In the search for better long-term fixation, TM components have been introduced.
Uncemented or hybrid fixation of components was also more frequent in Denmark (22%) than in Norway (14%) and Sweden (2%).
We also identified proteins participating in the regulatory mechanism in nitrogen fixation, two components systems, transport and cell surface structure, energy transfer, cellular protection, and the transport and synthesis of polysaccharides.
Variables in the LROI database that were checked for validity were sex, date of birth, hospital patient number, encrypted personal identity number, diagnosis, ASA score, type of prosthesis, fixation, cemented component (in cases of hybrid fixation), product number of component and cement, type of revision, revised component, and conversion to THA or conversion to total knee arthroplasty (TKA).
There have been several efforts to improve stability of glenoid component fixation, including studies of glenoid component design [ 10, 11], glenoid component position [ 12], and screw fixation [ 13].
We used revision implants (Hintegra; Integra LifeSciences, Plainsboro, NJ) with a flat talar component with fixation pegs and tibial components of different thicknesses for appropriate reconstruction of the physiological joint line.
Secure fixation of acetabular components in total hip arthroplasty can be challenging.
Instruments are designed to allow cuts accurate enough for press-fit uncemented fixation of both components.
However, there has been some debate regarding fixation of humeral components, especially in total shoulder arthroplasty, because early prosthetic designs and surgical techniques showed inferior results when cementless humeral component fixation was used.
