Classification In humans, these conditions may be classified into three groups: # Spinal: Scheuermann's disease(of the interspinal joints) which is a curve in the thoracic spine. # Articular: Legg-Calvé-Perthes disease (or, avascular necrosis of the femoral head in the hip), Köhler's disease (of the tarsal navicular bone of the foot), Freiberg's infraction (of the second or third metatarsal of the foot and less frequently the first or fourth; sometimes called Freiberg's Infraction or Freiberg's disease), Blount's disease (tibia vara), Kienböck's disease (lunate), Panner's disease (of the capitulum of the elbow). Other entities affecting mostly adults, but sometimes loosely lumped into these conditions include Preiser's disease (scaphoid) and Muller-Weiss syndrome (tarsal navicular). # Non-articular: This group includes Sever's disease (of the calcaneus, or heel), and other conditions not completely characteristic of the<unk> , such as Osgood-Schlatter's disease (of the tibial tubercle) and Sinding-Larsen-Johansson syndrome (proximal patellar tendon).
