Abstract

STUDY DESIGN: Cross-sectional analytical study. PURPOSE: To evaluate the spinal radiological features in patients with Scheuermann's disease and the association between the thoracic kyphosis angle and clinical presentation. OVERVIEW OF THE LITERATURE: Scheuermann's disease is the most common cause of hyperkyphosis of the thoracic and thoracolumbar spine in adolescents; however, literature is limited in this area.
METHODS
Data regarding 150 successive X-ray images of 95 males and 55 females diagnosed with Scheuermann's disease were retrieved from the digital archives of the Maccabi Healthcare Services in Tel Aviv. Data included thoracic kyphosis angle (T3-T12), cervical lordosis (C2-C7), lumbar lordosis (L1-S1), sacral slope (SS), number and location of the anterior wedged vertebrae (AWV, minimum 5°), and C7 plumb line. Other data included age, sex, height, family history, Risser sign, self-perceived body image (rated by the Numeric Rating Scale [NRS]), and back pain during the previous week (rated by the Numeric Pain Rating Scale [NPRS]).
RESULTS
Significant positive associations were observed between the Cobb angle of thoracic kyphosis and age (r =0.186, p =0.023), cervical lordosis (r =0.263, p < 0.001), lumbar lordosis (r =0.576, p < 0.001), SS (r =0.236, p < 0.004), T10-T12 Cobb angle (r =0.319, p < 0.001), and number of AWV (r =0.519, p < 0.001). The highest frequency of vertebral wedging was noted in T7 (68%), followed by T8 (65%) and T9 (44%). The NPRS showed a significant association only with SS (r =0.219, p =0.014). Significant positive associations were observed between the NRS for self-perceived body image, the thoracic kyphosis (r =0.494, p < 0.001), and the number of AWV (r =0.361, p < 0.001).
CONCLUSIONS
Thoracic kyphosis was significantly associated with cervical and lumbar lordosis, SS, T10-T12 Cobb angle, and AWV number. Pain was not substantial; however, self-perceived body image, the most common complaint of patients with Scheuermann's disease, was high and significantly associated with thoracic kyphosis and the number of AWV.
