LAT Interbody Fusion Approach Portfolio

Question 1

Posterior Approach - GOOD vs. BAD

Answer 1

GOOD: Anterior graft placement allows for secondary fusion, secure pedicle screw fixation and spinal manipulations
BAD: Significant muscle disruption, post-op recovery times & limited graft size. Have to resect bone and retract neural structure

Question 2

Optimal Conditions for Lat Approach

Answer 2

1. Access to L1-L5 disc spaces
2. Post-Diskectomy DDD
3. Adjacent Level DDD
4. Degenerative Scoliosis
5. Grade 1 Spondylosisthesis

Question 3

Lat Approach - Good vs Bad

Answer 3

1. GOOD - Direct visualization of disc space allows placement for a LARGE graft - minimal muscle disruption
2. BAD - Approach is difficult in overweight patients. Risk to abdominal viscera and great muscles. Requires an ACCESS Surgeon.
