Heterotopic ossification is defined as the formation of bone within soft tissues, most frequently muscle tissue. The heterotopic ossification of muscles, ligaments and tendons is a potential complication following trauma, elective orthopaedic surgery, severe burns and neurological injury.

It differs from other disorders of bone mineralization in that HO occurs outside of the joint capsule, in planes not connected to periosteum. Heterotopic ossification (HO) is the presence of bone in soft tissue where bone normally does not exist. The acquired form of HO most frequently is seen with either musculoskeletal trauma, spinal cord injury, or central nervous system injury. For example, patients who have recently undergone total hip arthroplasty or have paraplegia after spinal cord injury are at risk for HO. 2015-12-01 2020-02-07 Heterotopic ossification (HO) is the growth of bone in places where it is not supposed to be. It can happen anywhere in the body. The hip, knees, shoulders, and elbows are the most common places.

Heterotopic ossification (HO) in connective tissues like tendons and ligaments severely damages tissue structure. The pathogenesis of HO remains unclear but may involve mTOR. The results presented here indicate that tendon stem/progenitor cells do not undergo osteochondrogenic differentiation when mTOR signaling is inactivated by gene knockout or rapamycin (RAPA) treatment. Meanwhile, it is

The severity of the condition varies; some patients have only small nodules of excess bone that can be noted on X-rays, but others suffer severe and debilitating pain. Heterotopic ossification refers to the formation of mature, lamellar bone in muscle and soft tissues where bone normally does not usually exist.

Heterotopic ossification (HO) is the formation of osseous tissue outside the skeleton. HO in malignant tumors of the digestive tract is extremely rare, as is ossification in metastatic lesions from HO-negative digestive tract tumors. Regarding the pathogenesis of HO, two theories have been proposed. The first is that the osteoblastic metaplasia of tumor cells (driven by the epithelial Symptomatic heterotopic ossification (HO) after total hip arthroplasty (THA) and total knee arthroplasty (TKA) is relatively rare. Patients at high risk for developing HO after THA include men with bilateral hypertrophic osteoarthritis, patients with a history of HO in either hip, and patients with posttraumatic arthritis characterized by hypertrophic osteophytosis.

The new bone generally does not involve the periosteum. Heterotopic ossification refers to the presence of bone in soft tissue where bone normally does not exist (extraskeletal bone). Lesions range from small clinically insignificant foci of ossification to large deposits of bone that cause pain and restriction of function. Risk Factors for Heterotopic Ossification: Injury severity score (ISS) High ISS is a risk: 11%: Traumatic brain injury (TBI) Higher incidence in the spastic limbs of the patient: 11%: Spinal cord injury: Complete SCI produces more HO than incomplete SCI. Cervical and thoracic SCI produces more HO than lumbar SCI. Younger age produces more HO The term "heterotopic ossification " refers to the growth of bone material in the soft tissues of the body, including muscles, tendons and fascia. The severity of the condition varies; some patients have only small nodules of excess bone that can be noted on X-rays, but others suffer severe and debilitating pain.

Heterotopic ossification can be conceptualized as a tissue repair process gone awry and is a common complication of trauma and surgery 1). Heterotopic ossification (HO) is defined as the process by which trabecular bone forms outside of the skeletal structure, occupying space in soft tissue where it does not normally exist. The current popular prophylactic treatment modalities include non-steroidal anti-inflammatory drugs (NSAIDs) and radiation therapy, although the literature remains inconclusive as to which is superior Heterotopic ossification (HO) is seldom excised, because pain relief is often inadequate and improvement in range of motion (ROM) may not last.
