Abstract

  Lumbar disc herniation (LDH) is commonly encountered in daily medical practice, and the status of its treatment in general has been previously discussed. However, assessing the status of consultation and treatment of LDH at the Spinal Disorders Center is useful for establishing treatment principles.

  We retrospectively assessed 707 patients with LDH treated in our facility during the last 5 years. We reviewed their age, sex, Japanese Orthopaedic Association (JOA) scores, visual analog scale (VAS) scores, hernia level (L1/2, L2/3, L3/4, L4/5, L5/S1), hernia protrusion direction (medially, laterally, foraminally, extraforaminally), occurrence of spontaneous hernia reduction, surgical rate, surgical method (discectomy, laminectomy, discectomy with fusion), recurrence, complications, and need for reoperation, among other items.

  We found that the average age at onset was older than that in previous reports because of the increase in our aging population in recent years. Also, the surgical rate (38%) was higher than in other reports because of the specialty characteristics of the Spinal Disorders Center. In addition, we were able to determine the characteristics of LDH at each level and each type by classifying LDH according to the level and the hernia protrusion direction (four types) in detail. The surgical rate for upper LDH tended to be higher for the medial protrusion type. The surgical rate for lower LDH tended to be higher for the extraforaminal type. Moreover, upper LDH (foraminal type) more often underwent lumbar interbody fusion with discectomy than any other LDH type at any of the other levels.

  This study has provided data in one of neurosurgical facilities in Japan. We believe that it could help promote more surgical activity by Japanese neurosurgeons in this field.
