Abstract

Described herein are devices and systems for accessing a spine and particularly the epidural region of the spine and methods of using these systems and devices to access the spine or regions of the spine. In particular, cannulas that may be anchored to the ligamentum flavum or the periosteum are described. Ligamentum flavum access tools are also described. These tools may be used with (or without) an anchoring cannula to penetrate the ligamentum flavum and provide access to the epidural space without risk of injury to other structures within the epidural space. The devices, methods and systems described herein are particularly useful in minimally invasive surgical (MIS) uses. The devices, methods and systems described herein may be used for performing spinal decompressions and other spinal procedures.
