Adolescent Disc Disease: Risk Factors and Treatment Success-Related Factors

OBJECTIVE: A paucity of literature is available discussing the associated risk factors, treatment options (including the use of minimally invasive surgery), and outcomes related to lumbar disc herniation (LDH) in children. We have discussed the risk factors for disc disease among pediatric patients and evaluated the efficacy of the minimally invasive approach. METHODS: A retrospective review of pediatric patients with lumbar disc disease who had undergone micro-discectomy at our institution from 2005 to 2016 was conducted. The preoperative presentation, hospital course, postoperative course, and follow-up data (>= 3 years) were reviewed. We evaluated the risk factors for LDH and the surgical outcomes for both groups. RESULTS: A total of 52 pediatric patients had undergone 61 lumbar disc surgeries for LDH in our department from 2005 to 2016. Their average age at surgery was 16.65 years. Of the 61 procedures, 48 (78.7%) had been performed via the minimally invasive spine microdiscectomy approach and 13 (21.3%) via the open microdiscectomy approach. The average body mass index for all cases was 29.3 kg/m(2). The average interval to diagnosis was 7.9 months. Of the 61 cases, 21 (34.4%) had been required for patients who were competitive athletes. In addition, 15 had been for LDH related to trauma (24.6%). In 46 of the 61 cases, complete resolution of the symptoms had occurred at the 1-year follow-up visit (79.2% of minimally invasive spine microdiscectomy vs 61.5% of open microdiscectomy). CONCLUSION: Risk factors similar to those for adult LDH, such as an elevated body mass index, can be seen in the pediatric population. However, some unique risk factors such as post-traumatic LDH were found in the pediatric age group. Minimally invasive techniques are demonstrably safe and useful in this patient population.

Automated summary

The study reviewed 52 pediatric patients who underwent lumbar disc surgeries from 2005 to 2016, finding that minimally invasive techniques are safe and effective in this population, with a high rate of complete symptom resolution postoperatively.
