Purpose

To evaluate pulmonary function and clinical and functional outcomes in patients with adolescent idiopathic scoliosis (AIS) treated with posterior spinal fusion and thoracoplasty.

Materials and methods

We evaluated prospectively 18 consecutive patients with thoracic AIS treated with instrumented posterior spinal fusion with concomitant thoracoplasty with a 2 years follow-up. Pulmonary function was assessed by forced vital capacity (FVC) and forced expiratory volume in one second (FEV₁) before surgery, and one and two years after surgery. We used the SRS-22 questionnaire to assess the clinical outcomes before surgery and two years after surgery.

Results

Average absolute preoperative FVC was 2.63 L (theoretical predictive value FVC:77.15 % ) while FEV₁ was 2.29 (theoretical predictive value FEV₁:79.46 % ). At one year postsurgery, mean values of FVC and FEV₁ were, respectively, 2.77 and 2.48 (theoretical predictive value FVC: 79.8 % and FEV₁:85.2 % ). At two years postsurgery, mean value of FVC was 2.86 L and 2.64 L for FVC and FEV₁ respectively, that is, FVC: 81.8 % , and FEV₁:89.15 % . The improvement in the self-image item of the patients after surgery on the SRS-22 questionnaire is very significant.

Conclusions

The pulmonary function tests show that these scoliotic patients have a significant progressive improvement of FVC and FEV₁ at one and two years postsurgery, compared with the preoperative values.
