Intramedullary and extramedullary fixation methods are widely used to treat unstable femoral intertrochanteric fractures, but the optimal surgical method remains controversial. The aim of this study was to estimate the outcomes of intramedullary fixation versus extramedullary fixation in treating unstable femoral intertrochanteric fractures. ⋯ Our meta-analysis of 11 prospective randomized controlled trials suggested: no obvious discrepancies were found in adverse events, operative time, blood transfusion, and hospital stay between intramedullary and extramedullary fixations. Given the better results of intramedullary fixation in terms of functional scores and blood loss, we recommend the intramedullary fixation technique in treating unstable femoral intertrochanteric fractures. Large multi-center RCTs, which focused on unstable femoral intertrochanteric fractures, are needed to evaluate the efficiency of alternative internal fixation strategies in the future.

The object of the present meta-analysis is to compare the effectiveness of transforaminal epidural steroid injection (TFESI) and interlaminar epidural steroid injection (ILESI) for treating patients with low back pain (LBP) secondary to lumbosacral radicular pain. ⋯ According to the results of meta-analysis, TFESI to manage LBP provides superior short term pain relief and equal functional improvement when compared to ILESI. It has not shown a statistically significant difference between both groups with regard to procedure frequency, surgery rate, and ventral epidural spread.

Review Meta Analysis
Adductor canal block provides better performance after total knee arthroplasty compared with femoral nerve block: a systematic review and meta-analysis.
The methods for pain control after total knee arthroplasty (TKA) vary and have been extensively studied in recent years. Femoral nerve block (FNB) is used as the standard method due to its effective pain control following TKA, but it may weaken the quadriceps strength. Adductor canal block (ACB) is a newly developing analgesic protocol with fast functional recovery and good pain control after TKA. A meta-analysis was conducted to try to find out if ACB is better than FNB in pain treatment and joint functional recovery after TKA. ⋯ ACB provide better ambulation ability, faster functional recovery and better pain control at rest after TKA compared to FNB. The use of ACB post TKA is worthy of being recommended to replace FNB as a standard analgesic protocol for pain treatment after TKA.

The goal of this article is to evaluate the efficacy and the safety of the percutaneous vertebroplasty (PVP) versus percutaneous kyphoplasty (PKP) in dealing with the osteoporotic vertebral compression fracture (OVCF). ⋯ Based on current evidence, PVP takes less time in the operation, while it has greater risk of cement leakage, was inferior in reducing Cobb angle in the long term and results in lower anterior vertebral body height after the surgery. For pain relief, which is the main desire of the patients, both procedures provide significant improvement in VAS and ODI pain scores. PVP is still an effective procedure.

Meta Analysis Comparative Study
Meta-analysis of randomised controlled trials comparing unipolar with bipolar hemiarthroplasty for displaced femoral-neck fractures.
Unipolar and bipolar hemiarthroplasty (HA) are used to treat displaced femoral-neck fractures. However, which type is best for treating displaced femoral-neck fractures in elderly patients remains a subject for debate. Our aim was to review randomised controlled trials to establish which type provides superior clinical outcome for this patient population. ⋯ Unipolar and bipolar HA achieved similar clinical outcomes in patients with displaced femoral-neck fractures.
