The efficacy of combined popliteal and ankle blocks in forefoot surgery.
BACKGROUND
Postoperative pain following forefoot surgery can be difficult to control with oral analgesia. The aim of this study was to compare the efficacy of a combined popliteal and ankle block with that of an ankle block alone in providing postoperative analgesia following forefoot surgery.


METHODS
We performed a prospective, randomized, controlled single-blind study involving sixty-three patients, twenty-six of whom had a combined ankle and popliteal block and thirty-seven of whom had an ankle block alone. All patients underwent an elective osseous surgical procedure on the forefoot. Postoperative pain was evaluated with use of a visual analogue scale and a verbal response form. Patient satisfaction was also recorded.


RESULTS
The patients who had had a combined popliteal and ankle block had significantly less pain at six hours postoperatively (p = 0.011), twenty-four hours postoperatively (p < 0.001), and at discharge (p = 0.014). This group of patients also had higher satisfaction with pain relief.


CONCLUSIONS
A popliteal block in conjunction with an ankle block provides significantly better pain relief than does an ankle block alone in patients undergoing forefoot surgery.
