Day Case Lumbar Fusion Surgery
This article is a retrospective analysis of patients enrolled in a study to evaluate the relationship between paraspinal muscle atrophy and improvement in the Oswestry Disability Index (ODI) after spinal fusion surgery for degenerative lumbar spondylolisthesis (DLS). The study found that fatty infiltration of the erector spinae and multifidus muscles was significantly associated with a decreased likelihood of clinically relevant ODI improvement following surgery. However, no significant association was found for the psoas muscle. The researchers concluded that further research is needed to explore interventions that can mitigate paraspinal muscle atrophy and improve patient outcomes

S: This study demonstrates that FI of the erector spinae and multifidus, is significantly associated with less likelihood of clinically relevant ODI improvement following decompression and fusion. Further research is needed to assess the effect of interventions.

ABSTRACT
STUDY DESIGN: Retrospective analysis of prospectively enrolled patients.
OBJECTIVE: To evaluate the relationship between paraspinal muscle (PM) atrophy and Oswestry Disability Index (ODI) improvement after spinal fusion surgery for degenerative lumbar spondylolisthesis (DLS).
BACKGROUND: Atrophy of the PM is linked to multiple spinal conditions, sagittal malalignment, and increased postoperative complications. However, only limited evidence for the effect on patient-reported outcomes exists.
METHODS: Patients with DLS undergoing decompression and fusion surgery were analyzed. Patients with missing follow-up, no imaging, or inadequate image quality were excluded. The Oswestry Disability Index (ODI) was assessed preoperatively and two years postoperatively. A cross-sectional area of the PM was measured on a T2-weighted Magnetic Resonance Imaging (MRI) sequence at the upper endplate of L4. Based on the literature, a 10-point improvement cut-off was defined as the minimum clinically important difference (MCID). Patients with a baseline ODI below the MCID were excluded. Logistic regression was used to calculate the association between fatty infiltration (FI) of the PM and improvement in ODI, adjusted for age, sex, and body mass index (BMI).
RESULTS: 133 patients were included in the final analysis, with only two lost to follow-up. The median age was 68 years (IQR 62 – 73). The median preoperative ODI was 23 (IQR 17 – 28), and 76.7% of patients showed improvement in their ODI score by at least 10 points. In the multivariable regression, FI of the erector spinae and multifidus increased the risk of not achieving clinically relevant ODI improvement (P=0.01 and P<0.001, respectively). No significant association was found for the psoas muscle (P=0.158).
S: This study demonstrates that FI of the erector spinae and multifidus, is significantly associated with less likelihood of clinically relevant ODI improvement following decompression and fusion. Further research is needed to assess the effect of interventions.
