by-layer dissection of the left elbow, the position of the radial nerve was observed anterior to the needle. CONCLUSIONS This cadaveric observation demonstrated that the US-guided proximal to distal approach is a convenient technique to access the elbow joint. Compared to the previously described techniques, the in-plane, proximal to distal approach may provide excellent needle visibility during the entire procedure, precisely targeting the articular space. The preliminary data need to be validated in additional clinical studies.

Abstract
Background To investigate the effectiveness of muscle energy technique (MET) for treatment of non-specific neck pain (NSNP). Methods A literature search was performed using electronic databases from their inception until October 2023 for randomized controlled trials (RCTs) that investigated the effects of MET on NSNP. A change in pain intensity and reduced disability were the primary and secondary outcomes, respectively, standardized using Hedges' g. A random effects model was used for data pooling. Results This study included 26 RCTs comprising 1170 participants. The results showed that MET significantly reduced pain intensity (Hedges' g = -0.967 95 % CI = -1.417 to -0.517, p < 0.001). However, subgroup analysis revealed that this significant benefit was observed only when MET was combined with other treatments and not with MET monotherapy. MET also reduced disability (Hedges' g = -0.545, 95 % CI = -1.015 to - 0.076, p = 0.023). Meta-regression analysis showed that an increase in treatment duration/session per week contributed to greater pain reduction. No adverse events were reported following the MET. Conclusions In conclusion, our meta-analysis suggests MET's potential effectiveness within a combined treatment for NSNP. However, the evidence's low certainty is likely influenced by bias and study variations. To strengthen these findings, future research should focus on higher-quality clinical trials, longer follow-up periods, and prediction interval presentations.

Abstract
Background: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy for which ultrasound imaging has recently emerged as a valuable diagnostic tool. This meta-analysis aims to investigate the role of ultrasound radiomics in the diagnosis of CTS and compare it with other diagnostic approaches. Methods: We conducted a comprehensive search of electronic databases from inception to September 2023. The included studies were assessed for quality using the Quality Assessment Tool for Diagnostic Accuracy Studies. The primary outcome was the diagnostic performance of ultrasound radiomics compared to radiologist evaluation for diagnosing CTS. Results: Our meta-analysis included five observational studies comprising 840 participants. In the context of radiologist evaluation, the combined statistics for sensitivity, specificity, and diagnostic odds ratio were 0.78 (95% confidence interval (CI), 0.71 to 0.83), 0.72 (95% CI, 0.59 to 0.81), and 9 (95% CI, 5 to 15), respectively. In contrast, the ultrasound radiomics training mode yielded a combined sensitivity of 0.88 (95% CI, 0.85 to 0.91), a specificity of 0.88 (95% CI, 0.84 to 0.92), and a diagnostic odds ratio of 58 (95% CI, 38 to 87). Similarly, the ultrasound radiomics testing mode demonstrated an aggregated sensitivity of 0.85 (95% CI, 0.78 to 0.89), a specificity of 0.80 (95% CI, 0.73 to 0.85), and a diagnostic odds ratio of 22 (95% CI, 12 to 41). Conclusions: In contrast to assessments by radiologists, ultrasound radiomics exhibited superior diagnostic performance in detecting CTS. Furthermore, there was minimal variability in the diagnostic accuracy between the training and testing sets of ultrasound radiomics, highlighting its potential as a robust diagnostic tool in CTS.

Assessing thickness and stiffness of superficial/deep masticatory muscles in orofacial pain: an ultrasound and shear wave elastography study. Ann Med 2023; 55:2261116. [PMID: 37791609 PMCID: PMC10552583 DOI: 10.1080/07853890.2023.2261116] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Accepted: 09/17/2023] [Indexed: 10/05/2023] Open
Abstract
INTRODUCTION Sonoelastography has been increasingly used for non-invasive evaluation of the mechanical features of human tissues. The interplay between orofacial pain and regional muscle activity appears clinically paramount, although only few imaging studies have investigated this association. Using shear wave sonoelastography (SWS), this study ascertained whether orofacial pain induced alterations in the stiffness of superficial and deep masticatory muscles. METHODS All participants were systematically evaluated for oral/facial-related conditions, including the area and intensity of pain. SWS was applied to measure the stiffness of the bilateral masseter, temporalis, and lateral pterygoid muscles. The association between orofacial pain and muscle stiffness/thickness was investigated using a generalized estimating equation for adjusting the influence of age, sex, laterality, and body mass index on muscle thickness/stiffness. RESULTS A total of 98 participants were included in the present study: 48 asymptomatic controls, 13 patients with unilateral pain, and 37 patients with bilateral orofacial pain. The reliability, quantified by the intraclass correlation coefficient for muscle stiffness measurement, ranged from 0.745 to 0.893. Orofacial pain at the individual muscle level was significantly associated with masseter muscle stiffness. A trend of increased stiffness (p = 0.06) was also observed in relation to the painful side of the temporalis muscle. No significant correlation was identified between the numeric rating scales for pain and stiffness measurements. CONCLUSIONS SWS provides reliable stiffness measurements for the superficial and deep masticatory muscles. The ipsilateral masseter and temporalis muscles might be stiffer than those on the side without orofacial pain. Future studies using the present sonoelasotography protocol can be designed to investigate the stiffness changes in the target muscles after interventions.

Abstract
BACKGROUND Ultrasound imaging has emerged as one of the most useful tools for evaluating shoulder disorders. To date, the association between shoulder ultrasonography and a patient's work status has rarely been explored by antecedent studies. AIM This study aimed to investigate the association between sonographically diagnosed shoulder pathologies and job discontinuation and return to work. DESIGN A cross-sectional study. SETTING Outpatient clinic in the university hospital. POPULATION Fifty-nine patients who were older than 20 years of age and had worked in a full-time job within the past three years. METHODS All participants underwent clinical evaluation using the visual analog scale (for pain), Shoulder Pain and Disability Index, Pittsburgh Sleep Quality Index, and shoulder ultrasound examination. The work-related ergonomic risks, including dealing with heavy objects, repeated use and requiring forceful motion of the affected upper extremity, were assessed. The ultrasound-identified shoulder pathologies associated with job discontinuation, that is, sick leave due to painful shoulder for more than two consecutive months, were considered as the primary outcome. In the job discontinuation subgroup, we further investigated the association between return to work and the clinical/sonographic findings. RESULTS Univariate analysis revealed a positive association between job discontinuation and shoulder surgery or work types requiring forceful upper-limb movements. Multivariate analysis demonstrated that job discontinuation was positively associated with supraspinatus tendon full-thickness tears (risk ratio, 8.80; 95% CI, 1.77-10.56; P=0.018). Of the patients who received shoulder surgery, 46.6% had recurrent rotator cuff tears. Return to work was likely to be related to pain scores during overhead activities and shoulder function impairment but not to sonographic findings. CONCLUSIONS Job discontinuation is associated with shoulder surgery, work that necessitates forceful upper-extremity movements and supraspinatus tendon full-thickness tears detected by ultrasound. CLINICAL REHABILITATION IMPACT Sonographic findings should not be used as the only standard for evaluating the patient's work capability.

Abstract
BACKGROUND Ultrasound (US)-guided intraarticular hip joint injections are commonly performed using an in-plane anterior approach, which has several limitations. OBJECTIVE To describe and report a "lateral" (lateral to medial) approach for US-guided intraarticular hip injection. DESIGN Cadaveric investigation. SETTING Academic institution, department of anatomy. PARTICIPANTS One cadaveric specimen. METHODS Both hips of a single cadaver were injected using the US-guided lateral approach. In the left hip, the needle was inserted and kept in situ. The right hip was injected with white-colored water-diluted latex dye. Subsequently, a layer-by-layer anatomical dissection was performed. MAIN OUTCOME MEASURES Presence and distribution of latex dye and location of needle tip within the joint capsule of the hip. RESULTS Anatomical dissection of the left and right hips confirmed the correct intraarticular position of the needle tip and the placement of the latex dye, respectively. During layer-by-layer dissection of the left hip, positions of the lateral cutaneous nerve and the lateral circumflex femoral artery were observed anterior to the needle, 30 mm for the nerve and 8 mm for the artery. CONCLUSIONS This preliminary study demonstrated that the US-guided lateral approach is a convenient technique to access the hip joint in a cadaveric specimen. Compared with the "classical" anterior technique, the lateral approach may provide several advantages, including improved needle visibility, theoretically decreased risk of vascular injury, and less risk of needle contamination. Because injury to the lateral epiphyseal arteries is possible when lateral approach is used, caution is required, especially in children. These preliminary conclusions will need to be validated in future/larger clinical studies.

Abstract
OBJECTIVE Post-stroke shoulder pain is a serious challenge for stroke survivors. The aim of this meta-analysis was to review the literature to confirm information on structural changes in post-stroke shoulders detected by ultrasound examination. METHODS PubMed, Embase, Web of Science and ClinicalTrials.gov were searched until 7 December 2022, for studies describing shoulder sonographic findings in stroke patients. Two independent authors selected the studies, extracted the data, and performed the critical appraisal. RESULTS A total of 23 clinical studies were included. The most prevalent pathologies in hemiplegic shoulders pertained to the biceps long head tendon (41.4%), followed by the supraspinatus tendon (33.2%), subdeltoid bursa (29.3%), acromioclavicular joint (15.0%), and subscapularis tendon (9.2%). The common pathological findings encompassed bicipital peritendinous effusion (39.2%), biceps tendinopathy (35.5%), subdeltoid bursitis (29.3%) and supraspinatus tendinopathy (24.6%). Biceps long head tendon and supraspinatus tendon abnormalities were observed significantly more in the hemiplegic (vs contralateral) shoulders, with odds ratios of 3.814 (95% confidence interval 2.044-7.117) and 2.101 (95% confidence interval 1.257-3.512), respectively. No correlation was observed between motor function and shoulder pathology. CONCLUSION Ultrasonography enabled the identification of common shoulder pathologies after stroke. Further research is needed to establish the association between these changes and the clinical course of stroke patients.

Involvement of ASIC3 and Substance P in Therapeutic Ultrasound-Mediated Analgesia in Mouse Models of Fibromyalgia. THE JOURNAL OF PAIN 2023; 24:1493-1505.

Abstract
Therapeutic ultrasound (tUS) is widely used in chronic muscle pain control. However, its analgesic molecular mechanism is still not known. Our objective is to reveal the mechanism of the tUS-induced analgesia in mouse models of fibromyalgia. We applied tUS in mice that have developed chronic hyperalgesia induced by intramuscular acidification and determined the tUS frequency at 3 MHz, dosage at 1 W/cm2 (measured output as 6.3 mW/cm2) and 100% duty cycle for 3 minutes having the best analgesic effect. Pharmacological and genetic approaches were used to probe the molecular determinants involved in tUS-mediated analgesia. A second mouse model of fibromyalgia induced by intermittent cold stress was further used to validate the mechanism underlying the tUS-mediated analgesia. The tUS-mediated analgesia was abolished by a pretreatment of NK1 receptor antagonist-RP-67580 or knockout of substance P (Tac1-/-). Besides, the tUS-mediated analgesia was abolished by ASIC3-selective antagonist APETx2 but not TRPV1-selective antagonist capsazepine, suggesting a role for ASIC3. Moreover, the tUS-mediated analgesia was attenuated by ASIC3-selective nonsteroid anti-inflammation drugs (NSAIDs)-aspirin and diclofenac but not by ASIC1a-selective ibuprofen. We next validated the antinociceptive role of substance P signaling in the model induced by intermittent cold stress, in which tUS-mediated analgesia was abolished in mice lacking substance P, NK1R, Asic1a, Asic2b, or Asic3 gene. tUS treatment could activate ASIC3-containing channels in muscle afferents to release substance P intramuscularly and exert an analgesic effect in mouse models of fibromyalgia. NSAIDs should be cautiously used or avoided in the tUS treatment. PERSPECTIVE: Therapeutic ultrasound showed analgesic effects against chronic mechanical hyperalgesia in the mouse model of fibromyalgia through the signaling pathways involving substance P and ASIC3-containing ion channels in muscle afferents. NSAIDs should be cautiously used during tUS treatment.

Abstract
OBJECTIVES Low back pain is a prevalent public health issue caused by superior cluneal nerve (SCN) entrapment. This study aimed to explore the course of SCN branches, cross-sectional area (CSA) of the nerves, and effects of ultrasound-guided SCN hydrodissection. METHODS SCN distance relative to the posterior superior iliac spines was measured and compared with ultrasound findings in asymptomatic volunteers. The CSA of the SCN, pressure-pain threshold, and pain measurements were obtained from asymptomatic controls and patients with SCN entrapment at various time points after hydrodissection (with 1 mL of 50% dextrose, 4 mL of 1% lidocaine, and 5 mL of 1% normal saline) in the short-axis view. RESULTS Twenty sides of 10 formalin-fixed cadavers were dissected. The SCN locations on the iliac crest did not differ from the ultrasound findings in 30 asymptomatic volunteers. The average CSA of the SCN across different branches and sites ranged between 4.69-5.67 mm2 and did not vary across different segments/branches or pain statuses. Initial treatment success was observed in 77.7% (n = 28) of 36 patients receiving hydrodissection due to SCN entrapment. A group with initial treatment success experienced symptom recurrence in 25% (n = 7) of cases, and those with recurrent pain had a higher prevalence of scoliosis than those without symptom recurrence. CONCLUSIONS Ultrasonography effectively localizes SCN branches on the iliac crest, whereby increased nerve CSA is not useful for diagnosis. Most patients benefit from ultrasound-guided dextrose hydrodissection; however, those with scoliosis may experience symptom recurrence and whether structured rehabilitation can reduce recurrence post-injection should be considered as one perspective in future research. Trial registration ClinicalTrials.gov (NCT04478344). Registered on 20 July 2020, https://clinicaltrials.gov/ct2/show/NCT04478344?cond=Superior+Cluneal+Nerve&cntry=TW&draw=2&rank=1 . Critical relevance statement Ultrasound imaging accurately locates SCN branches on the iliac crest, while enlargement of the CSA is not useful in diagnosing SCN entrapment; however, approximately 80% of SCN entrapment cases respond positively to ultrasound-guided dextrose hydrodissection.

Abstract
Ultrasound has emerged as a highly valuable tool in imaging peripheral nerve lesions in the wrist region, particularly for common pathologies such as carpal tunnel and Guyon's canal syndromes. Extensive research has demonstrated nerve swelling proximal to the entrapment site, an unclear border, and flattening as features of nerve entrapments. However, there is a dearth of information regarding small or terminal nerves in the wrist and hand. This article aims to bridge this knowledge gap by providing a comprehensive overview concerning scanning techniques, pathology, and guided-injection methods for those nerve entrapments. The median nerve (main trunk, palmar cutaneous branch, and recurrent motor branch), ulnar nerve (main trunk, superficial branch, deep branch, palmar ulnar cutaneous branch, and dorsal ulnar cutaneous branch), superficial radial nerve, posterior interosseous nerve, palmar common/proper digital nerves, and dorsal common/proper digital nerves are elaborated in this review. A series of ultrasound images are used to illustrate these techniques in detail. Finally, sonographic findings complement electrodiagnostic studies, providing better insight into understanding the whole clinical scenario, while ultrasound-guided interventions are safe and effective for treating relevant nerve pathologies.

Deep learning algorithm for predicting subacromial motion trajectory: Dynamic shoulder ultrasound analysis. ULTRASONICS 2023; 134:107057. [PMID: 37290256 DOI: 10.1016/j.ultras.2023.107057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 05/14/2023] [Accepted: 05/24/2023] [Indexed: 06/10/2023]
Abstract
Subacromial motion metrics can be extracted from dynamic shoulder ultrasonography, which is useful for identifying abnormal motion patterns in painful shoulders. However, frame-by-frame manual labeling of anatomical landmarks in ultrasound images is time consuming. The present study aims to investigate the feasibility of a deep learning algorithm for extracting subacromial motion metrics from dynamic ultrasonography. Dynamic ultrasound imaging was retrieved by asking 17 participants to perform cyclic shoulder abduction and adduction along the scapular plane, whereby the trajectory of the humeral greater tubercle (in relation to the lateral acromion) was depicted by the deep learning algorithm. Extraction of the subacromial motion metrics was conducted using a convolutional neural network (CNN) or a self-transfer learning-based (STL)-CNN with or without an autoencoder (AE). The mean absolute error (MAE) compared with the manually-labeled data (ground truth) served as the main outcome variable. Using eight-fold cross-validation, the average MAE was proven to be significantly higher in the group using CNN than in those using STL-CNN or STL-CNN+AE for the relative difference between the greater tubercle and lateral acromion on the horizontal axis. The MAE for the localization of the two aforementioned landmarks on the vertical axis also seemed to be enlarged in those using CNN compared with those using STL-CNN. In the testing dataset, the errors in relation to the ground truth for the minimal vertical acromiohumeral distance were 0.081-0.333 cm using CNN, compared with 0.002-0.007 cm using STL-CNN. We successfully demonstrated the feasibility of a deep learning algorithm for automatic detection of the greater tubercle and lateral acromion during dynamic shoulder ultrasonography. Our framework also demonstrated the capability of capturing the minimal vertical acromiohumeral distance, which is the most important indicator of subacromial motion metrics in daily clinical practice.

Abstract
OBJECTIVE The aim of the study is to define a standardized comprehensive sonographic approach for evaluating the different histoanatomical compartments of the lateral elbow. DESIGN Using high-frequency ultrasound probes, we tried to match the anatomical features of the lateral elbow and its different sonographic patterns in patients with the diagnosis of lateral epicondylitis. Moreover, high-sensitive color/power Doppler assessments have also been performed to evaluate the microcirculation. RESULTS Modern ultrasound equipment seems to provide an extremely detailed sonographic assessment of the different anatomical layers located in the lateral compartment of the elbow. Moreover, high-sensitive color/power Doppler imaging allows for clear visualization of the perfusion patterns in pathological conditions. CONCLUSIONS In clinical practice, high-frequency B-mode and high-sensitive color/power Doppler imaging can be integrated with the clinical findings to better define the pain generator(s) for optimizing the management of patients with lateral epicondylitis.

Preoperative lung ultrasound for confirming the double-lumen endotracheal tube position for one-lung ventilation: A systematic review and meta-analysis. Heliyon 2023; 9:e15458. [PMID: 37128322 PMCID: PMC10147981 DOI: 10.1016/j.heliyon.2023.e15458] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 04/03/2023] [Accepted: 04/10/2023] [Indexed: 05/03/2023] Open
Abstract
Objectives Insertion of a double-lumen endotracheal tube (DLT) is the most commonly used method for one-lung ventilation (OLV). This meta-analysis was aimed at investigating the performance of lung ultrasound in assessing the DLT position in OLV. Methods Electronic databases were searched for related trials from inception to October 2022. The primary outcome was the performance of ultrasound or clinical evaluation in confirming the correctness of the DLT position, using fiberoptic bronchoscopy or intraoperative direct visualization of lung collapse as the gold standard. The secondary outcome was the time required to confirm or adjust the DTL position. Results Five randomized controlled trials and three observational studies involving 771 patients were included in the meta-analysis. The pooled sensitivity and specificity of ultrasound were 0.93 (95% confidence interval [CI]: 0.79-0.98) and 0.61 (95% CI: 0.41-0.77), respectively, while those of clinical evaluation were 0.93 (95% CI: 0.73-0.99) and 0.35 (95% CI: 0.25-0.47), respectively. The pooled procedure duration was 122.27 s (95% CI: 20.85-223.69) with ultrasound and 112.03 s (95% CI: 95.30-128.76) with clinical evaluation. The area under the curve for discriminating the DLT position was 0.86 (95% CI: 0.82-0.88) for ultrasound and 0.52 (95% CI: 0.48-0.57) for clinical evaluation. Conclusions Compared to clinical evaluation, ultrasound has a similar sensitivity but a better specificity for confirming the correctness of the DLT position. Ultrasound is an acceptable imaging tool for assessing DTL placement in OLV.

Abstract
OBJECTIVE High-resolution ultrasound is an emerging tool for diagnosing carpal tunnel syndrome caused by the compression of the median nerve at the wrist. This systematic review and meta-analysis aimed to explore and summarize the performance of deep learning algorithms in the automatic sonographic assessment of the median nerve at the carpal tunnel level. METHODS PubMed, Medline, Embase, and Web of Science were searched from the earliest records to May 2022 for studies investigating the utility of deep neural networks in the evaluation of the median nerve in carpal tunnel syndrome. The quality of the included studies was evaluated using the Quality Assessment Tool for Diagnostic Accuracy Studies. The outcome variables included precision, recall, accuracy, F-score, and Dice coefficient. RESULTS In total, seven articles were included, comprising 373 participants. The deep learning and related algorithms comprised U-Net, phase-based probabilistic active contour, MaskTrack, ConvLSTM, DeepNerve, DeepSL, ResNet, Feature Pyramid Network, DeepLab, Mask R-CNN, region proposal network, and ROI Align. The pooled values of precision and recall were 0.917 (95 % confidence interval [CI], 0.873-0.961) and 0.940 (95 % CI, 0.892-0.988), respectively. The pooled accuracy and Dice coefficient were 0.924 (95 % CI, 0.840-1.008) and 0.898 (95 % CI, 0.872-0.923), respectively, whereas the summarized F-score was 0.904 (95 % CI, 0.871-0.937). CONCLUSION The deep learning algorithm enables automated localization and segmentation of the median nerve at the carpal tunnel level in ultrasound imaging with acceptable accuracy and precision. Future research is expected to validate the performance of deep learning algorithms in detecting and segmenting the median nerve along its entire length as well as across datasets obtained from various ultrasound manufacturers.

Abstract
Cervical myofascial pain is a very common clinical condition in the daily practice of musculoskeletal physicians. Physical examination is currently the cornerstone for evaluating the cervical muscles and identifying the eventual presence of myofascial trigger points. Herein, the role of ultrasound assessment in precisely localizing them is progressively mounting in the pertinent literature. Moreover, using ultrasound, not only the muscle tissue but also the fascial and neural elements can be accurately located/evaluated. Indeed, several potential pain generators, in addition to paraspinal muscles, can be involved in the clinical scenario of cervical myofascial pain syndrome. In this article, the authors extensively reviewed the sonographic approach for cervical myofascial pain in order to better diagnose or guide different procedures that can be performed in the clinical practice of musculoskeletal physicians.

Abstract
Lateral epicondylitis (LE) is a very common and painful condition seen in the daily practice of musculoskeletal physicians. Ultrasound-guided (USG) injections are commonly performed to manage the pain, promote the healing phase, and plan a tailored rehabilitation treatment. In this aspect, several techniques were described to target specific pain generators i the lateral elbow. Likewise, the aim of this manuscript was to extensively review those USG techniques together with the patients' pertinent clinical/sonographic features. The authors believe that this literature summary could also be refined as a practical, ready-to-use guide for planning the USG interventions of the lateral elbow in clinical practice.
