title: [Comparative analysis of pedicle screw versus hybrid instrumentation in posterior spinal correction of adolescent idiopathic scoliosis].
abstract: OBJECTIVE
  To compare the effect of posterior correction and fusion between segmental pedicle screw instrumentation with hybrid constructs in adolescent idiopathic scoliosis (AIS).
  
  
  METHODS
  Study the clinical data of 40 AIS patients retrospectively. They were underwent posterior fusion and be distributed into two group, group A was hybrid instrumentation (20 cases) and group B was pedicle screw instrumentation (20 cases). Compared therapy effect, operative time, intraoperative blood loss.
  
  
  RESULTS
  The average major curve correction was 82.4% in the screw group and 71.8% in the hybrid group (P = 0.004). After one to three years follow-up, major curve correction was 77.0% and 62.5% respectively (P = 0.001). Average apical vertebral derotation showed 63% correction in the screw group and 32% in the hybrid group (P = 0.001). There was no statistical significance between two group in thoracic sagittal correction, the lowest instrumented vertebra below the lower end vertebra, trunk shift, operative time, and average estimated blood loss. There were no neurologic complications related to hybrid or pedicle screw instrumentation.
  
  
  CONCLUSIONS
  Pedicle screw instrumentation was significantly better than hybrid constructs.
