Unique® femoral stem
Unique is an individually designed femoral stem. Each prosthesis is designed in order to fit perfectly to the hip of the actual patient and to provide perfect biomechanics of the hip postoperatively. This ensures a long lasting artificial hip and high patient satisfaction.

Transversal CT-images from the patient’s femur and pelvis are used to facilitate the design of the Unique custom femoral stem. Individual design gives the possibility to fit the Unique femoral stem exactly to each patient, both intra- and extra-medullar. Precise adaptation to the patient morphology is achieved through the creation of a precise 3D digital model of the femur.

The intramedullary design, in accordance with SCP's design criteria, assures a close fit to endocortical bone in the proximal femur which guarantees both axial and rotational stability as well as proximal load transfer.


The design criteria provide an optimum mechanical primary stability and physiological loading which concurrently is a prerequisite for secondary long-term fixation of the Unique® stem.

Additionally, the Unique femoral stem reduces the need for correction osteotomies of the femur at THA (Total Hip Arthroplasty) since the prosthesis is both adapted to and is implantable into even the most distorted femoral canal.

By means of precise pre-operative planning it's possible to improve the post-operative biomechanics via optimization of the medial femoral head offset, correction of anteversion and equalizing leg-length.

The design principles enable the patient to regain or to increase the muscle strength and provide for a first-rate mobilization subsequent to THA.

The combination of intra- and extra-medullar design for the Unique femoral stem contributes significantly to a straight forward surgical procedure and a more predictable post-operative result of the hip reconstruction.

This product feature makes the Unique femoral stem especially suited for the subsequent diagnoses, which have indications for a primary THA.

   • Young and active patients requiring optimal hip function
   • Hip dysplasia
   • Juvenile rheumatoid arthritis
   • Avascular necrosis
   • Calvé-Legg-Perthes
   • Post traumatic situations

Excellent clinical data
According to data from The Norwegian Arthroplasty Register the Unique femoral stem shows excellent survival rate at both seven and ten years follow-up. The excellent clinical results have been obtained in despite of the fact that more than 50% of the Unique femoral stems included in the Register have been implanted into patients with secondary osteoarthrosis.

The Unique femoral stem is today regarded as a well documented femoral hip prosthesis which simplifies potentially complicated procedures of THA for patients with secondary osteoarthritis, easily reconstructs the biomechanics of the hip joint and contributes to a long life-time expectancy through optimum primary stability and physiological load transfer.
