Sclerosis of the bone causes narrowing of the
marrow cavity and bone marrow failure with consequent life-threatening pancytopenia and hepatosplenomegaly due to extramedullary hematopoiesis (2, 4).
In this study authors conclude that the assessment of geometrical parameters of second metacarpal bone (thickness of cortical layer,
marrow cavity diameter) along with optical density can be a useful tool for a preliminary diagnosis of mineralization disturbances, but this should be confronted with DXA examination [10].
But when fat cells start to fill the bone
marrow cavity -- a common symptom of sedentary behavior -- blood stem cells become less productive, and conditions such as anemia can result.
S, namely an erosive change in the cortical layer with no/minimal involvement of the
marrow cavity which is associated with periosteal new bone formation.
The long bones were abnormally modeled, had no bone
marrow cavity and frequently displayed a bone-within-bone appearance (Fig.
Although all patients with OP have dense, fragile bones and obliteration of the
marrow cavity, other manifestations of the disease vary.
Since the frontal bone is diploic with a
marrow cavity, it is susceptible to osteomyelitis.
The MarrowMiner shaft gains access to the bone
marrow cavity through the access guide to allow the removal of bone marrow through a single entry site.
CT fluoroscopic guidance permitted nearly "real-time" positioning of the trocar needle within the
marrow cavity of the sacrum, midway between the sacroiliac joint and the sacral foramina (Figure 2).
But scientists spotted unusual features in the
marrow cavity of a thigh bone in the American T-rex.
Scientists noticed unusual features in the
marrow cavity of the animal's thigh bone.
Each bone was transversally sectioned at the third proximal and distal part of the diaphysis level and following measurements were recorded: diameter of the bone, diameter of the
marrow cavity, wall thickness in the medial, lateral, dorsal and palmar quadrants and the total, cortical and
marrow cavity areas.
