Bony ankylosis is a medical condition in which two bones in the body become fused together due to abnormal bone growth. It is also known as bony fusion, bone anchylosis, or bone bridging. The fusion can occur in any part of the body, but is most commonly seen in the spine, pelvis, and extremities.
The fusion of the bones is caused by a variety of conditions, including trauma, arthritis, or infection. In some cases, ankylosis can also be a result of congenital or genetic disorders such as achondroplasia. The abnormal bone growth occurs when the body produces new bone that connects two already existing bones together. This new bone may be rigid and immobile, which can lead to a decrease in range of motion and difficulty with movement.
Symptoms of bony ankylosis can vary depending on the location of the fusion. In the spine, it may cause stiffness and pain, as well as a decrease in flexibility. In the extremities, ankylosis may cause a decrease in mobility and strength, as well as a decrease in range of motion. Treatment for bony ankylosis is typically focused on pain relief and restoring mobility and range of motion. This can be done through physical therapy, joint injections, and in some cases, surgery.
