概括
骨形态与前交叉带 (ACL) 延伸在像跑步或跳跃这样的高要求活动中没有直接联系. 虽然一些骨特征与膝盖运动相关,但它们不能预测运动员的ACL应变.
科学领域:
- 整形外科 整形外科 整形外科
- 生物力学 生物力学
- 运动医学 运动医学
背景情况:
- 前十字带 (ACL) 损伤在运动员中很常见,骨形态被认为是导致的因素.
- 在强烈的体力活动中,特定的骨形状,膝关节运动 (动力学) 和ACL应变之间的准确关系尚未完全理解.
研究的目的:
- 调查之前与ACL损伤风险相关的骨形态特征和改变的膝盖动力学是否也预测了ACL延长.
- 在高需求的活动中分析这些关系:快速跑步和双腿跳跃.
主要方法:
- 19名健康的运动员在快速跑步和跳跃时接受了双平面放射.
- 用3D运动捕捉和验证的成像分析来测量膝盖动力学和ACL延长.
- 关键的骨特征,包括侧向后侧部斜率 (LPTS),中侧部平原 (MTP) 深度,以及侧侧大腿/部平原宽度比率 (LCAP/TPAP),通过MRI量化.
主要成果:
- 没有发现骨形态和ACL延伸或快速跑步时的动力学之间存在显著的关联.
- 在跳中,增加的骨旋转与更的LPTS和更深的MTP深度相关.
- 较大的前额转换与较浅的MTP深度和较大的LCAP/TPAP比率有关;然而,只有更深的MTP深度与脚上增加的ACL延长有关.
结论:
- 观察到骨形态与膝盖动力学之间的联系并不一定意味着在高需求的活动中预测ACL延长.
- 这些发现完善了我们对骨结构和ACL应变之间的复杂相互作用的理解.
- 这种知识可能有助于识别面临ACL损伤风险较高的运动员,并可能指导手术干预.

Bones of the Lower Limb: Femur and Patella
2.6K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Knee Joint
1.9K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Muscles that Move the Leg
1.9K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
