There was a proximal migration of nail into medullary cavity of clavicle in two patients.
However, for some patients, the uncemented prosthesis cannot fit into the medullary cavity, for example, "stovepipe" type femoral medullary cavity, thus a cemented prosthesis is used.
Diameter of medullary cavity of left femora was taken by using linear micrometer.
Furthermore, reformed medullary cavity, static fracture line gap and substantially hard fracture site suggests for fracture union.
Another explanation might be that pressure at the joints caused necrosis of the local bone tissues, compressing the vessels inside the medullary cavity, thus resulting in ischemia and necrosis of local tissues, followed by the structural damage to the trabecular bone.
Vascular canals mostly anastomose with each other and sometimes open in the medullary cavity, creating the bone's uneven surface.
The central type of ossifying fibroma arises from the endosteum or the periodontal ligament adjacent to the root apex and expands from the medullary cavity of the bone, and the peripheral type occurs on the soft tissues overlying the alveolar process.
The association of the tumor with the bone cortex and medullary cavity is better demonstrated by cross-sectional imaging such as computed tomography and magnetic resonance imaging.
They were inserted from the medial and lateral sides at the level of the tibial tuberosity and were introduced into the medullary cavity by pushing them down to the level of the distal metaphysis.
Metabolic disorders, such as hypervitaminosis A, pseudohypoparathyroidism, and renal osteodystrophy, could be excluded based on their radiological appearance of periosteal new bone formation in diaphysis with sparing of the medullary cavity (hypervitaminosis A) and generalized osteosclerosis (pseudohypoparathyroidism, and renal osteodystrophy) along with laboratory abnormalities (i.e., hypocalcemia and hyperphosphatemia in pseudohypoparathyroidism).
Furthermore, these lesions are characteristically cortically-based and eccentrically located within the medullary cavity. As seen in the radiograph above, the lesion should have well-defined borders, with no signs of periostitis, cortical breakthrough, soft tissue mass, or edema around the lesion
(1) Sparing of the medullary cavity within the long bones is characteristic of the disorder, resulting in normal haematopoietic function.
