A fifteen year old boy with progressive Scheuermann kyphosis and serious back pain. Late referral but first treated with physical therapy between first and second X-ray. Wedging and Schmorl’s nodi mainly in the thoracolumbar area (Cobb Th10-L2: 20°). Picture taken after the first night wearing a TLI brace: Clockwise: Left: standing, some scapular asymmetry is present. Middle: lateral view while active standing upright. Right: the contracted neuromuscular system while bending forward. Note the impossibility to keep the legs vertical, get the lumbar spine horizontal and the visible tight hamstrings. Flexion occurs in the upper spine, not around the hips. Under right : the skin of his back after the first night of wearing a TLI brace. The main pressure is on the paraspinal musculature with the apex at the thoracolumbar area at the same level as the elbow pits. There is no pressure mark on the processi spinosi or the lower ribs. In the middle: sitting with straight legs and left sitting on the edge of the couch. The thoracolumbar kyphosis redresses itself somewhat. TLI will maintain this continuously with progressive reduction.
