Forefoot surgery includes bunion surgery and similar reconstructive bone cutting surgery and is very painful. Local anaesthetic nerve blocks are used to provide pain relief after this work. The purpose of this study is to compare two techniques: one using anatomical landmarks alone to guide local anaesthetic infiltration, the other using peripheral nerve stimulation to guide local anaesthetic infiltration (termed medial forefoot block). The two techniques will be compared for reliability of postoperative analgesia.

25-30mls 0.5% levobupivacaine will be infiltrated to provide a landmark guided ankle block.
This group will have 25-30mls of 0.5% levobupivacaine infiltrated as directed by peripheral nerve stimulation.

Efficacy of local anaesthetic block.
The number of patients in each study arm with altered sensation to cold and pin prick, together with no requirement for opiate analgesia, following surgery was recorded.
Time frame: Over ninety minutes from the start of the study.
Intravenous opiate usage following surgery
The usage of intravenous morphine, delivered by a ptient controlled analgesia system, in each group was recorded.
Time frame: 24 hours following surgery
