Robotized access to the medullary cavity for intramedullary nailing of the femur
Technology and Health Care, 2010The 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.

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 ...

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.

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 ...

Geometric Analysis of the Proximal Medullary Cavity of the Femur in the German Shepherd Dog [PDF]
Veterinary and Comparative Orthopaedics and Traumatology, 1998 SummaryForty-one cadaver femora of German Shepherd dogs were prepared for implantation of a cementless total hip prosthesis by reaming of the proximal medullary cavity with standard orthopaedic instruments. Silicone paste imprints of the cavity were taken and measured with a 3 D laser reflection system.

A morphometrical study of the medullary cavity of the ulna referred to intramedullary nailing
Surgical and Radiologic Anatomy, 2006Intramedullary fixation is preferred for osteosynthesis in the case of long bone fractures; but the problem of the nails' adjustment to the anatomical needs remains. About 80 cadaveric ulnae were examined to elucidate the curvature of the medullary cavity, the point of varus angulation, the thickness of the radial and ulnar cortical bone and the ...

Renal medullary carcinoma involving serous cavity fluids: a cytomorphologic study of 12 cases
Journal of the American Society of Cytopathology, 2021Renal medullary carcinoma (RMC) is a highly lethal adenocarcinoma with a propensity for widespread metastatic disease in young patients. It is strongly associated with sickle cell trait and shows the loss of SMARCB1 (also known as INI1 or BAF47) protein expression.

Effect of medullary cavity in cancellous bone on two-wave phenomenon
Japanese Journal of Applied Physics, 2016Abstract Osteoporotic patients have a larger medullary cavity in their cancellous bone than healthy people. In this study, the effect of the medullary cavity on the two-wave phenomenon was experimentally investigated using a cancellous bone model and a radius bone model.

The Journal of Bone & Joint Surgery, 1970
A study was made of the extent of the intracortical vascular damage occurring on intramedullary reaming in the rabbit tibia with simultaneous reduction of pressure in the distal part of the medullary cavity, and the findings were compared with previously reported results from rabbits in which reaming was performed without such pressure reduction.

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.
