The Clinical Research About The Vertebral Height Loss Rate ByUsing Different Type Of External Fixator In Stable Flexion Thoracolumbar Compression Fracture

objective:Through the observation of the treatment of stable flexion compressibility fractures of thoracic and lumbar vertebrae by Using Traction type external fixation and non Traction type external fixation.Basing on patients' pain grades and The Vertebral height loss rate,evaluate the clinical efficacy of two different external fixation.Drawing a conclusion that the therapeutic difference and application value between two different type of external fixation in treating thoracolumbar flexion compression fractures.Methods:50 patients with stable flexion thoracolumbar compression fracture were seleted from Jan to Nov 2016 by the department of traumatology,Shenzhen TCM hospital,a teaching hospital of Guangzhou University of Chinese Medicine.Patients were screened based on Western and Chinese Medicine clinical diagnostic criteria and were randomly divided into 2 groups.Group A(25 patients)accept Traction type external fixation therapy.group B(25 patients)accept non Traction type external fixation therapy.Mesure the Vertebral height and pain grades before using the Reposition Support Mattress to reset the stable flexion thoracolumbar compression fracture.Then Group A put on Traction type external fixation and group B put on non Traction type external fixation.After that,take functional exercise actively.The Vertebral height loss rate and the pain grades were involved and compared in the second,the forth and the sixth weeks after the treatment.Results:Before treatment,two groups of date were compared.Group A' s VAS score was 8.30 ± 1.19,group B' s VAS score was 8.40±1.07.the results showed p>0.05,has not statistically significant,and is comparable.Then using reposition Support Mattress to reset the stable flexion thoracolumbar compression fracture.Mesure the VAS score after resetting,after the second,the forth and the sixth weeks.Group A' s VAS score was 7.45± 1.02?4.98±0.74?2.80±0.68?1.55±0.74 respectively.Group B' s VAS score was 7.60±1.24?6.10±0.94?4.10±0.78?2.10±0.84 respectively.the various scores in 2 groups were significantly improved than before treatment(P<0.05).But group A is better than the group B,and the difference is statistically significant(P<0.05).Before treatment,The Vertebral height loss rate in group A was 29.54±2.74,after treatment was18.94±1.40,after the second week was 16.96±1.51,after the forth was 14.56±1.08,and after the sixth weeks was 13.53±1.62.Group B' s Vertebral height loss rate were 29.75±30.4,19.05±1.28?18.33± 1.55,15.91 ±1.21,15.21 ±1.44 respectively.the results showed p>0.05 between two groups before and after reseting.But in the second,the forth and the sixth weeks,The Vertebral height loss rate in group A is better than group B,and the difference is statistically significant(P<0.05).Conclusions:Both Groups has therapeutic effect in treating the stable flexion thoracolumbar compression fracture,but group A is better.it provides a more Economical ways,less Less trauma and early next bed activities avoid long-term laid-in-bed complications treatment method,have clinical popularize value.
