■车道板是最早广泛使用的骨板之一,在二十世纪的头几十年中使用。在这里,我们介绍了Lane平板上的检索分析结果,并回顾了这些板块的历史。1938年,我们的病人用Lane板对她的股骨进行了电镀。她出现了坐骨神经麻痹,当年晚些时候由爱荷华大学的ArthurSteindler博士进行手术管理。她的股骨愈合了,她的神经恢复了,她做得很好,直到2020年,在94岁的时候,她向爱荷华大学展示了一个排水窦,似乎与盘子相通。她进行了冲洗和清创,并清除了硬件。盘子被切开了,并对其组成和结构进行了表征。
■我们检索了1938年患者存档病历的硬拷贝,详细记录了Steindler博士的治疗。使用扫描电子显微镜(SEM)分析板以表征板的表面。从板上取下横截面,并且使用能量色散X射线光谱法(EDS)确定合金的组成。对有关早期电镀技术的文献进行了回顾。
我们的患者从手术中恢复,很快恢复到基线健康状态。术中培养培养痤疮梭菌。对板表面的分析显示出明显的腐蚀,并且在SEM上看到的晶体结构表明易于腐蚀的强合金。用EDS对横截面的分析表明,合金含有94.9%的铁,1.7%铝,1.2%铬,和1.1%的锰。
■Lane板块于1907年左右由WilliamArbuthnotLane爵士推出,一位英国外科医生,并且是最早广泛使用的断裂电镀设备之一。鉴于该患者可能是最后接受Lane板治疗的患者之一,这可能是进行这种检索分析的最后机会。证据等级:IV。
UNASSIGNED: The Lane plate was one of the first widely used bone plates, utilized in the first decades of the twentieth century. Here we present the results of a retrieval analysis on a Lane plate, and a review of the history of these plates. Our patient underwent plating of her femur with a Lane plate in 1938. She developed a sciatic nerve palsy, managed surgically later that year by Dr. Arthur Steindler at the University of Iowa. Her femur healed, her nerve recovered, and she did well until 2020, at age 94, when she presented to the University of Iowa with a draining sinus that appeared to communicate with the plate. She underwent irrigation and debridement with hardware removal. The plate was sectioned, and its composition and structure characterized.
UNASSIGNED: We retrieved hard copies of the patient\'s archived medical records from 1938, which document in detail the treatments performed by Dr. Steindler. The plate was analyzed using scanning electron microscopy (SEM) to characterize the surface of the plate. A cross section was taken from the plate, and the composition of the alloy was determined using energy dispersive x-ray spectroscopy (EDS). A review of the literature surrounding early plating techniques was conducted.
UNASSIGNED: Our patient recovered from her surgery and soon returned to her baseline state of health. Intraoperative cultures grew C. acnes. Analysis of the surface of the plate demonstrated significant corrosion, and the crystal structure seen on SEM suggested a strong alloy that is prone to corrosion. Analysis of the cross section with EDS demonstrated an alloy containing 94.9% iron, 1.7% aluminum, 1.2% chromium, and 1.1% manganese.
UNASSIGNED: The Lane plate was introduced around 1907 by Sir William Arbuthnot Lane, a British surgeon, and was one of the first widely used devices for the plating of fractures. Given that this patient was likely one of the last to be treated with a Lane plate, this may be the final opportunity for such a retrieval analysis. Level of Evidence: IV.
