概括

在下冠状腺骨折固定后的微板骨折是罕见的. 布鲁克斯症和吸烟引起的金属疲劳导致了患有状部骨折的患者的这种罕见并发症.

科学领域:

口腔和牙面部外科手术
生物材料科学生物材料科学
整形外科手术整形外科手术

背景情况:

用于下骨骨折的内部固定所使用的迷你板的骨折是一种不常见的并发症.
之前的研究表明,发病率很低,约为2.6%.

研究的目的:

报告一个罕见的案例,在 mandibular condylar 骨折的内部固定后,出现了型小板骨折.
为了调查在这种特定情况下,迷你板故障的潜在原因.

主要方法:

一个54岁的女性患者的病例报告,她患有右侧状部骨折,并使用迷你板进行治疗.
手术后的放射性评估和扫描电子显微镜 (SEM) 的破碎的小板.
患者病史包括饮食,吸烟和像 Bruxism 这样的功能障碍习惯.

主要成果:

在手术后5个月发现了一个迷你板的骨折.
在SEM分析中,发现了纹线,表明金属疲劳骨折.
患者报告的乳头发和不坚持戒烟被确定为导致因素.

结论:

金属疲劳可能是型小板骨折的可能原因,尤其是在下骨骨折固定时,与患者相关的因素,如乳头和吸烟相结合时.
坚持术后的治疗方案和对功能习惯的管理对于长期的植入物存活至关重要.

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...
