We hypothesized that bone resorption acts to increase bone strength through stimulation of periosteal expansion. Hence, we examined whether bone resorption, as reflected by serum β-C-telopeptides of type I collagen (CTX), is positively associated with periosteal circumference (PC), in contrast to inverse associations with parameters related to bone remodeling such as cortical bone mineral densi...
The hair was immediately removed from the neighbourhood of the wound, and as it was matted with blood the whole scalp was subsequently shaved, when also a contused wound was found to exist over the parietal bone of the same side'. A bluut probe was carefully introduced and gently pressed against the cut edges of the bone, but no broken portions were felt, so I did not consider it justifiable to...
The intramedullary alignment guides used in total knee replacement disrupt the intramedullary vessels, resulting in greater postoperative blood loss. The use of an autologous bone plug to seal the intramedullary femoral canal has been shown to be effective in reducing postoperative bleeding. The authors present a simple technique to create a bone plug from the anterior chamfer femoral cut to pe...
-stress fractures with surrounding bone marrow edema are most commonly seen in the medial femoral condyle and medial tibia secondary to radial or complex tears of the medial meniscus; the bone cut off from its blood supply by the subchondral fracture is at risk to develop osteonecrosis, therefore a follow-up MRI is typically useful in this setting to ensure fracture healing and exclude the deve...
The use of lasers has become increasingly common in the field Background of medicine and dentistry, and there is a growing need for a deeper understanding of the procedure and its effects on tissue. The aim of this study was to compare the erbium-doped yttrium aluminium garnet (Er:YAG) laser and conventional drilling techniques, by observing the effects on trabecular bone microarchitecture and ...
Background: The use of lasers has become increasingly common in the field of medicine and dentistry, and there is a growing need for a deeper understanding of the procedure and its effects on tissue. The aim of this study was to compare the erbium-doped yttrium aluminium garnet (Er:YAG) laser and conventional drilling techniques, by observing the effects on trabecular bone microarchitecture and...
Microfocus computed tomography (micro-CT; R_mCT) is a dynamic noninvasive method for measuring bone regeneration. This study evaluated whether R_mCT was equivalent to histomorphometry in assessing bone augmentation. Two plastic caps of graft material with (experiment) or without hydroxyapatite (HA; control) were placed in the exposed calvaria of rats. Images of bone augmentation within the plas...

Aim of study was determine if a correlation exists between bone mass density and concentration of osteoprotegerin. We examined the group of 199 patients of mean age of 63 years. Of the group under study, 31 patients had normal bone density (T score > -1 and < 1) and 168 probands had osteopenia or osteoporosis (T < -1). Persons with normal BMD values had median values of OPG 60.8 ng/l, while pat...
