RATIONALE

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]:

  • Robust bone anchor and improved pelvic tilt correction in Adult Spine Deformity
  • Spine balance recovery in rigid neuromuscular Adolescent Idiopathic Scoliosis
  • Added value in fixing fractured segments

The S2-Alar-Iliac technique represents a valid solution since the medial entry points reduce the need of muscle dissection leading to[5]:

  • Lower incidence of Sacro-Iliac Joint pain*[5]
  • Small incision[5]
  • Less dissection*[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]

  • HIGH ACCURACY
  • LOW X-RAY RADIATION DOSE
  • LOW PROFILE
