Abstract
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. There has been a substantial amount of recent research on the pathophysiology, prophylaxis and treatment of HO associated with open and arthroscopic hip surgery. This article reviews the literature on the aforementioned topics with a focus on their application in hip arthroscopy.
Highlights
Heterotopic ossification (HO) is the abnormal formation of mature lamellar bone within extraskeletal soft tissues
SUMMARY HO is the abnormal formation of mature lamellar bone within extraskeletal soft tissues
The most likely candidate cell responsible for HO is the mesenchymal stem cell (MSC), which proliferates into pathologic tissue under the stresses of post-operative tissue damage
Summary
Heterotopic ossification (HO) is the abnormal formation of mature lamellar bone within extraskeletal soft tissues. ABSTRACT Heterotopic ossification (HO) after hip arthroscopy is the abnormal formation of mature lamellar bone within extra skeletal soft tissues. The risk factors for HO in THA include patient related factors such as male gender [26], previous hip surgery [27] and history of HO [28].
