[A comparative study of the course of aged patients with hip surgery].

On an orthopedic surgical unit we studied the course of patients aged over 70 years who had undergone surgical operation on the hip in 1974 and 1975. Distinguishing the pre-opérative, per-operative and post-operative stages, we used firstly, the distribution according to age and sex, the past history, the laboratory findings, the type of operation and the type of anesthetic. Then, we carried out a comparative analysis in relation to the past history, the post-operative complications and the deaths.
