Optimal Analgesia for Forefoot Surgery

Optimal Analgesia Following Metatarsal Surgery: A Prospective Randomised, Single-Blind Sham-Controlled Trial of Three Strategies

A randomised trial comparing three analgesic strategies for patients undergoing forefoot surgery in a day-surgery setting.

Forefoot surgery, including Scarf-Akin osteotomy surgery for bunion correction, is moderately painful orthopaedic surgery, commonly performed as a day-case procedure. Admission for opiate analgesia constitutes a failure of management and financial disadvantage to the healthcare organisation. The investigators seek to establish which technique will result in the best analgesia out of ankle block, metatarsal block, or a combination of the two. As analgesia constitutes part of a return to function, an additional aim is to determine whether either of these approaches will result in an objective functional benefit to the participants.

The trial seeks to recruit 23 patients into either of 3 groups: Ankle + sham metatarsal; sham Ankle + metatarsal; Ankle + Metatarsal.

Inclusion Criteria:

• Participant is willing and able to give informed consent for participation in the study.
• Male or female, aged 18 years or above.
• Diagnosed with 1st metatarsal pathology requiring surgical correction
• Participant meets the criteria for operative management in our day-surgery unit

Exclusion Criteria:

• Contraindication to general anaesthesia
• Diabetic neuropathy affecting lower limbs
• Peripheral neuropathy affecting lower limbs of any aetiology
• Revision surgery
• Lack of capacity to consent
