Short-Term Preoperative Traction Method for Rigid and Severe Scoliosis

Completed

• Conditions: Scoliosis Idiopathic
• Interventions: Procedure: Preoperative traction

• Registration Number: NCT04671147
• Lead Sponsor: Indonesian Orthopaedic Association

Brief Summary

The investigators collected retrospective data of severe (\>80o) and rigid scoliosis patients who underwent preoperative traction before correction surgery from 2016 to 2018. The first group consisted of patients who underwent Cotrel traction exercises and second group underwent continuous-progressively increasing Skull Tongs Femoral Traction (STFT) traction. Posterior fusion was performed in all patients. Intraoperative parameters (blood loss, operation time and level instrumented) and radiologic change (initial, post-traction and postoperative Cobb Angle) was evaluated and analyzed
