Abstract
Background: The aim of current study was to compare the effects of all-pedicle-screw versus hybrid fixation techniques in surgical correction of adolescent idiopathic scoliosis.Methods: This clinical-trial study conducted on 40 patients who underwent corrective scoliosis surgery using all-pedicle-screw technique. Surgical outcome was assessed using radiological criteria (major Cobb’s angle correction) and Scoliosis Research Society-30 (SRS-30) questionnaire with measurements done before and two years after surgery. Findings were compared with results of 40 similar patients’ outcomes found in another study with hybrid fixation technique.Findings: Mean correction of Cobb’s angle in all-pedicle-screw and hybrid fixation groups was 82.7 and 76.3 percent, respectively. Rate of correction was significantly higher in all-pedicle-screw group (P = 0.044). Based on SRS-30 questionnaire, all domains scores were significantly improved in all-pedicle-screw group and in comparison to hybrid fixation, this method was only significantly better in patients' personal image/appearance and satisfaction domains (P < 0.001).Conclusion: Both techniques of pedicle screw and hybrid fixation are effective in correction of scoliosis, but this correction is more desirable in all-pedicle-screw group. Patients who had undergone all-pedicle-screw technique in comparison to hybrid fixation showed higher rate of satisfaction from surgery and personal image/appearance.
