简要总结
The study will be conducted to investigate the effects of electrical charges (flexoelectric effect) & mechanical brachioradialis muscle bending force on the displacement and strain of fracture gap on children with Distal radius greenstick fracture via finite element method.
详细描述
Distal radius fractures are common fractures and highly prevalent especially in children, due to skeletal immaturity. They may present as greenstick fractures; due to falling on the outstretched hand during sporting events.
This type of fracture causes deformation and angulation on the cortex layer of bone, while the other side remains intact due to the higher proportion of collagen and flexibility in immature bones, making them more prone to bending rather than breaking completely.
The biomechanical environment plays a dominant role in the process of fracture healing.
It controls the communication network of biological tissues and triggers the complex proliferation process.
This mechanical load is originated from muscle contraction along the axis of bone, which improves the healing process and accelerates the earlier return to weight bearing.

结局指标
主要结局
Displacement and strain of fracture gap
时间窗: Followed up by x-ray weekly for 3:6 weeks.
The angle of fracture displacement will be measured and followed up by x-ray weekly for 3:6 weeks. A reference line will be determined between proximal and distal points of the radial styloid with the fracture inclination line to identify the radial inclination angle (normal angle 22 -23 degrees).
