How patients were doing one year after lateral lumbar fusion, a minimally invasive approach through the side
Lateral lumbar interbody fusion: clinical and radiographic outcomes at 1 year: a preliminary report
In simple words
Lateral lumbar fusion joins vertebrae through a small cut in the side of the body instead of the back. At one year it straightened sideways curves and improved the inward curve at each fused level, and patients' scores for pain and function improved.
What the study looked at
The records and X-rays of 43 consecutive patients who had lateral lumbar fusion (87 spinal levels) for disc degeneration, a slipped vertebra or adult scoliosis, followed for about a year.
What it found
Each fused level gained around 3.7° of sideways correction and 2.8° of inward curve (lordosis). In the 25 patients with scoliosis, the curve improved by about 10° (43%) on average. Temporary thigh pain was the most common side effect (about 1 in 4 patients), and outcome scores improved.
Why it matters for patients
Lateral fusion can correct alignment through a smaller approach. Thigh discomfort after surgery is common but usually settles. The authors called for larger, longer studies.
