概括

这项研究发现,二维参数,如两侧偏移指数和侧面带倾斜,在评估患有带脱的患者的带不良跟踪方面非常有效. 在全面扩展期间专注于这些可以简化手术前评估.

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.
生物力学生物力学

背景情况:

带错位是带脱位的一个常见问题,通常使用2D和3D成像技术进行评估.
准确地评估骨对齐对于有效的手术规划和患者的治疗结果至关重要.

研究的目的:

通过使用4D-CT扫描来研究骨倾斜和偏移之间的相关性.
为了比较2D和3D参数的诊断价值,在评估患有骨脱的患者的侧面骨错位.

主要方法:

4D-CT扫描被用于评估双截位移指数,侧面带倾斜,3D转移和3D倾斜在42名带脱位患者和42名对照组中.
3D转移和3D倾斜是根据骨的重心和与特定解剖平面相对的空间定向来定义的.

主要成果:

在患者和对照组之间观察到3D转移,3D倾斜,3D两侧偏移指数和横侧骨倾斜的显著差异,跨越各种膝盖屈曲角度 (p < 0.001).
3D偏移与3D倾斜有很强的相关性 (r=0.722,p<0.001),而两侧偏移指数与侧侧骨倾斜有很强的相关性 (r=0.697,p<0.001).
曲线下面面积 (AUC) 值表明,对2D (两侧偏移指数:0.964,侧侧骨倾斜:0.971) 和3D参数 (3D转移:0.931,3D倾斜:0.955) 的诊断准确度很高.

结论:

同时使用3D转移和3D倾斜可能不需要评估骨骨关节轴向对齐.
2D参数,特别是完全延伸的骨倾斜和转移,对于手术前评估骨失踪有价值,并且可能更简单.
临床医生应优先考虑动态检查,重点关注 patelar tilt 和patella dislocation 患者的完全延伸的移动.

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...
