Medial Forefoot Block for Analgesia After Foot Surgery

This study has been completed.

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.

Condition Intervention
Hallux Valgus
Procedure: Landmark guided ankle block.
Procedure: PNS guided block.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomised, Blinded Comparison of a Nerve Stimulator Guided Ankle Block Compared to a Landmark Guided Ankle Block for Pain Relief After Forefoot Surgery.

Further study details as provided by Dr. Andrew J Coe, Hull and East Yorkshire Hospitals NHS Trust:

Primary Outcome Measures:
  • Efficacy of local anaesthetic block. [ Time Frame: Over ninety minutes from the start of the study. ]
    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.

Secondary Outcome Measures:
  • Intravenous opiate usage following surgery [ Time Frame: 24 hours following surgery ]
    The usage of intravenous morphine, delivered by a ptient controlled analgesia system, in each group was recorded.

Enrollment: 72
Study Start Date: March 2007
Study Completion Date: March 2009
Primary Completion Date: March 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Landmark guided ankle block
This group will receive a landmark guided ankle block.
Procedure: Landmark guided ankle block.
25-30mls 0.5% levobupivacaine will be infiltrated to provide a landmark guided ankle block.
Other Name: Other names not required
Active Comparator: This group will be given a PNS guided ankle block
Peripheral nerve stimulation will be used in this group to guide local anaesthetic infiltration. The technique is termed medial forefoot block.
Procedure: PNS guided block.
This group will have 25-30mls of 0.5% levobupivacaine infiltrated as directed by peripheral nerve stimulation.
Other Name: Other names not required
