Case:
One of our adult patients with polycythemia vera developed sciatic nerve palsy following a bone marrow aspiration (BMA). The patient was on oral anticoagulants and developed a large hematoma in the posterior thigh, resulting in sciatic nerve compression. Treatment involved hematoma evacuation and nerve decompression, which helped alleviate severe pain and enabled neurological recovery.
Conclusion:
Although BMA is generally a safe procedure, it can rarely lead to hemorrhage, particularly in patients with myeloproliferative disorders and those taking anticoagulants. It is crucial to be aware of this possibility, carefully select patients, and take precautions for individuals at high risk.

Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
