Strategies of hemopoietic stress adaptation within the medullary cavity
The Anatomical Record, 1986AbstractGravimetric determination of total bone water space was used as an index of available bone marrow space in mice following various specific stressors, i.e., splenectomy, hypoxia, bone fracture, and estrone‐induced osteosclerosis. Data was corrected for bone weight and was reported as specific bone marrow volume (total bone water space/mg dry ...

Atypical medullary carcinoma of the breast metastatic to the oral cavity
American Journal of Otolaryngology, 1994Breast cancer presently accounts for 27% of cancer diagnoses in women.’ It has been only since 1985 that breast carcinoma has been supplanted by lung carcinoma as a cause for cancer death in w0men.l Treatment of locoregional breast carcinoma generally consists of surgical resection and, depending on the initial stage of disease, adjuvant chemotherapy ...

Robotized access to the medullary cavity for intramedullary nailing of the femur
Technology and Health Care, 2010Introduction: The insertion site for an antegrade femoral intramedullary nail in the treatment of a femoral shaft fracture has traditionally been performed using a free-hand technique. An inappropriate starting point can result in suboptimal nail insertion leading to malreduction, or iatrogenic fracture.

Expansion of the medullary cavity at the expense of cortex in postmenopausal osteoporosis
Metabolic Bone Disease and Related Research, 1984Transilial biopsies from postmenopausal osteoporotic patients showed that static features and remodeling activity tended to form a pattern, with the area midway between the cortices having less bone and lower remodeling activity than the area closer to the inner boundary of the cortex.

The physics of heat generation during reaming of the medullary cavity
Injury, 1998Clinical experience of special cases of reaming of a small diameter medullary cavity has shown a remarkable temperature increase with associated thermal damage to the surrounding tissue. By applying known solutions of the heat conductivity equation to simplified models of a reamer to bone tube system, the effects of the most important parameters on ...

Injury, 1993
The reaming process is considered the main damage factor in intramedullary nailing, as there are repeated increases in intramedullary pressure and cortical temperature, which can lead to aseptic cortex necroses and fat embolisms. In this study, the influence of the compression force on the increase in pressure is to be examined.

Mechanical effects of reaming and implantation of acrylic cement into the medullary cavity of bones
Archives of Orthopaedic and Traumatic Surgery, 1984Changes in the mechanical properties of the rat femur caused by intramedullary application of bone cement were studied. In one group of animals reaming of the medullary cavity was performed, and bone cement was injected. In a control group only reaming was performed.

Successful intraosseous infusion in the critically ill patient does not require a medullary cavity
Resuscitation, 2003To demonstrate that successful intraosseous infusion in critically ill patients does not require bone that contains a medullary cavity.Infusion of methyl green dye via standard intraosseous needles into bones without medullary cavity-in this case calcaneus and radial styloid-in cadaveric specimens.University department of anatomy.Two adult cadaveric ...

Effect of curettage of the medullary cavity on bone marrow stromal precursor cells
Bulletin of Experimental Biology and Medicine, 1978Changes in the number of stromal bone marrow precursor cells in guinea pigs after curettage of the medullary cavity were studied by cloning and monolayer cultures in vitro. Curettage was shown to remove about half of the fibroblast colony forming cells (FCFC) from the bone marrow.

Periosteal and Intraosseous arteries of the human femur: Sphincter‐arteries in the medullary cavity
Clinical Anatomy, 1993AbstractMicroanatomic injection and corrosion casts were made of 30 human femora of all ages to study the distribution of periosteal and intraosseous arteries; additionally, the marrow of 85 femora (also from all ages) was harvested for histological examination of these vessels. Examination of the diaphyseal and metaphyseal periosteal arteries revealed
