SCP and St.Olavs Hospital, Trondheim University Hospital has based the development and introduction of a new implant on the philosophy of Malchau among others with:
• experimental studies
• clinical studies
• randomized multicenter studies
From the beginning, SCP has considered experimental studies for the understanding and documentation of the implant as very important. SCP has in cooperation with Trondheim University Hospital, established a biomechanical laboratory where these studies can be carried out.
A hip simulator is used to create test conditions reconstructing physical loads on the femur during normal gait and stair climbing. It is then possible to measure responses in the bone dependent on the load configurations and design of the implant.
This experimental work is important for the optimization of the design criteria for the customized implant. SCP and Trondheim University Hospital have carried out several experimental studies in this laboratory to evaluate the different aspects of designing hip implants. The most important factors for experimental investigations are stability of implant and load transfer from prosthesis to bone.
SCP and Trondheim University Hospital have carried out a number of studies related to the development of a custom hip prosthesis.
These studies include:
• stability studies in hip simulator
• strain and deformation studies in hip simulator
• in vivo strain measurements
• bone density studies (CT)
• investigations of medial offset of the hip
• investigations of anteversion angle of the hip
• studies on results of pre operative planning of
total hip replacement
