The Incidence of Heterotopic Ossification After Cementless Total Hip Arthroplasty

Prophylaxis of Heterotopic Ossification of the Hip: Systematic Review and Meta-Analysis

“…Severe HO is a potentially serious complication in hip surgery [1,12,23]. Although most patients are asymptomatic, two articles including 10,826 subjects from 37 studies suggest HO may be associated with substantial compromise of function and range of motion even at low grades, although most studies report high functional levels except at the highest grades using various outcome measures [10,22].…”

Bone mineral density is not related to heterotopic ossification after total hip arthroplasty

“…In the present study, the patient-related risk factors of HO after THA have been investigated to predict which patients are likely to have HO [1,2,10,13,19,20,23,24]. We measured BMD of patients who were scheduled to undergo THA to determine whether patients with higher BMD levels more often have HO after THA.…”

“…These factors were classified into three categories: (1) disease related (e.g., ankylosing spondylitis [1,13,24]); (2) operation technique related (e.g., soft tissue trauma [1] and surgical approach [19]); and (3) patient-related risk factors (e.g., male [2,20], hypertrophic osteoarthritis (OA) [1,2,14,20,23], and history of HO [10]). …”

Does a Plastic Drape Reduce Incidence of Heterotopic Ossification After Hip Resurfacing?

“…The incidence of HO after THA in the literature ranges from 5% to 90%, but recent studies suggest an incidence of 32% to 67% [2,8,12,22]. For some patients, HO is an incidental radiographic observation, but as many as 10% can experience functional impairments, such as pain and decreased ROM due to the inflammatory reaction produced by HO [22]. HO has also been associated with trauma, burns, genetic disorders, and soft tissue sarcomas [19,26,31].…”

“…Surgeons cannot control patient-related risk factors for HO, including ankylosing spondylitis, diffuse idiopathic skeletal hyperostosis, male gender, previous hip surgery, and history of heterotopic bone, but surgical factors can be controlled [2,3,8,18,22,25,33,35,[52][53][54]58]. Surgical risk factors, including operative time, approach, difficulty of the procedure, soft tissue trauma, and bone debris, have been linked to increased rates of ectopic bone [2,3,8,18,20,21,25,30,33,48,53,54].…”
