Obese people benefit from lumbar spinal stenosis surgery: St
Lumbar spinal stenosis (LSS) is a common degenerative condition of the spine that causes back pain radiating to the lower extremity. Surgical treatment is indicated to treat progressive radical symptoms. This paper aims to identify whether obesity affects QoL due to back pain among patients who underwent an operation for LSS.

Operated patients who returned for follow-up forms within the first or second years were included. A total of 359 patients were selected, 163 males and 196 females. The mean age was 68.9?years. The EuroQol five-dimension scale (EQ-5D) questionnaire was chosen to measure QoL and the Oswestry Disability Index (ODI) for functional disability.

Results:
--QoL, as measured by EQ-5D, was preoperatively lower in those patients with a BMI more than 30.

--One year after the operation, all groups had a similar trend of improved QoL.

--At the second year, the results in all groups levelled off even though there was no statistical difference in clinical outcomes.

The ODI was preoperatively statistically higher in patients with a BMI more than 30. 2 years after the surgery, all groups had improved ODI scores, but there was no statistical difference in ODI between the BMI groups.

Conclusively, Surgical intervention should be explored as a therapy option for appropriate patients for weakening or long-lasting symptoms of LSS despite high BMI.
