Brief Summary

Trigger finger, also known as trigger digit or stenosing tenovaginitis, is caused by a size mismatch between the flexor tendon and the A1 pulley, which is generally characterized by pain, swelling, the limitation of finger range of motion and a symptomatic locking or clicking sensation. Conservative treatment options include the application of non-steroidal anti-inflammatory drugs (NSAID), physiotherapy, electrotherapy, splinting and corticosteroid injection but not always effective with regard to frequent recurrence. Open surgical release of the A1 pulley remains the gold standard of treating symptomatic trigger finger. While percutaneous release is a minimal invasive alternative and gaining popularity for the index, middle ring and little fingers, investigations for the surgical efficacy on thumb is few and far between. Investigators believe that a carefully conducted operation with proper positioning of the thumb, wide-awake approach and meticulous technique can achieve similar efficacy and safety in terms of possibly less intraoperative pain, imperceptible scar and early return to daily activities and routine work. The hypothesis of this study is that by using a proper positioning of thumb, wide awake approach and meticulous technique in conducting percutaneous release of trigger thumb can achieve similar efficacy and safety compared to that of open release surgical method. Moreover, percutaneous release of trigger thumb can generate less intraoperative pain, imperceptible scar and promote early return to routine work. Hence, the objective of this study is to investigate and compare the safety, effectiveness and outcome of percutaneous release versus traditional open release for trigger thumbs.

Outcome Measures

Primary Outcomes (26)

  • Total volume of local anaesthetics injected

    The total volume of local anaesthetics injected during operation

    Intra-operative

  • Duration of surgery (in minutes)

    The time (in minutes) needed for operation

    Intra-operative

  • Surgical site pain

    Visual analogue scale (VAS) was used to evaluate the pain at surgical site (0=no pain and 10=greatest pain)

    Intra-operative

  • Active and passive range of motion (ROM) of interphalangeal joint (IPJ) and metacarpal-phalangeal joint (MPJ)

    Pre-operative active and passive ROM of IPJ and MPJ was measured to determine the joint stiffness

    Pre-operative

  • Active and passive range of motion (ROM) of interphalangeal joint (IPJ) and metacarpal-phalangeal joint (MPJ)

    Active and passive ROM of IPJ and MPJ was measured post-operatively to determine the joint stiffness

    Post-op Day 7

  • Active and passive range of motion (ROM) of interphalangeal joint (IPJ) and metacarpal-phalangeal joint (MPJ)

    Active and passive ROM of IPJ and MPJ was measured post-operatively to determine the joint stiffness

    Post-op Day 28

  • Active and passive range of motion (ROM) of interphalangeal joint (IPJ) and metacarpal-phalangeal joint (MPJ)

    Active and passive ROM of IPJ and MPJ was measured post-operatively to determine the joint stiffness

    Post-op Day 90

  • Pre-operative Kapandji score

    Kapandji score is a tool useful for assessing the opposition of the thumb, based on where on their hand the patient is able to touch with the tip of their thumb.

    Pre-operative

  • Post-operative Kapandi score

    Kapandji score is a tool useful for assessing the opposition of the thumb, based on where on their hand the patient is able to touch with the tip of their thumb.

    Post-op Day 7

  • Post-operative Kapandi score

    The disabilities of the arm, shoulder and hand (DASH) questionnaire is a self-administered region-specific outcome instrument developed as a measure of self-rated upper-extremity disability and symptoms. The DASH consists mainly of a 30-item disability/symptom scale, scored 0 (no disability) to 100.
