Acute traumatic L5-S1 spondylolisthesis is a rare condition, almost exclusively the result of major trauma, frequently associated with L5 transverse process fracture and neurologic deficit. In recent years, open reduction and internal fixation with posterior stabilization has been the method of treatment most frequently reported. In the current case, the lesion was found in a victim of an automobile accident. ⋯ A computed tomography scan revealed several fractures in the posterior parts of L5 and anterior displacement of L5 on S1. A magnetic resonance imaging (MRI) scan verified that the lesion was indeed acute by showing the ruptured L5 disc and posterior ligaments, thereby demonstrating the importance of MRI in the planning of the treatment of these lesions. This case was successfully treated with an acute circumferential instrumented L4-S1 spondylodesis.

Randomized Controlled Trial Clinical TrialThe use of postoperative subcutaneous closed suction drainage after posterior spinal fusion in adolescents with idiopathic scoliosis.
BACKGROUND The purpose of this prospective study was to assess the impact of closed suction drainage on transfusion requirements, frequency of dressing changes, and wound healing following posterior spinal fusion in adolescents with idiopathic scoliosis. METHODS Thirty patients were randomly assigned to one of two groups: drain or no drain. ⋯ Three of 12 patients in the undrained group demonstrated a wound complication rate compared with no complications in the drained group. CONCLUSION In conclusion, subcutaneous closed suction drainage can improve immediate postoperative wound care without significantly increasing blood loss and transfusion requirements for patients undergoing surgery for idiopathic scoliosis.

Clinical Trial Controlled Clinical TrialPerioperative complications of threaded cylindrical lumbar interbody fusion devices: anterior versus posterior approach.
Few data are available to evaluate approach-related differences in perioperative complications with lumbar interbody fusion devices. Complications occurring in the intraoperative and immediate postoperative period were identified and categorized for 31 consecutive posterior lumbar interbody fusions (PLIFs) and 88 consecutive anterior lumbar interbody fusions (ALIFs). In this study, all lumbar interbody fusions were conducted with threaded cylindrical devices as stand-alone internal fixation devices. ⋯ The relative risk of having a major postoperative complication was 6.8 times higher in the PLIF group than the ALIF group. Anterior approached patients tended to have visceral (ileus, 6%) and vascular (deep venous thrombosis, 2%) complications. In the posterior group, complications were neurologic and dura related (pseudomeningocele, 16%; epidural hematoma, 3%) and occurred most frequently in patients that had had previous posterior lumbar surgery (31% with major complication).
