What causes heterotopic ossification?

What causes heterotopic ossification?

HO occurs after other injuries, too. HO has been known to occur in cases of traumatic brain injury, stroke, poliomyelitis, myelodysplasia, carbon monoxide poisoning, spinal cord tumors, syringomyelia, tetanus, multiple sclerosis, post total hip replacements, post joint arthroplasty, and after severe burns.

What is a heterotopic ossification?

Heterotopic ossification is abnormal bone formation within muscle and soft tissues, an unfortunately common phenomenon that typically occurs weeks after an injury or surgery. Patients with heterotopic ossification experience decreased range of motion, swelling and pain.

Can heterotopic ossification be treated?

The two main treatments available are radiation therapy and NSAIDs. Bisphosphonates have been used in the past, but their use has been discontinued as they only postpone ossification until treatment is stopped.

Does heterotopic ossification require surgery?

Heterotopic ossification (HO) presents a substantial barrier to rehabilitation of patients who have incurred severe trauma. However, surgical excision of HO is fraught with complications, including the development of recurrent ectopic bone.

What doctor treats heterotopic ossification?

When heterotopic ossification (HO) is severe or problematic and causes pain, or affects a patient’s mobility and function, it should be managed by an orthopaedic surgeon. Occasionally, that involves surgery or a revision procedure to resolve the problem.

Where does heterotopic ossification occur?

HO occurs with the highest frequency at the elbow, followed by the shoulder, and subsequently the hip. Owing to its location around joints, those patients with burn injury–induced HO often have a restriction in the range of motion as an early manifestation of the ossification.

Where is heterotopic ossification most common?

The most common sites for neurogenic HO are the hips, elbows (extensor side), shoulders, and knees. Uncommon sites of HO that may be encountered in a rehabilitation setting are incisions, kidneys, uterus, corpora cavernosum, and the gastrointestinal (GI) tract.

How long does heterotopic ossification last?

Prognosis is generally good after surgery. Mean time from injury to surgery is 3.6 years. Once the surgery is performed, studies have shown that average ROM in the hip can improve from 24.3 to[5].

Is heterotopic ossification a disability?

Heterotopic ossification is a condition affecting an appreciable minority of critical care patients; it can have long-lasting effects on recovery and return to functional status. Ectopic bone forms in soft tissues near the large joints, causing pain, swelling, limitation of movement and ultimate disability.

How do you remove heterotopic ossification?

In the case of heterotopic ossification, the only effective treatment is excision, also called resection. Dr. Nwachukwu will often delay surgical excision for 5-6 months following the initial hip trauma and/or inciting surgery, allowing the bone growth to mature and for a distinct fibrous capsule to develop.

Who is at risk for heterotopic ossification?

Hip ankylosis, male gender, and previous history of HO are said to be risk factors with a significant level. Diagnosis is based on a single AP radiograph: the Brooker classification that divides HO into four grades is the most commonly used.

What is HO surgery?

ABSTRACT. Heterotopic ossification (HO) is a diverse pathologic process, defined as the formation of extraskeletal bone in muscle and soft tissues. HO can be conceptualized as a tissue repair process gone awry and is a common complication of trauma and surgery.

What is heterotopic ossification?

Abstract 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.

What is the role of irradiation in the prevention of heterotopic ossification?

Hoff P, Rakow A, Gaber T, et al. Preoperative irradiation for the prevention of heterotopic ossification induces local inflammation in humans. Bone. 2013;55(1):93–101.

Does burn injury enhance bone formation in heterotopic ossification model?

How many cases of heterotopic ossification are there in spinal cord injury?

In‐hospital outcomes following single‐dose radiation therapy in the treatment of heterotopic ossification of the hip following spinal cord injury—an analysis of 444 cases. Spinal Cord. 2017;55(3):244–6.
