The Ravine Lateral Access and Aleutian Lateral Interbody Systems received CE mark, the approval was announced on 15 March 2011 by K2M, producer of the spine devices.
Ravine provides a dual flat blade platform for a true muscle-splitting transpsoas approach. The system offers rigid fixation to the spine and an option for both a third and fourth blade. It represents an innovative design departure from the tubular retractors, while providing tremendous adaptability to both patient anatomy and surgeon technique.
Aleutian Lateral is comprised of anatomically designed interbody implants made of PEEK material that are used in conjunction with the Ravine Retractor. The implants feature radiolucent properties, which have the potential to increase visualisation of bone graft while aiding in accurate fusion assessment. The bulleted nose allows for ease of insertion and the circumferential rings provide 360 degrees of grip to the endplates.
“Ravine is simple and easy to use. The retractor fixes to the vertebrae, as opposed to the operating table, and has a small footprint to potentially reduce the risk of surgical damage. It uses the anatomy of the muscle and the plexus to its advantage with the split and twist technique,” said Colin Natali, orthopaedic surgeon, Royal London Hospital, UK. “The system evolved from the collaboration of surgeons and engineers working in unison to provide leading, rather than following, technology.”
“CE mark clearance for Ravine and Aleutian Lateral expands the K2M minimally invasive product offering and fuels our rapid international growth,” stated Eric Major, K2M’s president and CEO. “These high profile next generation products reaffirm our commitment to becoming a leader in the global spine market.”
