Combined shortening and rotational osteotomy with Unique® femoral stem
Our core competencies in computer assisted design enable us to offer competitive prices and a high degree of support to orthopaedic surgeons in this field. All components are individually designed by our experienced and highly dedicated team of technical engineers in accordance with your specifications or requirements, and we provide proposals for solutions to your challenges.
As in the case of prostheses for THA, the basis for our design process is CT-images in order to obtain optimal intramedullary fixation. The design of extra-medulary parts will be made according to specifications provided form the orthopaedic surgeon in each case.
Condyles for attachment of external prostheses
Traditionally, external prostheses have been attached by means of a holster (socket) with straps. In the case of humerus amputees, these straps have been around the shoulder and neck. This has in turn caused muscle problems and discomfort for the patient. Due to a soft and uneven end of the residual limb, good fixation of an external prosthesis may in addition represent a challenge.
In cooperation with St. Olavs University Hospital in Trondheim, and the leading, international company Otto Bock AG, Germany, we have developed a fixation condyle which is anchored within the canal of the residual bone (Fig. 1). There is no longer need for fixation straps, and the patient is ensured good fixation of the holster.
Our technology in this field can be applied for humerus as well as femoral amputees (Fig. 2), and offers the additional advantage of improved load distribution both with and without the use of an external prosthesis.

Individually designed tumour prostheses
Our technology may as well be applied for the design and manufacturing of individually designed oncology prostheses. Again, we are able to adapt fully to the needs and the instructions of the orthopaedic surgeon designing and manufacturing the whole prosthesis, or extensions to standard implants to make them fit to the patient (Fig. 3).

Fig. 3 Shoulder tumour. The proximal part of the humerus was resected due to a tumour. The resected part was
replaced with a special implant which was designed for intramedullar fixation in the
distal part and attached to Delta Reverse Acetabular Component (DePuy) in the proximal end.

Fig 4. Radius tumour. The distal part of the radius was prior to implant surgery resected and replaced with a spacer
of bone cement. In collaboration with the surgeon a titanium implant with dual-layer coated IM part with a optimal diameter and an external part
adjusted to reconstruct the resected segment attached to Metacarpal 2 and 3 was designed.

Combined shortening and rotation osteotomies
In cases with extreme anteversion in combination with leg length differences, we offer the Unique femoral stem individually designed for a combined rotation and shortening osteotomies. In our design process we take account of the planned resection level, offering a stem with an excellent cementless fixation, also in these cases. The stem will also function as an IM-nail for rigid fixation of the proximal and distal part of the femur after the resection.

Unique femoral stem for revision surgery of primary THA
SCP is in the process of testing out our technology also in revision surgery, and the first successful procedures have been performed at the St. Olavs Hospital in Trondheim. We are at this stage searching for orthopaedic surgeons interested in taking part in development of a new product based on our technology.
