Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

2.5K
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...

科学领域:

  • 整形外科手术 整形外科手术
  • 生物力学 生物力学
  • 骨关节炎的研究研究.

背景情况:

  • 开式高骨切除术 (OWHTO) 是膝关节关节炎的一种常见手术.
  • 在OWHTO期间过度纠正可能导致下骨和手术后膝盖疼痛.
  • 确定最佳的纠正角度对于成功的外科手术结果至关重要.

研究的目的:

  • 为了确定在OWHTO期间与症状的骨位置变化相关的膝关节静脉纠正的切断点.
  • 建立一个安全的校正范围,以尽量减少术后并发症.

主要方法:

  • 对124名接受双平面介质OWHTO治疗膝关节骨关节炎的患者进行了回顾性研究.
  • 手术前和后 (18个月) 的放射和CT成像.
  • 评估骨高度 (卡顿 - 德坎普斯,英萨尔 - 萨尔瓦蒂,布莱克伯恩 - 皮尔指数),骨骨关节指数,骨倾斜,以及WOMAC分数.

主要成果:

  • 观察到皮带指数的显著变化与不断增加的校正角度.
  • 骨高度,倾斜和骨骨指数显示出明显的变化超出了一定校正值.
  • 与A-F组相比,更大的校正角度 (G,H,I) 的组表现出明显较差的带指数变化和较低的WOMAC得分改善.

结论:

  • 骨的高度,倾斜和骨骨关节指数都受到骨折修复的程度的显著影响.
  • 校正角度的关键切线点被确定为12.5°至13.4°.
  • 超过这个范围的校正角度可以显著改变骨位置,可能导致术后骨关节疼痛.
