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.

描述（由申请人提供）：拟议的研究旨在开发和评估一种新的外固定器，该外固定器可以在疏散到专门设施的早期阶段更容易、更有效地应用，用于儿科重症监护和康复。在第一阶段研究期间，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）。测试将包括与美国军事医学（Hoffmann II）采用的外固定器相比的“易于应用”和固定稳定性测试。在新装置中，成对的针簇取代了穿透骨头的线或针。固定器将通过手动致动器应用于骨膜，无需在骨头上钻孔并打开髓管。新的固定器将有可能结合现有半销外固定器（不需要钻孔）和无销 AO 外固定器（Alonso 和 Regazzoni，1990；Cheung、Wong 和 Choi，2001）（不穿透髓管）的优点。研究人员推测，采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医采用的外部半针固定器（Hofmann II）的实用水平。该假设将在应用简易性和固定稳定性的比较研究中得到评估。如果一期研究的目标得以实现，将进行进一步的研究（二期），以验证早期应用外固定器的有效性。
