The position of 119 pedicle screws was assessed on plain antero-posterior and lateral radiographs taken immediately post-operatively and at 3 months' follow-up. The readings of five independent observers were compared with the “gold standard” of CT reconstructions. The position of only 41 % of implants (range 14%–56%) was assessed correctly on the plain(More)
OBJECTIVE The aim of this article is to describe the high-resolution CT (HRCT) findings in mild cases of fat embolism syndrome (FES). MATERIAL AND METHODS Nine patients with FES were examined with HRCT of the lungs (collimation, 1 mm/edge-enhancement algorithm). The median age of the patients was 26 years (range, 17 to 35 years). Five cases were included(More)
OBJECTIVE A previous study of radiofrequency neurotomy of the articular branches of the obturator nerve for hip joint pain produced modest results. Based on an anatomical and radiological study, we sought to define a potentially more effective radiofrequency method. DESIGN Ten cadavers were studied, four of them bilaterally. The obturator nerve and its(More)
OBJECTIVE The block of the obturator nerve is used in pain medicine mostly for the management of acute pain after lower limb surgery or for chronic hip pain. The aim of this study was to define an injection technique based on an anatomical investigation and a magnetic resonance (MRI) analysis. DESIGN Ten cadavers were studied, four of them bilaterally.(More)
Background. A nonrecognized pneumothorax (PTX) may become a life-threatening tension PTX. A reliable point-of-care diagnostic tool could help in reduce this risk. For this purpose, we investigated the feasibility of the use of the PneumoScan, an innovative device based on micropower impulse radar (MIR). Patients and Methods. addition to a standard(More)
