6. Outcome Measures: All patients will be followed on an inpatient or outpatient basis (as applicable) for a period of 12 months post-operatively. Residents, attendings and study coordinators will perform data collection. All patients with suspected wound infection will undergo MRI with contrast for verification, unless there is gross evidence of infection (ex. purulent drainage from the incision, erythema and swelling). A CT scan with contrast will be obtained in those patients who are unable to undergo MRI for various reasons (pacemaker, metallic foreign bodies, fresh vascular stents, etc.). All wound data will be collected and recorded in specific data forms at each clinical encounter.
