Following the publication of the original article [1] the authors reported an error in the 2nd paragraph of section “Study population”.

“Their mean age at surgery was 60.8 ± 10.3 years and the average symptom duration was 40.7 ± 34.1 months.”

Should be corrected to:

“Their mean age at surgery was 61.2 ± 10.8 years and the average symptom duration was 23.36 ± 22.11 months.”
