Trial summary
Trigger finger is a common disease of the hand involving swelling and inflammation of the tendon which flexes a finger, causing catching, locking, and/or pain. Trigger finger is typically treated by hand surgeons with a steroid injection through the front/palm side of the hand into the area near the tendon (i.e., at… Read more about this study

About this study
Official title: Trigger Finger Corticosteroid Injection Pain: Palmar Injection Versus Dorsal Intrasynovial (Transthecal) Injection
Trigger finger is a common disease of the hand involving swelling and inflammation of the tendon which flexes a finger, causing catching, locking, and/or pain. Trigger finger is typically treated by hand surgeons with a steroid injection through the front/palm side of the hand into the area near the tendon (i.e., at the base of the affected finger). This steroid injection is often combined with a local anesthetic (numbing agent) to help reduce short-term pain from the injection. However, the front/palm side of the hand is known to be very sensitive, and the steroid injection can be quite painful as the needle pierces the front/palm skin.
To reduce the pain of steroid injections for trigger finger, a different approach involves performing the injection from the back/dorsal side of the hand, which is thought to be less sensitive (and therefore less painful) than the front/palm side of the hand. This technique is sometimes used and has been previously studied, but it is not clear if it can offer less injection-related pain than standard treatment.
Accordingly, this study will be comparing short-term injection-associated pain between front/palm side and back/dorsal side steroid injections for trigger finger. The study will also seek to understand what area of the hand is numbed by the anesthetic when doing a front/palm side injection versus a back/dorsal side injection of the hand. Overall, the investigators hypothesize that back/dorsal side injections will be less painful than front/palm side injections for trigger fingers and that the area of numbing from the anesthetic will be equivalent between both types of injections.
Read the detailed description
Trigger finger (stenosing tenosynovitis) is one of the most common pathologies assessed by hand surgeons in clinic. Trigger finger involves inflammation or edema of the flexor tendon causing friction of the tendon at the site of the A1 annular pulley located at the base of the affected finger in the palm. Trigger finger is typically managed non-surgically in a clinic setting with percutaneous corticosteroid injection (CSI) which can be successful in alleviating symptoms. Patients with trigger finger who do not respond to CSI, have incomplete relief, and/or who have recurrent symptoms may then receive surgical management with release of the A1 pulley.
CSIs for trigger fingers are among the most common procedures performed by hand surgeons and are often administered multiple times in a single clinic day. CSIs are frequently mixed 50:50 with 1% lidocaine to provide post-injection analgesia for patients as well as symptomatic relief of the trigger finger if acutely inflamed. These injections are commonly administered from a palmar approach into the A1 pulley of the affected digit. Numerous technical variations of palmar trigger finger injections have been described involving either subcutaneous injection superficial to the flexor tendon sheath or intrasynovial (transthecal) injection into the flexor tendon sheath.
Unfortunately, given the rich sensory innervation of the palmar skin, palmar injections are associated with significant pain as the needle pierces the skin. An alternative technique is to provide digital anesthesia from a dorsal webspace approach, injecting the local anesthetic into the flexor tendon synovial sheath. This intrasynovial or transthecal technique has the benefit of a dorsal approach where the skin is less sensitive resulting in less pain (6). This technique has been described previously but is not familiar to many hand surgeons and is not routinely used in North America.
Anecdotally, patients report significantly decreased pain with the dorsal intrasynovial injection technique for trigger finger injections, but pain scores have not been quantitatively evaluated or compared to the pain scores of traditional palmar trigger finger injections. Furthermore, it is not known what distribution of digital sensory blockade is achieved with this intrasynovial technique, particularly on the dorsal surface of the digit which is discontinuous with the flexor tendon sheath and innervated by the sensory branch of the radial nerve.
Accordingly, it is hypothesized that injecting corticosteroids into the synovial sheath of the flexor tendon will result in less pain over 24 hours if performed through the dorsal webspace versus the palmar side of the affected digit.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Dorsal webspace combined corticosteroid and anesthetic injectionProcedure or surgery
The dorsal webspace injection consists of a 1cc mixture of 0.5cc triamcinolone (Kenalog) 10mg/mL and 0.5cc 1% lidocaine for analgesic purposes.
Palmar combined corticosteroid and anesthetic injectionProcedure or surgery
The palmar injection consists of a 1cc mixture of 0.5cc triamcinolone (Kenalog) 10mg/mL and 0.5cc 1% lidocaine for analgesic purposes.
| Study group | Role | What they receive |
|---|---|---|
| Dorsal Webspace Approach | Experimental | A dorsal approach involves passing the needle with a 1:1 triamcinolone and lidocaine mixture in the dorsal webspace skin aiming just palmar to the proximal phalanx bone such that the needle is directed into the flexor tendon sheath at the A1 annular pulley. Receives: Procedure: Dorsal webspace combined corticosteroid and anesthetic injection |
| Palmar Approach | Active comparator | Standard approach for injecting the 1:1 triamcinolone and lidocaine mixture involves the needle passing through the cutaneous and subcutaneous layers of the palmar skin surface and into the flexor tendon sheath at the A1 annular pulley. Receives: Procedure: Palmar combined corticosteroid and anesthetic injection |
What is being measured
The primary outcome is the main question the study is designed to answer.
Visual Analogue Scale (VAS) - Pain
100mm mechanical rating scale for pain, ranging from 0mm ("no pain") to 100mm ("pain as bad as it could be"); higher scores indicate a worse outcome.
Measured: measured at 0 hours, 4 hours, and 24 hours post-injection
Numerical Rating Scale (NRS) - Pain
11-point numerical rating scale for pain, ranging from 0 (no pain) to 10 (worst pain ever possible); higher scores indicate a worse outcome.
Measured: measured at 0 hours, 4 hours, and 24 hours post-injection
Short-Form McGill Pain Questionnaire (SFMPQ) - Present Pain Intensity (PPI)
5-point combined numerical-word rating scale for pain, ranging from 1 (mild) to 5 (excruciating); higher scores indicate a worse outcome.
Measured: measured at 0 hours, 4 hours, and 24 hours post-injection
Secondary outcomes (2)
Sensory Assessment - Light Touch
Semmes-Weinstein 2.0g monofilament test as threshold of sensory impairment
Measured: measured at 0 hours post-injection

Questions about this trial
What is this clinical trial studying?
A study testing Dorsal webspace combined corticosteroid and anesthetic injection and Palmar combined corticosteroid and anesthetic injection in people with Trigger Finger Disorder, run by Kevin Zuo at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 19 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
