Abstract
PDF - PURPOSE
In the evaluation of acetebular fractures, conventional radiography is limited by distortion, magnification, and overlap of fracture fragments. Computed tomography(CT) has already been shown to be superior in this field. The purpose of this paper was to use 3D reformations for classification of acetabular fractures and planning of operation.
MATERIALS AND METHODS
From July 1994 to December 1998, we reviewed 40 acetabular fractures. We evaluated fractures as plain X-ray(inlet & outlet view, AP view, obturator foramen & illiac wing view), axial CT with 3 mm slices, and 3D reformations. We classified fractures by classification of Letournel.
RESULTS
32 cases of 40 cases were displaced fractures, We recognized fracture easily in 3D reformations. 12 cases were posteior wall fracture. 9 cases were both column frctures. We interpretated both column fractures difficultly in plain X-ray, but we had many informations about rotation & displacement of fracture fragment by 3D reformations. Undisplaced fracture was 8 cases. We interpretated undisplaced fracture difficultly in 3D reformations and distinguished difficultly from normall 3D reformations.
CONCLUSION
3D reformations were useful for analysis of complex displaced fracture but not useful for analysis of undisplaced fracture. Acetabular internal oblique view was useful for analysis of quadrilateral space & posterior wall fractures. Acetabular external view was useful for decision of surgical approach.

Abstract

- The factors that determine whether a proximal femoral fracture is neck or trochanteric area are a matter of controversy. So we studied the BMD(bone mineral density) and the morphology of the contralateral femur in subcapital fracture and intertrochanteric fracture(Boyd - Griffin Type I,II). The bone density of femoral neck, Ward's triangle and trochanteric region was measured by dual energy X-ray absortiometry(DEXA) in 41 patients with femoral neck fracture value and fracture type in same patients, we calculate the femoral neck length from the plain X-ray film. The results were as follows. 1. The ratio of BMD in the neck and trochanter area was higher in the trochanter fracture group. 2. The level of BMD of the trochanter fracture group was lower than the neck fracture group in all opints of measurement. 3. In the measurement of femoral neck length at plain X-ray film, the neck length of trochanter fracture group was longer than the neck fracture group. It may be that difference in BMD and femoral neck length is related to the site at which a proximal femoral fracture occurs.
