概括

在末期膝关节骨关节炎 (KOA) 中,靠近骨的下骨矿物质密度 (BMD),而不是股骨-骨差异,有助于中间骨崩. 这一发现澄清了KOA患者骨变形的机制.

科学领域:

整形外科整形外科整形外科
放射学放射学是一门学科.
生物医学工程生物医学工程

背景情况:

在末期膝关节骨关节炎 (KOA) 中,研究膝关节周围的骨矿物质密度 (BMD).
旨在澄清KOA患者形变形超过大腿变形的形变形机制.

研究的目的:

为了评估骨矿物质密度 (BMD) 和骨变形之间的关系,在骨末期膝关节骨关节炎 (KOA).
阐明在KOA患者的股骨变形相比,股骨变形更大背后的机制.

主要方法:

对193名末期KOA患者和经过全膝关节整形手术的关节对齐的患者进行了回顾性分析.
在手术前测量股骨部和总T分数 (DXA) 和远部股骨/近骨Hounsfield单位 (HU) (CT).
腿骨和骨之间的BMD (HU) 的比较,根据中间近端角 (MPTA) 分层.

主要成果:

靠近骨的HU低于距离大腿骨的HU (大腿骨侧面>大腿骨中间>大腿骨中间>大腿骨侧面).
2组 (MPTA < 85°) 与1组 (MPTA ≥ 85°) 相比,在股骨和骨中显示较低的T-score和HU.
两组之间没有观察到股骨-骨HU差异的显著差异.

结论:

在体末期KOA中,中骨的缩与较远大腿骨BMD相比,与下近端骨BMD有关.
中部骨缩受绝对BMD值的影响,而不是大腿骨和骨之间的BMD差异.

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...
