Review Meta Analysis
Complications of intraoperative epidural steroid use in lumbar discectomy: a systematic review and meta-analysis.
OBJECT The authors' aim in this paper was to review the intraoperative use of epidural steroids in lumbar discectomy surgery with a focus on surgical complications. METHODS A comprehensive literature search was done using PubMed, MEDLINE, and the Cochrane Central Registry of Controlled Trials. Relevant papers were retrieved and analyzed. ⋯ CONCLUSIONS There is good evidence that epidural steroids can decrease pain in the short term and decrease the usage of postoperative narcotics after lumbar spinal surgery for degenerative spinal disease. The authors' results demonstrate a trend toward increased infection with epidural steroid use, but there was not a statistically significant difference. More studies are needed to validate the long-term risk/benefit ratio of epidural steroids in lumbar discectomy.

Complications from the use of intrawound vancomycin in lumbar spinal surgery: a systematic review.
OBJECT The use of intrawound vancomycin is rapidly being adopted for the prevention of surgical site infection (SSI) in spinal surgery. At operative closure, the placement of vancomycin powder in the wound bed-in addition to standard infection prophylaxis-can provide high concentrations of antibiotics with minimal systemic absorption. However, despite its popularity, to date the majority of studies on intrawound vancomycin are retrospective, and there are no prior reports highlighting the risks of routine treatment. ⋯ CONCLUSIONS Intrawound vancomycin use appears to be safe and effective for reducing postoperative SSIs with a low rate of morbidity. Study disparities and limitations in size, patient populations, designs, and outcomes measures contribute significant bias that could not be fully rectified by this systematic review. Moreover, care should be exercised in the use of intrawound vancomycin due to the lack of well-designed, prospective studies that evaluate the efficacy of vancomycin and include the appropriate systems to capture drug-related complications.

OBJECT Structural spinal surgery yields improvement in pain and disability for selected patients with spinal stenosis, spondylolisthesis, or a herniated intervertebral disc. A significant fraction of patients exhibit persistent postoperative neuropathic pain (PPNP) despite technically appropriate intervention, and such patients can benefit from spinal cord stimulation (SCS) to alleviate suffering. The complication profile of this therapy has not been systematically assessed and, thus, was the goal of this review. ⋯ CONCLUSIONS Spinal cord stimulation can provide for improved pain and suffering and for decreased narcotic medication use among patients with PPNP after lumbar spinal surgery. This study reviewed the prospective studies forming the evidence base for this therapy, to summarize the complications encountered and, thus, best inform patients and clinicians considering its use. There is a significant rate of minor complications, many of which require further surgical intervention to manage, including lead migration or implant infection, although such complications do not directly threaten patient life or function.

Review
Reconstruction of open wounds as a complication of spinal surgery with flaps: a systematic review.
OBJECT A systematic review of the available evidence on the prophylactic and therapeutic use of flaps for the coverage of complex spinal soft-tissue defects was performed to determine if the use of flaps reduces postoperative complications and improves patient outcomes. METHODS A PubMed database search was performed to identify English-language articles published between 1990 and 2014 that contained the following phrases to describe postoperative wounds ("wound," "complex back wound," "postoperative wound," "spine surgery") and intervention ("flap closure," "flap coverage," "soft tissue reconstruction," "muscle flap"). RESULTS In total, 532 articles were reviewed with 17 articles meeting the inclusion criteria of this study. ⋯ The indications for flap coverage after onset of wound complications included hardware exposure, wound infection, dehiscence, seroma, and hematoma. Flap coverage was shown to decrease the number of surgical debridements needed and also salvage hardware, with the rate of hardware removal after flap coverage ranging from 0% to 41.9% in 4 studies. CONCLUSIONS Prophylactic coverage with flaps in high-risk patients undergoing spine surgery reduces complications, while therapeutic coverage following wound complications allows the salvage of hardware in the majority of patients.

OBJECT There are a variety of surgical positions that provide optimal exposure of the dorsal lumbar spine. These include the prone, kneeling, knee-chest, knee-elbow, and lateral decubitus positions. All are positions that facilitate exposure of the spine. ⋯ CONCLUSIONS This work presents a systematic review of positioning-related complications following prone, knee-chest, and other positions used for lumbar spine surgery. Numerous evidence-based recommendations for avoidance of these potentially severe complications associated with intraoperative positioning are discussed. This investigation may serve as a framework to educate the surgical team and decrease rates of intraoperative positioning complications.
