BACKGROUND
Our aim was to examine how academic adult reconstructive surgeons have interpreted evidence on femoral head material in total hip arthroplasty (THA).
METHODS
A 16-question survey to evaluate attitudes toward ceramic and cobalt-chrome head use was emailed to 274 faculty at 42 US adult reconstruction fellowship programs.
RESULTS
With 116 respondents, the response rate was 42.2%. Faculty use ceramic heads 72.9% of the time. The most common reason why respondents do not use ceramic heads is cost (44.8%). Ninety-four percent of faculty have observed head-neck taper corrosion in cobalt-chrome on polyethylene THA, while 9.5% of faculty have observed head-neck taper corrosion in ceramic on polyethylene THA. Only 6.0% of surgeons have seen Biolox Delta ceramic fracture.
CONCLUSION
Adult reconstruction thought leaders are guided by evidence suggesting that with ceramic heads, taper corrosion and fracture are rare. Cost and personal experience also strongly influence their implant selection. Efforts to equalize cost of ceramic and cobalt-chrome heads may free surgeons to practice in a purely evidence-based fashion.
背景
我们的目的是研究成人重建外科医生如何解读全髋关节置换术（THA）中股骨头材料的相关证据。
方法
通过电子邮件向美国42个成人重建 fellowship 项目的274名教员发送了一份包含16个问题的调查问卷，以评估他们对陶瓷和钴铬合金股骨头使用的态度。
结果
116名受访者的回复率为42.2%。教员72.9%的时间使用陶瓷股骨头。受访者不使用陶瓷股骨头的最常见原因是成本（44.8%）。94%的教员在钴铬合金对聚乙烯的THA中观察到头颈锥度腐蚀，而9.5%的教员在陶瓷对聚乙烯的THA中观察到头颈锥度腐蚀。只有6.0%的外科医生见过Biolox Delta陶瓷骨折。
结论
成人重建领域的思想领袖受到证据的指导，表明使用陶瓷股骨头时，锥度腐蚀和骨折很少见。成本和个人经验也强烈影响他们的植入物选择。平衡陶瓷和钴铬合金股骨头成本的努力可能会使外科医生能够以纯粹基于证据的方式进行手术。
