不同剂量微波治疗对骨折术后钛合金植入物毗邻组织的影响
Effects of different doses of microwave therapy on adjacent tissue of titanium alloy implants after fracture surgery
摘要
Abstract
BACKGROUND: Microwave treatment is a common physical therapy method that can increase the temperature and blood circulation of deep tissues, and is used for improving fracture repair. However, microwave treatment cannot be used if there is surgically implanted metal plate or screw. OBJECTIVE: To observe the dame of microwave treatment to the tissues surrounding the titanium alloy implants. METHODS: Forty-four New Zealand white rabbits were randomized into experimental and control groups. The model of the fracture at the middle of the femur was established in all rabbits, and the rabbits in the experimental group were implanted with titanium alloy internal fixation systems. A 30-day microwave treatment (2 450 MHz, 20 W or 40 W, 20 minutes daily) was applied to the fracture site in all rabbits at 3 days after operation. RESULTS AND CONCLUSION: After 20 W of wave microwave treatment, the temperature of tissues around the implants showed no significant increase or severe heat injury. While, 40 W of wave microwave treatment significantly increased the temperature of tissues around the implants and the tissue was damaged severely. Our results indicate that, the low-dosage microwave treatment may be a promising method in the rehabilitation therapy of fractures with titanium alloy internal fixation.关键词
