“…Bari et al reports no significant correlation between postoperative GAP scores and mechanical failure in their cohort of 149 patients with minimum 2-year follow-up, which questions the validity of the GAP score even with the presence of all 4 radiographic parameters. 16 Similarly, Baum et al 17 recently reported that the predicted rate of mechanical complications from the GAP score overestimated the observed rate in patients with disproportioned alignment. The current literature has mixed results on the validity of the GAP score and a further simplification of this score to use as an intraoperative tool may not be feasible.…”

“…Jacobs et al 6 performed a two-center, retrospective cohort study of 39 patients and concluded that both the GAP score and the Schwab-SRS classification were capable of predicting radiographic evidence of mechanical failure, yet the GAP score performed better with higher correlation. 3 Another single-center study performed by Bari and colleagues 7 attempted to validate the GAP score with their retrospective cohort of 149 consecutive patients who underwent deformity correction. With an overall mechanical complication rate of 51% and reoperation rate of 35%, the authors reported an AUC of 0.50 and no linear association between GAP score and occurrence of mechanical failure (p = 0.28) or revision surgery (p = 0.58).…”

“…Whereas some groups have shown good correlation between the GAP score and predicting clinical and radiographic outcomes, 5,6 others have reported weak predictive value. 7 The current objective was to examine the ability of the GAP score to predict mechanical complications after ASD surgery at a high-volume single center for spinal deformity surgery. We hypothesized that the GAP score would accurately predict the risk of mechanical complications after ASD surgery at our center.…”

“…Kwan et al 4 have recently reported that a higher GAP score does not predict mechanical complications after ASD surgery using 272 patients from the Scoli-RISK-1 prospective trial data. As mentioned above, Bari et al 2 also could not find an association with the GAP score and mechanical complications. Given that large studies could not find a direct correlation with the GAP score and mechanical complications, the study performed by the current authors sheds new light and insight onto the GAP score.…”
