Abstract

OBJECT:

Lumbar disc herniation is rare in the pediatric age group, but may still cause a significant amount of pain and disability. Whereas minimally invasive surgery (MIS) for lumbar disc herniation is routinely performed in adults, it has not yet been described in the pediatric population. The purpose of this study was to describe the surgical results of pediatric MIS-treated lumbar disc disease.

METHODS:

The authors retrospectively reviewed a series of 6 consecutive cases of lumbar microdiscectomy performed using MIS techniques between April 2008 and July 2010. Presenting symptoms, physical examination findings, and preoperative MR imaging results were obtained from medical records. Perioperative results, including blood loss, length of hospital stay, and complications were assessed. Findings at latest follow-up evaluation were also recorded.

RESULTS:

This report represents the first surgical series regarding pediatric lumbar microdiscectomies performed using MIS. The mean patient age was 16 years (range 14-17 years); there were 4 girls and 2 boys. Preoperative signs and symptoms of radiculopathic pain were notable in 100% of patients, and myotomal weakness was noted in 33% of patients. The first line of treatment in all patients was a period of conservative management lasting an average of 11.5 months (range 6-12 months). The mean intraoperative blood loss was 10.8 ml, and the mean postoperative length of stay was 1.3 days. There were no complications in this small series.

CONCLUSIONS:

The treatment of pediatric lumbar disc herniation by using MIS techniques can be safe and efficacious. However, further study with a larger number of patients and longer follow-up is needed to compare outcomes between MIS and open microdiscectomies.
