We report two cases of lumbar disc herniation with dislocation of ring apophysis. They were boys and ages were 15 and 16. They complained of severe low back pain during basketball and volleyball. Lateral plain X-ray revealed small abnormal shadow in spinal canal at the level of L4/5. Myelogram showed complete block at this level. We operated on them for suspected lumbar disc hernation with dislocation of ring apophysis and results of both were good.
13 cases had been reported by other authors. 14 cases of 15 of this disease experienced trauma. We think that trauma plays a more important role in the lumbar disc herniation with dislocation of ring apophysis than other herniation in adolescent children.
