What is a hip ?

Hip is a weightbearing joint that connects the femur to the pelvis providing freedom of movement. Bone surfaces of head of femur and the pelvis acetabular cavity are covered with cartilage that act as a cushion and allows movement. In hip pathologies, this cartilage and sometimes the underlying bone lose their cushioning properties and their sphericity. This phenomenon is called arthrosis.

What is arthrosis ?

Chronic joint damage characterized by an initial destruction (“wearing”) of joint cartilage. Arthrosis can be primitive (without any precise cause) or secondary to a joint deformation resulting from a malformation (congenital disorders) or an acquired deformity (after an accident, for example).
Hip (osteoarthritis of the hip) and knee degeneration (gonarthrosis) are the most common disorders and can be potential responsible of an aggravated disability or handicap when arthrosis complicates a preexisting motricity disorder.

Treatments available ?


  • Medical treatments (antalgics, anti-inflammatories, reeducation, infiltration).
  • Surgical treatments (knee prosthesis).


What is a total hip prosthesis ?

Total hip prosthesis is an operation to replace only both hip joint surfaces. An ablation of femoral head and femoral neck is performed. Femur is prepared to receive a shaft. Joint surface of the pelvis is also replaced by a metallic implant directly anchored in the bone.
Total hip prosthesis comprises 4 components :

  1. A metallic cup anchored in hip bone,
  2. An insert (metal, ceramic or polyethylene) placed in the cup
  3. A head (ceramic or metal) placed on a shaft
  4. A femoral stem
