[X-ray computed tomography in the study of fractures of the calcaneus].

In a series of 28 calcaneal fractures, computed tomography scanning has shown axial deformities in the coronal and horizontal (plantar) planes not previously recognized. Two-thirds of the fractures investigated showed a deformity in at least two planes. A combination of dorsiflexion, valgus and adduction was present in one-third of the cases. This examination allowed a precise measure to be made of the enlargement of the calcaneus which very frequently occurs and was greater than 25 per cent in two-thirds of the cases. It makes it possible to visualize subtalar and calcaneocuboid incongruence with great precision and, in particular, to determine the size of the incongruous surface and its severity. Computed tomography scanning showed the existence of subtalar incongruity without depression of the thalamus, which is a concept which is not well recognized. It shows incongruity which is not evident on normal radiographs or, conversely, which may be falsely interpreted from deceptive pictures. The results of this study indicate that the usual classifications based on radiological examination are inadequate and need to be revised. The accuracy of this examination leads to the hope of more precise indications for treatment in the future.

[Mixed fractures of the posterior wall of the acetabulum. Value of x-ray computed tomography].

The authors have studied three cases of fracture of the posterior wall of the acetabulum in which one fragment was separated and another was impacted. The nature of the lesions were not able to be appreciated on standard radiographs but was visualised by means of tomodensitometric studies. The patients were treated surgically to obtain an accurate reconstruction of the articular surface. The importance of tomodensitometry in the diagnosis of such lesions is stressed.

[A case of bone lipoma of the femur head].

A case of intra-osseous lipoma of the upper femur is reported. A review of the literature shows that this lesion is rare, only about 33 cases having been published. The radiological appearance is that of a fibroma. The diagnosis is made at the time of surgery which reveals the presence of fat in a large cavity. Curettage and bone graft resulted in healing.

[Treatment of recurrent luxation of total hip prosthesis by posterior methyl methacrylate buttress].

A shelf operation using cement held by screws inserted into the posterior wall of the acetabulum is described in cases of recurrent dislocation of hip prostheses. The procedure was used in 7 cases of total prostheses and 2 of femoral prostheses. The technique is simple and reliable. It should be used when there is no obvious malposition of the prosthesis or in the elderly when a further operation to re-orientate a faulty prosthesis would be too risky. The results were satisfactory with 7 successes in 9 patients.

[Treatment of bimalleolar fractures by centromedullary nailing of the fibula].

An osteosynthesis technique involving nailing of the fibula was used to treat 106 bimalleolar fractures. Details of the technique used are described and results analyzed with respect to clinical course and radiologic findings. A generally favorable outcome was obtained. Nailing of the fibula provides a solid foundation, particularly in low and comminuted fractures.
