Shiu B, et al. - Researchers ascertained the incidence and characteristics of complications occurring secondary to therapeutic anticoagulation in adult spine trauma patients. To quantify complications secondary to postoperative therapeutic anticoagulation in spine patients this is the first study. An unplanned reoperation rate of 18%, including a 3% incidence of spinal epidural hematoma was experienced by postoperative spine trauma patients who underwent therapeutic anticoagulation. Seemingly the overall rate of reoperation (31%) was driven by therapeutic anticoagulation using heparin infusion compared with low-molecular-weight heparin (LMWH).
