Background: Prior studies have linked sarcopenia and fat infiltration in paraspinal muscles with lumbar pain, spinal pathology, and adverse postoperative outcomes in lumbar spine surgery. A recent magnetic resonance imaging (MRI)-based method for assessing muscle health, incorporating parameters such as Goutallier Classification (GC) and the Paralumbar Muscle Cross-Sectional Area to Body Mass Index ratio (PL-CSA/BMI), has shown that higher muscle grades correlate with significant improvements in patient-reported outcomes. Despite these advancements, there is limited research on the associations between paralumbar muscle health and factors such as age, BMI, walking tolerability, and spondylolisthesis.

- The study investigates the relationship between lumbar spine surgery history and paralumbar muscle health as assessed through MRI measurements.
- It employs a retrospective cohort design, comparing MRI-based parameters like cross-sectional area and muscle grading between patients who have undergone spine surgery and those who haven’t.
- Analysis involved 615 patients, ultimately matching 89 patients with surgery history to 89 without, showing no significant differences in demographic variables.
Purpose: Adult Spinal Deformity (ASD) includes a spectrum of spinal conditions that can be associated with significant pain and loss of function. While 3-column osteotomies have been the procedures of choice for ASD patients, there is also a substantial risk for complications. The prognostic value of the modified 5-item frailty index (mFI-5) for these procedures has not yet been studied.

- The study aimed to explore the relationship between the duration of back pain symptoms (more than or less than 12 weeks) and the volume of paralumbar muscles in patients.
- Using data from 551 patients and various imaging techniques, researchers assessed paralumbar muscle volume and found no significant differences between patients with short-term vs. long-term symptoms.
- The conclusions suggest that the length of back pain symptoms may not accurately indicate lumbar muscle volume, which could lead to reevaluation of treatment options for patients with chronic pain.
