A Novel Approach to the Surgical Treatment of Lumbar Disc Herniations: Indications of Simple Discectomy and Posterior Transpedicular Dynamic Stabilization Based on Carragee Classification

<table>A large annulus defect (&gt;4 mm) was observed at the midline of posterior annulus fibrosus. Integrity of annulus is preserved (Carragee Type IV). The patient is unresponsive to the conservative treatment and PTDS was applied to the patient after L5-S1 microdiscectomy and annular repair.</table>
