The aim of the research on experimental parts was to analyse the influence of the lumbar stabilisation on the strength aspects of the lumbar part of human spine and stabiliser in case of spondylolisthesis treatment. The models were built with the use of pre-surgical CT diagnostics, routinely used in medical practice. MIMICS software was used to process the results of the neuroimaging research and to create a 3D model. Two models were built: one with and the other without a stabilizer. Afterwards, a static load analysis for the load coming from the upper part of the body was done. Analysis was performed using the finite element method (FEA). The performed simulations enabled to determine the stress in particular discs for both models, with and without transpedicular stabiliser.

“…Unfortunately, there are also contraindications for the procedure and these are: young age of the patient, infections of the joint and surrounding tissues, osteoporosis, extensive varicose veins, thromboembolism or very major limb deformation. Time returning to full efficiency after the surgery is usually a period of about 3 months [3][4][5].…”

The knee joint is the largest of all in the human body. It connects the femur, tibia and patella. It is a double-angled joint reinforced with ligaments and surrounded by a joint capsule. Because of the bandy leg or knock-knee, cartilage wear due to age or defective joint load, alloplastic surgery is required. This is a procedure planned individually for each patient depending on their age, gender or weight. To assess the scale of wear, knee cartilage was scanned using computed tomography. CT scans were processed into a 3D model using Materialize Mimics. Based on obtained bone models, a model of the endoprosthesis was designed using the Catia V5 software. Strength analysis was carried out based on the selection of appropriate materials and theoretically accepted loads.

“…A database of possible solutions is being created in the area of curing diseases and injuries of the spine. Applying methods of the rapid prototyping enables to design and to produce personalised endoprosthesis, in the form of the implant directly reflecting the injured vertebra [5,10]. As a result, doctors receive above action data enabling them to make a rational decision in relation to the considered case, requiring the treatment at an outpatients' clinic on the neurosurgical and orthopaedic branch.…”

Abstract. There is presented the possibility of using modern rapid prototyping methods in the form of reverse engineering on the example of lumbosacral spine of a human spine at the level of L3-L. Reverse engineering techniques were directly used in the generation and processing of point clouds from a real object. The point clouds were generated by using specialised Mimics software and basing on the results of computer tomography and magnetic resonance imaging using. In the next stage of processing, there was the export of the appropriately converted point clouds to STL format, compatible with CAD programs. The reverse engineering process took four steps: digitisation of the real object, using non-invasive imaging techniques (CT, MRI), processing the point clouds from the digitisation stage, construction of a surface model of the real object basing on the processed point clouds, realising of the real object's copy by using rapid prototyping techniques. In the final stage, the model of the complex spinal's part was tested to MES strength analysis.
