Abstract:

BACKGROUND: Heterotopic ossification is a common complication after total hip arthroplasty, and there are no obvious clinical symptoms, but more severe heterotopic ossification can cause postoperative pain and joint mobility. The pathogenesis of heterotopic ossification is not fully understood, and there are many factors that can increase the incidence of heterotopic ossification. Because there is no effective non-surgical treatment of mature heterotopic ossification in clinical practice, it is especially important for the early diagnosis of heterotopic ossification.

OBJECTIVE: To summarize the current research and progress of heterotopic ossification after total hip arthroplasty.
METHODS: The first author searched PubMed, Springerlink and CNKI databases for the articles between 2008 and 2018. The keywords were “total hip arthroplasty, heterotopic ossification” in English and Chinese, respectively. Totally 278 English articles and 97 Chinese articles were retrieved, and 53 eligible articles were included for analysis and summary.
RESULTS AND CONCLUSION:(1) At present, the pathogenesis of heterotopic ossification is not fully understood, and is related to systemic and local factors. (2) The risk factors for heterotopic ossification are divided into variable factors and invariable factors, and age, man, ankylosing spondylitis, history of hip surgery, hip ankylosis and other factors can increase the incidence of heterotopic ossification. (3) The diagnosis of heterotopic ossification mainly depends on imaging examination. The imaging findings of heterotopic ossification in different periods are different, and the sensitivity and specificity of different imaging examination methods for heterotopic ossification are also different. (4) There are various conclusions about the risk factors of heterotopic ossification, and there is no recognized best imaging examination method, but many research and analysis results can provide a basis for clinical prevention and diagnosis of heterotopic ossification after total hip arthroplasty.
