Abstract

Study design: Long-term cross-sectional study.

Objectives: To investigate the long-term effects of untreated Scheuermann’s kyphosis on quality of life, and its relationship to radiographic parameters of spinal deformity. Previous studies reported reduced self-image, increased pain and impaired physical status. Little is known of the long-term impact of sagittal plane deformity in untreated SK.

Methods: One hundred and thirteen consecutive untreated patients with SK were identified from a national service database prior to 2000, when surgery was not offered at this unit. 81 of these patients were available for evaluation; 66 (81%) consented to questionnaire and clinical evaluation, and 47 (58%) consented to additional radiological evaluation. Health-related quality of life (HRQoL) was compared to normative population values. Mean age was 45.1 years (31-65), and mean follow-up was 27 years (16-36). 57 patients had thoracic kyphosis and 9 had thoracolumbar deformity.

Results: SRS-22 and SF-36 scores were lower, and ODI was greater in patients with untreated SK compared to normative population values. Kyphosis progressed from mean 66° at skeletal maturity to 78° (p < 0.001) after mean follow-up of 27 years. Long-term progression of untreated SK was 0.45°/year (n = 47). Multilinear regression showed good correlation between increasing SVA and worse ODI scores (r = 0.59; p = 0.001). Increasing SVA also correlated with worse function, pain and mental health scores reported by SRS-22, and with worse physical function and bodily pain scores reported by SF-36. Increasing CL correlated with worse SF-36 physical function scores. Increasing cSVA and increasing TK correlated with worse SRS-22 self-image scores.

Conclusion: SRS-22 and SF-36 scores were lower, and ODI was greater in patients with untreated SK compared to normative data. Long-term progression of untreated SK was 0.45°/year (n = 47). Increasing SVA correlated with worse SF-36 physical function, SRS-22 function, SRS-22 pain and higher ODI scores. Total kyphosis (TK) and cSVA were independent predictors of low SRS self-image.
