MySpine S2AI is the Medacta Patient-Specific Solution for S2-Alar-Iliac fixation: a minimally invasive solution at surgeon’s hand for long constructs, designed to overcome the limits of a potentially insufficient lower spine fixation.
The S2-Alar-Iliac technique represents a valid solution since the trajectory crosses 5 cortical bone structures, resulting in a strong bone fixation, leading to reduced screw loosening rate[5] compared with alternative lumbosacral instrumentations (S2-Alar and Iliac screws).
MySpine S2AI can be used in those treatments where strong bone fixation is required, as it may provide[1]:
The S2-Alar-Iliac technique represents a valid solution since the medial entry points reduce the need of muscle dissection leading to[5]:
*compared with alternative lumbosacral instrumentations (S2-Alar and Iliac screws)
Prominent conventional Iliac screws may lead to irritation and pain with high revision rate.[2,5]
MYSPINE IS DIFFERENT!
MySpine guided S2-Alar-Iliac trajectory may allow for a small incision and less lateral retraction, and the medial entry point allows for a quick rod connection, thus eliminating the need for additional connectors.[5]
The guided technique leads to precise screw placement, comparable to that offered by gold standard navigation tools, while reducing the radiation exposure and the surgical time.[3,4]
MySpine is a personalized surgical platform that is cost effective, efficient and intuitive. MySpine provides pre-op planning, single-use patient-specific drill guides and intra-operative surgical plan.
