A common situation presenting to the orthopaedic surgeon today is a worn acetabular liner with substantial acetabular and pelvic osteolysis. The surgeon has many options for dealing with osteolytic defects. These include allograft, calcium based substitutes, demineralised bone matrix, or combinations of these options with or without addition of platelet rich plasma. To date there are no clinical studies to determine the efficacy of using bone-stimulating materials in osteolytic defects at the time of revision surgery and there are surprisingly few studies demonstrating the clinical efficacy of these treatment options. Even when radiographs appear to demonstrate incorporation of graft material CT studies have shown that incorporation is incomplete. The surgeon, in choosing a graft material for a surgical procedure must take into account the efficacy, safety, cost and convenience of that material.
Volume 4 -Issue 3 suggested a cephalomedullary device because they have determined improved walking ability [16] and tend to offer a shorter recovery [17]. However, there was some mechanical failure from Proximal Femoral Nail Anti-rotation (PFNA) blade cut-out in clinical practice after osteoporotic hip fracture fixation because of discontinuity of principal tensile trabeculae (lack of bone trabeculae to prevent blade cut-out). A few literatures have identified potential of Polymethylmethacrylate (PMMA) cement-augmented helical PFNA blades to improve implant stability only in human cadaveric study [18,19]. Moreover, they lack data demonstrating PFNA with cement augmented blade in clinical study. Therefore, purpose of our study was to undergo the preliminary study whether PFNA with cement augmented blade reduces the
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
