A system for minimally invasive spine surgery includes a plurality of bone anchors, a spinal rod, a plurality of dilators of differing lengths and diameters, and a surgical access port. The surgical access port includes a proximal end, a distal end, and a sidewall defining a lumen extending from the proximal end to the distal end. The port may include a first opening formed in the sidewall that defines a passageway for medical hardware from the lumen to external to the port. The system can include first instrument for creating a subcutaneous pathway from the opening in the port.

1. A system for minimally invasive spine surgery comprising: a plurality of bone anchors configured for implantation in a vertebra;a spinal rod configured to connect one bone anchor of the plurality of bone anchors implanted in a first vertebra with a second bone anchor of the plurality of bone anchors implanted in a second vertebra;a plurality of dilators of varying lengths and diameters;a first surgical access port comprising a proximal end, a distal end spaced apart a distance from the proximal end, and a sidewall defining a lumen extending from the proximal end to the distal end, the lumen having a length sufficient to at least span from a skin incision to proximate a vertebra and a diameter greater than the diameters of the plurality of dilators, the first surgical access port having a first opening formed in the sidewall, the first opening defining a passageway for medical hardware from the lumen to external to the first surgical access port;a second surgical access port comprising a proximal end, a distal end spaced apart a distance from the proximal end, and a sidewall defining a lumen extending from the proximal end to the distal end, the lumen having a length sufficient to at least span from a skin incision to proximate a vertebra and a diameter greater than the diameters of the plurality of dilators, the second surgical access port having a first opening formed in the sidewall, the first opening defining a passageway for medical hardware from the lumen to external to the second surgical access port;a first instrument for creating a subcutaneous pathway from the opening in the first surgical access port to the opening in the second surgical access port, the first instrument having a distal end sized to pass through the opening in first surgical access port and extend from the subcutaneously from a first vertebra to a second vertebra, anda second instrument having a distal end sized to pass through the opening in the second surgical access port and configured to engage the distal end of the first instrument. 2. The system of claim 1, wherein the second instrument further comprises a proximal handle, a shaft having a longitudinal axis, the shaft being sized to fit through the lumen of the second surgical access port and wherein the distal end of the second instrument is oriented at angle to the shaft and is sized to receive at least a portion of the distal end of the first instrument therein. 3. The system of claim 1, wherein the spinal rod has a tip configured to dissect tissue. 4. The system of claim 1, wherein the first instrument comprises a proximal handle, a shaft having a longitudinal axis, the shaft being sized to fit through the lumen of the port and wherein the distal end is oriented at angle to the shaft. 5. The system of claim 4, wherein the distal end is oriented approximately perpendicular to the longitudinal axis of the shaft. 6. The system of claim 4, wherein the distal end is sharpened sufficiently to dissect tissue. 7. A system for minimally invasive spine surgery comprising: a plurality of bone anchors configured for implantation in a vertebra;a spinal rod configured to connect one bone anchor of the plurality of bone anchors implanted in a first vertebra with a second bone anchor of the plurality of bone anchors implanted in a second vertebra;a plurality of dilators of varying lengths and diameters;a first surgical access port comprising a proximal end, a distal end spaced apart a distance from the proximal end, and a sidewall defining a lumen extending from the proximal end to the distal end, the lumen having a length sufficient to at least span from a skin incision to proximate a vertebra and a diameter greater than the diameters of the plurality of dilators, the first surgical access port having a first opening formed in the sidewall, the first opening defining a passageway for medical hardware from the lumen to external to the first surgical access port;a second surgical access port comprising a proximal end, a distal end spaced apart a distance from the proximal end, and a sidewall defining a lumen extending from the proximal end to the distal end, the lumen having a length sufficient to at least span from a skin incision to proximate a vertebra and a diameter greater than the diameters of the plurality of dilators, the second surgical access port having a first opening formed in the sidewall, the first opening defining a passageway for medical hardware from the lumen to external to the second surgical access port;a first instrument for creating a subcutaneous pathway from the opening in the first surgical access port to the opening in the second surgical access port, the first instrument having a distal end sized to pass through the opening in first surgical access port and extend from the subcutaneously from a first vertebra to a second vertebra, the first instrument having a proximal handle, a shaft having a longitudinal axis, the shaft being sized to fit through the lumen of the port and wherein the distal end is oriented at angle to the shaft; anda second instrument having a distal end sized to pass through the opening in the second surgical access port and configured to engage the distal end of the first instrument, the second instrument having a proximal handle, a shaft having a longitudinal axis, the shaft being sized to fit through the lumen of the second surgical access port and wherein the distal end of the second instrument is oriented at angle to the shaft and is sized to receive at least a portion of the distal end of the first instrument therein. 8. The system of claim 7, wherein the distal end is oriented approximately perpendicular to the longitudinal axis of the shaft. 9. The system of claim 7, wherein the distal end is sharpened sufficiently to dissect tissue.
