Finite element analysis of new headless compression supporting screw for the treatment of unstable femoral neck fracture.

Background: Femoral neck fracture is an unsolved challenge in orthopedics. The complication rate in particular is high. There remains a lack of consensus on the optimal choice of internal fixation for unstable femoral neck fracture.

Three-Dimensional Analysis of the Curvature of the Femoral Canal in 426 Chinese Femurs.

Purpose: The human femur has long been considered to have an anatomical anterior curvature in the sagittal plane. We established a new method to evaluate the femoral curvature in three-dimensional (3D) space and reveal its influencing factors in Chinese population.

Methods: 3D models of 426 femurs and the medullary canal were constructed using Mimics software.

[Treatment of clavicular fractures using intramedullary nailing or K-wire versus plating fixation: a meta-analysis].

Objective: TFo compare the efficacy and complications rate of intramedullary (IM) nailing or K-wire versus plating fixation for clavicular fractures.

Methods: Pubmed, Embase, Cochrane Library databases, CNKI, VIP and Wangfang databases were searched to find all randomized or quasi-randomized controlled trials of clavicle fractures using plating versus IM nailing or K-wire. The methodologic quality of the studies was assessed.
