One striking feature is the increased finger-floor dis- tance that is almost invariably measured in Scheuermann patients as a result of contraction of the hamstrings. While the cause of this muscle contracture remains unclear, it may be an expression of a generally contracted posture in Scheuermann patients. Contraction of the pectoral muscles is always present in the thoracic form. Radiographic findings The typical radiographic changes are shown in ⊡ Fig. On the lateral x-ray of the thoracic or lumbar spine we observe: ▬ Schmorl nodes ▬ Apophyseal ring herniation ▬ Wedge vertebrae ⊡ Fig. Radiographic changesin the thoracic spine of a 13-year old boy with Scheuermann disease, including apophyseal ring herniation, ▬ Intervertebral disk narrowing intervertebral disk narrowing and wedge vertebrae (arrows) These findings may be located purely at the thoracic (⊡ Fig. At the thoracic level they are associated with hyperky- phosis, whereas a lumbar finding may initially only be accompanied by slight flattening of the lordosis.

The patient’s history obviously plays an important role, although it should be borne in mind that trauma details reported by adolescents can be misleading in both posi- tive and negative senses. On the other hand, pa- tients may be keen to associate back pain with a particular event that was certainly not capable of causing injury. Associated diseases ▬ Scoliosis Over 50% of patients with Scheuermann disease also suffer from scoliosis to a greater or lesser extent.

This leads to the paradoxical situation in which increased bone mass and bone softening are present at the same time, which explains the increased susceptibility to fractures.
