Spray-type External Fixation Splint Biomechanical Testing And Clinical Application

Objective:Developed by the spray-type external fixation splint for mechanical properties and preliminary clinical application on the physical properties of spray-type splint to make a preliminary evaluation and clinical efficacy.Methods:Set up 18 cases spray-type splint, traditional gypsum bandage and polyurethane bandage,which have the same thickness, length and In the universal test machine performance testing under bending, tensile performance tests, analysis of variance statistics and analysis. Finally, qualified subjects met the inclusion criteria 60 patients were randomly divided into two groups according to 1:1 and the control group, n=30. Control group was given ordinary fir plywood fixed; experimental group spray-type external fixation splint. Spray-type splints on the outside to evaluate the safety, and by observing the degree of pain and swelling, fixed effects, the healing effect, tissue compatibility and functional recovery, spray-type external fixation materials on the safety and clinical effects Evaluation.Results:Bending and tensile performance test:spray-type external fixation splint group and the group of polyester board, gypsum board group, the difference was statistically significant (P <0.05); the experimental group and control group in pain, skin allergies, Stiff joints, and so no significant difference (P>0.05), but in the fixed effects, clinical efficacy, physical pressure sores, swelling and functional rehabilitation, etc. There were significant differences (P<0.05).Conclusions:Spray-type external fixation splint bending performance than polyester boards and gypsum board; spray type of external fixation is superior tensile properties of plywood gypsum board, worse than the polyester plate. Spray-type external fixation splint is safe, no side effects, although not alleviate pain, but can increase the fracture fixed effects and clinical efficacy, reduce the incidence of pressure ulcers and limb swelling degree, is conducive to the whole limb rehabilitation post The functional exercise. Theory can be emergency, war, and excellent performance in clinical orthopedic external fixation material.
