?:definition
  • Spine surgery retractors designed to temporarily separate and hold back the edges of a posterior lumbar incision, exposing and providing access to the lumbar vertebrae and surrounding anatomical structures. These retractors are handheld, manual instruments available in a variety of shapes and styles, usually including blunt distal blades and an integral handle and are selected according to the spinal procedure to be performed. Some lumbar retractors include two blades and scissor-like ratchet handles that permit the retractor to retain its position once it is set (i.e., self-retained retractors). Dedicated retractors intended to perform minimal-access lumbar (and lower thoracic) spinal surgery (e.g., including a split tube and expanding rails to permit appropriate opening and visualization) in procedures such as a microdiscectomy are also available.
