Is Cancer The Price We Pay For Being Smarter Than Chimps?
Are the cognitively superior brains of humans, in part, responsible for our higher rates of cancer? That"s a question that has nagged at John McDonald, chair of Georgia Tech"s School of Biology and chief research scientist at the Ovarian Cancer Institute, for a while. Now, after an initial study, it seems that McDonald is on to something. The new study is available online in the journal Medical Hypothesis and will appear in the forthcoming issue of the journal.

Navigation In Hip Resurfacing

Hip resurfacing can be a good alternative to total hip replacement (THR) in young adults because it conserves bone and it has acceptable short- to medium-term results. However, there have been concerns about fractures of the femoral neck with this procedure, partly due to notching and varus alignment during implantation. Therefore, in this study the author"s used imageless computer navigation as a method to aid in the placement of the femoral component in hip resurfacings. Pre-operative templating was used to determine the planned stem-shaft angle against the native neck-shaft angle. Post-operatively, this template was then assessed using digital anteroposterior unilateral radiographs of the hip. There were no instances of notching of the femoral neck or varus alignment of the implant. The stem-shaft angle differed from that planned by 2.8° and while "a learning curve was observed in the time taken for navigation" this was not true for accurate placement of the implant." The author"s conclude that "computer navigation for placement of the initial guidewire in hip resurfacing has been shown to be more accurate than the use of conventional mechanical jigs" and that it "shows promise in optimising the preparation of the femoral head" and in helping to reduce factors that can cause the femoral neck to fracture and the implant to fail.
