title: A technique to circumvent subcutaneous cement tracts during percutaneous vertebroplasty.
abstract: The deposition of a subcutaneous cement tract is a potential complication of percutaneous vertebroplasty. These tracts can be a source of pain and tenderness for the patient. We describe a case of symptomatic cement deposition within a needle tract in the subcutaneous tissues that required surgical removal, and we describe a technique to prevent this complication in a second patient, by using needle redirection to cut across the cement core.
