What is heterotopic ossification hip replacement?

What is heterotopic ossification hip replacement?

Heterotopic ossification (HO) is the presence of the lamellar bone within soft tissues where the bone physiologically does not exist. One of the most common forms of HO is that which intervenes in periarticular soft tissue after hip replacement, with a mean incidence of 53 % reported in the literature [1].

What causes heterotopic ossification?

When Bone Grows in Soft Tissues or Muscles Often abbreviated “H.O.,” heterotopic ossification can occur just about anywhere in the body. Heterotopic bone often forms after surgery, injury, or sometimes for unknown reasons.

How can heterotopic ossification be prevented?

Usually, treatment will include gentle range of motion of the joints and some physical therapy. Your doctor may also prescribe medications to slow down or stop the abnormal growth of bone. When HO severely affects your movement or causes excruciating pain, surgery may be needed.

Does heterotopic ossification go away?

Heterotopic ossification (HO) is seldom excised, because pain relief is often inadequate and improvement in range of motion (ROM) may not last. In established cases of HO following total hip arthroplasty (THA), excision may be performed.

How long does it take to recover from heterotopic ossification surgery?

Patients must have enough time before surgical resection, however, to recover from the often numerous orthopedic injuries and trauma—either local or systemic—that cause the heterotopic ossification, and the area must be well demarcated, he said. Six months gives most patients time to resolve many of their injuries, Dr.

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.

What does heterotopic ossification mean?

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 happens during ossification?

This process occurs primarily in the bones of the skull. In other cases, the mesenchymal cells differentiate into cartilage, and this cartilage is later replaced by bone. The process by which a cartilage intermediate is formed and replaced by bone cells is called endochondral ossification.

What is a heterotopic hip?

Heterotopic ossification (HO) after hip arthroscopy is the abnormal formation of mature lamellar bone within extra skeletal soft tissues. HO may lead to pain, impaired range of motion and possibly revision surgery.

Is heterotopic ossification common?

Heterotopic ossification is a common complication of total hip arthroplasty. Its prevalence is not the same in all of the patient groups. Frequency of HO varies from 15 to 90%.

Where is heterotopic ossification most common?

Although HO can be found at any site, it is most prevalent in the major joints such as the hip, elbow, shoulder and knee.

Is heterotopic ossification rare?

J Am Acad Orthop Surg.

Which joint is the most common site for heterotopic ossification in burn patients?

By far the most common sites affected are the elbows resulting in marked reduction in ROM and function, often associated with ulnar nerve compression. Involvement of other joints including shoulders, hips, knees, forearms15 and the tempromandibular joints (TMJ)16 have been documented.

How is heterotopic ossification diagnosis?

Radiography. Radiographs are most often the first imaging study used to detect nongenetic HO and often have distinctive features that allow diagnosis. Unusual roentgenographic findings should prompt a second imaging modality. In the early phases of HO, no ossification can be found by radiographs.

Why does ossification happen?

Soon after the osteoid is laid down, inorganic salts are deposited in it to form the hardened material recognized as mineralized bone. The cartilage cells die out and are replaced by osteoblasts clustered in ossification centres. Bone formation proceeds outward from these centres.

What is H O TBI?

HO = heterotopic ossification; TBI = traumatic brain injury; S-TBI = severe traumatic brain injury.

What is osteolysis?

Osteolysis is a progressive condition where bone tissue is destroyed. In this process, bones lose minerals (mostly calcium), softens, degenerates and become weaker.

How can osteolysis be prevented?

What can I do to manage osteolysis and prevent fractures?

1. Keep follow-up appointments. You may need to visit your healthcare provider often if you have had surgery to replace a damaged joint.
2. Take medicines as ordered by your healthcare provider.
3. Exercise safely.

How do you fix osteolysis?

Nonsurgical treatment options include:

1. Rest, as much as 6 weeks for a distal clavicle osteolysis injury to heal.
2. Activity modification by using different hand positions while lifting weights, using lighter weights and avoiding certain exercises.
3. Anti-inflammatory medications.
4. Steroid injections into the joint.
