Aim: To investigate whether linear measurements or ratios on the Graf's "standard plane" ultrasound images of the neonatal/infantile hip, can support the clinically important differentiation between type I and type II hips.

Material and methods: A total of 60 Graf type II hips and 124 randomly selected Graf type I hips, matched to the gestational age at delivery, birth weight, delivery mode, and age at the time of the examination, were identified through our hip screening service, during a period of two years. The images were diagnostically suitable, following anatomical identification and usability check, according to Graf. Anatomical landmarks including the lower limb of the os ilium, the bony rim, the silhouette of the os ilium, the labrum and the femoral head's borders, were used to determine the measurements and ratios which quantified their inter-relationships.

Results: The indices which differed significantly between type I and type II hips included: (a) the width of the "bony roof" (cut-off value 5.91 mm, sensitivity: 75%, specificity: 70%), (b) the ratio of the width of the "bony roof" to the femoral head's width (cut-off value 0.40, sensitivity 83%, specificity 71%), and (c) the ratio of the cartilaginous acetabular roof's width (including the labrum), to the width of the femoral head (cut-off value 0.450, sensitivity 82%, specificity 67%).

Conclusions: Newly introduced measurements and calculated ratios on "standard plane" ultrasound images can be used as additional indices in the differentiation between Graf's types of "centered hips", thus increasing the diagnostic certainty of the examiner in borderline cases and limiting unnecessary re-examinations or treatment.

目的:研究新生儿/婴儿髋关节格拉夫 "标准平面 "超声图像上的线性测量值或比率是否有助于临床上区分I型和II型髋关节:在两年的时间里,我们通过髋关节筛查服务共发现了 60 个格拉夫 II 型髋关节和 124 个随机抽取的格拉夫 I 型髋关节,它们与分娩时的胎龄、出生体重、分娩方式和检查时的年龄相匹配。根据格拉夫的说法,经过解剖鉴定和可用性检查,这些图像在诊断上是合适的。解剖地标包括髂骨下缘、骨缘、髂骨轮廓、髂唇和股骨头边界,这些地标被用来确定测量值和比率,量化它们之间的相互关系:结果:Ⅰ型和Ⅱ型髋关节之间存在明显差异的指标包括(a) "骨顶 "宽度(临界值为 5.91 毫米,敏感性:75%,特异性:70%),(b) "骨顶 "宽度与股骨头宽度的比率(临界值为 0.40,灵敏度为 83%,特异度为 71%),以及 (c) 髋臼软骨顶宽度(包括髋臼唇)与股骨头宽度之比(临界值为 0.450,灵敏度为 82%,特异度为 67%):结论:在 "标准平面 "超声图像上新引入的测量值和计算比率可作为区分格拉夫 "中心髋 "类型的附加指标,从而提高检查者对边缘病例的诊断确定性,并限制不必要的复查或治疗。

Radiography is the appropriate initial imaging modality to assess for midfoot and forefoot pathology before turning to advanced imaging techniques. While most lesions of the mid- and forefoot can be diagnosed clinically, the exact nature and severity of the pathology is often unclear. This review addresses the use of the ultrasound, as well as the added value of magnetic resonance imaging, in diagnosing conditions of the mid- foot and forefoot. Ultrasound allows a dynamic assessment as well as enabling imaging-guided interven- tions for diagnostic and therapeutic purposes. Practical tips for optimal examination of this area with ultra- sound and magnetic resonance imaging are provided. Metatarsal stress fracture, Chopart’s injury, Lisfranc injury, as well as the 1st metatarsophalangeal joint injury and lesser metatarsophalangeal plantar plate injury are injuries unique to the mid- and forefoot. The imaging anatomy of the 1st and lesser metatarsophalan- geal joints is reviewed, as such knowledge is key to correctly assessing injury of these joints. Characteristic imaging features of masses commonly encountered in the mid- and forefoot, such as ganglion cyst, Morton neuroma, gouty tophus, plantar fibroma, foreign body granuloma, and leiomyoma are reviewed. The use of ultrasound and magnetic resonance imaging in assessing degenerative and inflammatory joint disorders, and in particular rheumatoid arthritis, of the mid- and forefoot region is also reviewed. In summary, when necessary, most lesions of the mid-and forefoot can be adequately assessed with ultrasound, supplemented on occasion with radiographs, computed tomography, or magnetic resonance imaging.
在采用先进的影像学技术之前,影像学是评估足中部和前足病理的合适的初始成像方式。虽然大多数中前脚病变可以在临床上诊断,但病理的确切性质和严重程度往往不清楚。这篇综述论述了超声的使用,以及磁共振成像的附加价值,在诊断中足和前足的条件。超声允许动态评估,以及使成像引导干预诊断和治疗的目的。本文提供了超声和磁共振成像对该区域进行最佳检查的实用技巧。跖骨应力性骨折、Chopart损伤、Lisfranc损伤以及第一跖趾关节损伤和小跖趾趾跖板损伤是中、前足特有的损伤。本文回顾了第一及第二跖骨关节的影像学解剖,因为这些知识是正确评估这些关节损伤的关键。本文综述了神经节囊肿、莫顿神经瘤、痛风结节、足底纤维瘤、异物肉芽肿、平滑肌瘤等中前足常见肿块的影像学特征。超声和磁共振成像在评估退行性和炎症性关节疾病,特别是类风湿性关节炎,中、前足区域的使用也进行了审查。总之,必要时,大多数中前脚病变可以用超声充分评估,偶尔辅以x线片、计算机断层扫描或磁共振成像。

This paper reviews ultrasound of the hip, which is a commonly requested examination for symptomatic hip issues. This includes both intra-articular and extra-articular causes of hip pain. Ultrasound is easily acces- sible, lacks radiation exposure, and allows for evaluation of the contralateral hip as well as assessment of dy- namic maneuvers. Ultrasound can be used to guide interventional procedures. Ultrasound of the hip can be challenging due to the deep location of structures and complex anatomy. Typically, high-frequency trans- ducers are used to examine the hip, however the choice of ultrasound transducer depends on the patient’s body habitus, with lower frequency transducers required to penetrate deep structures in obese patients. It is important to have an approach to ultrasound of the hip which includes assessment of the anterior, lateral, posterior, and medial aspects of the hip. The technique and relevant anatomy of each of these compart- ments are discussed as well as the use of Doppler examination of the hip. Several dynamic maneuvers can be performed to help determine the cause of hip pathology in various locations, and these are described and illustrated. Ultrasound is useful for guided procedures about the hip, and these indications will be reviewed.
本文回顾了髋关节超声检查,这是一种常见的检查要求的症状性髋关节问题。这包括髋关节疼痛的关节内和关节外原因。超声很容易获得,缺乏辐射暴露,并允许评估对侧髋关节以及动态机动的评估。超声可用于指导介入手术。髋关节的超声检查由于其深层结构和复杂的解剖结构而具有挑战性。通常,高频换能器用于检查髋关节,然而超声换能器的选择取决于患者的身体习惯,肥胖患者需要低频换能器来穿透深层结构。髋关节超声检查包括髋关节的前部、外侧、后部和内侧的评估,这一点很重要。本文讨论了这些部位的技术和相关解剖,以及髋部多普勒检查的使用。几个动态操作可以执行,以帮助确定在不同位置的髋关节病理的原因,这些描述和说明。超声对髋关节的引导手术是有用的,这些适应症将被回顾。

Lower extremity peripheral neuropathy is a commonly encountered neurologic disorder, which can lead to chronic pain, functional disability, and decreased quality of life for a patient. As diagnostic imaging modalities have improved, imaging has started to play an integral role in the detection and characterization of peripheral nerve abnormalities by non-invasively and accurately identifying abnormal nerves as well as potential causes of neuropathy, which ultimately leads to precise and timely treatment. Ultrasound, which has high spatial resolution and can quickly and comfortably characterize peripheral nerves in real time along with associated denervation muscle atrophy, and magnetic resonance neurography, which provides excellent contrast resolution between nerves and other tissues and between pathologic and normal seg- ments of peripheral nerves, in addition to assessing reversible and irreversible muscle denervation changes, are the two mainstay imaging modalities used in peripheral nerve assessment. These two modalities are complimentary, and one may be more useful than the other depending on the nerve and location of pathol- ogy. Imaging must be interpreted in the context of available clinical information and other diagnostic stud- ies, such as electrodiagnostic tests. Here, we offer a comprehensive overview of the role of high-resolution ultrasound and magnetic resonance neurography in the evaluation of the peripheral nerves of the lower extremity and their associated neuropathies.
下肢周围神经病变是一种常见的神经系统疾病,可导致慢性疼痛、功能障碍和患者生活质量下降。随着影像学诊断方式的不断完善,影像学已开始在周围神经异常的检测和表征中发挥不可或缺的作用,通过无创、准确地识别异常神经以及神经病变的潜在原因,最终实现精确、及时的治疗。超声具有高空间分辨率,可以快速舒适地实时表征周围神经以及相关的去神经支配肌肉萎缩;磁共振神经成像除了评估可逆和不可逆的肌肉去神经支配变化外,还可以提供神经与其他组织以及周围神经病理和正常段之间的出色对比分辨率。是周围神经评估中使用的两种主要成像方式。这两种方式是互补的,一种可能比另一种更有用,这取决于神经和病理位置。影像学必须在现有临床信息和其他诊断研究(如电诊断试验)的背景下进行解释。在这里,我们提供了一个全面的概述高分辨率超声和磁共振神经成像在评估下肢周围神经及其相关神经病变中的作用。

During the past four decades, musculoskeletal ultrasound has become popular as an imaging modality due to its low cost, accessibility, and lack of ionizing radiation. The development of ultrasound technology was possible in large part due to concomitant advances in both solid-state electronics and signal processing. The invention of the transistor and digital computer in the late 1940s was integral in its development. Moore’s prediction that the number of microprocessors on a chip would grow exponentially, resulting in progressive miniaturization in chip design and therefore increased computational power, added to these capabilities. The development of musculoskeletal ultrasound has paralleled technical advances in diagnostic ultrasound. The appearance of a large variety of transducer capabilities and rapid image processing along with the abil- ity to assess vascularity and tissue properties has expanded and continues to expand the role of musculo- skeletal ultrasound. It should also be noted that these developments have in large part been due to a number of individuals who had the insight to see the potential applications of this developing technology to a host of relevant clinical musculoskeletal problems. Exquisite high-resolution images of both deep and small super- ficial musculoskeletal anatomy, assessment of vascularity on a capillary level and tissue mechanical proper- ties can be obtained. Ultrasound has also been recognized as the method of choice to perform a large variety of interventional procedures. A brief review of these technical developments, the timeline over which these improvements occurred, and the impact on musculoskeletal ultrasound is presented below.
在过去的四十年中,肌肉骨骼超声由于其低成本,可及性和缺乏电离辐射而成为一种流行的成像方式。超声波技术的发展在很大程度上是由于固态电子学和信号处理的进步。20世纪40年代末晶体管和数字计算机的发明是其发展的重要组成部分。摩尔预测,芯片上的微处理器数量将呈指数级增长,从而导致芯片设计的逐步小型化,从而提高计算能力,从而增加了这些功能。肌肉骨骼超声的发展与超声诊断技术的进步是同步的。各种换能器功能和快速图像处理的出现,以及评估血管和组织特性的能力,已经扩大并将继续扩大肌肉骨骼超声的作用。还应该指出的是,这些发展在很大程度上是由于一些有洞察力的人看到了这种发展中的技术在许多相关的临床肌肉骨骼问题上的潜在应用。精细的高分辨率图像,无论是深和小浅表肌肉骨骼解剖,评估血管在毛细血管水平和组织力学特性可以得到。超声也被认为是进行多种介入手术的首选方法。对这些技术发展的简要回顾,这些改进发生的时间线,以及对肌肉骨骼超声的影响如下。

Aim of the study: There is no consensus on the most suitable non-surgical treatment of chronic lateral elbow tendinopathy. The aim of this pilot randomized controlled trial was to evaluate the size of effect of ultrasound-guided percutaneous needle tenotomy. Material and methods: Three intervention arms were formed: 1) percutaneous needle tenotomy, hydrodissection, and physiotherapy; 2) hydrodissection and physiotherapy; and 3) physiotherapy alone. Patients with chronic lateral elbow tendinopathy were randomized. Clinical endpoints included multiple questionnaires after three months: Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), Numeric Rating Scale (NRS) pain at rest and during activity, and EuroQol 5D-5L (EQ-5D-5L). Results: Thirty patients were included of 128 screened. The QuickDASH score improved in the percutaneous needle tenotomy and physiotherapy group, but not in the hydrodissection group. The NRS pain at rest and during activity improved more in the percutaneous needle tenotomy (resp. –2 and –2) and hydrodissection (resp. –3 and –3) groups than in the physiotherapy (resp. +1 and –1) group. The EQ-5D-5L improved similarly in all groups. Conclusions: Patients receiv- ing percutaneous needle tenotomy and/or hydrodissection may show better results in terms of pain but not in their functional outcomes compared to those who received physiotherapy alone. The size of effect, however, is small, so a large sample size is needed for a future randomized controlled trial to further in- vestigate these results.
研究目的:对于慢性肘关节外侧病变的非手术治疗方法尚无共识。本试验的目的是评估超声引导下经皮针刺肌腱切开术的效果大小。材料与方法:形成三个干预臂:1)经皮针刺肌腱切开术、水解剖、物理治疗;2)水解剖和物理治疗;3)单独进行物理治疗。慢性肘关节外侧病变患者随机分组。临床终点包括三个月后的多项问卷调查:手臂、肩膀和手的快速残疾(QuickDASH),静止和活动时疼痛的数值评定量表(NRS),以及EuroQol 5D-5L (EQ-5D-5L)。结果:筛选128例患者,纳入30例。经皮针刺肌腱切开术和物理治疗组的QuickDASH评分有所改善,而水解剖组则无改善。静息时和活动时的NRS疼痛在经皮针刺肌腱切开术中得到了更大的改善。-2和-2)和hydrodissection(见。-3和-3)组比物理治疗组(p < 0.05)。+1和-1)组。EQ-5D-5L在所有组中都有类似的改善。结论:与单独接受物理治疗的患者相比,接受经皮针刺肌腱切开术和/或水解剖的患者可能在疼痛方面表现出更好的结果,但在功能方面却没有更好的结果。然而,效应的大小很小,因此未来的随机对照试验需要更大的样本量来进一步调查这些结果。

Soft tissue and osseous musculoskeletal infections are common but can be difficult to diagnose clinically. Signs, symptoms, and physical examination findings may be nonspecific, and laboratory values can be in- conclusive. The extent of disease may also be underestimated on physical examination. Soft tissue infections most commonly occur secondary to direct inoculation from broken skin and less frequently due to the seed- ing of the soft tissues from hematogenous spread, while osseous infections are more commonly due to he- matogenous seeding. Infections may also be iatrogenic, following surgery or other procedural interventions. High-resolution ultrasound is an extremely useful imaging modality in the evaluation of musculoskeletal soft tissue and joint infections, and can occasionally be used to evaluate osseous infections as well. Ultrasound can aid in the early diagnosis of musculoskeletal infections, allowing for prompt treatment, decreased risk of complications, and treatment optimization. Ultrasound is sensitive and specific in evaluating soft tissue edema and hyperemia; soft tissue abscesses; joint, bursal and tendon sheath effusions/synovitis; and subperi- osteal abscesses. This article describes the typical high-resolution grayscale as well as color and power Dop- pler ultrasound imaging findings of soft tissue infections including cellulitis, fasciitis, necrotizing deep soft tissue infection, pyomyositis, soft tissue abscess, infectious bursitis, and infectious tenosynovitis. Ultrasound findings of septic arthritis as well as osteomyelitis, such as subperiosteal spread of infection (subperiosteal abscess). are also reviewed. In addition, the use of ultrasound to guide fluid and tissue sampling is discussed.
软组织和骨骼肌骨骼感染是常见的,但临床上很难诊断。体征、症状和体格检查结果可能是非特异性的,实验室值可能是结论性的。体格检查也可能低估疾病的严重程度。软组织感染最常见的是继发于破损皮肤的直接接种,较少的是由于血液传播的软组织种子,而骨性感染更常见的是由于原生种子。感染也可能是医源性的,在手术或其他程序干预之后。高分辨率超声在评估肌肉骨骼软组织和关节感染方面是一种非常有用的成像方式,偶尔也可以用于评估骨骼感染。超声可以帮助肌肉骨骼感染的早期诊断,允许及时治疗,降低并发症的风险,并优化治疗。超声在评价软组织水肿和充血方面具有敏感性和特异性;软组织脓肿;关节、法氏囊和肌腱鞘积液/滑膜炎;骨周下脓肿。本文介绍了蜂窝织炎、筋膜炎、坏死性深部软组织感染、化脓炎、软组织脓肿、感染性滑囊炎和感染性腱鞘炎等软组织感染的典型高分辨率灰度、彩色和功率多普勒超声成像结果。超声检查发现脓毒性关节炎以及骨髓炎,如骨膜下扩散感染(骨膜下脓肿)。也进行了审查。此外,还讨论了利用超声引导液体和组织取样的方法。

Rheumatologic diseases are a widespread group of disorders affecting the joints, bones, and connective tissue, and leading to significant disability. Imaging is an indispensable component in diagnosing, assess- ing, monitoring, and managing these disorders, providing information about the structural and functional alterations occurring within the affected joints and tissues. This review article aims to compare the utility, specific clinical applications, advantages, and limitations of high-resolution ultrasound and magnetic reso- nance imaging in the context of rheumatologic diseases. It also provides insights into the imaging features of various types of inflammatory arthritis with clinical relevance and a focus on high-resolution ultrasound and magnetic resonance imaging. By understanding the comparative aspects of high-resolution ultrasound and magnetic resonance imaging, it is easier for the treating physicians to make informed decisions when selecting the optimal imaging modality for specific diagnostic purposes, effective treatment planning, and improve patient outcomes. The patterns of soft tissue and joint involvement; bony erosion and synovitis help in differentiating between various type of arthritis. Involvement of various small joints of the hands also gives an insight into the type of arthritis. We also briefly discuss the potential applications of emerging techniques, such as ultrasound elastography, contrast-enhanced ultrasound, and dual-energy CT, in the field of rheumatology.
风湿病是影响关节、骨骼和结缔组织的一组广泛的疾病,并导致严重的残疾。成像是诊断、评估、监测和管理这些疾病不可或缺的组成部分,提供有关受影响关节和组织内发生的结构和功能改变的信息。这篇综述文章旨在比较高分辨率超声和磁共振成像在风湿病中的用途、具体临床应用、优点和局限性。它还提供了不同类型的炎性关节炎与临床相关性的成像特征的见解,并专注于高分辨率超声和磁共振成像。通过了解高分辨率超声和磁共振成像的比较方面,治疗医生在为特定诊断目的选择最佳成像方式时更容易做出明智的决定,更容易制定有效的治疗计划,并改善患者的预后。软组织和关节受累模式;骨侵蚀和滑膜炎有助于区分不同类型的关节炎。手的各种小关节的参与也提供了一个深入了解关节炎的类型。我们还简要讨论了新兴技术在风湿病学领域的潜在应用,如超声弹性成像、对比增强超声和双能CT。
