摘要

In 2009, approximately 285,000 total hip replacements were performed in the United States. Many expect this number to continue climbing due to longer lifespans and the increasing number of people with arthritis. Early total hip replacements used ivory implants placed into a patient's hip to relieve pain.2 Dr. M.N. Smith-Petersen implanted a glass hemisphere over the femoral head in 1925. The glass wasn't sturdy and failed, but the idea of relieving a patient's hip pain through surgery flourished. In 1936, a new metal alloy called cobalt-chromium was developed and is still used today. Dr. Frederick Thompson and Dr. Austin Moore each developed hip prosthesis implants to treat fractured hips. Surgeons found that loose femoral stems caused pain and they questioned if hip implants could be "glued" into place. The combined efforts of these and other pioneers set the stage for British surgeon Dr. Sir |ohn Charnley's success.

Dr.史密斯—彼得森(Smith-Petersen)在1925年将玻璃半球植入股骨头上方。该玻璃虽然坚固但不合格,但通过手术缓解患者髋部疼痛的想法大行其道。 1936年,开发了一种新型金属合金,称为钴铬合金,至今仍在使用。弗雷德里克·汤普森(Frederick Thompson)博士和奥斯汀·摩尔(Austin Moore)博士各自开发了髋关节假体植入物,以治疗髋部骨折。外科医生发现股骨干松动会引起疼痛,他们质疑髋关节植入物是否可以“粘合”到位。这些和其他先驱者的共同努力为英国外科医生奥赫·夏恩利爵士的成功奠定了基础。
