概括

在逆向全肩关节整形手术 (RTSA) 中,短腰干错位是常见的,与骨质无关. 手术前的患者解剖学,特别是部轴角 (NSA),影响着茎的对齐,这不会影响中期的功能结果.

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:

在逆向全肩关节整形手术 (RTSA) 中,短骨茎需要良好的近接骨质才能安全固定.
与标准或长茎相比,较短的茎可能会增加植入物错位的风险.

研究的目的:

调查区域骨质量是否影响RTSA中短部茎的错位.
确定骨质量,患者解剖学和植入物对齐之间的相关性.

主要方法:

对35例RTSA病例的回顾性审查,使用一个短曲部茎,部轴角度为132.5° (NSA).
靠近腰部骨质的质量,使用状管状性指数 (DTI) 进行评估.
干部对齐,以部轴轴与植入物干部轴之间的角度来衡量.

主要成果:

平均DTI为1.37±0.16;22名患者 (63%) 的骨质不佳 (DTI<1.4).
71%的部部件在RTSA后失调.
在DTI和失调之间没有发现相关性 (p=0.504),但在失调和手术前NSA之间存在强烈的相关性 (r=-0.47,p=0.004).
手术后的干部位置和错位与功能结果没有相关性 (p>0.05).

结论:

在RTSA中,短曲部茎的错位经常发生.
靠近腰部骨质的质量不佳不会影响干部错位.
手术前的NSA和部切割技术与术后的茎对齐有关.
中期功能结果不受干部错位的影响.

关键词:

Bones of the Upper Limb: Humerus

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
