OBJECTIVE We report 54 patients with histologically evaluated musculoskeletal masses who underwent grey-scale and contrast-enhanced ultrasound (CEUS), followed by ultrasound-guided biopsy. We hypothesise that the definition of a CEUS-based enhancement pattern improves the characterisation of tumour malignancy. METHODS Fifty-four patients with soft-tissue(More)
High resolution ultrasound (HR-US) including color Doppler ultrasound (CD-US), power Doppler ultrasound (PD-US), and spectral wave analysis (SWA), is a broadly available, non-invasive and relatively low-cost modality without ionizing radiation. It is increasingly used for initial assessment of an ambiguous musculoskeletal soft-tissue lesion and for(More)
PURPOSE Anesthetic infiltration of the pudendal nerve at the ischial spine can relieve perineal pain in cases of compression or distention. The aim of our study was to look for a real-time, visually controlled infiltration technique using ultrasound. METHODS Fifty-three volunteers were examined in a prone position using a 3.5-MHz curved-array probe in(More)
OBJECTIVE To assess the feasibility of ultrasonography of femoral nerves in a cadaveric specimen, healthy volunteers, and patients. METHODS In 1 unembalmed cadaveric specimen (female, 90 years) and 20 healthy volunteers (9 male and 11 female, 18-50 years; n = 40 scans), the topographic features, cross-sectional shapes (oval or triangular), and(More)
OBJECTIVE Traumatic knee dislocation needs immediate surgical repair to restore joint function. A concomitant traction injury of the peroneal nerve is reported to exist in up to 25% of cases and is often overlooked initially. In patients with major nerve lesions, immediate surgical nerve repair might be necessary to avoid irreversible loss of neural(More)
Thirty women (mean age 49 years; range 33-74) with mild to moderate pelvic relaxation and genuine stress incontinence underwent preoperative urodynamic studies. Biopsy specimens from the levator ani muscles during vaginal hysterectomy and repair were evaluated for the number and the individual diameters of type I (slow-twitch) and type II (fast twitch)(More)
PURPOSE We report the topographic relationship of the pudendal nerve to the accompanying pudendal vessels and the ischial spine and provide the basics for an ultrasonographic depiction of these structures. METHODS Twenty-nine female and 29 male adult human cadavers were positioned prone to expose the deep gluteal region. In 58 left and 58 right pelves the(More)
Our objective was to evaluate the usefulness of CT virtual preoperative planning in the surgical repositioning of malunited distal radius fracture. Eleven patients with malunited distal radius fracture underwent multislice CT of both wrists. A preoperative workup was performed in a virtual reality environment created from the CT data sets. Virtual planning(More)
Peripheral nerve tumors are not frequent, but due to their association with a nerve they are somewhat special. They may be encountered incidentally during evaluation of a soft-tissue mass or when a nerve lesion is clinically suspected and the recognition of such a lesion and its differential diagnosis is key for successful therapy and patient prognosis. As(More)
OBJECTIVE To describe ultrasonographic findings in 4 patients with supinator syndrome (i.e., deep branch of the radial nerve). METHODS Four patients with weakness and pain in their forearm underwent ultrasonographic examination with subsequent electroneurographic testing and surgical nerve inspection. Normal measurements of the deep branch of the radial(More)
