Objectives
Narrative objectives1
Surgery for distal radius fractures (open reduction with palmar locking plate) is often performed with brachial plexus block, but the wound pain may be very strong after the anesthetic effect disappears after surgery. Post-operative pain reduces the satisfaction of patients. Post-operative pain control may be difficult only with non-steroidal anti-inflammatory analgesics and opioids as analgesics, and countermeasures are required. Continuous brachial plexus block is useful for analgesic purposes, but it is a proximal block, which may limit patient activity or cause anxiety due to postoperative paralysis of the upper limbs. It is desirable to perform the minimum necessary blocks.
The wound pain after orthopedic surgery is thought to have mainly originated from the periosteum. In surgery for distal radius fractures, the wound pain of the periosteum (the part to which the locking plate is fixed) on the distal radius side is considered to be the main subject. It is thought that the anterior interosseous nerve, which is a branch of the median nerve, is governed as a sensory nerve at this site, and it has been reported that this nerve block is useful for periosteal pain in wide-awake hand surgery, However, there are no reports using an anterior interosseous nerve block for analgesia after distal radius fracture surgery.
In this study, we evaluate the efficacy of an anterior interosseous nerve block performed at the end of surgery for the time to the first analgesic after surgery as the primary outcome for the distal radius fracture. The improvement of pain score and patient satisfaction is set as secondary outcomes. Since there is no previous study and it is impossible to calculate the sample size, the pilot study will be conducted in 20 cases.
