Farshad M, et al. - Researchers examined the incidence of revision surgery as a result of steadfast CSF leakage and medical complications following quick or late postoperative ambulation after incidental durotomy (ID) during decompressive spinal surgery. Sixty patients were randomly allocated to either early postoperative ambulation (EA, n = 30) or flat bed rest (BR) for 48 h (BR, n = 30). As a result of persisting CSF leakage, two patients in the BR group and two patients in the EA group had to undergo revision surgery. Medical complications correlated with prolonged immobilization was experienced by four patients in the BR group. Therefore, the results of this study designate no advantage of prolonged BR following an appropriately fixed ID in lumbar spine surgery.
