Failure Prediction of Adult Spinal Deformity Surgery Comparing GAP-score With Schwab-score

The predictive value of two different score-systems with regard to failure rate following long extent spinal fusion is subject of evaluation.

Intervention / Treatment

Detailed Description

The multilevel spinal fusion is associated with high rate of failure. This results from insufficient adaptation of the fused spine to the proper individual spinal alignment. In the recent years, comprehensive understanding of spinal alignment and definition of several parameters contributed to develop score systems to evaluate the alignment of the multilevel spinal fusion and to predict failure. In the following study the results of multilevel spinal fusion were evaluated retrospectively according to two scoring systems: GAP-score und Schwab-score. The predictive value of each score system is analyzed by the correlation of the failure rate with its corresponding score value.
