单边多平面可调式骨外固定器的设计及生物力学特点
Design and biomechanical characteristics of adjustable multi-plane unilateral external fixator
摘要
Abstract
BACKGROUND: Fracture patients after treated with damage control fixation, when needed a secondary fixation under conditionsimproved, another appropriate nail point for re -fixation is necessary, or complicated components is configured before fixation toadjust the original nail position.OBJECTIVE: To design a adjustable multi -plane unilateral external fixation device for opening extremities comminuted fracturefixation and secondary non-invasive reduction and fixation under abnormal medical conditions, and to detect biomechanics of thedevice.METHODS: Totally 24 femur specimens of the adult large pigs were prepared to construct 12 comminuted fracture models, thendivided into experimental group with self-installing adjustable multi -plane unilateral external fixation and control group withinstallation of AO external fixation. Biomechanical testing was done separately in axial, shear and rotary conditions.RESULTS AND CONCLUSION: There were no significant difference of anti -stress, anti-bending and anti-rotation in the experimentaland control groups. The adjustable multi -plane unilateral external fixation can install nail arbitrary for temporary reduction and fixationwithin 1/3 perimeter of the injured limb. When secondary fixation, original components can fix firmly without re-set screw.关键词
