Musculo skeletal ultrasound

The use of Mesenchymal Stromal Cells (MSCs) in orthopedic practice has recently and rapidly acquired an important role. Therapies based on the use of MSCs for the treatment of acute injuries as well as chronic inflammatory disorders are gradually becoming clinical routine. These cells have demonstrated intriguing therapeutic potentialities (i.e.: inflammation control, tissue regeneration and pathological scar prevention), that have been taken into consideration for use in both human and veterinary medicine...

BACKGROUND: Venous thromboembolism (VTE) is a frequent complication of major orthopaedic surgery; prolonged prophylaxis with anticoagulants is standard of care. However, late manifestation of VTE is common and little is known about the predictors of late deep vein thrombosis (DVT) and the distribution of proximal and distal DVT and isolated calf muscle vein thrombosis (MVT). PATIENTS AND METHODS: 482 patients admitted to a rehabilitation clinic (RC) after total hip or knee replacement (THR; TKR) or hip fracture surgery (HFS) underwent complete compression ultrasound (CCUS) screening for VTE within 72 hours after admission into RC...

Incidence of urolithiasis is on the rise due to climatic changes especially global warming.The pain due to presence of ureteric stone is a well known identity but many times it may be asymptomatic or even masked by concurrent presence of backache. In the present article, we describe the case of a 43-year-old male who came to the clinic for treatment of backache persisting for more than two years. The patient complained of backache two years back for which he was treated with analgesics and physiotherapy which relieved his pain...

Recurrent haemarthrosis is the final cause of haemophilic arthrosic disease in haemophilia patients. Therefore, it is essential to diagnose it early, both clinically and by imaging. In addition, haemophilia patients experience chronic synovitis, joint degeneration, muscle haematoma and pseudotumours. The objective of this article is to highlight the value of ultrasounds in the diagnosis and control of the evolution of musculo-skeletal problems in haemophilia patients. To this end, we have performed a literature search in the PubMed, Web of Science(®) (WOS) and SciVerse bases, using the following keywords: hemophilia or haemophilia and ultrasonography (US), ultrasound, echography and sonography...

Muscle performance is closely related to the architecture and dimensions of the muscle-tendon unit and the effect of maturation on these architectural characteristics in humans is currently unknown. This study determined whether there are differences in musculo-tendinous architecture between adults and children of both sexes. Fascicle length and pennation angle were measured from ultrasound images at three sites along the length of the vastus intermedius, vastus lateralis, vastis medialis and rectus femoris muscles...

Ultrasound can be used to study tendon movement. However, measurement of tendon movement is mostly based on manual tracking of anatomical landmarks such as the musculo-tendinous junction, limiting the applicability to a small number of muscle-tendon units. The aim of this study was to quantify tendon displacement without anatomical landmarks using a speckle tracking algorithm optimized for tendons in long B-mode image sequences. A dedicated two-dimensional multi-kernel block-matching scheme with subpixel motion estimation was devised to handle large displacements over long sequences...

Hip joint dysplasia is the commonest disorder of the musculo-skeletal system in childhood. The overall success of treatment is highly dependant on the early diagnosis. Clinical tests and ultrasound are the most popular methods for early diagnosis. The aim of our study was to estimate the possibilities of both methods for correct early diagnosis. A group of 1200 newborns was studied and the results were analyzed. Clinical methods of Ortolani and Barlow were used, as the ultrasound method according to Graf's technique...

BACKGROUND: Ankle pain and swelling following sports injuries are common presenting complaints to the accident and emergency department. Frequently these are diagnosed as musculoskeletal injuries, even when no definitive cause is found. Vascular injuries following trauma are uncommon and are an extremely rare cause of ankle swelling and pain. These injuries may however be limb threatening and are important to diagnose early, in order that appropriate treatment can be delivered. We highlight the steps to diagnosis of these injuries, and methods of managing these injuries...

OBJECTIVE: To evaluate the effect of bridged free latissimus dorsi musculo-cutaneous flap on repairing of soft tissue defect in the lower extremity. METHODS: Seven patients with extensive soft tissue defects in the lower extremities were enrolled in the clinical investigation. The defects were all repaired with bridged free latissimus dorsi musculo-cutaneous flaps. The condition of the blood vessels in the flaps and the healthy extremities was examined with ultrasound Doppler before the operation to assure the blood circulation of grafted flap...

The aim of the study was to evaluate the occurrence of the anatomical variations of the musculotendinous junction of the flexor carpi ulnaris (FCU) muscle and the variations of its insertion onto the pisiform. One hundred cadaver specimens preserved according to Thiel's method were assessed. Following careful dissection, the distance between the musculotendinous junction and the pisiform and the width of the muscle belly were determined. Three typical anatomical variations were found: 1) a large muscle belly running distally almost to the insertion onto the pisiform; 2) the muscle belly ending more proximally, with some large fibres running parallel to the tendon and almost reaching the pisiform; 3) the musculotendinous junction ending more proximally, with only single fibres continuing distally...

AIM: We demonstrate a technique for examining the hip joint sonographically in a standardised way using sectional planes corresponding to the guidelines provided by the work group "Sonography of the Musculo-Skeletal System" of the German Society of Ultrasound (DEGUM). MRT-scans were used as a comparative standard. METHOD: The ultrasound examination was performed in the following standardised way: a transversal and longitudinal scan were done in the ventral region and additionally a longitudinal scan in the lateral region...

Musculoskeletal ultrasound is a rapidly expanding diagnostic field. High frequency transducers with high spacial resolution make it possible to demonstrate superficial soft tissue structures such as tendons, muscles, ligaments and even, under certain circumstances, fractures and periosteum. A case is presented where ultrasound clearly visualised periostal interposition in a distal tibial epiphysiolysis in an eight year-old boy, and some aspects of ultrasound in musculo-skeletal imaging are discussed.

A number of ultrasonic methods are available for the detection of tissue motion as it occurs physiologically in the body. The detection of echoes from within the body in less than 1 ms after the initial transmission of ultrasound and the Doppler effect have enabled a range of instrumentation to be developed. The subject owes a great deal to advances in transducer design, electronics and computer technology. Over many years fast B-mode imaging and M-mode traces of boundary position versus time have been the main clinical tools...

Until recently, few articular indications for sonographic imaging have been widely accepted. However, concerns about imaging costs are expanding its role in musculo-skeletal pathology. Valuable diagnosis insight are readily obtained with recently available high frequency transducers. Ultrasound may be utilised following clinical examination as an efficient tool in the diagnosis and follow-up of various synovial disorders. Dynamic studies of articular structures as they move, is a significant advantage over other diagnosis modalities...

Following the essentially 'hands-on' origin of the physiotherapy profession a century ago, the range of techniques available to practitioners has expanded considerably. While this expansion of techniques has been of research interest, the main focus has been upon individual techniques, thus neglecting the fundamental question of the use of techniques in combination. In addition, researchers have tended to treat the profession as homogeneous, thus overlooking possible differences in technique usage. The present study addressed these questions...

Sonography has become a reliable diagnostic method in musculo-skeletal diseases. It allows a simple and noninvasive examination of joints and soft tissues. Especially in rheumatic diseases meaningful findings can be obtained. In the present study first results of three-dimensional (3D) sonography of the musculo-skeletal system are reported. The method was first validated by examining healthy test persons and criteria for regular findings were defined. In the second part of the study an unselected group of patients with inflammatory and noninflammatory joint and soft tissue diseases were examined and the obtained results were compared with the findings of the conventional real-time sonography...
