Plain English Summary
Background and study aims
Hip fracture is one of the most serious injuries that occur in older people. These fractures are very painful and traditionally require potent analgesia (painkillers), which are effective but have side effects including nausea, vomiting, constipation and confusion. The patient may then refuse treatment and remain in pain, or in some cases remain pain-free if they lie in bed, but struggle when walking. Techniques which directly involve numbing the nerves around the hip have been proposed as an alternative and practical method of reducing pain when moving and at rest. However, no study has evaluated numbing of the main nerve in the leg (called femoral nerve block), its effects on overall pain control, and its acceptability to staff and patients compared with standard analgesia. The aim of this study is to find out whether femoral nerve block controls pain more effectively compared to standard analgesia.
Who can participate?
Patients aged 70 and over with an acute hip fracture.
What does the study involve?
Participants are randomly allocated to be treated with either a femoral nerve block or standard analgesia.
What are the possible benefits and risks of participating?
We expect that femoral nerve block will result in fewer side effects, earlier recovery, shorter length of stay in hospital and improved quality of life for patients suffering with an acute hip fracture. The most commonly reported side effects of the drugs used for the femoral nerve block are: low blood pressure, nausea, anaemia, vomiting, dizziness, headache, fever, procedural pain, back pain, and ‘pins and needles’.
Where is the study run from?
Queens Medical Centre, Nottingham University Hospitals NHS Trust, Nottingham, UK.
When is the study starting and how long is it expected to run for?
January 2012 to December 2012.
Who is funding the study?
Nottingham University Hospitals NHS Trust (UK).

| Scientific title | The FINOF - Femoral nerve-block Intervention in Neck Of Femur fracture study |
| Study acronym | FINOF |
| Study hypothesis | Hip fracture is one of the most serious injuries that occur in older people. These fractures are very painful and traditionally require potent opioid/opioid related analgesia, which although effective, has undesired adverse events. Common side-effects include nausea, vomiting, constipation, and more infrequently, but importantly, delirium. Patient may then refuse treatment and remain in pain or in some cases find if they lie in bed, remain pain-free, but struggle during ambulation. This leads to further complications, impaired rehabilitation and prolonged hospital stay. Techniques which directly involve numbing the nerves around the hip, have been proposed as an alternative and practical method of alleviating both rest and dynamic pain (important when patients are being transferred or ambulating). However no study has evaluated numbing of the main nerve in the leg (femoral nerve) and the effects on overall pain control, rehabilitation and issues of compliance, acceptability to staff / patients compared to standard analgesic regimes. We plan to undertake a 12 month randomised controlled study of 150 elderly patients admitted with an acute hip fracture. Subjects on admission, following informed consent will be randomly allocated to a nerve block, followed by a continuous nerve block infusion or standard analgesic care. We envisage nerve block analgesia compared to conventional analgesia will result in fewer drug related adverse events, earlier recovery, shorter length of stay in hospital and overall, improved quality of life for patients suffering with an acute hip fracture. Acceptability and implementation will be measured by semi-structured interviews with both staff and patients focusing around pain (patient group) and ease of use (staff group) which will help the implementation of these findings across the country.
