To find accompanying anomalies of typical and atypical Scheuermann’s disease (SD) is reported in the present study.
Study included 20 patients (16 men and 4 women) who had radiological imaging radiography, magnetic resonance imaging (MRI) and computed tomography, if available, due to back pain, curved back and low back pain in November 2011-February 2016 period. Patients were categorized into typical and atypical patterns based on the region involved. Thoracic kyphosis values were measured using real Cobb angle. Accompanying disc degeneration, herniations and spinal cord pathologies were studied using MRI.
Age of the patients ranged from 11.0 to 23.0 (mean 17.2 ± 3.0). Typical pattern of SD were detected in 15 patients while atypical pattern were detected in 5 patients. Cobb angle range was 40.2-67.2 (mean 55.5 ± 8.7) in typical Scheuermann’s patients and 24.7-49.9 (mean 36.7 ± 10.8) in atypical ones. Intervertebral level was affected and had the measures of 3-8 (mean 5.3 ± 1.6) and 7-9 (mean 8.2 ± 0.8) in typical and atypical Scheuermann’s patients, respectively. Level of degenerative disc disease in MRI was 1-7 discs (mean 4.1 ± 1.7) in typical patients and 5-10 discs (mean 7.6 ± 1.9) in atypical patients.
SD can be seen in typical and atypical patterns, typical being more frequent. Because degenerative disc diseases, herniations and cord pathologies such as syringomyelia can accompany SD (albeit more common in atypical pattern), it is necessary to evaluate these patients with plain radiography and MRI together.
Core tip: Scheuermann’s disease (SD) is the most common cause of degenerative structural thoracic or thoracolumbar hyperkyphosis associated with back pain in adolescents and could be observed in typical and atypical patterns. It manifests itself with successive endplate irregularities and anterior vertebral wedging in radiography, and additionally as disc degenerations, herniations and syringomyelia in spinal cord in magnetic resonance imaging (MRI). Impairment in intervertebral distance and disc degeneration are more evident in SD with atypical pattern. When multiple endplate irregularities and anterior vertebral wedging are observed in MRI of patients thought to have thoracolumbar disc pathology, SD should be considered.
