Postoperative outcomes of subaxial cervical spine metastasis: Comparison among the anterior, posterior, and combined approaches.

The three most utilized approaches for surgical treatment include the anterior, posterior, and combined approaches. However, despite increasing surgical volume, data on the postoperative complication profiles of different operative approaches for this patient population is scarce.
