Inject betamethasone by sonography
Inject betamethasone directly
Use 5/8 in medical needles inject betamethasone 7mg (1ml) in distal wrist crease by sonography- guided. Entering skin with 30 degrees from the ulnar side of palmaris longus tandon. Changing direction of injection to prevent median nerve injury if patients feel numbness or pain in hand.
