[Value of 3D CT in diagnosis and treatment of fractures of the tibial plateau].

A precise classification and an optimal understanding of tibial plateau fractures are the basis of a conservative treatment or adequate surgery. The aim of this prospective study is to determine the contribution of 3D CT to the classification of fractures (comparison with standard X-rays) and as an aid to the surgeon in preoperative planning and surgical reconstruction. Between November 1994 and July 1996, 20 patients presenting 22 tibial plateau fractures were considered in this study.

Three-dimensional morphology of the proximal femur.

In the field of uncemented hip arthroplasties, secondary biologic fixation of femoral implants depends directly on the quality of the primary stability. Metaphyseal filling and a good fit between the implant and the proximal femur improve initial stabilization and optimize the transmission of forces to the bone. Precise knowledge of the three-dimensional femoral shape is essential to the design and selection of adapted implants.

[External fixator in severe traumatic injuries of the pelvis: results apropos of 20 consecutive cases].

From August 91 to December 94, 20 external fixators were used for severely injured patients (avg. ISS 25.2).
