Abstract

Minimally invasive surgical techniques including techniques and implants for provision of therapy to a spine from a lateral approach. Implants that may be used with other approaches to the spine are disclosed. Minimally invasive surgical techniques using one or more extended retractors to create an extended access route such as the non-limiting example of lateral access to the spine. Minimally invasive surgical techniques using internal retractors that may be reversibly expanded with a removable retractor inserter to create an extended access route. A linkage jack to expand a set of two or more extended retractors to create an extended access route.
