Forefoot surgery causes postoperative pain which requires strong painkillers. Regional blocks are now increasingly used in order to control postoperative pain especially in the first twenty four hours when the pain is at its worst. We conducted a study to see whether timing of ankle block i.e. before or after application of tourniquet shows any difference in efficacy in postoperative analgesia in first twenty four hours.

A prospective study was conducted between September and March 2011 involving 50 patients. Group A had ankle block after and Group B had block before application of tourniquet. Both group had twenty five patients each. Patients were given assessment forms to chart their pain on Visual Analogue Scale (VAS) at 4hrs and twenty four hours after surgery.

Both groups demonstrated good postoperative pain control. Average pain score at four and twenty fours after surgery was 2.5 and 5 in Group A and 3.5 and 6.1 in Group B respectively. Pain control, both at four and twenty four hours surgery was better in Group A but this was not statistically significant.

Ankle block should be routinely used in forefoot surgery to control postoperative pain. Ankle block before or after the application of tourniquet had comparable pain relief with no statistical difference.
