Comparison of the effects of minimally invasive percutaneous pedicle screws osteosynthesis and open surgery on repairing the pain, inflammation and recovery of thoracolumbar vertebra fracture.

We compared the clinical effects of minimally invasive percutaneous pedicle screws osteosynthesis (MIPPSO) and open surgery on the repair of thoracolumbar vertebra fracture. Seventy patients, who suffered from thoracolumbar vertebra fracture and received treatment at our hospital, were selected and randomly divided into either the minimally invasive percutaneous pedicle screws osteosynthesis group (MIPPSO group) and the traditional open pedicle screws osteosynthesis group (TOPSO group) with 35 cases in each group. The perioperative parameters including length of incision, duration of operation, bleeding during operation, length of hospital stay, the changes of pre-operative and postoperative VAS pain scores, inflammatory indexes including serum C-reactive protein (CRP) and creatine kinase (CK), and imaging indexes including Cobb's angle and anterior margin height of vertebral body of both groups were compared. The length of incision, duration of operation, bleeding volume during operation and length of hospital stay in the MIPPSO group were significantly lower than those in the TOPSO group (P<0.05). Both minimally invasive surgery and traditional surgery effectively alleviated the pain (P<0.05), which was more significant in MIPPSO group (P<0.05). The postoperative inflammatory indexes, CRP and CK levels, of both groups were higher compared to the pre-operation (P<0.05), which was more significant in TOPSO group (P<0.05). The differences of imaging indexes, including Cobb's angle and anterior margin height of injured vertebra, were statistically significant between pre-operation and post-operation for each group (P<0.05); however, there were no statistically significant differences between two groups at either pre-operation or post-operation (P>0.05). The effect of minimally invasive percutaneous pedicle screws osteosynthesis is similar to the traditional open surgery, however, the MIPPSO technique has the advantages of small trauma, less bleeding, short duration of operation, rapid post-operative recovery, light pain, less economic cost, and better aesthetic effect and is therefore worthy of clinical promotion.
