概括

逆侧关节炎显著影响关节整形术后的骨盆倾斜 (PT) 变化. 了解这些变化对于优化关节置换患者的植入物定位和手术结果至关重要.

科学领域:

整形外科手术整形外科手术
放射学放射学是一门学科.
生物机械工程生物机械工程

背景情况:

骨盆倾斜 (PT) 影响关节的前转和倾斜.
术前和术后的放射分析对于评估PT变化至关重要.
逆侧部疾病可能会影响部关节整形术后的PT调整.

研究的目的:

为了研究 contralateral 关节炎对关节整形术 (THA) 后的骨盆倾斜 (PT) 变化的影响.
为了比较正常,关节炎或被替换的逆侧部的患者的PT变化.

主要方法:

对193个THA初级病例的回顾性审查.
从前后视图使用特定的放射测量计算骨盆倾斜 (PT).
反侧部的分类为正常,关节炎 (Tönnis等级3/4),或被替换.

主要成果:

在研究组中观察到手术后PT变化的显著差异 (P < .01).
患有正常逆侧部的患者平均PT变化为-5.2° (绝对平均差异为7.6°).
关节炎和被替换的逆侧部表现出较小的绝对平均PT差异 (分别为5.0°和4.3°).

结论:

逆侧部病理显著改变术后的骨盆倾斜.
这些PT变异对于在THA.期间实现最佳的acetabular杯放置有影响.
考虑逆侧部的状态对于THA手术规划至关重要.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
