How come the hip bone traditionally where bone marrow is extracted from?

How come the hip bone traditionally where bone marrow is extracted from?

Access: Good question. 1) bone marrow is present in multiple locations including the "long bones" (arms, legs), sternum, and hips , 2) the psis - posterior superior iliac spine (hip) is relatively flat with a thinner cortex, so is easier to access and is not near vital structures (like the heart and lungs). ...Read more

Can jaw bone grow after bone grafting?

Regeneration?: Bone grafting mostly produce a regeneration effect, which meant eestablish a loss bone height (hard to achieve in horizontal defect) or bone width (easily achieved). Your jaw bone growth can only achieved with bmps (bone morphogenetic proteins) and patient should be at young age. ...Read more

Do granules of a dental bone graft move around? Like under your interior jaw bone near the extraction site.

2 doctors agreed:
Do granules of a dental bone graft move around? Like under your interior jaw bone near the extraction site.

Hopefully minimal: One of the reason why the bone graft fail is the instability or movement of the graft. True grafting required graft stabilization with membrane, cages (titanium fixture to protect graft), or screw in the case of block graft. Micromovement of graft will hinder the fibroblast migration and adhesion and interupt vascular genesis. Must achieve good clotting and full closure for graft stabilization. ...Read more

What are the short/long term effects of a hairline skull fracture. 3" in length from lambdoid suture forward toward the temporal bone.

What are the short/long term effects of a hairline skull fracture.  3" in length from lambdoid suture forward toward the temporal bone.

Usually none: In an adult, the type of fracture you describe really has no long-term effects. Short term problems really have to do with any associated intracranial problems (hemorrhages, contusions, etc.). Potential fractures requiring treatment are ones that are exposed through the scalp (open), significantly depressed, ones involving skull sinuses, which can leak csf, or "growing" fractures in young children. ...Read more

What is bone resorption and bone formation defect if osteoporosis?

What is bone resorption and bone formation defect if osteoporosis?

One process is: Greater. In osteoporosis, bone resorption is more prevalent then bone formation. As a result, a negative bone balance occurs and bone loss will occur and over time osteopenia or osteoporosis will occur. Medications such as Fosamax and Boniva (ibandronate) slow down bone resorption. ...Read more
