Design outcomes

Primary

MeasureTime frame
Onset time of sensory block in the tibial nerve and common peroneal nerve.;The sensory and motor function in the ipsilateral foot will also be evaluated by an independent observer (research nurse) at regular intervals for 50 minutes (5 min, 10 min, 20 min, 30min, 40 min and 50 min) after the sciatic nerve block.;

Secondary

MeasureTime frame
The incidence of paresthesia, abnormal sensation and motor weakness will be followed up at 1 week and 1 month after the surgery;
