概括
军人新兵的骨压力损伤 (BSI) 与骨密度或微观架构无关. 训练负载和特定的军事角色,如降落团,是BSI的关键风险因素.
科学领域:
- 整形外科 整形外科 整形外科
- 运动医学 运动医学
- 军人卫生保健 军人卫生保健
背景情况:
- 脊椎微型架构对骨强度至关重要,但其对年轻健康成年人骨压伤 (BSI) 风险的具体贡献尚不清楚.
- 了解BSI的内在风险因素对于防止在苛刻的体育训练中受伤至关重要.
研究的目的:
- 研究骨微架构,体积骨矿物质密度 (vBMD) 和几何与英国陆军男步兵新兵下肢骨应力损伤 (BSI) 的发生率之间的关联.
- 在接受基础培训的高风险人群中确定BSI的内在和外在预测因素.
主要方法:
- 高分辨率的外围定量计算断层扫描 (HR-pQCT) 用于在训练第一周期间在201名男步兵新兵中评估部vBMD,几何和微观架构.
- 采用二进制逻辑回归分析来确定基线测量和通过MRI诊断的下肢BSI之间的关联.
- 共同变量包括年龄,体重,瘦身量,身高,维生素D水平,有氧健身 (2.4公里跑步时间) 和肌肉强度/功率.
主要成果:
- 20名新兵 (10.0%) 被诊断为下半身BSI.
- 在受伤前的参与者表现出下皮层面积,硬度和估计的故障负载.
- 然而,在对共变量进行控制后,部vBMD,几何和微观架构与BSI发生率没有显著的关联.
- 与线路步兵 (OR 9.3) 相比,降落兵团的风险更高,2.4公里的跑步时间更差 (OR 1.06).
结论:
- 内在因素,特别是超偏距 density密度,几何形状和微观架构,似乎不是这个队列中下体BSI的主要预测因素.
- 降落团中显著更高的BSI风险表明,训练负载和人口特异性风险因素比内在骨特征更有影响力.
- 未来的伤害预防策略应该考虑培训的强度和特定的职业需求.

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...

Bones of the Lower Limb: Tibia and Fibula
3.8K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Bone Disorders
3.7K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Compact Bone
11.9K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
