[Prevention of heterotopic ossification following prosthetic total hip replacement].

Heterotopic ossification, mostly of the hip, is a frequent complication after reconstructive surgery. Most common prophylactic therapies are non-steroidal anti-inflammatory medication (AINS) applied post-operatively and external radiotherapy (RT) administered in the pre- or post-operative setting. Both treatments proved to be efficient in several randomised clinical trials. Prevailing trend regarding RT is a treatment prior to surgery. It is appreciated by both physician and the patient because it is simple and comfortable. In this article, we present the literature linked to the subject together with the benefit and the inconvenience of both therapeutic methods.
