(HealthDay News) – Patients with diabetes who have longstanding diabetes, poor glycemic control, and use insulin had suboptimal improvements in clinical outcomes after lumbar spine surgery, according to research published March 15 in Spine.
Shinji Takahashi, MD, of the Osaka City University Graduate School of Medicine in Japan, and colleagues compared the characteristics and outcomes of 41 patients with diabetes and 124 patients without diabetes after lumbar spine surgery.
According to the researchers, the final low back pain score (visual analogue scale) was higher in patients with diabetes than those without (29.3 vs. 17.9; P=0.013). Patients with diabetes are more likely to have poor improvements in low back pain if they had diabetes for >20 years (odds ratio [OR], 4.95), hemoglobin A1c >6.5% (OR, 2.37; 95% confidence interval [CI] 0.99–5.70), or used insulin (OR, 2.46; 95% CI, 0.66–9.08).
“A duration of diabetes of more than 20 years or HbA1c of more than 6.5% were independent risk factors for poor improvements in low back pain, whereas a duration of diabetes of more than 20 years or insulin use were independent risk factors for poor improvements in leg numbness,” the authors write.
