The parents of sixty-three patients who were less than twenty-one years old and who had operatively confirmed herniation of a lumbar disc were interviewed regarding a history of sever back pain, sciatica, and herniated disc, to determine whether aggregation of herniation of a lumbar disc occurs in families of patients in this young age-group. The parents of sixty-three additional patients who h...

OBJECTIVES To explore the microendoscopic discectomy technique and inclusion criteria for the treatment of recurrent lumbar disc herniation and to supply feasible criteria and technical notes to avoid complications and to increase the therapeutic effect. METHODS A consecutive series of 25 patients who underwent posterior microendoscopic discectomy for recurrent lumbar disc herniation were inc...
