Materials :
Cementless stems: titanium alloy and HAP
Femoral heads: “SI” made from stainless steel or “SD” made from Biolox® delta ceramic.
INSTRUMENTS
An unique instrumentation
A wide choice of broach handles for the different approaches : posterior, posterolateral, anterior and anterolateral.
INDICATIONS
The Libra® stem range is indicated in the following cases:
Primary or secondary arthrosis
Fractures of the proximal femur
Revision of a previous surgery, including hip arthroplasty
For revision of surgery other than hip arthroplasty, the implantation of the femoral stem must not interfere with the equipment that is not removed, if applicable
For hip arthroplasty revision surgery, the implanted femoral stem must be compatible with the equipment that has not been removed if applicable
Only for a cementless femoral stem implantation, these indications are appropriate according to the following classifications: type 1, 2A and 2B of the Paprosky classification.
