MUTARS femoral stem cemented TiN with HA collar - Uncoated femoral stem prosthesis, modular

Intended purpose

A femoral Stem used in cases of major bone loss to support a hip, knee or diaphysis replacement prosthesis and provide primary fixation to the bone. Primary indication for the use of the MUTARS systems is after bone resection because of a tumour. Further indications for the use of the MUTARS systems are massive bone loss such as in Morbus Gorham or for the revision arthroplasty and for the prosthetic treatment in case of fractures, pseudarthrosis and arthrosis..

Functional description

Composed of CoCrMo with HA (hydroxyapatite) coating of the collar with locking holes for diameter 4.5mm screws. The stems have a hexagonal cross section which provide for an optimal intramedullary fixation. In the femoral area, the stem was designed to correspond with the physiological antecurvation of the femur. Hexagonal rasps are used to achieve a primary stability of 70 Nm. The stem is to be implanted with bone cement.
