Biomechanical and clinical testing of an atlantoaxial posterior fixation device.
The authors tested an internal fixation device to maintain the atlas and axis in an anatomic relationship while fusion occurs. The device should also facilitate intraoperative reduction of any residual anterior atlantoaxial subluxation. The device should allow the use of cancellous rather than cortical bone graft.
Previous techniques of atlantoaxial fusion were not universally successful, and the quality of reduction was assessed infrequently.
Biomechanical testing of the fixator and clinical use in two "problem" patients requiring atlantoaxial fusion.
Biomechanical testing indicated the device should be successful. Clinical testing was successful.
The new fixator facilitates posterior atlantoaxial fusion in an anatomical position.
寰枢椎后路固定装置的生物力学与临床测试。
作者测试一种内固定装置，在融合发生时保持寰椎和枢椎处于解剖学关系。该装置还应便于术中对任何残留的寰枢椎前脱位进行复位。该装置应允许使用松质骨而非皮质骨移植。
以往的寰枢椎融合技术并非普遍成功，且很少评估复位质量。
对该固定器进行生物力学测试，并在两名需要寰枢椎融合的“疑难”患者中进行临床应用。
生物力学测试表明该装置应能成功。临床测试取得成功。
新型固定器有助于在解剖位置实现寰枢椎后路融合。
