Scoliosis curve: before and after surgical correction

The main purpose of this study was to report the surgical experiences and to evaluate the effectiveness of Two-stage operation (including 1-anterior release and fusion with hylofemoral traction and 2-posterior correction and fusion) in scoliosis. The prospective study was performed on 45 scoliotic patients presenting to Tabriz Shohada Orthopedics Teaching Referral Hospital between January 2002 and July 2007. Two-stage operation (anterior release and fusion with hylofemoral traction followed by posterior correction and fusion) was performed for cases in which the scoliosis angle was > 70 degrees and the correction level on bending films was less than 50%. Forty five patients, 32 (71.1%) female and 13 (28.9%) male, with mean age of 15.13 +/- 0.34 years (range of 10 to 18 years), were studied. According to the consecutive sampling, the relation of scoliosis with patients sex was significant (p < 0.005). The mean scoliosis angle was 73.31 +/- 4.21 before operation and 36.11 +/- 2.56 after operation (p < 0.005). The mean preoperative kyphosis angle was 29.95 +/- 3.9 and the mean postoperative kyphosis angle was 24.6 +/- 2.2 (p < 0.005). Scoliosis was significantly more severe in males than females.
