- 运动医学运动医学
背景情况:
- 腿直骨 (RF) 肌是联合前交叉带 (ACL) 和前侧带 (AL) 重建的潜在移植来源.
- 使用双链射频 (DRF) 用于ACL和单链射频 (SRF) 用于AL重建需要进一步的生物力学验证.
- 在ACL和AL重建方案中,RF肌移植的生物力学数据有限.
研究的目的:
- 为了生物机械地比较DRF移植与骨肌 (PT) 移植用于ACL重建.
- 为了生物机械地比较SRF移植与皮带 (ITB) 移植用于AL重建.
- 测试假设DRF移植属性与PT移植相似,SRF移植属性与ITB移植相似的假设.
主要方法:
- 使用8个新鲜冷的人类膝盖进行的受控实验室研究.
- 准备和测试四种移植类型:DRF,SRF,PT和ITB.
- 使用材料测试机器通过最终强度,弹性模量和最终拉伸应力来评估移植生物力学.
主要成果:

Bone Remodeling and Repair
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
Deformation of Member under Multiple Loadings
When a rod is made of different materials or has various cross-sections, it must be divided into parts that meet the necessary conditions for determining the deformation. These parts are each characterized by their internal force, cross-sectional area, length, and modulus of elasticity. These parameters are then used to compute the deformation of the entire rod.
In the case of a member with a variable cross-section, the strain is not constant but depends on the position. The deformation of an...
