Strength, Freedom, Simplicity
M-Vizion is Medacta’s modular femoral revision system designed to address demanding primary and complex revision cases in a versatile and flexible manner. The focus on modularity makes this an ideal option to meet the challenges of revision surgery
STRONG MODULAR JUNCTION
The M-Vizion stem features an exclusive mechanical design to increase the taper’s resistance to one of the main complications, fretting-induced fractures[1,2,3,4,5], providing for higher stability at the modular junction. The high taper mechanical resistance and conical connection strength also offer an improved resistance to fretting-induced fractures.[6]
AN ENHANCED BONE-IMPLANT INTERFACE AGAINST SUBSIDENCE
Diaphyseal stability
The design of the stem's distal portion is based on the clinically-proven Wagner concept, allowing for immediate diaphyseal stability while avoiding areas of proximal bone loss.[8,9,10,11]
Improved proximal bone fixation
The proximal body features the Mectagrip coating, a Titanium Plasma Spray application with over 10 years of clinical success.[11]
A proven robust solution for a wide patient range.
Every femur is different; therefore, every implant should be specifically shaped. The modularity of M-Vizion allows for personalization, intraoperative flexibility, and versatility when reconstructing the hip joint, making it possible to adapt to unique patient anatomies and surgical scenarios. This allows the surgeon to reconstruct the hip's rotational center, anteversion, and leg length, regardless of defect scenarios and distal fixation location.
HIGH FLEXIBILITY
A total length of 193 to 323 mm, with different possible combinations to address different femurs.
M-Vizion features straightforward instrumentation, engineered to simplify the surgical technique and maximize efficiency, confidence and reproducibility.
STREAMLINED TRIALS
reduce the surgical steps and surgical time
IN VIVO AND BACKTABLE ASSEMBLING OPTIONS
offer the opportunity to choose the preferred surgical technique
MILLIMETRIC GRADED REAMERS
allow for a step-by-step accurate and precise preparation, respecting the bone
PROXIMAL BODY RANGE
6 lenghts (10 mm increment)
4 diameters
DISTAL STEM RANGE
A total length from 193 to 323 mm, with different possible combinations to address different femurs.
M-Vizion features straightforward instrumentation, engineered to semplify the surgical technique and maximize efficiency, confidence and reproducibility.
The Trial Proximal Body has been designed with a plastic sleeve, which allows for trial the proximal body directly on the final stem. The inner plastic sleeve protects the cone of the final implant.
Allowing to chose the preferred surgical technique.
Allowing for a step-by-step accurate and precise preparation, respecting the bone.
Tapered reamers correspond to implant diameter(press-fit excluded) and are available in 1 mm steps.
The M.O.R.E. Institute offers effective and continuous education to surgeons, with the aim to improve patient outcomes and surgical proficiency. The M.O.R.E. Institute was built and has been growing, around the concept of sharing experience within the international medical community. It has become a unique and global education platform, tailored to everyone's needs.
The M-Vizion Educational Program can count on an evergrowing network of revision experts all over the world, and offers dedicated and various activities (Learning centers, Reference center visitations, user meetings, symposia) for continuous education and discussion.
