Indications

A hip replacement is indicated in those cases in which the quality of life of the patient has severely deteriorated. He/she feels pain that causes considerable disruption to everyday life. Faced with this serious problem, the patient will sooner or later decide to consult a doctor. Several different situations then present requiring the implantation of a hip prosthesis.

1. Simple prosthesis


The prosthesis is considered simple if the patient's anatomy is normal. The patient suffers from osteoarthritis, that is to say cartilage wear, but the anatomy of his/her pelvis and thighbone is normal. Moreover, he/she has not undergone a previous surgical operation on the hip or pelvis. This is the most frequent case.

2. Complex prosthesis


A hip prosthesis is considered complex if the patient's anatomy is not normal. This may be due either to a congenital deformity (dysplasia or congenital dislocation) or to a modification of the thighbone or pelvis during the patient's life (fracture, previous surgical operation).

3. Change (revision) of hip prosthesis

This surgical operation is often complex, the outcomes uncertain.. The surgeon needs to change (revise) the implants already fitted. The rate of complication is high. So, everything must be done during the first (primary) operation to avoid the need to re-operate.
