Between 1973 and 1980 the authors inserted 100 large prostheses of the upper end of the femur. The first seven were used for intertrochanteric fractures but a high rate of complication was encountered and the method abandoned. Of the remaining prostheses 50 were used following resection of the upper end of the femur for metastatic or primary tumours and the remainder for revision of previous hip arthroplasties. Relief of pain was universal and a satisfactory functional result was obtained in two thirds of the patients. No loosening of the cup was encountered.
This paper investigates the incidence of infection following Kuntscher intramedullary nailing of 1059 open or closed fractures treated between January 1967 and December 1980. The fractures comprised 503 of the tibia 440 of the femur and 116 of the humerus. The literature over the past 10 years demonstrates that infection following plating or nailing with open reduction is more frequent than after closed intramedullary nailing. This paper confirms that nailing with open reduction for tibial and femoral fractures increases the infection rate to 5.7% and 3.5% respectively. Closed intramedullary nailing by Kuntscher's method is considered to be sound treatment in a university service for the treatment of fractures of the shaft of the tibia, femur and humerus with an infection rate of less than 1% in closed fractures.

Data from a series of 45 internal fixations for malignant secondary tumors of the humerus are analyzed. The tumors occurred late in the evolution of the cancer, and represented 24% of appendicular bone metastases for which operations were performed. Statistics of the patients, fractures, treatment, and results are presented and conclusions drawn. Prognosis should be related to the types of primary tumor. Blind nailing or pinning is recommended, and indications for preventive osteosynthesis are discussed.

477 cases of femoral head arthroplasty for fresh femoral neck fractures were reviewed to study the various factors modifying life prognosis during the first six months (age, associated disorders, type of prothesis, postoperative complications). Certain of these factors were found to affect prognosis unfavorably: bad general health, alcoholism, psychiatric or neoplasic disease, diabetes, and also, to a less degree, senility, neurologic and sensorial disturbances, cardiac deficiency. A rate table makes it possible to make a prognosis on the basis of these different factors.
Ender's closed nailing was initially described for osteosynthesis of trochanteric fractures in elderly people. The authors performed about 500 cases, advanced their indications, and applied this technic to two particular types of lesions, segmental fractures of the femur including the neck and shaft, and metastatic fractures of upper femur. They discuss their indications, technical problems and results.

The authors treated 74 humeral shaft fractures with "hanging cast" technique. They study the benefits and difficulties of the method, compared to other orthopaedic and surgical possibilities. Stiffness of the shoulder represent the most important part of 12% bad results. There are only 3% pseudarthrosis. It is a simple and safe treatment, with appliance to most humeral shaft fractures in cooperant patients.
The authors analyse a series of 70 bimalleolar fractures treated surgically with a follow up of 3 to 8 years. The late functional and radiological result was favourable in 85.7% of cases. They were able to determine from this series a certain number of unfavourable factors on which surgery has a better influence than immobilisation: e.g. fractures with a large displacement, impaction of the roof of the mortar, open fractures. Complications were rare; in 50% they were the result of technical errors avoidable with experience. The indications are noted; the authors consider that certain fracture should be operated straight away, that others should not be operated on, and that finally, an intermediate group should first be treated by immobilisation.
The authors present a series of 18 femoral and humeral metastases of bronchial origin treated by surgery. They study the results and recommend "closed wound" osteosynthesis, underlying the antalgic character of the intervention which does not modify the already limited survival.
Present-day techniques used in the surgical treatment of bony metastases of the limbs are described in relation to a series of 116 cases. Emphasis is laid on the possibilities of osteosynthesis or preventive arthroplasty.

The authors advocate the technique of blind medullary nailing with reaming of the medullary canal followed by a several weeks-traction in the treatment of compound fractures of the femoral shaft. This method is specially indicated in bursts of the bone, when no stability can be obtained after osteosynthesis and was used in 44 cases. In the same time blind nailing without traction was applied to 272 cases. The results were: sepsis: 0; non-unions: 0; malunions: 5; stiff knees: 3.
