There is no comparative study regarding surgical outcomes between microsurgical extraforaminal decompression (MeFD) and posterior lumbar interbody fusion (PLIF) for the treatment of lumbar foraminal stenosis (LFS). Therefore, the purpose of this study was to compare the surgical outcomes of LFS using two different techniques: MeFD alone or PLIF. ⋯ This study demonstrated that MeFD alone and PLIF have equivalent outcomes regarding improvement in disability at 1 year after surgery. However, the higher rate of revision surgery in the MeFD group should emphasize the technically optimal amount of decompression.

Abnormal anthropometry including comparably lower weight and body mass index (BMI) in the adolescent idiopathic scoliosis (AIS) population is increasingly recognised, however, no study has examined postoperative weight loss or its clinical relevance in these relatively thin patients. This study aimed to assess perioperative nutritional status as well as clinically severe involuntary weight loss and its impact on outcomes in patients with AIS undergoing posterior spinal fusion (PSF). A further objective was to compare preoperative anthropometric measurements of the current AIS cohort with healthy controls. ⋯ This study demonstrated that clinically severe postoperative weight loss >10%, identified in almost one-third of this AIS cohort, was associated with significantly increased wound infection incidence. Early detection and prevention of severe postoperative weight loss in patients with AIS who undergo spinal fusion may be beneficial in reducing wound infection risk. This study confirms a body of literature indicating the significantly lower weight and BMI in patients with AIS compared with healthy controls.

Fenestration is the gold standard surgery for lumbar spinal canal stenosis in Japan. Several previous studies have analyzed the reoperation rates in large numbers of patients undergoing several surgical procedures such as laminectomy with or without instrumented spinal fusion; however, there have been few studies focusing solely on fenestration. The purpose of this study was to calculate the reoperation rates after fenestration using the survival function method. ⋯ Fenestration can be performed at low cost using standard spinal surgery equipments. The reoperation rates of this procedure were lower than previously reported for several other surgical procedures.

To compare patient outcomes and complication rates after different decompression techniques or instrumented fusion (IF) in lumbar spinal stenosis (LSS). ⋯ As already demonstrated in the literature, decompression in patients with LSS is a very effective treatment. Despite better patient outcomes after laminectomy in combination with IF, caution is advised due to higher rates of surgical and general complications and consequent required measures. Based on the current study, laminotomy or laminectomy, rather than hemilaminectomy, is recommendable for minimum relevant pain relief.
