Application of dual-trajectory screws in revision surgery for lumbar adjacent segment disease: a finite element study

Journal of Orthopaedic Surgery and Research, 2022
Background Advancements in medicine and the popularity of lumbar fusion surgery have made lumbar adjacent segment disease (ASDz) increasingly common, but there is no mature plan for guiding its surgical treatment. Therefore, in this study, four different

Eye movement patterns during the recognition of three-dimensional objects: Preferential fixation of concave surface curvature minima [PDF]

, 2012
This study used eye movement patterns to examine how high-level shape information is used during 3D object recognition. Eye movements were recorded while observers either actively memorized or passively viewed sets of novel objects, and then during a ...

Internal fixation treatments for intertrochanteric fracture: a systematic review and meta-analysis of randomized evidence

Scientific Reports, 2015
The relative effects of internal fixation strategies for intertrochanteric fracture after operation remain uncertain. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to address this important issue.

Biomechanical efficacy of four different dual screws fixations in treatment of talus neck fracture: a three-dimensional finite element analysis

Journal of Orthopaedic Surgery and Research, 2020
Background Current there are different screws fixation methods used for fixation of the talar neck fracture. However, the best method of screws internal fixation is still controversial.
