Under correction of sagittal deformities based on age-adjusted alignment thresholds leads to worse health-related quality of life whereas over correction provides no additional benefit
Spine Mar 09, 2018
Scheer JK, et al. - Researchers herein compared 2-year clinical outcomes of patients who underwent surgical reconstructions based on their achievement to age-adjusted alignment ideals. Only 24.3% to 33.1% of the patients reached age-adjusted alignment thresholds at 2 years following adult spinal deformity surgical treatment. Worse clinical outcomes were demonstrated by those under corrected in sagittal vertical axis. Findings did not suggest any significant improvements between matched and overcorrected patients, with overcorrection being an established risk for proximal junctional kyphosis. The need for patient-specific operative planning was emphasized in the findings.
