Review Meta Analysis
Evaluating outcomes of stand-alone anterior lumbar interbody fusion: a systematic review.
Stand-alone anterior lumbar interbody fusion (ALIF) is an effective surgical approach for selected spinal pathologies. It avoids the morbidity and complications associated with instrumented ALIF, such as plate fixation and the traditionally used posterior approach. Despite improved disc space visualization and clearance, the associated posterior instability and increased risk of nonfusion present major challenges to this approach. The integral cage design aims to address these challenges by providing the necessary stabilization through intracorporeal screws. However, there is limited and controversial data available for stand-alone ALIF and integral cage fixation. To our knowledge, this is the first systematic review to evaluate recent findings on outcomes of stand-alone ALIF devices to explore areas of controversy and identify directions for future research. ⋯ There is evidence for the efficacy and safety of stand-alone ALIF. However, the extent of improvement based on specific indications for surgery remains unclear. Further investigation utilizing more methodologically rigorous studies of long-term outcomes is necessary to address these issues.

Randomized Controlled Trial Comparative Study
Preoperative Planning of Lateral Entry Point is Necessary in Percutaneous Lumbar 5th Vertebroplasty.
To compare treatment outcomes and complications between the computer-assisted preoperative planning of lateral entry approach and the traditional approach for L5 percutaneous vertebroplasty. ⋯ Owing to the hemispherical morphology and convergent pedicle axis of the L5 vertebrae, a more lateral skin entry point and convergent angle of the puncture needle should be emphasized to reach the optimal point according to the preoperative assessment. The approach involving computer-assisted preoperative planning of the lateral entry point was associated with a higher rate of bilateral cement infiltration with fewer complications.

Randomized Controlled Trial
Accuracy of Varioguide frameless stereotactic system against Frame based stereotaxy: Prospective randomized single-centre study.
Frameless stereotactic brain biopsy systems are widely used today. VarioGuide (VG) is a relatively novel frameless system. Its accuracy was studied in a laboratory setting but has not yet been studied in the clinical setting. The purpose of this study was to determine its accuracy and diagnostic yield and to compare this with frame-based (FB) stereotaxy. ⋯ The VG system proved to be comparable in terms of the trajectory accuracy, rate of complications and diagnostic yield compared with the "gold standard" represented by the traditional FB stereotaxy for patients undergoing brain biopsy. VG is also better accepted by patients.

Review Case Reports
Unusual intra-parenchymal pontomedullary epidermoid cyst in a 2 year-old: case report and literature review.
Intrinsic brainstem epidermoid cysts are rare, benign, slow-growing lesions. Their eloquence precludes complete excision; however, subtotal resection often will result in prolonged or sometimes permanent relief of presenting symptoms and signs. We describe an unusual case and review the literature of this pathology in the pediatric population. ⋯ Our case, supported by the literature, shows that brain stem epidermoid cysts may have atypical radiologic characteristics and that near-total resection remains safe and can improve outcome.

Multicenter Study
Outcome of Endoscopic Transsphenoidal Surgery for Acromegaly.
Endoscopic transsphenoidal surgery has recently been introduced in pituitary surgery. We investigated outcomes and complications of endoscopic surgery in 2 referral centers in Korea. ⋯ Endoscopic transsphenoidal surgery for acromegaly presented high remission rates and a low incidence of endocrine deficits and complications. Regardless of surgical techniques, invasive pituitary tumors were associated with poor outcome.
