概括
较小的半骨角 (MBA) 是主要前十字带 (ACL) 损伤的重要预测因素,独立于运动活动水平. 这一发现凸显了MBA作为ACL受伤风险的关键内在因素.
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:
- 阴囊骨角 (MBA) 是与主要前十字带 (ACL) 损伤有关的内在因素.
- 以前的研究并没有将MBA和其他内在因素的影响与运动活动水平等外在因素隔离开来.
研究的目的:
- 为了评估与初级ACL损伤相关的内在因素,控制体育活动水平.
- 测试MBA是ACL缺陷的一个重要因素的假设,无论体育活动.
主要方法:
- 一项涉及143个膝盖与ACL损伤和143匹配的对照膝盖的横截面研究.
- 评估患者的身高,体重,BMI,侧部和中部后部部斜率角度 (LPTSA,MPTSA),MBA和相对后部倾斜角度 (RPIA).
- 后勤回归和接收器运行特征 (ROC) 曲线分析以确定显著因素和截止值.
主要成果:
- 在ACL损伤组中观察到较低的MBA (22.3°与29.1°) 和RPIA,以及较高的LPTSA (7.3°与5.0°) 和MPTSA (P < .001).
- 在逻辑回归中,MBA (OR,0.645;P < .01) 和LPTSA (OR,1.3;P < .001) 是ACL损伤的显著独立预测因素.
- 一个MBA切线值25.2°显示了76.2%的灵敏度和83.9%的特异性预测ACL损伤 (AUC,0.88).
结论:
- 较低的半骨角 (MBA),特别是低于25.2°,是主要的ACL损伤的最重要的独立预测因素.
- 即使在控制体育活动水平的差异之后,这种关联仍然很重要.
- MBA是关键的内在解剖学因素,有助于ACL受伤的风险.

Bones of the Lower Limb: Femur and Patella
4.8K
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

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...

Ankle Joint
2.8K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
