Predictors of the need for total hip replacement in patients with osteoarthritis of the hip.

Rationale: the natural history and risk factors for hip osteoarthritis are still unknown.

Objective: to identify factors predicting a need for total hip replacement at some time during the course of hip osteoarthritis.

Patients And Methods: outpatients evaluated between 1981 and 1986 for hip osteoarthritis were studied retrospectively.

[Physiology of tendon and physiopathology of tendinitis].

Despite the histological knowledge acquired from light and electron microscopy and the deeper studies devoted to the composition of tendons, we are still unable to draw practical conclusions concerning the treatment of tendinitis. Experimental in vivo studies and biochemical studies are still too far from physiological conditions to be useful in the traumatology of tendons. They have, however, the merit to provide better theoretical basis and to persuade doctors specialized in sport not to disregard these date.
