Review Meta Analysis
Epidural injections in prevention of surgery for spinal pain: systematic review and meta-analysis of randomized controlled trials.
Low back pain is debilitating and costly, especially for patients not responding to conservative therapy and requiring surgery. ⋯ Epidural steroid injections may provide a small surgery-sparing effect in the short term compared with control injections and reduce the need for surgery in some patients who would otherwise proceed to surgery.

Lateral spacers (LSs) are the standard of care for a lateral lumbar interbody fusion. However, various types of fixation, such as bilateral pedicle screws (BPSs), unilateral pedicle screws (UPSs), bilateral facet screws (BFSs), and lateral plates (LPs) have been reported to increase the stability of LSs. The biomechanics of a novel lateral interbody implant, which is an interbody spacer with an integrated plate and two bone screws (lateral integrated plate-spacer [IPS-L]), has not been investigated yet. ⋯ The IPS-L evaluated in the present study demonstrated equivalent biomechanical stability compared with standard lateral interbody fusion constructs. The addition of BPSs to the IPS-L showed significant reduction in ROM in FE, and the addition of BFSs showed significant reduction in ROM in FE and AR, compared with the integrated plate-spacer alone construct. The IPS-L with supplemental fixation may be a viable option for lateral interbody fusion. Long-term clinical studies are further required to confirm these results.

Repeated cohort studies have consistently demonstrated a survival advantage after en bloc resection for locally aggressive primary tumors in the sacrum. A sacrectomy is often required to remove the tumor en bloc, which may necessitate the sacrifice of sacral nerves. This can potentially result in functional complications, including the impairment of gait, bowel function, or bladder function. ⋯ Preoperative bladder, bowel, and motor functions, level of sacral tumor involvement, and corresponding level of sacrectomy were the greatest predictors of long-term bladder, bowel, and motor functions. There were no statistically significant changes in bladder, bowel, or motor functions from pre-op to 6 months post-op, and therefore, pre-op functional status was predictive of long-term function.

Surgical site infection (SSI) after spinal surgery can result in several serious secondary complications, such as pseudoarthrosis, neurological injury, paralysis, sepsis, and death. There is an increasing body of literature on risk factors, diagnosis, and specific intraoperative interventions, including attention to sterility of instrumentation, application of minimally invasive fusion techniques, intraoperative irrigation, and application of topical antibiotics, that hold the most promise for reduction of SSI. ⋯ Surgical site infections are a common multifactorial problem after spine surgery. There is compelling evidence that improved risk stratification, detection, and prevention will reduce SSIs.
