The needle-palisade fixation for total resurfacing arthroplasties of hip and other joints (e.g. knee joint) and the implantation method are presented. The needles are symmetrically spaced on the terminal surfaces of the endoprothesis up to a resistance edge on one portion of the endoprothesis and up to a resistance surface on a second portion of the endoprothesis. The area between multilateral needles will be filled up by new bone formation to the terminal surfaces. The endoprothesis also includes a glenoid cavity and a head which have round terminal surfaces with the multilateral needles placed. The projected multilateral needles have different lengths and mutually parallel axes which are perpendicular to the planes in which the round resistance edge of the glenoid cavity and resistance plane of the head are located. Each of needles is pyramidal. The total surface area of the needle-palisade fixation system is at least seven times greater than total surface area of head external surface and it is when the relation between radius and height of pyramid is about 1 to 5. The implantation method involves the successive introduction of multilateral needles into the spongy bone. The concept of the needle-palisade system for total hip replacement fixation presents: 1) safer operative procedure-press-fit technique, 2) easier revision arthroplasty, 3) good adhesion system (important for example in case of osteoporosis), 4) cortical and cancellous load transmission system, 5) "biological-like" fixation, expectable "life performance" solution, 6) uniform distribution of biomechanical forces. The geometrical model of the new concept of the endoprosthesis for total hip resurfacing arthroplasty created in Autodesk Inventor CAD system is presented. The model is assigned for further experimental researches, i.e.: FEM analysis, virtual simulation of endoprosthesis insertion and the productions of prototypes for biomechanical experiments and pre-clinical investigations.
