Introduction. In patients with shoulder pain one of the important initial determinations is to assess the integrity of the rotator cuff. Clinical examination is often inconclusive. Compared with MRI and arthrography, ultrasound allows dynamic evaluation, is non-invasive, less expensive, less time-consuming and more acceptable to patients. The aim of the present study was to evaluate the accuracy of high resolution shoulder

We prospectively studied 26 consecutive patients with clinically documented sensory or motor deficiency of a peripheral nerve due to trauma or entrapment using ultrasound, and in 19 cases surgical exploration of the nerves was undertaken. The ultrasonographic diagnoses were correlated with neurological examination and the surgical findings. Reliable visualisation of injured nerves on

Acute lateral ankle sprain accounts for 85% of sprains. The lateral sprain is associated with other ligament injuries e.g. medial and syndesmosis sprain. Long-term, approximately 20% of acute lateral sprains develop into chronic lateral ankle instability (CLAI) which includes persistent pain, and recurring ankle sprains. This study evaluated the grade of an ankle ligament injury by

Aims. Our aim was to describe the mid-term appearances of the repair
process of the Achilles tendon after tenotomy in children with a
clubfoot treated using the Ponseti method. Patients and Methods. A total of 15 children (ten boys, five girls) with idiopathic
clubfoot were evaluated at a mean of 6.8 years (5.4 to 8.1) after
complete percutaneous division of the Achilles tendon. The contour
and subjective thickness of the tendon were recorded, and superficial
defects and its strength were assessed clinically. The echogenicity,
texture, thickness, peritendinous irregularities and potential for
deformation of the tendon were evaluated by

Total knee arthroplasty (TKA) is one of the most successful surgeries to relieve pain and dysfunction caused by severe arthritis of the knee. Despite developments in prophylactic methods, deep venous thrombosis (DVT) and pulmonary embolism (PE) continue to be a serious complication following TKA. Otherwise DVT/PE is known to be a relatively low incidence in Asian patients, its accurate incidence is still controversial. Therefore, we prospectively investigated the incidence of DVT/PE after primary TKA by contrast enhanced computed tomography (CE-CT) and venous
Lateral femoral cutaneous nerve (LFCN) injury is a potential complication after the direct anterior approach for total hip arthroplasty (DAA-THA). The aim of this study was to determine how the location of the fasciotomy in DAA-THA affects LFCN injury. In this trial, 134 patients were randomized into a lateral fasciotomy (n = 67) or a conventional fasciotomy (n = 67) group. This study was a dual-centre, double-blind, prospective randomized controlled two-arm trial with parallel group design and a 1:1 allocation ratio. The primary endpoint was the presence of LFCN injury, which was determined by the presence of numbness, decreased sensation, tingling, jolt-like sensation, or pain over the lateral aspect of the thigh, excluding the surgical scar, using a patient-based questionnaire. The secondary endpoints were patient-reported outcome measures (PROMs) using the Western Ontario and McMaster Universities osteoarthritis index (WOMAC), Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire (JHEQ), and the Forgotten Joint Score-12 (FJS-12). Assessments were obtained three months after surgery.Aims

Introduction. In Mid-Europe developmental dysplasia of the hip (DDH) is diagnosed using the sonographic hip screening described by Graf. To learn the necessary standards three courses are mandatory. However, little is known about learning curves and measurement errors of doctors at different levels of training and experience. Material and Methods. Between 1997 and 2002 participants of the basic, advanced and final hip ultrasonogra-phy course were evaluated by a questionnaire and 34 normal and pathological sonograms. They were asked to measure the alpha and beta angle. “Normal” angles of each hip were created through the mean values of two experienced course organizers. Results. 186 doctors (40% orthopedic surgeons, 60% pediatricians) were evaluated. The group included 20% interns, 60% residents and 20% consultants. An average time of 6.3 months lay between the basic and the advanced, and of 16.7 months between the advanced and the final course. The evaluation of the sonograms according to Graf showed major inter-observer differences of up to 30°. Participants had more difficulties in evaluating a correct beta angle than an alpha angle. Sonographic pictures of minor quality and pathological hips produced more difficulties than pictures of Graf type I and II hips. In the basic course all measurements showed an average difference of 3,6°, in the advanced course of 3,1° and in the final course of 4,2°. The number of examinations between courses did not correlate with good measurements. Conclusion. Even participants of all three courses seem to develop major systemic errors if
Aims: The purpose of this study is to evaluate the possible utility of a low-cost radiation-free technique for predicting degenerative changes in the lumbar spine. Methods: In 117 patients with low back pain or pain in the lower limb, ultrasonographic parameters (speed of sound, broadband ultrasound attenuation, stiffness) of the calcaneus were correlated with (1) evidence for degenerative changes and stenosis on magnetic resonance scans of the lumbar spine and (2) Oswestry Low Back Pain Disability Questionnaire Score. Linear and logistic regression as well as ROC curves analyses were used to evaluate the correlation. Results: Lumbar spine stenosis was associated with elevated calcaneal ultraso-nographic parameters. For the identiþcation of a narrowing of the lumbar spinal canal below 100mm2 of dural sac crosssectional area, speed of sound showed an 89% sensitivity in males older than 60. In these patients, we also found a signiþcant positive correlation between ultrasonographic parameters and scores on a MRI-based degenerative scale. No signiþcant correlation was found between disability score and lumbar spine degeneration or ultrasonographic parameters. Conclusions: Calcaneal
Introduction and purpose: Our aim was to determine a morphometric relation between the long head of the brachial biceps and the bicipital groove with respect to the subscapular tendon, and its repercussion on functional imbalance of the shoulder. Materials and methods: For this analytical observational crossover study we took a sample of 30 right-handed, sedentary, duly informed male subjects. The morphometric study was carried out with
Previous investigations have postulated that the asymmetry of the breasts in female adolescents may be linked with the development of right convex thoracic scoliosis, although there is no correlation between breast asymmetry and curve type or scoliosis magnitude. This breast asymmetry is supposed to be linked with anatomic and functional asymmetry of the internal mammary artery that is the main supplier to the mammary gland. However, no measurements of anatomic and haemodynamic parameters of internal mammary artery have been made to justify or to reject the hypothesis of asymmetric blood flow volume to the breasts and costosternal junction in female adolescent scoliotics. Twenty female adolescents with right thoracic scoliosis and 16 comparable female individuals without spine deformity were included in this study. Standing roentgenograms of the whole spine were made in all scoliotics to measure scoliosis curve, vertebral rotation and concave and convex rib-vertebra-angle at three vertebrae (apical, one level above and one below the apical vertebra).
