The interbody technique that on average results in the least amount of segmental lordosis.
What is TLIF?
Name of this parameter and what is considered optimal.
What are pelvic tilt and <20 degrees?
The spinal level that is the apex of this degenerative scoliosis (L4-5 fusion).

Name this classification system for cervical deformity.
What is the CSRS-European classification system?
Most commonly performed osteotomy technique for this deformity.
What are multi-level PCOs?
