Contralateral psoas seroma after transpsoas lumbar interbody fusion with bone morphogenetic protein-2 implantation.
The lateral transpsoas approach to interbody fusion of the lumbar spine (lateral lumbar interbody fusion [LLIF]) with recombinant human bone morphogenetic protein-2 (BMP-2) augmentation has been increasingly performed in recent years. Potential side effects and adverse sequelae of BMP-2 in the acute setting remain to be fully elucidated. ⋯ A serous psoas muscle fluid accumulation after BMP-2 implantation may rarely occur contralateral to the surgical approach for LLIF. Further characterization of complications related to BMP-2 implantation after lumbar spinal surgery will help guide preoperative informed decision making and the management of this unusual postoperative adverse event.

Scoliosis is a significant cause of disability and health-care resource utilization in the United States. ⋯ Differences were found in the selection of surgical versus nonsurgical treatments, as well as inhospital morbidity for hospitalized idiopathic scoliosis patients based on ethnic and socioeconomic variables. This may in part be because of differences in access to the resources of large teaching hospitals for different ethnic and socioeconomic groups or variability in severity of scoliosis among these groups that was not captured in this database.

Patients with spinal tumors are often referred for preoperative angiography and embolization before surgical resection to minimize intraoperative bleeding. ⋯ Preoperative embolization was angiographically effective in most cases. Avid gadolinium enhancement (Grade 3) on MRI was not predictive of hypervascularity on angiography. Furthermore, hypervascularity was not restricted to classically vascular tumors, such as RCC, as it was noted in some patients with breast and prostate cancer. However, with the available numbers, the quality of preoperative embolization did not significantly affect intraoperative blood loss. A future prospective randomized controlled study may be warranted to better characterize the benefits of preoperative embolization for spinal tumors.

Spinal epidural hematoma (SEH) is a rare, yet potentially devastating complication of spinal surgery. There is limited evidence available regarding the risk factors and timing for development of symptomatic SEH after spinal surgery. ⋯ Symptomatic postoperative SEH is rare, occurring in 0.22% of cases. Alcohol consumption greater than 10 units a week, multilevel procedure, and previous spinal surgery were identified as risk factors for developing SEH. Spinal epidural hematoma often presents early in the postoperative period, highlighting the importance of close patient monitoring within the first 4 hours after surgery. This study suggests that earlier surgical intervention may result in greater neurological recovery.
