Does [ Application of modular cementless femoral stem in complex revision hip arthroplasty ]?
The application of modular cementless femoral stems (LINK MP modular stem) in complex revision hip arthroplasty (especially in cases with the serious defect of proximal femoral bone) shows good results at both the short-term and long-term follow-up, especially in the revision for prosthetic infection with the high success rate. In order to avoid complications and improve clinical outcomes,the surgeons should carefully select proper surgery candidates,perform the procedure with care, and master the key surgical techniques.
IL-1β and tumor necrosis factor (TNF)-α are key mediators of inflammation in IRI. Although difficult to measure because of short half-lives, their downstream effectors indicate their levels of activity. IL-1 receptor antagonist is secreted in response to IL-1β, and monocyte chemotactic protein in response to TNF-α. Their decreased production over the course of HMP suggests that interruption of acute-phase inflammation in the graft may attenuate reperfusion-related graft injury. Further cDNA studies and effluent analyses are required to confirm this hypothesis.
