Surgical site infections (SSI) are not uncommon, especially in specific high-risk groups including spinal deformity and tumor (i.e. metastatic spine surgery) surgery. Well-recognized measures have been adopted to reduce surgical site infection, and the use of topical vancomycin powder has gained popularity in recent years. Given the lack of high-quality evidence for the use of topical vancomycin to reduce surgical site infections in open posterior spine surgery, which is currently the most common approach to spine surgery, it is crucial to study the use of vancomycin powder in reducing surgical site infections. This study is a prospective, single-blinded open label randomized controlled trial, with one arm of patients having local administration of 1g vancomycin powder which will be placed in the deep wound and subcutaneous layer prior to closure of surgical site by the orthopaedic surgeon, whereas the control arm will be without such application of vancomycin. Both arms of patients will still be undergoing the same operation procedures, as well as postoperative local wound drainage and wound care. This study will provide insights on the reduction rate in superficial and/or deep surgical site infection, and also assess the cost-effectiveness of using topical vancomycin in reducing surgical site infection between different disease groups, as well as any postoperative serum vancomycin toxicity and renal impairment. These proposed findings will provide valuable information for clinicians and institutions on future measures for surgical site infection of open posterior spine surgery.
