Neuropathic pain after orthopaedic surgery with continuous peripheral nerve block.

Introduction: Continuous peripheral nerve blocks (cPNBs) have shown favourable post-operative pain control results but may be associated with a risk for long-term neurological complications. This study sought to examine factors associated with persistent post-operative pain and potential neuropathy after orthopaedic lower-limb surgery with the use of post-operative cPNB.

Methods: Patients who underwent lower limb orthopaedic procedures with cPNBs between November 2021 to May 2022 were included.
