Background
- This has been found to be a quick, safe, and effective means of pain reduction for hand injuries, including reduction of Boxer's Fractures. [1]
Indications
Contraindications
- Overlying site infection
- Injury requiring close neurologic observation (e.g. Compartment Syndrome)
Equipment Needed
- 10 cc Syringe with a 27 Gauge Needle
- Spare 18 Gauge Needle (to draw up anesthetic)
- Local Anesthetic (e.g. Lidocaine vs Bupivacaine)
- Antiseptic (e.g. Chlorhexidine, Betadine, Rubbing Alcohol)
- Sterile Gloves
- Sterile Drape
- Linear Ultrasound Probe (for ultrasound guided procedure)
- Sterile Ultrasound Prove Cover (for ultrasound guided procedure)
Procedure
- Place the patient's extremity in the supinated position
- Cleanse the skin with chosen antiseptic
- Create a sterile field using your sterile drape
Non-Ultrasound Guided Technique
- In a sterile fashion, apply a small wheel of local anesthetic to the area immediately ulnar to tendon of the Flexor Carpi Ulnaris approximately 2 cm proximal to the wrist crease.
