PURPOSE To evaluate the diagnostic value of magnetic resonance (MR) imaging in patients with clinical suspicion of scaphoid fractures and normal initial plain radiographs. MATERIALS AND METHODS MR imaging was performed within 7 days after trauma in 42 patients with clinical suspicion of scaphoid fractures and normal plain radiographs. T1-weighted(More)
BACKGROUND The continuous increase in the number of fractures of the proximal femur is directly attributable to the worldwide increase in life expectancy. The standard version of the Gamma Interlocking-Nail (standard Gamma nail [SGN], 200-mm length, 10-degree valgus curvature, two distal locking bolts) was designed because of the demands in orthopedic hip(More)
The gamma nail is a temporary implant characterised by a limited life expectancy under continuous dynamic stress. We reviewed a series of 839 patients with gamma nail stabilisation and found two fatigue fractures (0.2%) at the aperture of the distal locking holes. This complication has not been described in the literature. Metallurgic and scanning electron(More)
PURPOSE Our goal was to evaluate the visibility and incidence of traumatic abnormalities of the sinus tarsi in patients with acute ankle sprain injuries and compare these findings with the extent of lateral ankle ligament injuries on MRI. METHOD Sixty athletically active patients (aged 18-45 years) with recent inversion trauma (< or = 7 days) underwent(More)
An experimental study was performed on 20 cadaveric human proximal femurs to investigate both the reproducibility of their mechanical behavior under uniaxial compression and the correlation of mechanical properties with geometric dimensions and bone density. These variables were assessed by radiography, physical measurement, and dual-energy X-ray(More)
PURPOSE The aim of this study was to establish diagnostic criteria for meniscal subluxation, and to determine whether there was any connection between meniscal subluxation and other common meniscal and knee-joint abnormalities. MATERIAL AND METHODS The normal position of the meniscal body was assessed in 10 asymptomatic volunteers. MR signs of meniscal(More)
Occult fractures of the scaphoid bone occur frequently and may lead to nonunions. In a prospective blind study, we performed magnetic resonance imaging (MRI) examinations on 32 patients who had sustained a wrist injury and in whom a scaphoid fracture was clinically suspected, but could not be confirmed on the original set of two routine and four scaphoid(More)
There has been a marked increase in the incidence of pelvic fractures over the last few years. Associated injuries to the urogenital and vascular system as well as nerve injuries worsen the prognosis. Over a five year period 126 patients with severe pelvic trauma were treated. Out of these 39 (30.9%) sustained additional peripelvic injuries and represent(More)
We evaluated the reliability of the radiographic talar tilt test by MRI examinations in 112 athletes with injuries to the lateral ligaments of the ankle. 25 athletes with a talar tilt > 15 degrees were treated operatively. Intraoperative findings and the talar tilt test were compared with MR imaging results. Our results suggest that MRI is a reliable method(More)
We retrospectively analyzed 1334 patients who were implanted standard gamma interlocking nails (SGN) to stabilize trochanteric femoral fractures over the years 1992-1998. Reoperation to remove the nails was performed in 37 patients, in 9 of them purely because of pain. Three out of these 9 patients with removed SGN suffered femoral neck fractures in the(More)
