Biphasic synthetic bone substitute use in orthopaedic and trauma surgery: clinical, radiological and histological results.

Searching for an alternative to bone grafts in orthopedic and trauma surgery, two biphasic synthetic calcium phosphate ceramics BCP are made: the first, Eurocer 400, in granule form with a high interconnected porosity for void-filling, and the second, Eurocer 200, available in different shapes, with a good mechanical resistance in compression. Two hundred cases are reported with more than a six-month follow-up. The first 72 cases relating to hip arthroplasty revision surgery (29 involving acetabular and 43 femoral stem loosening) are exposed with some technical details.

Surgical treatment of malignant secondary tumors of the humerus: report of 45 cases.

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.

[Femoral neck fracture treated by head arthroplasty: factors of life prognosis. 477 cases (author's transl)].

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.

[Surgery of bimalleolar fractures. Results of a series of 70 cases with a follow up of 3 to 8 years (author's transl)].

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.
