  Author(s): Michael S. Virk and Eric ElowitzMichael S. Virk and Eric Elowitz
  
  Surgical approaches to the neural foramen and the lateral extraforaminal space in the lumbar spine are required to treat far lateral disc herniations and shwannomas. The MetRx tubular retractor system facilitates a minimally invasive technique that directly targets the region delineated by Kambin’s triangle. This study presents technical modifications, described in a step-wise fashion, to previously published approaches. We reviewed the charts of 47 patients that underwent surgery for pathology located in Kambin’s Triangle using the modified technique described here. Important technical adjustments include docking on the pars interarticularis, minimal shaving of the lateral pars and inferior articulating process, and palpation of the pedicle as a reference point for opening the ligamentumflavum and locating the exiting nerve. Potential pitfalls and strategies to .. Read More»
