Ever go to make a fist, and one finger just… stalls? Maybe it clicks, maybe it locks halfway, and you have to use your other hand to pop it straight again. That’s not your imagination, and it’s not arthritis creeping in. It’s most likely a trigger finger, and if you’re dealing with it, it’s one of the more common hand conditions we treat here at Panorama Physiotherapy & Sports Injury Clinic in Surrey.
The good news is that trigger finger is very treatable, and most people improve without surgery when it’s addressed early. Let’s walk through why it happens, what to expect as it heals, and the specific tools we use to get your finger gliding smoothly again.
What Trigger Finger Actually Is
Trigger finger (the clinical name is stenosing tenosynovitis) happens when the tendon that bends your finger has trouble sliding smoothly through its protective sheath. That tendon normally glides through a series of small tunnels called pulleys, similar to a rope running through a series of guides. When the tendon or the sheath around it becomes irritated and swollen, the tendon can’t pass through the first pulley at the base of your finger without catching.
Picture a rope with a small knot in it trying to slide through a narrow ring. It can pass through, but it takes extra force, and once it’s through, it releases with a snap. That catch-and-release is exactly what you’re feeling when your finger locks and then pops straight.
Trigger finger most often affects the ring finger and thumb, though it can show up in any finger, and it’s not unusual to have it in more than one at a time.
What Causes It
Trigger finger develops when the tendon or its sheath becomes thickened and inflamed, usually from repetitive gripping or from friction that builds up over time. A few things make it more likely:
Repetitive Gripping and Hand Use
Jobs and hobbies that involve a lot of repeated gripping (think tools, sports equipment, musical instruments, or even prolonged phone and keyboard use) put repeated load through those tendons and pulleys. Over time, that friction can lead to irritation and swelling.
Underlying Health Conditions
Trigger finger shows up more often in people with diabetes, rheumatoid arthritis, or other conditions that affect connective tissue. If you have one of these conditions, it’s worth mentioning to your physiotherapist, since it can shape how we approach your treatment plan.
Age and Sex
Trigger finger is more common in adults over 40, and it affects women more often than men. We’re not entirely sure why, but hormonal factors and general tendon health likely play a role.
A Single Injury
Less commonly, a direct injury or a one-time forceful grip can irritate the tendon sheath enough to kick off the same catching pattern, even without a history of repetitive use.
Common Symptoms
Trigger finger tends to build gradually rather than appearing overnight. Watch for:
- A clicking, popping, or catching sensation when you bend or straighten the finger
- A small, tender bump at the base of the finger, right in the palm
- Stiffness that’s often worse first thing in the morning
- The finger locking in a bent position, sometimes needing gentle help from your other hand to straighten
- Pain when gripping or pressing on the base of the finger
In more advanced cases, the finger can get stuck in a bent position and won’t straighten on its own at all. That’s a sign it’s time to get it assessed rather than wait it out.
What’s the Prognosis?
Here’s the part most people want to know: will this actually get better?
For most people, yes.
Mild to moderate trigger finger responds well to conservative treatment, especially when you start addressing it early rather than pushing through the catching for months.
Mild cases (occasional catching, no locking) often improve within four to six weeks with splinting, activity modification, and a home exercise program.
Moderate cases (regular locking that needs help to release) typically take six to twelve weeks of consistent treatment, and may involve additional interventions from your physician, like a corticosteroid injection, alongside your physiotherapy program.
Persistent cases that don’t respond to several months of conservative care sometimes need a minor surgical release. Even then, physiotherapy still plays an important role afterward, restoring full mobility and strength once the tendon is moving freely again.
The takeaway: the earlier you start treatment, the better your odds of resolving this without ever needing an injection or surgery.
How We Treat Trigger Finger
Recovery comes down to giving that irritated tendon and sheath a chance to calm down, while keeping the tendon gliding so it doesn’t stiffen up in the process. Here’s what that looks like in practice.
Splinting
A small splint, usually worn at night or during aggravating activities, holds the affected finger in a slightly extended position. This keeps the tendon from repeatedly catching at the pulley while it heals, without restricting your hand for everyday tasks. Most people are surprised how much relief a well-fitted splint provides within the first couple of weeks.
Tendon Gliding Exercises
Tendon glides are the cornerstone of trigger finger exercise therapy. These are gentle, specific finger positions that move the tendon through its full range within the sheath, encouraging smooth gliding and reducing adhesions. A typical sequence includes:
- Straight hand position: Fingers fully extended, like a flat hand.
- Hook fist: Bending only at the middle and end knuckles, keeping the base knuckles straight.
- Full fist: Curling all the way into a complete fist.
- Straight fist: Bending at the base knuckles while keeping the other two joints straight.
Moving slowly and deliberately through each position, holding for a few seconds, helps the tendon travel through the pulley system without triggering that catch.
Putty Exercises
Gentle resistance exercises using therapy putty help rebuild grip strength and coordination once the acute irritation has settled. These are introduced gradually, since too much gripping too soon can flare symptoms back up.
Soft Tissue Work and Laser Therapy
Manual therapy around the base of the finger and palm helps manage swelling and improve tissue mobility. Laser therapy is another tool we sometimes use to help reduce inflammation and support tendon healing, particularly in cases that are slow to settle.
Activity Modification
We’ll also look at what’s driving the irritation in the first place. If it’s a specific grip pattern at work or in a hobby, small adjustments (a different tool grip, more frequent breaks, an ergonomic tweak) can take a lot of pressure off the healing tendon and help prevent it from coming back.
When to See a Physiotherapist
If your finger has been catching for more than a week or two, or if it’s starting to lock and you need help straightening it, it’s worth getting assessed. Trigger finger tends to respond best when it’s caught early, before the sheath becomes significantly thickened.
At Panorama Physiotherapy & Sports Injury Clinic, we’ll assess your hand, confirm what’s going on, and build a plan that fits your symptoms and your daily demands, whether that’s getting you back to work tools, the gym, or just being able to make a fist without wincing.
