Purpose: Standard thoracotomy for anterior instrumentation and fusion of the thoracic
spine in idiopathic scoliosis may have detrimental effects on pulmonary function.
In this study we describe a less invasive anterior surgical technique and show the
pre- and postoperative pulmonary function with a minimum follow-up of 2 years.
Methods
Twenty patients with Lenke type 1 adolescent thoracic idiopathic scoliosis were treated
with anterior spinal fusion and instrumentation. The mean preoperative Cobb angle
of the thoracic curve was 53[degree sign] +/- 5.8. Pulmonary function tests (PFT)
and radiographic evaluation was performed.
Results
The mean postoperative correction in Cobb angle of the thoracic curve was 27[degree
sign] +/- 8.2 (49%).
The mean preoperative FEV1 was 2.81 +/- 0.43 L, which increased to 3.14 +/- 0.50 L
at 2 years postoperatively (P = 0.000). The mean FEV1% did not change (89.60 +/- 7.49%
preoperatively, versus 90.53 +/- 5.95% at 2 years follow-up, P = 0.467). The TLC increased
from 4.62 +/- 0.62 L preoperatively to 5.17 +/- 0.63 L at 2 years follow-up (P = 0.000).
The FEV1% at two years of follow-up improved to 104% of the FEV1% predicted value.
The FEV1 improved to 97% of the FEV1 predicted value.
Conclusion
Anterior spinal fusion for idiopathic scoliosis by means of a minimal open thoracotomy
proved to be a safe surgical technique that resulted in an improvement of pulmonary
function. Our results are similar to those of thoracoscopic procedures reported in
literature.
