Meta Analysis Comparative Study
Comparison of unilateral versus bilateral pedicle screw fixation in lumbar interbody fusion: a meta-analysis.
This is a meta-analysis to compare the clinical results between unilateral and bilateral pedicle screw (PS) fixation in lumbar interbody fusion. ⋯ In our meta-analysis, we found that unilateral PS fixation in lumbar fusion was as effective as bilateral PS fixation for lumbar degenerative diseases without major instability, no significant difference was found in hospital time, fusion rate and screw complications. In terms of operative time and blood loss, unilateral PS fixation even produced better results.

Randomized Controlled Trial
Treatment of cervical disc herniation through percutaneous minimally invasive techniques.
The goal of this study is to compare the therapeutic effectiveness of percutaneous cervical discectomy, percutaneous cervical disc nucleoplasty, and a combination of the two for the treatment of cervical disc herniation and the effective stabilization of the cervical vertebral column. ⋯ Each group achieved good clinical outcomes with this safe, minimally invasive spinal surgery for the treatment of cervical disc herniation. In addition, no postoperative risk of cervical instability was found.

Haemangiomas are very frequent benign spinal tumours. However, pure epidural location is extremely rare. At present, only 52 cases have been reported in the literature during the last 10 years. We proposed to analyse clinical and radiological features of this rare entity treated in a tertiary care centre over the last 10 years. ⋯ Epidural haemangiomas are extremely rare spinal lesions. They may mimic more common spinal tumours clinically and radiologically. The usual treatment is gross total resection confirming the diagnosis histologically.

The rabbit posterolateral intertransverse spine arthrodesis model has been widely used to evaluate spinal biologics. However, to date, the validity and reproducibility of performance of iliac crest bone graft, the most common and critical control group, has not been firmly established. We evaluated original research publications that utilized this model, identified which experimental conditions affected fusion rates, and developed an algorithm to predict fusion rates for future study designs. ⋯ Although experimental conditions varied across studies, time point evaluation and autograft volume significantly affected fusion rates. Despite some variability demonstrated across certain studies, we demonstrated that when the time point and volume of autograft were controlled for, the iliac crest control group of the rabbit posterolateral spinal arthrodesis model is both reliable and predictably affected by different experimental conditions.
