Periosteal chondrosarcoma invading the medullary cavity
Skeletal Radiology, 1997We present a case of periosteal chondrosarcoma of the femur, in which a tumor invaded the medullary cavity and the lesion was clearly demonstrated only on MRI. To the best of our knowledge, there have been no previous reports of an intramedullary lesion caused by periosteal chondrosarcoma demonstrated on MRI.

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 ...

Medullary cavity diameter of metacarpal and metatarsal bones in cats
Veterinary and Comparative Orthopaedics and Traumatology, 2014SummaryObjectives: To compare radiography and computed tomography (CT) for the evaluation of medullary cavity diameters of metacarpal and metatarsal bones in cats and to analyse their correlation with intramedullary pin size.Methods: Radiography and CT were performed in cadavers (n = 12).

Aging changes in the medullary cavity of the proximal femur in American Blacks and Whites
American Journal of Physical Anthropology, 1979AbstractThis study explores changes with age in the medullary cavity in an area of the femur which is becoming of increasing clinical interest. It is based on measurements of medial‐lateral and posterior‐anterior radiographs of the proximal one‐third of the right femur, below the greater trochanter.

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 Significance of the Medullary Cavity for the Mechanical Stressing of the Tubular Bone
1980Grunewald (1920) asserted that bone is lighter because of its medullary cavity. His first argument is based on the fact that a tube requires less material than a solid rod of equal resistance to bending and of the same length. The diagram (Fig. 1 a-d) gives with figures the effect of the tubular construction on the amount of material required by a rod ...

Medullary Cavity Stenosis of the Metacarpals
CLINICAL NUCLEAR MEDICINE, 1997Medullary cavity stenosis of the metacarpals is a norma variant of no clinical significance. Its radiographic appearance consists of endosteal cortical thickening with narrowing of the medullary space of the involved meta carpals. According to the authors, the scintigraphic appearance of this variant has not been previously described.

Catheterization of the Medullary Cavity of Long Bones
Seminars in Musculoskeletal Radiology, 1997Vascular catheterization techniques were used in bones to allow access to the entire medullary cavity through a minimal percutaneous approach. The study was carried out on human and animal anatomical specimens and in living sheep. After oblique penetration at an angle of approximately 40û to the surface of the cortical bone, we attempted to pass in the
