Article Synopsis
- A retrospective cohort study was conducted to evaluate the effects of different lumbar fusion surgeries on postoperative paraspinal muscles, focusing on muscle density and cross-sectional area changes using CT imaging.
- The study included 62 female patients, comparing outcomes between those who had traditional open posterior lumbar interbody fusion (PLIF) and those who received a minimally invasive approach with lateral lumbar interbody fusion (LLIF) followed by percutaneous pedicle screws (PPS).
- Results indicated that while no decrease in muscle cross-sectional area was noted, the multifidus muscle density significantly decreased at one year post-surgery only in the PLIF group, suggesting that the LLIF/PPS approach may better preserve paraspinal muscle integrity.
