[Uncommon surgical treatment of a tibial fibrous bone dysplasia].

The authors present an original method of treatment in prevention of fracture of the tibial shaft applied in one case of polyostosic fibrous dysplasia of bone. They treated this localization by closed intramedullary reaming and stuffage with cancellous bone grafts.

[Bone metastases of breast cancer. Surgical treatment of 228 sites in the limbs].

A series of 228 bone metastases of breast cancer in the limbs was operated continuously in the same division from 1965 to 1989. The consistent analysis of epidemiology, techniques and results allowed regularly improving the accuracy of surgical indications, which are now properly codified and preferably include arthroplasties and closed-focus osteosynthesis.

[Ender's so-called alignment nailing in the treatment of trochanteric fractures in the young adult, and under certain circumstances: is it reasonable? Study of a series of 50 cases].

The technique and results of an original method of "alignment Ender's nailing", combining standard Ender's nailing with post-operative traction is described. This method is directed towards young patients in two well-defined situations: the complexity of the trochanteric fracture and the debilitation of the patient. A consecutive series of 50 cases have been analysed. There were no infections and no technical failures. A detailed study of hip and knee function and of the anatomical reconstruction in both antero-posterior and lateral planes with a mean follow-up of 20 months has shown 82.6 per cent of good and very good results.

[Resection-reconstruction of the femur shaft by a massive allograft fixed by an interlocking nail].

Case report of a central midshaft osteosarcoma of the femur, treated conservatively under Rosen procedure. Bone resection was followed by reconstruction with a deep frozen (-196 degrees) conserved massive homograft, fixed by an interlocked Kuntscher's nail. The purpose of this paper is to expose the advantages of this type of fixation, V.S. conventional nails, or plates. X-Ray showed a bridging bone spindle between host and graft cortical bone, induced by initial stability of the nail, and a rapid fusion after secondary dynamisation of the nail, by removing one screw. We obtained an early functional recovery and a complete and rapid autonomy necessary to allow social and school reinsertion, whatever should the medium or long term presumed survival be.

[10-year follow-up of a homogeneous series of 467 total hip prostheses of the Charnley-Müller type. Study of 167 cases].

Four hundred and sixty-seven hips were operated upon by the authors between 1969 and 1974 using the Charnley-Müller prosthesis. 167 were reviewed with more than a ten-year follow-up. Eighty-one per cent were satisfactory after the initial procedure. In 56 cases an aseptic loosening had to be revised. At the femoral level, a varus position of the stem and the presence of cement between the calcar and the prosthesis appeared to be the responsible factors. At the acetabular level the causes of the loosening were an excess of cement, more than 10p. 100 uncovering of the cup by the acetabulum and, particularly, asymmetrical wear of the cup of more than one mm. A pathological study of 20 cases showed that particles of cement cause granulomata to develop all round the prosthesis. Polyethylene wear increases the frictional torque and produces micro-fractures of the cement at the bone-cement interface. It is concluded that the femoral stem should be as thick as possible and that the collar of the prosthesis is useless. Frictional torque should be as low as possible. The use of a metal mesh appears to be beneficial for the cementing of the acetabular cup.

[Twenty-year record of osteosynthesis of bone metastases. Analyses of 300 cases].

The authors have analysed the results of 300 operations for metastases in bone carried out in the last 20 years. The best results were obtained where prosthetic replacement was possible, and where deposits in long bones were treated by closed intramedullary fixation. This type of surgery gives satisfactory, comfortable function and should be part of a multidisciplinary approach in the management of patients with cancer.

[Nailing for alignment combined with the Sarmiento method. An interesting combination in the treatment of unstable diaphyseal fractures of the tibia].

The authors have reviewed 51 cases of unstable fracture of the tibia treated by nailing followed 3 weeks later by bracing using the Sarmiento technique. The results confirmed the basis of Kuntscher nailing with reaming. This combination of two techniques can rival more sophisticated techniques such as locked nailing. Several complications were noted - one sepsis, one non-union, two malunions and one shortening of 2 cms.

[The risk non-union following closed-focus nailing and reaming. Results of 1059 interventions using the Kunstcher method].

The authors have studied a series of 1059 compound and closed fractures of the diaphysis of long bones treated by intramedullary nailing according to the technique of Kuntscher, to assess the incidence of non-union. Between January 1st 1967 and December 31st 1980, 503 fractures of the tibia, 440 of the femur and 116 of the humerus were so treated in both adolescents and adults. The fractures were mostly sustained in road traffic accidents. The risk of aseptic non-union was small, but occurred more readily when the skin was damaged and when the site of the fracture was at the junction of the lower two quarters of the tibia; the incidence was highest when the technique of nailing was incorrect or when the going was undertaken too late. The incidence of non-union and infection are compared with those of other series using the same closed technique and with reports describing insertion of the nail of the plate by opening the fracture. It is concluded that intramedullary nailing using the Kuntscher technique is the most reliable treatment for this type of injury for routine use in an acute fracture service. In this series the incidence of aseptic non-union was approximately 1%, of infection with non-union less than 0.5% and of early infection with eventual union less than 1.5%.

[Complications observed in a series of 2018 total hip replacement (author's transl)].

Complications occurred in 220 out of 2018 total hip replacement operations (10.9%) and were responsible for 35 post-operative deaths (1.73%). They included early vascular accidents (3.6%), post-operative dislocations (2.47%) and late aseptic prosthesis loosening (3%). Sepsis was uncommon (1.28%). Other complications were exceptional and unforeseable.

[Screwed-plate osteosynthesis and reconstruction of fractures of the calcaneus].

The authors have treated 182 fractures of the calcaneus. Ninety-nine of these were operated on and plated. The results were studied in 75 cases with a follow up of 1 to 6 years. The technique used a lateral approach; a plate was always used, sometimes with a heterogeneous bone graft (Kiel bone). The operation was followed by 3 weeks of plaster cast fixation followed by mobilisation of the foot. A good functional result was obtained in 82 p. 100 of cases, but a satisfactory anatomical reduction in only 73 p. 100. Some mobility of the subtalar joint was conserved in 73 p. 100 of cases. The indications are described. This type of operation should be performed in displaced fractures with 2, 3 or 4 fragments. In more comminuted fractures the authors consider that primary arthrodesis is advisable. Conservative treatment is indicated in slightly displaced fractures or when local conditions make operation inadvisable.
