背景:对骨折区域采用金属植入物进行内固定后,进行物理治疗且辅以康复训练是否可以促进骨折愈合?实验对此进行探索.目的:验证骨折金属植入物内固定后物理治疗的可行性,观察其对骨折愈合及周围组织的影响.方法:选取24只成年大白兔,随机分为3组.制作右侧股骨中段横断性骨折模型,并用钢板内固定.内固定后空白对照组不采取任何治疗;中频治疗组自内固定后第4天起,连续30 d 采用电脑中频治疗仪 ECM99-IIB 治疗;高频治疗组自内固定后第4天起,连续30 d 采用微波治疗仪 PM-800S 进行治疗.结果与结论:大体观察所见空白对照组纤维组织最多,中频治疗组次之,高频治疗组最少.神经传导速度3组间比较差异无显著性意义(P >0.05).组织学观察空白对照组未见明显骨基质,中频治疗组可见形成中骨小梁,高频治疗组可见较为成熟的骨小梁.空白对照组肌肉组织大量纤维化,中频治疗组肌肉组织可见部分纤维化,高频治疗组纤维化程度最低.血清生化指标结果显示 Ca2+和碱性磷酸酶指标高频治疗组、中频治疗组显著高于空白对照组(P <0.05).结果表明,高频电疗及中频电疗法可应用于股骨骨折内固定后,且对于骨折的修复具有促进作用,高频治疗的效果优于中频治疗.

BACKGROUND: After fracture fixation with metal implants, is it able to take physical therapy in promoting the fracture? This exploratory experiment can be the preparation for later discussion. OBJECTIVE: To investigate the feasibility of physical therapy after fracture fixation with metal implants and to observe the effect of physical therapy on the fracture recovery and surrounding tissues. METHODS: Twenty-four adult white rabbits were selected and randomly divided into three groups. The models of the transaction fracture on the middle of left femur were established and fixed with plate. After fixation, the models in the control group received no treatment; the models in the intermediate-frequency group received the intermediate-frequency electro-therapy with intermediate-frequency therapeutic equioment ECM99-IIB at 4 days after fixation and lasted for 30 days; the models in the high-frequency group received the microwave therapy with microwave apparatus PM-800S at 4 days after fixation and lasted for 30 days. RESULTS AND CONCLUSION: General observation showed that the control group had the most fibrous tissue, fol owed by the intermediate-frequency group, and high-frequency group had the least fibrous tissue. There was no significant difference of nerve conduction velocity among three groups (P > 0.05). Histological observation showed that there was no visible bone matrix in the control group, trabecular bone formation could be seen in the intermediate-frequency group, maturate trabecular bone could be seen in the high-frequency group. Fibrosis of muscle tissue could be seen in the control group, partly fibrosis of muscle tissue could be seen in the intermediate-frequency group and the fibrosis in the high-frequency group was not obvious. Serum biochemical indicators showed that the serum content of Ca2+ and alkaline phosphatase in the intermediate-frequency group and high-frequency group were significantly higher than those in the control group (P < 0.05). Under the experimental conditions, intermediate-frequency electro-therapy and high-frequency electro-therapy could be used after fracture fixation, and had a positive effect on the union of fracture. The effect of the high-frequency electro-therapy was better than that of the intermediate-frequency electro-therapy.
