Transpsoas Approach Nuances.

The transpsoas approach is a powerful tool in correcting adult spinal deformity secondary to the degenerative process. It may be used as a stand-alone construct or in combination with other approaches to correct both coronal and sagittal malalignment. Preoperative planning with careful analysis of full-length 36-in radiographs and an MRI of the lumbar spine is essential in determining the safety and feasibility of this approach. Ultimately the goals of deformity correction must be achieved, and lateral lumbar interbody fusion is a valuable tool that can aid in achieving these goals while minimizing perioperative morbidity.
