Anatomy
The flexor retinaculum attaches to four areas. Namely the pisoform, the scaphoid, the hook of the hamate, and the trapezium. The proximal edge lies at the distal wrist crease. The median nerve normally lies under the palmaris longus tendon (if present) at the mid wrist, and is medial to the flexor carpi radialis (FCR) tendon. The FCU attaches to the pisiform. The distal wrist crease crosses the pisiform
Indications and Efficacy
- Injection for Carpal Tunnel Syndrome.
Contraindications
Pre-procedural Evaluation
The clinician has the choice between various therapeutic agents and/or methods including corticosteroid, dextrose, PRP, low volume, and high volume with hydrodissection.
Corticosteroid versus dextrose: The injection of 5mLs of D5W was more effective than corticosteroid in one RCT.[1] Some authors have reported using 10mLs.[2]
Low volume versus hydrodissection: One RCT found no difference,[3] however the study was criticised for inadequate hydrodissection and unclear methodology.[4]
Equipment
Technique
- Position:Hand palm up
- Needle entry site options
- Identify the point midway along the proximal wrist crease, between the FCR and median nerve.
- Insert the needle then angle proximal to distal at a 45 degree angle.
- Slide distally until it is under the midpoint of the retinaculum (feel it puncture the retinaculum)
- Reposition medially if hit nerve
- Inject as a bolus
- Have patient open and close hand to spread the injectate around the carpal tunnel.
Complications
Mild exacerbation of symptoms immediately or in the hours following injection. Soft tissue atrophy. Ulnar artery injury. Median nerve injury.
Aftercare
Rest for one week. Use a night splint. Repeat injections can be done.
