Pre-operative evaluation for uncemented hip arthroplasty. The role of computerised tomography.
We have studied the role of computerised axial tomography in the assessment of the acetabulum before an uncemented Mittelmeier arthroplasty was performed in 20 patients. In the absence of gross anatomical abnormality, computerised tomography did not provide additional information, but in eight patients it was useful in determining adequacy of acetabular depth, anterior acetabular cover, and thickness of the anterior and posterior walls. In these patients, the CT scans provided information which was not available from plain radiographs and greatly assisted in pre-operative planning.
