During a discectomy, safely retracting the nerve root is paramount to avoid neurological complications. Traditional methods may involve retractors that could exert excessive pressure on the nerve root, leading to potential damage. The biportal nerve root retractor is designed to address these concerns.
Unilateral portal endoscopic discectomy involves the use of two small portals: one for the endoscope and another for surgical instruments. This technique allows for direct visualization of the surgical field and precise manipulation of instruments while minimizing tissue disruption.
