From the Research

Trigger Point Injection Needle Size

  • The recommended needle size for Trigger Point (TP) injection is not explicitly stated in the provided studies 1, 2.
  • However, studies on percutaneous trigger finger release provide information on needle sizes used for similar procedures:
    • A 21-gauge hypodermic needle was used for percutaneous release of the trigger finger 3.
    • An 18-gauge needle with a blade at the tip was used for ultrasound-guided microinvasive trigger finger release 4.
    • A specially designed needle (0.8×100 mm) with a planus tip was used for percutaneous trigger thumb release 5.
  • These studies suggest that needle sizes ranging from 18-gauge to 21-gauge may be used for similar procedures, but the optimal needle size for TP injection is not specified 4, 3, 5.
