Increased Postoperative Pseudosubluxation after Total Hip Arthroplasty: A Complication Accelerated by the COVID-19 Pandemic

摘要

The severe acute respiratory syndrome coronavirus 2 (coronavirus disease 2019) has accelerated the utilization of spinal anesthesia for total hip arthroplasty. Subsequently, an increase in postoperative prosthetic subluxation has been noted at our institution. We report on our experience with this complication in six patients. We also reviewed the literature for similar cases and potential risk factors. This complication may be treated by either closed reduction or watchful waiting. However, no modifications to postoperative protocols are necessary.
