To Compare The Clinical Effects Of Curing Thoracic And Lumbar Fracture(T11-L2) By Minimally Invasive Therapy Under Orthophoria And Percutaneous Minimally Invasive Treatment

Purpose: To compare the clinical effects of curing thoracic and lumbar fracture(T11-L2) by minimally invasive therapy under orthophoria and percutaneous minimally invasive treatment.Method: Regarding 50 cases of thoracic and lumbar fracture without nervous system impairment from spine surgery of Qinghai University Affiliated Hospital from November 2014 to June 2015 as research objects. Experimental group and control group are randomly divided. Research object selection standards: 1 Injury mechanism:Injury history like car accident, falling accident but not pathological fracturea caused by other reasons like rarefaction of bone or cancer.2 Age limit: 18~55. 3 Clinical symptoms: without limb perception activity obstacleor perineum sensory disturbance. 4 Auxiliary examination : thoracolumbar X-Ray, thoracolumbar CT three-dimensional reconstruction and MRI visible T11-L2 single segmental vertebral fracture. The diagnosis is clear. Experimental group adopts minimally invasive pedicle screw fixation operation under orthophoria, and control group adopts percutaneous minimally invasive pedicle screw fixation operation. Separately record and clinically compare slash lengths, operation times, amount of bleeding during operation, perspective times during operation, lengths of stay, wound healing conditions, consumable costs, front height percentage of wounded vertebra before and three months’ after operation, 48 h VAS score data of two groups.Result: Patients of experimental group and control group accept post-operation follow-up through periodic shooting of thoracolumbar X Ray three months’ after the operation. Orthophoria minimally invasive group(experimental group): slash lengths 10.42±0.63 cm, operation times 87.20±4.65 min, perspective times during operation 2.80±0.41 times. Percutaneous minimally invasive group(control group): slash lengths 12.18±0.32 cm, operation times 108.08±6.77 min, perspective times during operation 13.76±1.92 times. All differences own statistical significance(p<0.05). The differences of front height percentage of wounded vertebra before and three months’ after operation and 48 h VAS score data between experimental group and control group do not have statistical significance(p>0.05). The fixed consumable cost of experimental group is RMB 28243.6, and that of control group is RMB 30143.6. Experimental group costs less than control group. Slash healing conditions of two groups are all I/A, which means complete healed, and the healing effects are the same.Conclusion: Orthophoria minimally invasive treatment and percutaneous minimally invasivetreatment are different minimally invasive operations, while they have the same clinical effect in curing thoracic and lumbar fracture without nerve injury(T11-L2). Orthophoria minimally invasive technology is easier to be learned, more economical. It can avoid excessive iatrogenic radiation, and has unparalleled advantages than percutaneous minimally invasive technology.
