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
The M.U.S.T. MIS is a comprehensive system that allows the surgeon to perform a specific surgical technique.
M.U.S.T. MINI OPEN
Specifically designed retractor for decompression, fusion and fixation with a comprehensive system of dedicated MIS instruments for optimal TLIF and PLIF cage placement
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.
Slim Percutaneous tubes provides atraumatic access.
A Small incision and gentle interface with soft tissues along with atraumatic technique may offer valuable benefits to the patient:
Dedicated connector for screws to blades gives the polyaxial screw monoaxial function, allowing for direct and effective distraction of the vertebral bodies.
Effective disc Compression & Distraction with simultaneous tissue retraction
Lever applied at the implant level for actual force transmission.
