项目摘要

DESCRIPTION (provided by applicant): The proposed study is aimed at developing and evaluating a new external fixator, that could be more easily and effectively applied at the early stages of evacuation to specialized facilities, for pediatric critical care and rehabilitation. During the Phase I study, a newly developed external double-needle Iizarov fixator (Pitkin and Gritsanov, 2005) will be tested and further developed. Testing will include "ease-to-apply" and stability of fixation tests, as compared to the external fixator adopted by US Military medicine (Hoffmann II). In the new device, clusters of paired needles replace wires or pins penetrating the bone The fixator is to be applied to the bone periosteum by manual actuators, without drilling the bone and opening of the medullary canal. The new fixator will potentially combine the advantages of the existing half-pin external fixators, which don't require drilling, and the pinless AO external fixator (Alonso and Regazzoni, 1990; Cheung, Wong and Choi, 2001), which doesn't penetrate the medullar canal. The Investigators hypothesize that with the newly developed double-needle fixator, the stability of fixation and simplicity of operating the apparatus will surpass the level of practicality of the external half-pin fixator (Hofmann II) adopted by the US Military Medicine. The hypothesis will be evaluated during the comparative studies on the ease of application and the stability of fixation. If this aim of the Phase I study is achieved, the further study (Phase II) will be conducted to verify the effectiveness of the early application of external fixation.

说明(申请人提供)：拟议的研究旨在开发和评估一种新的外固定器，它可以在撤离到专门设施的早期阶段更容易和有效地应用于儿科危重护理和康复。在第一阶段研究中，将测试和进一步开发新开发的外部双针Iizarov固定器(Pitkin和Gritsanov，2005)。与美国军事医学(Hoffmann II)采用的外固定器相比，测试将包括固定测试的“易用性”和稳定性。在新的装置中，成对的针束取代了穿透骨骼的金属丝或钉子。固定器将通过手动执行器应用于骨膜，而不需要钻骨和打开髓管。新的固定器可能会结合现有的半钉外固定器和无针AO外固定器的优点(Alonso和Regazzoni，1990；Cheung，Wong和Choi，2001)，前者不需要钻孔，后者不会穿透髓管。研究人员推测，使用新开发的双针固定器，固定的稳定性和操作的简单性将超过美国军事医学采用的外半针固定器(Hofmann II)的实用水平。这一假说将在关于固定的易用性和稳定性的比较研究中进行评估。如果达到第一阶段研究的目标，将进行进一步的研究(第二阶段)，以验证早期应用外固定架的有效性。
