Background

There was a controversy about surgery approach of severe rigid congenital kyphoscoliosis in adolescence treatment. Aim of the study is to compare the clinical efficacy of surgical treatement by hemivertebra resection (HR) and hemivertebra resection combined with wedge osteotomy (HRWO) for severe rigid congenital kyphoscoliosis in adolescence.

Methods

Twenty-five patients with severe rigid congenital kyphoscoliosis between Jan 2006 and Dec 2011 were studied in our center. The patients were divided into hemivertebra resection group (group HR) or hemivertebra resection combined with wedge osteotomy group (group HRWO). The clinical and radiographic evaluation in terms of operation time, blood loss, correction rate, fusion time, hospital stay, complications and SRS-24 questionnaire score were compared between Group A and Group B.

Results

It is obvious that group HR achieved much better results in time of operation time, intra-operative blood loss, and hospital stay than group HRWO (P < 0.05). But meanwhile, group HRWO was significantly better than group HR in the times of coronal Cobb angle, kyphosis, the sagittal imbalance, coronal imbalance and SRS-24 questionnaire score (P < 0.05). There were no significant differences between the two groups in the age, mean flexibility, follow-up time, fusion time, and complications in the last follow-up (P > 0.05).

Conclusion

The outcomes of follow-up showed that the hemivertebra resection combined with wedge osteotomy approach obtained better clinical outcomes hemivertebra resection surgery. It might be a better surgical treatment for severe rigid congenital kyphoscoliosis in adolescence patients, but it needs longer operation time, more intra-operative blood loss, and extended hospital stay.
