Spine Surgery: Sextant Minimally Invasive Fusion (Medtronic)


Minimally invasive surgery of the spine allows minimal tissue disruption and decreased muscle dissection, while at the same time accomplishing decompression and fusion of the spine.  One very useful device and technique which enables the minimally invasive accomplishment of a spinal fusion is the Sextant device (Medtronic).  This device allows the spine surgeon to place screws into the spine in a percutaneous manner (through the skin), and then place a rod percutaneously, which will connect the screws and allow for fusion of the adjacent levels.

Below, the Sextant device (Medtronic) is seen.  Each of the long tubes will be attached in a minimally invasive percutaneous manner, to the screws in the spine.  The arc or sextant device (Medtronic) is then attached to the tubes, and a rod, which is connected to the arc, is passed, through the skin, into the head of the screws, enabling a completely percutaneous fusion of the spine.

Below, a schematic of the spine is seen.  Using c-arm (flouroscopy) x-ray imaging, the surgeon places a Jamshidi needle into the spine.  Specifically, the surgeon places the Jamshidi into the pedicle of the spine.

Above, a tap is seen being placed into the pedicle.  This will allow threads to be placed in the bone of the pedicle.  Subsequently, a screw will be placed.

Above, the sextant device (Medtronic) is seen, attached to the pedicle screws which have been implanted into the spine.  The arc of the sextant is seen, ready to pass a rod toward the pedicle screws.

Above, a rod is seen connecting the two pedicle screws.  It has been placed in a minimally invasive percutaneous manner, using the medtronic sextant device.

minimally invasive percutaneous fusion

When a minimally invasive percutaneous device (sextant, medtronic) is used, several punctate incisions are used to place the screws and the rods.  As seen above, these are easily closed with suture, staples, or dermabond (glue).
