Review Meta Analysis
The association between changes in multifidus muscle morphology and back pain scores following discectomy surgery for lumbar disc herniation: a systematic review and meta-analysis.
To evaluate the impact of discectomy on back muscles (e.g. multifidus muscle (MM)) morphology in patients with lumbar disc herniation (LDH) following discectomy surgery, address the association of back muscles morphology with pain score preoperatively and post-operatively, and investigate the relationships between the changes from pre- to post-operative back muscles measurements and pain score (primary outcome) and disability score (secondary outcome) change following discectomy if any. ⋯ The results of this study found very low-quality grade evidence for an association between higher reduction of CSA in MM and less reductions of back pain scores following discectomy surgery for patients with LDH. Due to the heterogeneity and methodological limitations, further studies will improve understanding and aid preoperative counselling.

Meta Analysis
Causal effects of psychosocial factors on chronic back pain: a bidirectional Mendelian randomisation study.
Risk factors for chronic back pain (CBP) may share underlying genetic factors, making them difficult to study using conventional methods. We conducted a bi-directional Mendelian randomisation (MR) study to examine the causal effects of risk factors (education, smoking, alcohol consumption, physical activity, sleep and depression) on CBP and the causal effect of CBP on the same risk factors. ⋯ Fewer years of schooling, smoking, greater alcohol consumption, and major depressive disorder increase the risk of CBP. CBP increases the risk of greater alcohol consumption and smoking.

Review Meta Analysis
Can prophylactic negative pressure wound therapy improve clinical outcomes in spinal fusion surgery? A meta-analysis.
Recently negative pressure wound therapy (NPWT) is increasingly being prophylactically used to prevent wound complications in various types of surgeries, but its role in spinal fusion surgery was less well established. This study aimed to evaluate the efficacy of prophylactic NPWT (PNPWT) usage in spinal fusion surgery. ⋯ The current evidence suggested PNPWT could effectively reduce postoperative surgical site infection, but it had no significant benefit on reducing the incidence of wound dehiscence, overall wound complication, readmission and reoperation.
