概括

短茎部植入物显著改变大腿偏移和腿部对齐,而不是直茎的设计. 精确的规划对于短茎全关节整形术至关重要,以避免不良结果.

科学领域:

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

背景情况:

腿部偏移和腿部长度对于成功的全关节整形术 (THA) 是至关重要的.
假肢的设计和放置影响了这些参数和整体腿轴对齐.
了解这些影响对于优化THA患者的治疗结果至关重要.

研究的目的:

调查茎的设计和放置对THA的股骨偏移和腿轴的影响.
为了比较短茎与直茎假肢对腿部对齐的影响.
评估假肢定位和由此产生的腿轴变化之间的关系.

主要方法:

这是一项前性研究,涉及27名接受THA.治疗的患者.
双平面放射 (EOS) 与3D重建 (sterEOS) 进行手术前后评估.
使用3D重建和mediCAD软件分析腿部对齐参数.
短茎和直茎假肢组之间的比较.

主要成果:

与直茎THA相比,短茎THA导致股骨偏移的变化明显更大 (11.4比4.6毫米).
短茎植入导致腿的方向显著增加 (-1.4比-0.4°).
在短茎和直茎假肢之间,在近端大腿骨的位置上没有发现显著的差异.

结论:

假肢的设计,特别是短茎植入物,显著影响大腿偏移和腿部对齐.
短茎THA植入与更大的变异性有关,需要仔细的手术规划.
为了获得最佳的THA结果,必须避免手术内非生理学偏移变化和Varus偏差.

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...
