Definition/Description[edit | edit source]
Heterotopic Ossification (HO) refers to the formation of lamellar bone inside soft tissue structures where bone does not normally exist. This process can occur in structures such as the skin, subcutaneous tissue, skeletal muscle, and fibrous tissue adjacent to bone. In more rare forms, HO has also been described in the walls of blood vessels and intra-abdominal sites such as the mesentery.[1]
Research suggests four factors which contribute to formation of heterotopic bone: 1) inciting event (usually trauma), 2) a signal from the site of injury, 3) a supply of mesenchymal cells whose genetic machinery is not fully committed, 4) an environment which is conducive to the continued formation of new bone.[1] These factors are discussed more indepth in the Etiology/Causes section.
HO was fisrt described by by Patin in 1692 while working with children diagnosed with myositis ossificans progressiva.[2] It was not until 1918 when Dejerine & Ceillier detailed the anatomical, clinical, and histological features of ectopic bone formation in soldiers who sustained spinal injuries during World War I.[3]
