Spinal implant system and method for lumbar and lumbosacral fusion

A surgical instrument comprising:

• a handle;
• a posterior blade connected with the handle and extending along a first longitudinal axis, the posterior blade being connected to the handle by a first pin that extends parallel to the first longitudinal axis, the posterior blade comprising a recessed track having a first section and a second section extending at a right angle relative to the first section, the second section being in communication with the first section, the first pin being received in the second section, the posterior blade being rotatable relative to the handle about the first longitudinal axis;
• an anterior blade connected with the handle and extending along a second longitudinal axis that extends parallel to the first longitudinal axis, the anterior blade being connected to the handle by a second pin that extends parallel to the second longitudinal axis, the second pin being received in a recess of the anterior blade, the anterior blade being rotatable relative to the handle about the second longitudinal axis, the blades being rotatable relative to one another about a pivot axis that extends parallel to the first and second longitudinal axes;
• and
• a cephalad blade connected with the handle,
• wherein the blades are disposable in a configuration to space tissue of an incision to define an oblique surgical pathway relative to a bilateral axis of a body.

A surgical instrument comprising:

• a handle having a first arm comprising a first pin, a second arm comprising a second pin and a third arm comprising a third pin, the first and second arms being rotatable relative to one another about a pivot axis, the third arm being slidable relative to the first arm and the second arm;
• a posterior blade extending along a first longitudinal axis and comprising a first recessed track having a first section and a second section extending at a ninety degree angle relative to the first section, the second section being in communication with the first section, the first pin being received in the second section to couple the posterior blade to the handle, the posterior blade being rotatable relative to the first pin about the first longitudinal axis;
• an anterior blade extending along a second longitudinal axis and comprising a second recessed track having a first section and a second section extending at a ninety degree angle relative to the first section of the second track, the second section of the second track being in communication with the first section of the second track, the second pin being received in the second section of the second track to couple the anterior blade to the handle, the anterior blade being rotatable relative to the second pin about the second longitudinal axis;
• and
• a cephalad blade positioned between the posterior blade and the anterior blade, the cephalad blade defining a third longitudinal axis, the cephalad blade comprising a third recessed track having a first section and a second section extending at a ninety degree angle relative to the first section of the third track, the second section of the third track being in communication with the first section of the third track, the third pin being received in the second section of the third track to couple the cephalad blade to the handle, the cephalad blade being rotatable relative to the third pin about the third longitudinal axis,
• wherein the blades are disposable in a configuration to space tissue of an incision to define an oblique surgical pathway relative to a bilateral axis of a body.
