Comparative Study Observational Study
Preservation of Deep Cervical Extensor Muscle Volume: Comparison between Conventional Open-Door and Muscle Preserving Laminoplasty Approaches in the Same Patients.
Surgical laminoplasty techniques have been developed to reduce cervical kyphosis and postoperative axial neck pain and preserve the posterior cervical extensor muscles. We compared a unilateral conventional open approach (OA) and a contralateral muscle preserving approach (MPA) for laminoplasty in the same patients to determine differences in the preservation of the posterior cervical muscles after the 2 approaches. ⋯ MPA was effective in preserving the volume of deep cervical extensor muscles and helping minimize postoperative musculoskeletal complications. In addition, muscle preservation was more effective at the C3-4 level.

Observational Study
Evaluation of the Accuracy and Reliability of a Smartphone Stereotactic Coordinates Checking App.
Surgical assistance applications for smartphones have the potential to be used in daily practice; however, regular reviews of these tools are required. StereoCheck (Mevis, São Paulo, São Paulo, Brazil) is a mobile application (app) designed to compute stereotactic coordinates as a checking tool. The present study evaluated the accuracy and reliability of the StereoCheck app. ⋯ StereoCheck showed satisfactory accuracy and reliability. The use of photographs to compute the coordinates could lead to a significant decrease in the accuracy of the app.

Multicenter Study Observational Study
Risk factor for poor outcome of the elderly patients with aneurysmal subarachnoid hemorrhage based on the post hoc analysis of modified WFNS study.
There is currently no precise guide for the treatment and management of elderly patients with aneurysmal subarachnoid hemorrhage (aSAH). Thus, the aim of this study was to clarify the factors of poor outcome and mortality in elderly patients with aSAH. ⋯ The mWFNS scale is a useful prognostic predictor for both non-elderly and elderly patients with aSAH. Elderly male patients with aSAH presenting with severe vasospasm should be managed more carefully.

Multicenter Study
Full-endoscopic removal of lumbar juxtafacet cysts: a prospective multicentric study.
Lumbar juxtafacet cysts are benign lesions that grow at the level of facet joints or within neighboring structures. Recently, there is an ongoing trend toward less invasive procedures for treating degenerative spine diseases. Here we report a multicenter study of full-endoscopic surgery for juxtafacet cyst removal. ⋯ Full-endoscopic surgery is feasible and safe for juxtafacet cyst removal. Our results are consistent with findings from recent full-endoscopic and series, with outcomes overlapping those reported for open or tubular techniques.

Currently, it remains controversial about guidelines for the application of low-molecular-weight heparin (LMWH) in patients with acute ischemic stroke (AIS). Therefore this meta-analysis was carried out, aiming to systematically investigate the short-term and long-term safety and efficacy of LMWH in AIS patients. ⋯ To sum up, on the basis of limited studies available currently, the early use of LMWH in AIS patients aged older than 70 years should be cautious because it may increase the risk of all-cause mortality. For patients younger than 70 years old, the early use of LMWH significantly reduces the short-term risk of DVT, but there is no significant relationship in the long term. In terms of DVT prevention, enoxaparin and danaparoid are probably more effective. Nonetheless, more future randomized controlled trials are warranted to verify and support this conclusion.
