Local Ketorolac Injection vs Popliteal Sciatic Nerve Blockade as an Adjuvant to a Spinal Block in Hindfoot Arthrodesis.

Background: Popliteal nerve blocks reduce pain and markedly improve postoperative outcomes during foot and ankle surgery; however, several potential complications may arise from nerve block procedures. The purpose of this study was to investigate local infiltration analgesia with ketorolac as a convenient alternative for pain relief.

Methods: A total of 80 patients scheduled for hindfoot arthrodesis were randomly allocated to one of 2 anesthetic groups: a spinal block augmented with either a popliteal nerve block (n = 40) or local ketorolac and Marcaine infiltration (n = 40).
