Hyaluronic acidhyaluronic acid (20 mg/2 mL)1mL of hyaluronic acid (20 mg/2 mL; Hyalgan, Fidia, Abano Terme, Italy) infiltration at A1-Pulley under ultrasound guidance after subcutaneous 2% lidocaine without epinephrine infiltration of the skin overlying the A1-pulley.
Triamcinolone acetonideTriamcinolone acetonide 10mg/ml1 mL of Triamcinolone acetonide 10mg/ml infiltration at A1-Pulley under ultrasound guidance after subcutaneous 2% lidocaine without epinephrine infiltration of the skin overlying the A1 pulley.
Primary Outcome Measures
NameTimeMethod
Change in Quinnell trigger finger grading system:1 and 3 months post-injection

Change in Quinnell grading overtime within 3 months after injection. Trigger fingers are rated as follows: Grade 0: normal finger movements, Grade 1: uneven finger movements, Grade 2: actively correctable triggering, Grade 3: passively correctable triggering, and Grade 4: locked digit.

Secondary Outcome Measures
NameTimeMethod
Changes in Grip strength1 and 3 months post-injection

Measured by the dynamometer strength test (Jamar grip dynamometer)

The Quick Disability of the Arm, Shoulder and Hand score1 and 3 months post-injection

Patients will be asked to fill a questionnaire form. It is an 11-item form that assesses the upper limb function on a scale of 1-5, with scores ranging from 11 to 55, with the higher scores representing more disability and worse upper limb function.

Visual analogue scale (VAS) of pain1 and 3 months post-injection

Change in pain Visual analogue scale will be recorded. The patient marks on the 100 mm in length line the point that he/she feels to represent his/her perception of pain at the current state. The VAS score is determined by measuring in millimetres from the left hand end of the line to the point that the patient marks ( a higher score indicates greater pain intensity). Categorization of none, mild, moderate and severe pain will be also used (none = 0, mild = 1-4, moderate = 5-6, and severe = 7-10).

Frequency of tender trigger nodules1 and 3 months post-injection

Identifying the presence of tender nodules at A1-pulley of the affected finger by palpation

Patient satisfaction with therapy1 and 3 months post-injection

Participating patients will be asked to classify their result into 1 of 4 categories: (1) complete resolution of symptoms, (2) improved result, but incomplete resolution of symptoms, not warranting further treatment, (3) partial response, but unsatisfactory, warranting further treatment, and (4) no response.

Ultrasound evaluation of A1-Pulley1 and 3 months post-injection

Detailed ultrasonography evaluation of A1-Pulley. Comparing the A1-Pulley ultrasonographic parameters over 3 months after injection (at the follow-up appointment)
