STUDY DESIGN A prospective clinical study. OBJECTIVE To investigate the dynamic causative factor in the pathogenesis of myelopathy in patients with cervical ossification of the posterior longitudinal ligament (OPLL) using kinematic computed tomography (CT) myelography. SUMMARY OF BACKGROUND DATA Kinematic CT myelography is useful for dynamically evaluating the cervical spine with high-resol...

There is increasing global awareness of adverse reactions to metal debris and elevated serum metal ion concentrations following the use of second generation metal-on-metal total hip arthroplasties. The high incidence of these complications can be largely attributed to corrosion at the head-neck interface. Severe corrosion of the taper is identified most commonly in association with larger diame...

OBJECTIVE To determine if there is evidence of levator ani atrophy in primiparous women. METHODS This was a prospective observational cohort study of 202 primiparous women recruited between November 2006 and March 2008. Translabial ultrasound volumes were obtained at 36-38 weeks' gestation and at a mean of 4.5 months postpartum. Peripartum changes in bladder neck elevation and reduction of an...

Multiple pilosebaceous cysts include the entities of steatocystoma multiplex and eruptive vellus hair cysts (EVHCs). Multiple pilosebaceous cysts are proposed to be one entity originating in the pilosebaceous duct, since steatocystoma multiplex and EVHCs are frequently present concomitantly and are caused by a cystic change in the same pilosebaceous duct. Here, we describe a patient with yellow...

the most common metastatic sites for colorectal carcinomas include the liver, lungs, brain, bones and peritoneal surfaces. in this report, a case of sigmoid colon carcinoma presented with cervical lymphadenopathy was detected with the help of pet/ct. a 57 year-old male presented with a complaint of swelling on the left side of his neck. ultrasonographic examination of the neck revealed three hy...

The optimum location and diameter, of an entry hole for an intramedullary nail, in the upper proximal femur, is investigated in this article. A comparative study for five different entry hole positions and seven different hole diameters at each position, has been pursued. The entry holes were located at the tip of the trochanter, at the superior, anterior and posterior parts of the lateral neck...

OBJECTIVES This study was conducted with the purpose of evaluating the inter-session reliability of new software to measure the diameters of the cervical multifidus muscle (CMM), both at rest and during isometric contractions of the shoulder abductors in subjects with neck pain and in healthy individuals. METHOD In the present study, the reliability of measuring the diameters of the CMM with ...

Metal-on-metal hip resurfacing offers some potential for total hip arthroplasty (THA) in the young patient. However, short- and intermediate-term results of the currently available implants have failed to demonstrate advantage over conventional THA. The risks of femoral neck fracture or avascular necrosis have been disappointing early limitations of the procedure. The Australian Joint Registry ...

Introduction: Knowledge about the different diameters of the head and neck of femur is essential in orthopedic surgery for prosthesis and nail application. The aim of this study was to evaluate the average FNA in the young Egyptians and the effect of age on it. Also, matching sex and side differences of the angle were done by using CT. In addition, the different growth parameters of the proxima...

Objectives: Volume assessment in head and neck squamous cell carcinoma (HNSCC) becomes an increasing important clinical parameter in treatment planning and response control. Various authors showed a significant impact of tumor volume on outcome and local control. In this study we compared the “gold standard”, the diameter based approach, with segmentation based approaches Methods: The segmentat...
