Comparative Study
Comparison of hemiarthroplasty and total hip arthroplasty in elderly patients with displaced femoral neck fractures.
Objective This study was performed to compare the clinical and radiological outcomes of displaced femoral neck fractures (FNFs) treated with either hemiarthroplasty or total hip arthroplasty (THA) in elderly patients. Morbidity and mortality were also evaluated. Methods Twenty-two patients who underwent hemiarthroplasty and 16 patients who underwent THA for treatment of Garden type 3-4 FNFs from 2012 to 2015 were enrolled in this study. ⋯ Conclusion This study revealed no significant difference in the short-term clinical and radiological results between cementless hemiarthroplasty and THA in elderly patients with displaced FNFs. However, morbidity and mortality were associated with the presence of additional systemic diseases. THA is the preferred surgical technique in patients with displaced FNFs and low comorbidities.

Meta Analysis
Safety and efficacy of the oblique-axis plane in ultrasound-guided internal jugular vein puncture: A meta-analysis.
Objective This meta-analysis was performed to evaluate the safety and efficacy of the oblique-axis plane in ultrasound-guided internal jugular vein puncture. Methods We searched Embase, PubMed, the Cochrane Library, Web of Science, and China National Knowledge Infrastructure for relevant randomized clinical trials comparing the oblique axis with the short axis in ultrasound-guided internal jugular vein puncture. Results Five randomized clinical trials were included in this meta-analysis. ⋯ No significant difference was found in the first-pass success rate between the oblique-axis group and short-axis group. Additionally, there were no significant differences in the puncture success rate or number of attempts required between the two groups. Conclusion Ultrasound-guided internal jugular vein puncture using the oblique-axis plane reduced the risk of arterial puncture, but no difference was found in the first-pass success rate, puncture success rate, or number of attempts required.
