概括
下部计算机断层扫描 (CTHU) 预测在开放缩减和内部固定 (ORIF) 后,关骨骨折固定失败. 这一发现有助于外科医生在ORIF和初级关节整形之间做出选择.
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.
- 生物医学工程 生物医学工程
背景情况:
- 靠近骨骨折很常见,开放式减轻和内部固定 (ORIF) 是标准的治疗方法.
- 需要修复手术的固定失败是一个重要的并发症.
- 骨密度可以通过计算机断层扫描测量Hunsfield单位 (CTHU),可能会影响ORIF的成功.
研究的目的:
- 为了调查状的CTHU是否预测近接骨骨折中的ORIF失败.
- 确定CTHU <160 HU是否与关节塑形术的修订率增加有关.
主要方法:
- 追溯的队列研究,对135名近腰骨折患者进行了20年的ORIF治疗.
- 在手术前进行了状的CTHU测量.
- 根据患者是否需要修改关节管整形手术,对患者进行了分析.
主要成果:
- 需要修改的患者与没有修改的患者相比,平均CTHU (110.9 HU) 显著降低 (170.5 HU).
- CTHU <160 HU是ORIF失败的独立风险因素,增加了修订风险的3倍.
- 较低的CTHU与2部分和3部分骨折的更高修订率相关.
结论:
- 状的CTHU<160 HU是近接骨骨折中ORIF失败的独立预测因子.
- 这种测量可以帮助外科医生在ORIF和初级关节整形之间做出决定,以获得更好的患者结果.
- 机会主义CTHU评估可以指导复杂骨折管理中的手术决策.

01:29Bone Disorders
5.0K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:27Fractures: Bone Repair
5.0K
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...

01:19Bones of the Upper Limb: Humerus
6.9K
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...
