Short-Term Preoperative Traction Method for Rigid and Severe Scoliosis
Short-Term Preoperative Traction Method for Rigid and Severe Scoliosis
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
Inclusion Criteria:

 -  adolescence/adult idiopathic scoliosis;

 -  severe and rigid scoliosis (defined as Cobb angle more than 80° and flexibility index
 less than 25%);

 -  either skull tongs-femoral traction or Cotrel longitudinal traction used in the
 preoperative time period

 Exclusion Criteria:

 -  other types of scoliosis (neuromuscular scoliosis, congenital scoliosis, etc.)

 -  intradural abnormalities (diastomatomyelia, tethered cord, etc)

 -  history of previous spine surgery
