The prevalence of absence of the palmaris longus muscle in the Bahraini population  

British Library Electronic Table of Contents (United Kingdom)

Abstract Absence of the palmaris longus muscle has been well documented in several populations at a prevalence rate ranging between 2.2 and 63.9% which varies according to race, sex, and side of the body. There is little documentation of the prevalence of absence of this muscle from populations in the Arabian Gulf region. We examined 1,043 subjects, 3 85 years old, from the Kingdom of Bahrain for the presence or absence of the palmaris longus muscle using the conventional test for the presence of this muscle. Statistical analyses investigated the association of muscle absence with sex, hand dominance, and laterality. The palmaris longus muscle was absent in 36.8% of subjects. Bilateral absence (19%) was more common than unilateral absence (17.9%) with preponderance in female subjects. The ...

Generalization of proposed tendon friction correlation and its application to PCCV structural analysis  

Energy Technology Data Exchange (ETDEWEB)

The present paper dealt with the extension of tendon friction coefficient correlation as a function of loading end load and circumferential angle, proposed in the former paper. The extended correlation further included the effects of the number of strands contacted with sheath, tendon diameter, politicization of tendon and tendon local curvature. The validity of the correlation was confirmed by several published measured data. The structural analysis of middle cylinder part of 1/4 PCCV (Prestressed Concrete Containment Vessel) model was conducted using the present friction coefficient correlation. The results were compared with the analysis using constant friction coefficient, focused on the tendon tension force distribution. (author)

Pericardio-diaphragmatic avulsion and concomitant rupture of the central tendon of the diaphragm.  

Science.gov (United States)

Two patients, treated for blunt thoracoabdominal trauma with ruptured diaphragm and concomitant avulsion of the pericardial sac in its entirety from the central tendon of the diaphragm, are presented. We do not think this entity has been reported before. We explain this type of lesion on the basis of embryological development of the pericardium at the level of the central tendon of the diaphragm.

Fixation Techniques for Split Anterior Tibialis Transfer in Spastic Equinovarus Feet  

Science.gov (United States)

Equinovarus of the foot is the most common lower extremity deformity following traumatic brain injury. We evaluated outcomes of the split anterior tibialis tendon transfer (SPLATT) for correction of equinovarus in 47 patients with hemiplegic traumatic brain injury and specifically studied differences in outcomes with two tendon fixation techniques. Seventeen patients constituting Group I underwent fixation with one technique and 30 constituting Group II had another technique. Patients in both groups had appropriate procedures based on dynamic electromyography and gait analyses. Both groups were demographically comparable. All 47 feet were corrected to plantigrade position. Thirty-six of 47 patients became brace-free at final followup. There was a notable decrease in the use of ambulatory aids and ambulatory status improved in both groups. There were three fixation-related complications in Group I and none in Group II. Surgical correction of the ...

Split anterior tibial tendon transfer for varus equinus spastic foot deformity  

British Library Electronic Table of Contents (United Kingdom)

Spastic equinovarus foot deformity commonly occurs after stroke or head trauma. Management by split anterior tibial tendon transfer to the lateral border of the foot was chosen by the authors. The purpose of that work was to assess the reliability of this method to improve patient's functional autonomy and investigate the relationship between the initial clinical examination findings and the quality of the functional results. 84 feet, operated in 82 patients out of 130, of mean age 46 years, were reviewed at a mean follow-up of 65 months. Very few complications were observed. Toe deformities remain a commonly associated problem. 80 patients were able to walk barefoot, 74 reported an increase in their walking distance, and 73 could regularly wear normal shoes. There is a strong relationship...

Assessment of the supramolecular structures presents into biological samples by SAXS technique;Avaliacao das estrutras supramoleculares presentes em amostras biologicas atraves da tecnica de SAXS  

Energy Technology Data Exchange (ETDEWEB)

In this work was made an assessment of the supramolecular structures presents into human breast tissue normal and pathological samples, as well as into two types of animals samples (tendon chicken and pork fat) using the small angle x-ray scattering (SAXS) technique. The scattering profiles of the samples were determined at the momentum transfer range O.150nm{sup -1}<=5:q(=4pi.sin({theta}/2)/{lambda})<=8.500nm{sup -1}. In this range, it was possible identify structures corresponding to collagen fibrils (glandular tissue) and to triacylglycerides (adipose tissue) from the correlation between the information extracted from the human breast tissues scattering profiles and those extracted from animals samples.

CT versus MRI in the study of the articular diseases of the knee  

International Nuclear Information System (INIS)

The authors present a comparison between the diagnostic accuracy of Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) in the articular pathologies of the knee. CT and MRI were performed in 30 patients who subsequently underwent surgery. CT and MRI results were compared on three bases: technique, definition of normal anatomy, and diagnostic accuracy. CT allowed a standardization of the technique, while MRI was superior in defining normal anatomy - especially in the study of capsulo-ligamentous structures. In all cases the use of both CT and MRI allowed a correct diagnosis, showing the site, extent and gravity of the lesion. CT proved to be superior to MRI in 4 cases, while MRI corrected CT diagnosis in 11 cases; in 15 patients both techniques had the same diagnostic accuracy. Meniscal tears were better identified by CT, while MRI was superior in the detection of ligamentous lesions and in the characterization of PVNS and tendinitis of the patellar ...

Special phased array applications for pipeline girth weld inspections  

Energy Technology Data Exchange (ETDEWEB)

Pipeline automated ultrasonic testing (AUT) uses fully automated equipment that travels around a pipe on a welding band in a linear scan to allow array pulses to provide ultrasound information on weld zones. Pipeline AUT is also used for zone discrimination as well as with special calibration blocks, dual gate output displays, and rapid defect sizing. AUT allows for the inspection of welds soon after completion, and can save construction costs by process control when combined with engineering critical assessment (ECA) to minimize rejection rates. Ultrasonic phased arrays (UPA) use an array of elements that are all individually wired, pulsed, and time-shifted. Elements are pulsed in groups of approximately 16 elements at a time for pipeline welds. Phased arrays can be used to combine electronic scanning, sectorial scanning and precision focusing to give a practical combination of displays. Optimum angles can be selected for welds and other components, and the electronic scanning ...

Injuries of the tibio-talar joint and preoperative planning. Verletzungen des oberen Sprunggelenks aus unfallchirurgischer Sicht  

Energy Technology Data Exchange (ETDEWEB)

The treatment of bony, osteochondral, and ligamentous injuries of the tibio-talar requires precise preoperative planning by radiological investigation. This is essential to a correct understanding of the underlying pathology and will allow a proper classification of the injury, which is the basis of treatment. Conventional radiography using anteroposterior and lateral X-rays with comparative views of the noninjured side and, if necessary, rotated spot views and tomography are of high value especially in osteochondral fractures of the talus. Intraoperative control images in both planes after osteosynthesis are mandatory. For evaluation of the postoperative course and severity of arthrosis formation, the classification system of Bargon has proved its worth. In addition, tomography of the tibio-talar joint in two planes is useful especially in tibial pilon fractures, some malleolar fractures, and peripheral talar fractures. In talar fracture dislocations with concomitant compartment ...
