Abstract: Provided are methods and systems for enlarging a spinal canal of a vertebra. Using the methods and systems disclosed the spinal canal of the vertebra is enlarged by cutting the posterior arch portion of the vertebra to create one or two implant receiving spaces in the posterior arch portion. The cutting of the posterior arch portion is completed through a minimally invasive approach. Once cut, the detached portion of the posterior arch portion is repositioned and an implant is positioned in the implant receiving space of the posterior arch portion to thereby enlarge the spinal canal such that the spinal cord is no longer compressed. The insertion of the implant is also completed through a minimally invasive approach.
