Trigger finger surgery frees a tendon that catches, clicks or locks as you bend and straighten a finger or thumb, a common and often painful condition known medically as stenosing tenosynovitis. At our Harley Street practice in London, Ms Anna De Leo, a GMC-registered Consultant Plastic, Reconstructive and Aesthetic Surgeon who holds the European Diploma in Hand Surgery and advanced qualifications in microsurgery, offers a clear, stepwise approach to treatment.
Not every trigger finger needs an operation. Many settle with rest, a splint or a precisely placed steroid injection, and these options are discussed first. When triggering keeps returning, when the finger locks in the palm, or when stiffness begins to set in, a trigger finger release is a short, reliable procedure. It is normally performed under local anaesthetic in around ten to fifteen minutes, and most patients move the finger freely straight away.
01What Is Trigger Finger and When Is Trigger Finger Surgery Needed?
The tendons that bend your fingers run along the palm side of each digit inside a smooth, tunnel-like sheath. At intervals, this sheath is reinforced by fibrous bands called pulleys, which hold the tendon close to the bone so that the finger bends efficiently. The first of these, the A1 pulley, sits at the base of the finger, roughly in line with the crease where the finger meets the palm.
In trigger finger, the tendon and its sheath become inflamed and thickened, and a small nodule may form on the tendon. The nodule then has to squeeze through the tight A1 pulley each time the finger moves. The result is a painful catch or click, a finger that sticks in a bent position and suddenly snaps straight, or, in more advanced cases, a finger that locks and has to be straightened with the other hand.
Typical symptoms include:
- Pain and a tender lump at the base of the finger or thumb.
- Clicking, catching or locking, often worst in the morning.
- Stiffness and difficulty making a full fist.
- Over time, a finger that will no longer fully straighten.
Trigger finger is more common in women, in people over 40, and in those with diabetes, rheumatoid arthritis, thyroid disease or carpal tunnel syndrome. Repetitive gripping at work, in the garden or in sport, and unaccustomed heavy use of the hand, can also contribute. The thumb, ring and middle fingers are most often affected, and several digits can be involved at once.
02Diagnosis and Non-Surgical Treatment
Trigger finger is usually diagnosed by examination alone. Ms Anna De Leo will feel for the tender nodule, watch the finger move, assess any fixed bend at the middle joint, and check for related conditions such as carpal tunnel syndrome or Dupuytren’s disease, which can look similar. An ultrasound scan is occasionally helpful when the picture is less typical.
Treatment follows a graduated path, beginning with the least invasive options:
- Rest and activity modification, reducing the gripping tasks that provoke inflammation.
- Splinting, often at night, to keep the finger straight and allow the tendon to settle.
- Hand therapy with gentle tendon-gliding exercises.
- A corticosteroid injection into the tendon sheath, which resolves symptoms for a good proportion of patients, sometimes permanently. Injections tend to be less effective in people with diabetes or long-standing triggering, and a second injection may be considered.
Trigger finger surgery is advised when symptoms persist or return after injection, when the finger locks, or when a fixed bend is starting to develop. Acting before the middle joint becomes permanently stiff gives the best functional result.
03Your Consultation on Harley Street
Consultations take place at 64 Harley Street in Marylebone, in one of the most established medical quarters in the world; from fewer than a dozen doctors in the 1840s, Harley Street had almost 200 by 1914, and today more than 3,000 people work in the area. You will be seen by Ms De Leo herself, with time to describe how the triggering affects your work, sleep and daily life.
She will examine the hand, explain the findings in plain language, and set out the options in order: what can be tried without surgery, what an injection is likely to achieve, and when trigger finger surgery becomes the better choice. If an injection is appropriate, it can often be given at the same visit.
Questions about trigger finger surgery cost factors are answered openly. Your personalised plan depends on how many fingers are affected, whether scans are needed, the setting for the procedure and any hand therapy afterwards. For anyone looking for a trigger finger specialist near Marylebone or elsewhere in central London, the practice is open every day by appointment.
04How Trigger Finger Surgery Is Performed
The operation, known as an A1 pulley release, is usually carried out under a wide-awake local anaesthetic. You remain fully alert, no fasting is needed, and you can go home shortly afterwards.
- A fine local anaesthetic injection numbs the base of the affected finger or thumb.
- A short incision of around one to two centimetres is made in the palm, in or close to a natural skin crease.
- Working under magnification, the tight A1 pulley is divided, carefully protecting the digital nerves and arteries that run on either side of the tendon. In the thumb, these nerves lie particularly close to the surface, so precision matters.
- Because you are awake, you are asked to bend and straighten the finger, confirming that the tendon now glides freely.
- The skin is closed with fine sutures and a light dressing applied.
Ms De Leo’s microsurgical training underpins this careful technique. In selected patients, a percutaneous release using a needle, without an open incision, may be discussed, although open release allows the structures to be seen directly and is favoured in most cases, particularly for the thumb and little finger. Several fingers can be released at the same sitting if needed.
Children can also develop a trigger thumb, which behaves differently from the adult condition; paediatric cases are assessed individually and may be observed before any treatment is advised.
A finger that locks is more than an irritation; treated early and precisely, it usually becomes a finger you simply stop thinking about.

05Trigger Finger Surgery Recovery Time
One of the advantages of trigger finger surgery is how quickly normal movement returns. You are encouraged to move the finger fully from the first day, which helps prevent stiffness and keeps the tendon gliding.
- First few days: keep the hand elevated, the dressing dry, and use the hand for light tasks such as typing and eating.
- Within one week: most people return to desk work; driving is usually possible once you can grip the wheel comfortably.
- At 10–14 days: the wound is checked and sutures are removed.
- Weeks 2–6: tenderness in the palm gradually fades; scar massage helps the scar soften.
- Weeks 4–8: heavier gripping, manual work and sport are resumed progressively.
If the middle joint had become bent before surgery, a programme of hand therapy and splinting may be needed to regain full straightening. Follow-up after trigger finger surgery takes place at our Harley Street clinic in London, and the ADLSynergy recovery team can support scar care and comfortable healing.
06Trigger Finger Surgery Risks and Results
Trigger finger surgery is one of the most successful operations in hand surgery, with the large majority of patients free of triggering afterwards. Nonetheless, all surgery carries risks, and results vary between individuals. Possible complications include:
- Wound infection, bleeding or a tender scar.
- Temporary swelling and stiffness of the finger.
- Injury to a digital nerve, causing numbness on one side of the finger, which is uncommon.
- Persistent or recurrent triggering, which is rare after a complete release.
- Bowstringing of the tendon, a rare problem if adjacent pulleys are damaged.
- Ongoing loss of straightening where a fixed contracture was already present.
- Complex regional pain syndrome, which is uncommon.
Searching for trigger finger “before and after” results, patients mostly want to know that the click will go and the finger will move freely; for most, it does, and an honest assessment of your own situation is part of every consultation.
