概括
修改后的近端关节锁定板 (PHILOS) 提供了与远端关节轴骨折的外关节远端关节板 (EADHP) 相当的生物机械稳定性. 这种前涂层技术可以减少诸如辐射神经损伤和皮肤刺激等并发症.
科学领域:
- 整形外科手术 整形外科手术
- 生物力学 生物力学
- 有限元素分析的研究.
背景情况:
- 除关节外的远端骨板 (EADHP) 是远端骨轴骨折 (DHSF) 的常见病例.
- 由于辐射神经受伤和皮肤刺激,关于EADHP手术方法,固定和植入物放置存在争议.
- 采用修改后的近端部锁板 (PHILOS) 进行前部板是拟议的替代方案,但其生物力学性能需要进一步进行定量评估.
研究的目的:
- 量化比较用EADHP进行后面涂层的生物力学性能与用DHSF修改的PHILOS进行前面涂层的生物力学性能.
- 通过有限元分析 (FEA) 在各种负载条件下评估植入物稳定性.
主要方法:
- 用有限元分析 (FEA) 模拟和比较生物机械性能.
- 模拟评估了两个技术在轴向,曲和变量力负载条件下的稳定性.
主要成果:
- EADHP和PHILOS都表现出足够的生物力学性能和稳定性.
- 修改后的PHILOS实现了与EADHP可比的固定稳定性.
- 菲洛斯的固定只需要四个锁定螺丝在30毫米的距离上方的olecranon fossa.
结论:
- 修改后的PHILOS板块提供了与DHSF固定的EADHP可比的生物机械稳定性.
- 用修改后的PHILOS进行前部涂层是一种可行的替代方案,可能减轻与EADHP相关的辐射神经损伤和皮肤刺激风险.

3.3K
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...

3.3K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
