Meta-analysis of lumbar disc herniation in Chinese adolescents

Abstract

OBJECTIVE:

To provide evidence-based medicine rationales for the diagnosis and treatment of lumbar disc herniation (LDH) in Chinese adolescents.

METHODS:

The related medical literature of pediatric LDH between January 1990 and December 2012 was collected by retrospective searches of WANGFANG and CNKI databases. The data concerning mechanism, clinical manifestations, diagnosis and treatment were recorded and analyzed.

RESULTS:

A total of 1208 cases of LDH in adolescents were retrieved from 45 articles. Most of them were males (74.2%). And the primary cause was trauma (65.9%). Their clinical presentations were characterized by mild symptoms and serious physical signs. And 87.0% of them had a positive straight-leg raising test. Single-level intervertebral disk protrusion accounted for 92%. And the levels were at L4-L5 (54.7%) and L5-S1 (37.6%). There was a higher incidence of lumbar scoliosis deformity (38.2%), lumbar spine physiological curvature change (41.4%) and loss of vertebral height (33.6%) in adolescents than adults. There were many different treatments for pediatric LDH. Each method had its own advantages and disadvantages. The success rates of micro endoscopic discectomy (MED) and open discectomy were more than 90%.

CONCLUSION:

Trauma is a common cause of pediatric LDH. Males are more frequently affected. The single-level protrusion of L4/5 or L5/S1 has a much higher incidence. Positive straight-leg raising test and imaging findings of lumbar scoliosis deformity, lumbar spine physiological curvature change and a loss of vertebral height may aid the diagnosis. Normally conservative treatment is offered. And chemonucleolysis, MED and open discectomy are alternative options.
