Concerning the development of spine we have to realize the importance of back pain in children. Sex related factors may play a role in spinal deformities and injuries. Lomber disc herniation (LDH) at childhood is observed in dumbbell sport or after lifting heavy loads where forces in direction of flexion are experienced. LDH at childhood may not present with symptoms. In treatment bed rest, bracing, exercise with physical agents and in unresponsive cases use of epidural corticosteroid injections are preferred. Cases with neurologic deficit and cauda equina syndromes should be treated surgically.
