RATIONALE

The distal fixation in thoracolumbar deformity surgery can be challenging for spine surgeons. When isolated S1-pedicle screws are utilized as the sole distal fixation in long thoracolumbar posterior constructs, there is a high rate of failure, due to loosening, breakage, and pseudarthrosis[2]. Unfortunately, with iliac screw fixation the entry point at the posterior superior iliac spine requires considerable soft tissue dissection and may potentially increase the likelihood of wound complications.[3]

S2-Alar-Iliac (S2AI) screw fixation technique was developed recently to provide increased fixation with a lower profile screwand rod construct[1]. This technique may provide advantages such as decreased rates of reoperation, surgical site infection,wound dehiscence and symptomatic screw prominence as compared to traditional iliac screw fixation.[3]

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 MySpine S2AI patient-specific drill guide might help facilitating complex thoracolumbar fixation with minimal radiation exposure and high accuracy.[3,4]
