The Influence Mechanism of Screw Internal Fixation on the Biomechanics of Lateral Malleolus Oblique Fractures.
Int J Numer Method Biomed Eng
January 2025
It remains inconclusive about the stability and optimal fixation scheme of screw internal fixation for lateral malleolus oblique fractures in clinical practice. In this study, the effects of different screw internal fixation methods on the biomechanics of lateral malleolus oblique fractures were investigated. These efforts are expected to lay a theoretical foundation for the selection of internal fixation methods and rehabilitation training regimens in the treatment of lateral malleolus fractures.

- Ankle fractures are common, making up around 10% of all fractures, and can lead to malunion in 5-68% of cases, which can negatively impact the biomechanics of the ankle joint.
- A study used a 3D model based on CT scans to explore how small shifts in fracture fragments affect ankle joint performance and the impact of malunion in various ankle positions.
- Results indicated that malunion increases the ankle joint's contact area, with outward shifts having a more significant impact than backward shifts, potentially leading to osteoarthritis due to improper load distribution on ankle ligaments.
Article Synopsis
- - The study explores the dynamics of elliptical jets influenced by surface tension forces, which cause capillary instability independent of air effects in the Rayleigh regime.
- - It employs the Cosserat equation to analyze how fluid viscosity impacts jet behavior, presenting solutions that reveal complex roots linked to jet breakup, and introduces a spatial wave linked to an axis-switching phenomenon.
- - Experimental findings support the theoretical predictions regarding the axis-switching wavelength and the effects of viscosity, while also indicating that factors like orifice shape and specific dimensionless numbers affect instability growth rates.
