PURPOSE To determine the accuracy of magnetic resonance (MR) imaging and MR arthrography in the detection and staging of lesions of the acetabular labrum. MATERIALS AND METHODS Fifty-seven hips of 56 patients with chronic hip pain and a strong clinical suspicion of labral lesions were examined with a three-dimensional gradient-echo sequence in the coronal(More)
OBJECTIVE Our purpose was to describe the appearance of the acetabular capsular-labral complex on MR arthrography and to correlate this appearance with surgical findings in adult patients and with gross anatomic findings in cadavers. SUBJECTS AND METHODS MR arthrography of the hip joint was performed in 40 patients and six cadavers. All patients underwent(More)
To assess of the value of conservative and operative treatment of osteochondritis dissecans of the knee, a multicenter study was performed. In 12 European countries, 798 cases of osteochondritis of the knee have been collected from 44 hospitals. Results were based on 452 patients with 509 affected knees with minimum follow-up was 1 year (mean follow-up, 3(More)
MR arthrography of the hip joint is usually performed after a conventional MRI has been obtained to rule out other pathologies of the hip joint as for instance bone marrow edema or osteonecrosis of the hip. MR arthrography is mainly performed as a very special investigation, and it is executed in most cases if the clinician asks for the diagnosis of a(More)
Based on the ultrasound investigation of 19,666 babies (1981-1988), 6341 of them directly at the maternity ward, we picked out the group of sonographically unstable or decentered hip joints, which must be treated instantly. Almost 50% of these hips did not show any clinical signs of instability! At follow-up the subgroup of sonographically screened hip(More)
The capsular-labrum-complex consists of the triangular fibrocartilaginous labrum, which is fixed at the bony acetabular ring and supported by the ligamentum transversum actetabuli in the caudal part. In a normally developed and correctly orientated acetabulum, the femoral head is symmetrically covered by the contact area of the lunate surface. The vertical(More)
Effective prevention of late dysplastic dislocation of the hip (DDH) has become a reality since reliable diagnosis has been possible at an early stage by means of the original sonographic method according to Graf. A correct sonographic diagnosis must be instantly followed by adequate, biomechanically rational, and consistent therapeutic management and(More)
Concomitant pathologies (labral lesions, intra-/extra-osseous ganglia and stress bone marrow edema) in adult residual hip dysplasia (RHD) might influence the outcome of conservative hip surgery. The aim of our prospective clinical study was to assess the value of preoperative MR arthrography in diagnosing concomitant lesions and in making surgical decisions(More)
