Abstract:
[Objective]To evaluate the role of three radiographic ways in patients undergoing spinal three-dimensional correction and fusion for adolescent idiopathic scoliosis.[Method]Sixty-three cases of adolescent idiopathic scoliosis(AIS)with 79 structural curves were studied.Preoperative X-ray of standing,gravity-suspendig traction,supine bending and fulcrum bending were compared with postoperative standing X-ray one week after surgery,Cobbs angle of all X-ray were measured and statistical significance was evaluated.[Result]In structural thoracic group and lumbar group the mean Cobbs angle were 40?and 21?in gravity-suspendig traction X-ray,41?and 23?in supine bending X-ray,35?and 19?in fulcrum bending X-ray,36?and 18?in postoperative standing X-ray respectively.In severe group and moderate group the mean Cobbs angle were 52?and 23?in gravity-suspendig traction X-ray,53?and 24?in supine bending X-ray,47?and 20?in fulcrum bending X-ray,44?and 19?in postoperative standing X-ray respectively.In rigid group and flexible group the mean Cobbs angle were 51?and 22?in gravity-suspendig traction X-ray,52?and 22?in supine bending X-ray,48?and 18?in fulcrum bending X-ray,45?and 17?in postoperative standing X-ray respectively.In anterior approach group and posterior approach group the mean Cobbs angle were 47?and 15?in gravity-suspendig traction X-ray,49?and 16?in supine bending X-ray,43?and 11?in fulcrum bending X-ray,42?and 10?in postoperative standing X-ray respectively.All above Cobbs angle were mean numerical value,the mean follow-up period was 1.5 years(range:1~3 years).[Conclusion]The fulcrum bending X-ray are more predicting of correctability of AIS patients than the gravity-suspendig traction and supine bending X-ray.It can provide reference for chosing anterior or posterior approach and chosing fusion levels.
