Key result
Intermittent claudication with a waking distance ≤ 100 m was strongly associated with an increased risk of failed back surgery syndrome (OR 12.43) following open posterior lumbar surgery.
Why the study?
With the growing number of traditional posterior open surgeries, the incidence of failed back surgery syndrome is increasing, prompting investigation into its incidence and risk factors.

Lower preoperative leg pain, hypertension, intermittent claudication, high intensity zone, Modic changes, and postoperative rehabilitation are independent risk factors for failed back surgery syndrome after open posterior lumbar surgery.

May aid risk stratification in lumbar surgery candidates; leaves open whether modifying identified factors reduces FBSS rates.
Xu et al. (2022) conducted a cohort in Degenerative lumbar disease (n=333). Intermittent claudication with waking distance ≤ 100 m vs. No intermittent claudication was evaluated on Failed back surgery syndrome (FBSS) (OR 12.43, 95% CI 5.54-27.92, p=<0.001). Intermittent claudication with a waking distance ≤ 100 m was strongly associated with an increased risk of failed back surgery syndrome (OR 12.43) following open posterior lumbar surgery.
