Scoliosis is a three-dimensional deformity of the spine that can lead to a series of physical and psychological problems. Appropriate controlling forces should be applied to prevent the curve's progression and even correct the deformity. The aims of this study were to develop a biomechanical model that can quickly estimate the optimal positions and magnitudes of the controlling forces for treating scoliosis and to analyze the interaction between longitudinal traction and lateral forces. Based on the scoliotic curve information that was extracted and simulated from the computed tomography data of patients, a mathematical model of scoliosis was established via the Timoshenko beam theory. The model could be optimized to provide precise and effective treatment for patients with different scoliosis curve patterns. The relationship between the corrective force position, magnitude, and the treatment effect on scoliosis could be obtained using this model. This study provides a biomechanical theoretical basis for determining the magnitude, position, and sequence of applying controlling forces on spines for patients with scoliosis.
脊柱侧弯是一种脊柱的三维畸形，可导致一系列生理和心理问题。应施加适当的控制力以防止侧弯进展，甚至矫正畸形。本研究的目的是建立一个生物力学模型，该模型可以快速估计治疗脊柱侧弯的控制力的最佳位置和大小，并分析纵向牵引与侧向力之间的相互作用。基于从患者计算机断层扫描数据中提取和模拟的脊柱侧弯曲线信息，通过铁木辛柯梁理论建立了脊柱侧弯的数学模型。该模型可以进行优化，为不同脊柱侧弯曲线类型的患者提供精确有效的治疗。利用该模型可以得到矫正力位置、大小与脊柱侧弯治疗效果之间的关系。本研究为确定脊柱侧弯患者脊柱控制力的大小、位置和施加顺序提供了生物力学理论依据。
