概括

膝关节骨关节炎 (OA) 与近腹骨的骨密度不均有关. 较高的中间骨密度和较大的区间差异与OA有关,这表明风险分层的潜在成像标志物.

科学领域:

放射学放射学是一门学科.
整形外科整形外科整形外科
生物医学成像技术生物医学成像技术

背景情况:

靠近骨骨密度的分区失衡可能会导致膝关节骨关节炎 (OA) 的进展.
使用CT衍生的霍恩斯菲尔德单位 (HU) 对这种不平衡的定量成像仍未得到充分研究.
这项研究调查了近端骨密度和膝盖OA之间的关联.

研究的目的:

为了研究区间近端骨密度和膝盖OA之间的关联.
评价CT衍生的霍恩斯菲尔德单位 (HU) 作为膝盖OA骨密度的度量.
探索这些措施在识别OA时的诊断性能.

主要方法:

在753个膝盖 (238个OA,515个非OA) 进行了回顾性横截面研究,使用CT,膝盖放射和ortoradiogram.
在中位平原,横位平原和中央转化中测量了HU值.
通过逻辑回归评估了与OA的关联,并通过ROC分析评估了诊断性能.

主要成果:

与非OA膝关节相比,OA膝关节显示出较低的近端部HU值.
较高的中间HU值 (OR每100HU: 1.49) 和较大的中间到侧面HU差异 (OR: 1.27) 与OA相关.
中间HU值具有中等的区分力 (AUC=0.682),而中间与侧面差异具有有限的独立性能 (AUC=0.553).

结论:

患有OA的膝盖表现出不对称的近道骨重塑,具有更高的中间亚粒体密度和更低的甲基细胞骨密度.
来自CT的HU值和隔间差异可以作为OA风险分层的探索性放射学标记.

Bone Disorders

Bone Disorders

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...

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

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

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...
