Abstract
A retractor assembly for defining a working channel to a surgical site for conducting minimally invasive spinal surgery includes a plurality of relatively articulable components. Temporary interconnections are formed between adjacent sidewalls of the components to hold the components in a de sired configuration, such as in a closed triangular form. The components are articulable relative to each other for adjusting the working channel or for performing surgical functions.
