概括

脑髓指甲断裂很罕见,但TFNA的断裂率比PFNA高. 需要进一步的研究来了解近端大腿骨骨折管理中的植入物疲劳失败.

科学领域:

整形外科手术整形外科手术
生物材料工程是生物材料的工程.
医疗器械分析医疗器械分析

背景情况:

脑髓指甲对于近端大腿骨骨折的内部固定以及其他复杂的骨状况至关重要.
植入物断裂是一种罕见的并发症,历史基准表明病例率低于1.3%.

研究的目的:

为了准确地确定和比较脑髓指甲骨折的发病率在一个大,孤立的患者队列.
为了评估各种脑髓指甲设计中断裂率的潜在差异.

主要方法:

一项回顾性队列研究分析了来自西澳大利亚第三级公共骨科医院 (2001-2017) 的植入数据.
数据与植入物技术和检索分析中心 (CITRA) 存储库连接,以识别破碎的植入物.

主要成果:

在3,882个植入的指甲中,记录了18个断裂,导致整体断裂比例为0.5%.
托罗坎特指甲固定先进 (TFNA) 的破损率为1.5%,明显高于其前身,近位大腿指甲反旋转 (PFNA) 的0.2% (p=0.002).
对于Gamma3和PFN假肢的断裂率分别为0.6%和0.7%.

结论:

与PFNA相比,TFNA显示报告的故障比例高于PFNA,超过了确定的基准.
对于近端大腿骨骨折的植入物选择需要考虑破裂率以及其他失败模式和患者诊断.
进一步调查植入物疲劳失败,考虑混变量是必不可少的.

Fractures: Bone Repair

Fractures: Bone Repair

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 procedure...
