Make It Smart
in One System

The MUST MIS System represents an effective and harmonic concept in terms of minimally invasive solutions. The MIS system is composed of

  • an innovative mini open retractor
  • a percutaneous system
  • TLIF and PLIF cages with dedicated MIS Instruments

The MUST MIS system guarantees enhanced visualization and direct access for simplified implant insertion.

Easy unilateral transforaminal approach thanks to: 

Gentle interface to soft tissues due to a low profile instruments design
Improved disc space preparation with Mini Open Retraction / Distraction



Effective in situ space through dedicated offset PLIF and TLIF cage inserters.
 

The Medacta MIS system relies on a dedicated MUST screw based platform assuring superior stability.

Percutaneous tower specifically designed for MUST cannulated screws.

Effective screw-to-screw based distraction concept providing enhanced stability and preventing construct migration.

 

Low Profile frame with ergonomic and radiolucent blade design to provide large visual exposure.

 

Dedicated light cables for optimal site illumination

 

Slim Percutaneous tubes provide atraumatic access.

A Small incision and gentle interface with soft tissues along with atraumatic technique may offer valuable benefits to the patient:

  • Small incisions
  • Reduced blood loss [1]
  • Reduced site infection [3]
  • Potential reduced vasculature disruption
  • Minimize soft tissue and muscle injuries [2]
  • Reduced post-op pain-killer therapy [1]
  • Minimum scar
  • Improved patient’s recovery [1]
  • Rapid hospital discharge [2]

Dedicated connector for screws to blades gives the polyaxial screw monoaxial function, allowing for direct and effective distraction of the vertebral bodies.

Medacta Spine has developed a portfolio of spine implants designed to complement one another.
The M.U.S.T. Pedicle Screw System, the MectaLIF Family of Interbody Fusion Devices and the M.U.S.T. MIS system create a harmonized, single-system approach for most spine stabilization applications.
