Femoral nerve block Intervention in Neck of Femur fracture (FINOF): study protocol for a randomized controlled trial

Background Hip fractures are very painful leading to lengthy hospital stays. Conventional methods of treating pain are limited. Non-steroidal anti-inflammatories are relatively contraindicated and opioids have significant side effects.Regional anaesthesia holds promise but results from these techniques are inconsistent. Trials to date have been inconclusive with regard to which blocks to use and for how long. Interpatient variability remains a problem.
