Nationwide study on the risk of unprovoked venous thromboembolism in non-traumatic osteonecrosis of femoral head
AbstractPurposeEndothelial dysfunction is a risk factor for osteonecrosis of femoral head (ONFH) and venous thromboembolism (VTE) [defined as deep venous thrombosis (DVT) or pulmonary embolism (PE)]. However, the risk of unprovoked VTE in non-traumatic ONFH patients remains unclear.MethodsWe investigated the relationship between ONFH and VTE using Taiwan National Health Insurance Research Database (NHIRD). Between 1997 and 2010, a total of 1514 non-traumatic ONFH patients were identified from 1,000,000 general populations after excluding initially concomitant diagnoses of DVT and PE, and subjects undergoing lower limb surg...

AbstractBackgroundFunction after revision total hip arthroplasty (THA) in failed metal-on-metal (MoM) hip resurfacing arthroplasty (HRA) is variable, but post-operative complication rates are reportedly high. We hypothesized HRA conversion to THA using the direct anterior approach (DAA) would be associated with optimal outcome.MethodsSeventeen MoM-HRAs in 15 patients (seven males, eight females) were revised through the DAA. The mean age was 45  years (28–59 yrs). The most common indications for revision were aseptic loosening of the acetabular component or of the femoral component and femoral neck fracture...

Vitamin D: part I; from plankton and calcified skeletons (500 million years ago) to rickets
AbstractThe vitamin D history started early in the evolution of life (billion years ago) as a photochemical reaction producing an inert molecule. During the early evolution of vertebrates, this molecule became essential for calcium and bone homeostasis of terrestrial animals and arrived to the status of hormone. Phytoplankton, zooplankton, and most plants and animals that are exposed to sunlight have the capacity to make vitamin D. Vitamin D is critically important for the development, growth, and maintenance of a healthy skeleton from birth until death. The major function of vitamin D is to maintain calcium homeostasis. I...

Higher prevalence of periprosthetic fractures with ceramic on polyethylene hip bearing compared with ceramic on ceramic on the contralateral side: a forty  year experience with hip osteonecrosis
AbstractPurposeIt is unclear whether late THA periprosthetic femoral fractures are related to a mechanical mechanism that decreases strength of the femur (for example, loosening) or to a biological problem as osteolysis. It is also unknown if ceramic on ceramic bearing couples decrease the risk of late periprosthetic fractures as a result of the absence of wear and osteolysis.Material and methodsWe therefore asked whether the cumulative long-term fractures were different according to the couple of friction ceramic on ceramic or ceramic on polyethylene in 327 patients (654 hips) with bilateral THA (one ceramic-ceramic, and ...
