What is bony fusion?

What is bony fusion?

Bony fusion was generally defined as “the presence of trabecular bridging” and/or “the absence of motion”. Fusion was accomplished in 90.1% of patients at the final follow-up. No gold standard for assessment could be derived from the results.

What is the cause of bone fusion?

Injury or fractures to the bones in the spine. Weak or unstable spine caused by infections or tumors. Spondylolisthesis, a condition in which one vertebrae slips forward on top of another. Abnormal curvatures, such as those from scoliosis or kyphosis.

What is a spinal fusion called?

Vertebrae are the small, interlocking bones of the spine. In spinal fusion, extra bone is used to fill the space that usually exists between the two separate vertebrae. When the bone heals, there’s no longer space between them. Spinal fusion is also known as: arthrodesis.

What does getting a fusion mean?

Spinal fusion is surgery to permanently connect two or more vertebrae in your spine, eliminating motion between them.

What is ankylosis of the spine?

“Ankylosis” means fused bones or other hard tissue. “Spondylitis” means inflammation in your spinal bones, or vertebrae. Severe cases can leave your spine hunched. There’s no cure for AS. But medication and exercise can ease pain and help keep your back strong.

What is cadaver bone?

There are several sources of bone that can be used: “cadaveric” or donated human bone which has been processed, xenograft or animal bone (usually cow, horse, or pig bone), artificial/synthetic bone, and autograft (bone taken from your own body).

What is cartilage?

Cartilage is the main type of connective tissue seen throughout the body. It serves a variety of structural and functional purposes and exists in different types throughout our joints, bones, spine, lungs, ears and nose.

What is fusion in medical term?

The joining of two bones into a single unit, thereby obliterating motion between the two. 7. The process in which two membranes are joined together.

Which bones of the spine are typically fused?

The bottom of the spine is called the sacrum. It is made up of several vertebral bodies usually fused together as one. The remaining small bones or ossicles below the sacrum are also fused together and called the tailbone or coccyx.

Which vertebrae are fused?

sacrum
The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.

How does ankylosis occur?

Ankylosis occurs when partial root resorption is followed by repair with either cementum or dentine that unites the tooth root with the alveolar bone, usually after trauma.

What is the meaning of fusion in chemistry?

Fusion Definitions in Physics and Chemistry. Fusion means combining lighter atomic nuclei to form a heavier nucleus. Energy is absorbed or released by the process and the resulting nucleus is lighter than the combined masses of the two original nuclei added together.

What is gene fusion in biology?

Fusion Definition in Biology and Medicine Fusion is the process by which uninuclear cells combine to form a multinuclear cell. This process is also known as cell fusion. Gene fusion is the formation of a hybrid gene from two separate genes.

What is the role of fusion reactions in energy production?

Fusion reactions are the source of energy production in stars and are responsible for the conversion of protons into heavier elements. They are also a potential energy source for modern industrial society.

What is nuclenuclear fusion?

Nuclear fusion is the combination of two or more atomic nuclei to form one or more different nuclei. In other words, it is a form of transmutation that changes one element into another.
