Cross-sectional cuts through the acetabulum of a cadaveric pelvis were obtained to evaluate the bony anatomy. There are six slices of 1 cm thickness which define the acetabulum. This information has been important to us primarily to assess acetabular fractures with computerized tomography.
Twenty-four patients have been evaluated to demonstrate the role of computerized tomography (CT) in assessment of acetabular fractures. CT is important in defining the articular dome, intraarticular and femoral head abnormalities, associated sacroiliac damage and soft-tissue injury. The CT examination can be obtained with minimal additional discomfort to the patient.

Periosteal chondroma is an uncommon benign cartilagenous lesion, and its importance lies primarily in its characteristic radiographic and pathologic appearance which should be of assistance in the differential diagnosis of eccentric lesions of bones. The pathologist must be aware of this tumour because at a histologic level, it may closely resemble a more ominous cartilagenous lesion. He can exclude this lesion in a differential diagnosis of a primary cartilagenous bone neoplasm by familiarity with the clinical and radiological appearance of the lesion. In all cases reported so far, treatment has been that of wide local excision. There are no recorded cases of metastases in follow-up periods ranging up to 8 years after surgery. In those cases where local recurrences were reported, inadequate initial excision is the admitted cause, and subsequent re-excision led to complete eradication of the residual tumour.
