- 医疗成像医学成像
背景情况:
- 在MRI上发现的急性带脱的发现可以随着时间的推移而消失.
- 慢性骨关节骨不稳定性需要额外的诊断标志物超出最初的MRI发现.
研究的目的:
- 在MRI上识别和定义中间侧三角形 (MPT).
- 评估MPT中断在慢性骨骨不稳定中的诊断效用.
主要方法:
- 追溯分析24个患有慢性骨骨不稳定的膝盖和48个对照膝盖.
- 在轴性PD脂肪坐标MRI扫描上MPT的定义.

01:16Bones 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...

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...
