Pain on the little-finger side of your wrist can come from an injured ligament or cartilage structure, an irritated tendon, or increased pressure between the wrist bones. Clinicians call this ulnar-sided wrist pain. The location helps narrow the possibilities, but it does not identify the cause by itself. The Hand Society explains the possible causes of ulnar-sided wrist pain.
You might notice the pain when turning a key, opening a jar or pushing yourself out of a chair. A TFCC injury is one possible explanation, particularly if twisting or putting weight through the hand hurts. Clicking, catching or a feeling of instability can occur too. iiS Health’s TFCC information describes these symptoms.
The most useful next step is to establish which structure is painful and whether the wrist is stable.
Several conditions can produce similar symptoms. How the pain started, its precise location and any accompanying swelling, snapping or numbness help distinguish them.
The triangular fibrocartilage complex, usually shortened to TFCC, is a group of cartilage and supporting tissues between the forearm and wrist bones. It cushions the little-finger side of the wrist and helps keep the joints stable.
The TFCC can tear after a fall, a forceful twist or a fracture near the wrist. Changes can also develop gradually with age. Some tears cause pain, weakness or restricted movement, while others cause no symptoms. The Hand Society: TFCC tears.
The extensor carpi ulnaris, or ECU, is a tendon running along the back of the wrist towards the little-finger side. It helps control wrist position.
ECU tendonitis can cause tenderness, swelling and pain with gripping or rotation. It may follow increased lifting, manual work, tennis or golf. Occasionally, the tendon moves out of its usual position and produces a snapping sensation. Tendon irritation and tendon instability require different consideration during assessment. Read about ECU tendonitis at iiS Health.
Ulnar impaction syndrome develops when the ulna, the forearm bone on the little-finger side, places excessive pressure on neighbouring wrist structures. This can irritate or damage the TFCC and joint cartilage.
The problem can relate to the natural proportions of the forearm bones or changes after an injury. Gripping, twisting and bearing weight through the hand may hurt, so the symptoms can resemble a TFCC tear. iiS Health’s guide to ulnar impaction syndrome explains this relationship.
A fracture involving the little-finger side of the wrist can cause pain after a fall or forceful injury. Arthritis can produce aching, swelling and stiffness. Nerve compression and, occasionally, a lump such as a ganglion can also cause symptoms in this area. These possibilities are another reason to avoid diagnosing a TFCC tear from pain location alone. The Hand Society: ulnar wrist pain.
Twisting and lifting place demands on the structures that support the little-finger side of the wrist. Turning the forearm, gripping an object and controlling wrist position require several tissues to work together. Injury or irritation can make those ordinary movements painful. The Hand Society’s explanation of wrist mechanics describes these functions.
Before an appointment, note which everyday movement brings on the pain. For example:
These observations give your clinician a clearer starting point. You do not need to repeatedly reproduce the pain to demonstrate it.
Contact NHS 111 for urgent advice if you have severe pain, cannot move the wrist or hold objects, notice a change in shape or colour, lose feeling in the hand, or feel unwell or shivery with the pain. A snap or grinding noise during an injury also needs urgent advice.
Arrange an assessment if pain disrupts daily activities, worsens, keeps returning or has not improved after two weeks of home care. Do not wait two weeks if you suspect a fracture. NHS guidance on wrist pain.
Diagnosis starts with your history and a wrist examination. A clinician checks tenderness, movement and stability, then decides whether imaging would answer a specific question. The Hand Society describes what to expect during assessment.
Different investigations show different things:
A TFCC tear reported on an MRI does not automatically explain the pain or mean surgery is needed. Tears also appear in people whose wrists are comfortable and function normally. The scan needs to fit the symptoms and examination findings. The Hand Society: interpreting TFCC findings.
For mild symptoms without concerning injury features, reduce heavy lifting and tight gripping. A wrapped cold pack for up to 20 minutes may help. Ask a pharmacist about suitable pain relief or a wrist support. Gentle movement can help mild stiffness, but follow any immobilisation instructions already given for an injury. NHS wrist-pain self-care advice.
Adjusting a task can be more practical than stopping every activity. Consider dividing a heavy load, getting help with stubborn lids or temporarily changing a repetitive lifting task. Activity modification, bracing and hand therapy are common non-surgical approaches, chosen according to the diagnosis. The Hand Society: treatment options.
Once the injury has been assessed, a hand therapist may prescribe a splint and exercises to improve wrist stability. A generic strengthening routine may not suit the stage or type of injury.
Many causes can be managed without surgery. An operation may be considered when appropriate non-surgical treatment has not helped or when an injury needs stabilising.
For a symptomatic TFCC tear, wrist arthroscopy allows a surgeon to examine the joint through small incisions. Depending on the tear, damaged tissue may be trimmed or repaired. Risks include infection, stiffness, nerve irritation, persistent pain and continuing instability. iiS Health: TFCC treatment and surgical risks.
If ulnar impaction is driving the problem, treatment may need to reduce pressure across the joint. Selected patients may be offered an operation to shorten the ulna. This introduces additional considerations, including bone healing, so the procedure and recovery need an individual discussion. iiS Health: ulnar impaction treatment.
Ask what the proposed operation is intended to correct, what improvement is realistic and what restrictions recovery will involve.
Recovery depends on the diagnosis, the stability of the wrist and the treatment required. TFCC injuries can take considerably longer to settle than a minor strain.
For stable traumatic TFCC injuries, Gloucestershire Hospitals describes healing over roughly three months, with normal function often taking six to twelve months to return. These are estimates for that injury group, not a timetable for every painful wrist. An unstable injury may require a different approach, including surgery.
Discuss recovery in terms of your actual needs: typing, lifting at work, caring for a child or returning to sport.
If wrist pain keeps interfering with lifting, twisting or everyday tasks, iiS Health offers specialist hand and wrist assessment at The Cheshire Hand Clinic in Warrington. Care includes non-surgical and surgical options, with on-site X-ray, ultrasound and hand therapy where appropriate. Explore iiS Health’s services.
Contact iiS Health to arrange a consultation and discuss what may be causing your symptoms.
Yes. TFCC changes can develop gradually through wear, without a memorable injury. However, age-related changes do not always cause pain. A clinician needs to establish whether the TFCC is responsible for your symptoms or whether another nearby structure is involved. Gloucestershire Hospitals: degenerative TFCC changes.
No. Clicking alone cannot identify a TFCC tear. A tendon moving out of position can also produce a click or snap. Pain, reduced movement, weakness or a feeling that the wrist gives way make the sound more useful to discuss during assessment. The Hand Society: causes of wrist clicking.
No. X-rays help assess the bones and their alignment, but they do not directly show a TFCC tear. Depending on the examination and symptoms, MRI or, in selected cases, wrist arthroscopy may be considered. Further testing should help clarify the diagnosis or treatment plan. iiS Health: diagnosing TFCC injuries.
Yes, particularly when the wrist remains stable. Treatment may include protection in a splint or cast while symptoms settle and healing progresses. An unstable injury needs specific assessment because healing in an abnormal position can leave continuing problems. Stability matters alongside the presence of a tear.
The appropriate support depends on the structure involved and the movements that need protecting. A hand therapist or clinician can advise on fit, wearing time and when to begin exercises. For a diagnosed injury, splinting should form part of a rehabilitation plan with guidance on returning to activity.
You may need to reduce or pause movements that provoke symptoms. For ECU tendon problems, rehabilitation usually involves a gradual return to movement and strength, with heavy or repetitive use restricted early on. Ask for advice based on your diagnosis before returning to the activity that triggered the pain. iiS Health: ECU tendon recovery.
