概括
化 (TiN) 涂层植入物有助于在全膝关节整形术 (TKA) 植入物周围保持骨密度,比- (CoCr) 植入物更好. 这表明,TiN可能有助于在TKA后维持周围假肢骨库.
科学领域:
- 整形外科手术 整形外科手术
- 生物材料科学是生物材料的科学.
- 放射学 放射学是一门学科.
背景情况:
- 在全膝关节整形术 (TKA) 后,植入物材料和周围假肢骨矿物质密度 (pBMD) 之间的关系尚不清楚.
- 植入物周围的骨损失可能会影响长期的TKA结果.
研究的目的:
- 为了研究TKA后的pBMD的变化.
- 为了比较化 (TiN) 涂层和化 (CoCr) 植入物材料之间的pBMD变化.
主要方法:
- 一项前性,匹配对,病例控制研究,涉及29名接受双边TKA的患者.
- 患者在每个膝盖中都接受了TiN涂层或CoCr植入物.
- 周围假肢骨矿物质密度 (pBMD) 在基线,手术后1年和2年使用双能X射线吸收计测量;估计的pBMD (pBMDe) 通过X射线图评估在>2年.
主要成果:
- 在手术后2年,pBMD在两个小组中均显著降低,在中侧骨转移和前侧远侧股骨.
- 与化 (TiN) 组相比,- (CoCr) 组在近接骨中表现出更大的pBMD减少.
- 估计的pBMD (pBMDe) 在TiN组显著更高,在7年后的前远大腿骨上.
结论:
- 膝关节全关节整形术 (TKA) 后,无论植入物材料如何,周围假肢骨矿物质密度 (pBMD) 在特定区域下降.
- 与- (CoCr) 植入物相比,化 (TiN) 植入物在某些部和大腿部区域显示出优异的骨保存.
- 在TKA之后,TiN植入物似乎有利于保持周围假肢骨库存.

01:18The Bone Matrix
3.2K
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in...

01:16Bones 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...

01:23Knee 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...
