Histopathological examination of bone biopsy for diagnosis of bends (osteonecrosis)

Why is this test done?

Your healthcare provider may recommend this test if you have symptoms like joint pain, swelling, or limited movement in your hips, knees, or other joints. It could also be suggested if you’ve had a history of conditions that increase your risk of bone damage, such as long-term steroid use, trauma, or certain blood disorders.

What happens during the test?

A small piece of bone is taken from your body, usually from the hip or knee, under local anesthesia. The sample is then sent to a lab for microscopic examination by a pathologist to look for signs of tissue damage, cell changes, or other abnormalities related to conditions like avascular necrosis.

What does the test involve after collection?

The bone sample is processed and stained to highlight different tissue structures. A pathologist examines the tissue under a microscope to identify any abnormalities, such as dead or dying bone cells, inflammation, or other signs of disease. This detailed review helps determine if you have conditions like avascular necrosis or other bone-related issues.

What does the test result mean?

The result will describe the condition of your bone tissue, such as whether there are signs of avascular necrosis, infection, or other bone diseases. Your doctor will use these findings alongside your symptoms and medical history to guide treatment decisions.
