Abstract

BACKGROUND:

Fracture patients after treated with damage control fixation, when needed a secondary fixation under conditions improved, another appropriate nail point for re-fixation is necessary, or complicated components is configured before fixation to adjust the original nail position.

OBJECTIVE:

To design a adjustable multi-plane unilateral external fixation device for opening extremities comminuted fracture fixation and secondary non-invasive reduction and fixation under abnormal medical conditions, and to detect biomechanics of the device.

METHODS:

Totally 24 femur specimens of the adult large pigs were prepared to construct 12 comminuted fracture models, then divided into experimental group with self-installing adjustable multi-plane unilateral external fixation and control group with installation 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 experimental and control groups. The adjustable multi-plane unilateral external fixation can install nail arbitrary for temporary reduction and fixation within 1/3 perimeter of the injured limb. When secondary fixation, original components can fix firmly without re-set screw.
