Study Design.

Retrospective cohort analysis.

Objective.

To investigate the safety profile of outpatient versus inpatient single-level and multiple-level cervical disk replacement (CDR) by analyzing one-and two-year surgical outcomes and 90-day medical complications using a large patient database.

Summary of Background Data.

CDR is becoming a more desirable option for patients undergoing cervical spine procedures. Unlike anterior cervical diskectomy and fusion, CDR is motion-preserving and has been shown to reduce rates of adjacent segment disease. Current literature investigating outpatient versus inpatient CDR has shown a similar safety profile among the two cohorts. However, most of these studies have relatively small sample sizes with short-term follow-up.

Materials and Methods.

A retrospective cohort study was done using the PearlDiver patient database between 2010 and 2019. Patients who …
