Triangular Fibrocartilage Complex injuries is one of the most common wrist injuries treated by a hand therapist.
Research published by the National Library of Medicine in 2023 shows TFCC abnormalities can affect roughly 1 in 4 people under 30, which then rises up to 1 in 2 people over the age of 70.
In this essential guide, we’ll break down what causes TFCC tears, common symptoms to watch out for, treatment options and how a targeted rehabilitation program is the key to full recovery.
Quick Breakdown: What You Need to Know
- 🧠 Key Insight: TFCC (Triangular Fibrocartilage Complex) injuries are a common source of ulnar-sided wrist pain, affecting stability, grip strength, and wrist rotation.
- 🔬 What It Is: The TFCC is a load-bearing structure on the pinky side of the wrist made up of cartilage and ligaments that stabilise and cushion the joint during movement.
- ⚠️ How It Happens: Injuries can be traumatic (sudden falls, twists, sports impacts) or degenerative (gradual wear and tear from repetitive loading or age-related changes).
- 🩺 Diagnosis Matters: A hand therapist uses clinical testing, movement assessment, and strength testing to identify TFCC injuries. MRI’s and X-rays sometimes used, not always definitive.
- 💊 Treatment Approach: Most TFCC injuries improve with non-surgical management, including splinting, load management, and structured hand therapy. Surgery is reserved for more complex cases.
- 🏥 Get Help Early: Early assessment improves outcomes and helps prevent chronic wrist instability.
What is the Triangular Fibrocartilage Complex?
The triangular fibrocartilage (or TFCC ) is a highly complex load-bearing structure on the ulnar side of the wrist. Acting as a shock absorber and stabiliser for the “pinky side” of your wrist, it sits between the ulna bone and the small carpal bones and is made up of cartilage, ligaments and tendons.
These work together to connect the two forearm bones to the wrist. When the TFCC is injured, the wrist can often feel weak, tired, unstable and painful especially on the little finger side.
Understanding the TFCC Anatomy And Structure
What Causes TFCC Injuries?
Injuries of this nature can develop in many different ways, from a single traumatic event to gradual wear and tear over time. Understanding what caused your injury is an important first step. Treatment is fundamentally most effective once the reasons for the injury are understood. Broadly, Triangular Fibrocartilage Complex injuries fall into two categories: traumatic or degenerative.
Traumatic injuries (Class 1)
Traumatic TFCC injuries can occur suddenly either by accident such as slipping on a wet floor or from external sources such as a rugby tackle where the wrist is forced into rotation.
Injuries are caused by a twist of the wrist or a distal radius fracture, which frequently involves a tear.
Degenerative injuries (Class 2)
Unlike traumatic injuries, degenerative TFCC tears take time to develop. Repetitive loading of the wrist is usually a leading culprit, such as years of swinging a tennis racquet, lifting heavy loads on a worksite or long-term power tool usage
These repetitive practices slowly break down the cartilage and surrounding tissue. As we get older, this tissue gradually becomes thinner and less elastic, making it more vulnerable to tearing even without a specific incident.
Degenerative triangular fibrocartilage complex injuries are often associated with ulnocarpal abutment, where the ulna wrist bone sits higher than normal in relation to the radius wrist bone.
Degenerative injuries are harder to pinpoint than traumatic ones, as there is no single moment of injury and slowly creeps up on unsuspecting patients. Many people describe a slow build-up of ulnar-sided wrist pain that worsens with activity over months or years.
How is a TFCC Injury Accurately Diagnosed By A Hand Therapist?
What Conditions Can Be Mistaken For A TFCC Tear?
Ulnar-sided wrist pain (often known as the “low back pain of the wrist” ) is notoriously challenging to diagnose because several conditions can closely mimic a TFCC tear. This is one of the reasons why a thorough clinical assessment by a hand therapist is so important before any diagnosis is confirmed.

Ligament And Cartilage Injuries
Tears to the small ligaments connecting the wrist bones can produce ulnar-sided pain and instability.
Cartilage damage to nearby bones can cause the same localised aching feeling on the pinky side of the wrist and can look almost identical to a TFCC injury.
Bone And Joint Conditions
Several bone conditions share the same symptoms as a TFCC tear. Some of these include:
Tendon Conditions
There are two tendons that run directly along the ulnar (pinky) side of the wrist. These are known as the ECU on the back and the FCU on the palm side.
Irritation or inflammation of either tendon is one of the most common conditions mistaken for a TFCC tear, as the pain location and aggravating activities (gripping, twisting) are nearly identical. Conditions such as tennis elbow is a good example.
Other Conditions
While not as common as some of the other conditions, there are other causes of ulnar-sided wrist pain that can also mimic a TFCC injury.
What Are The Treatment Options for TFCC Injuries?
Non-surgical Treatment
When If no large or complex tears are found during initial assessment, then most ulnar-sided injuries can be treated through non-surgical means. This includes a period of custom splinting or wrist braces a wrist widget to stabilise the wrist joint as the complex heals.
Exercises that strengthen and stabilise the ulnar side of the wrist will also help the healing and allow you to return to normal activities, work, and activities of daily living.
Surgical Treatment
Surgical repair is required if the injury doesn’t heal with splinting and exercises, or in cases of joint instability and complex tears that require mechanical fixation.
Depending on the severity and location of the lesion, specific procedures may differ. Referral to a hand surgeon by a general practitioner (GP) is required to determine whether the damaged complex requires surgery.
When Should You See a Hand Therapist?
You should consider making an appointment to see a hand therapist as soon as you notice or start feeling persistent wrist pain, hear constant clicking noises or feel a large degree of weakness.
We also recommend not waiting too long; try to book an appointment with us within the first few weeks. Early assessment is key to avoiding untreated TFCC injuries from becoming a chronic issue, such as ongoing instability or the development of long-term joint problems. A hand therapist has the expertise to assess, diagnose, and treat these injuries, helping you recover safely and return to normal activities as soon as possible.
Signs You Might Have a TFCC Injury
| Signs | What It May Indicate |
|---|---|
| Ongoing pain | Pain on the pinky side of your wrist |
| Clicking or catching | Clicking, popping, or a catching feeling when moving your wrist |
| Weak grip | Loss of strength or a feeling your wrist might give way |
| Pain with pressure or twist | Hurts when pushing, lifting, or twisting objects |
| Recent injury | Pain or swelling after a fall or forceful wrist twist |
Hand Therapy Treatment Steps
Hand therapy is important in non-surgical and surgical management of TFCC injuries. Below is a step-by-step process on how injuries are managed at Hand Therapy Experts:
- Assessment: History taking and physical examination. We will review any relevant scans and reports or refer you for further imaging scans.
- Treatment: Depending on the severity of your injury, you may require a wrist splint or brace. Exercises will also be given to strengthen muscles that stabilise the Triangular Fibrocartilage Complex.
- Return to sport and work plan: guidance will be provided through a structured return-to-work rehabilitation program and sport progression plan.
- Follow-up: follow-up appointments to assess your progress and update exercises as your injury heals. If your injury is not improving after a few sessions, we may recommend that you see a specialist hand surgeon for an opinion on ongoing management.
- Recovery: As your TFCC injury fully recovers, you won’t be required to continuously wear splints or perform regular exercises. You will be able to return to sport and work without restrictions once the injury is fully healed.
Activities to Avoid When You Have A TFCC Injury
When you have a TFCC injury, certain activities and exercises can worsen your condition, especially if it hasn’t fully healed yet. Here are some common activities to avoid:
- Heavy gripping and lifting: Objects and tools that need force applied can cause further damage and delay your recovery. This can include tools like hammers or screwdrivers. Also, everyday actions like turning keys or door handles can also aggravate your injury if done so often.
- Forearm rotation: Repetitive twisting of the forearm, such as when opening jars or doors, is one of the most common ways ulnar-sided tears can be majorly aggravated. We recommend avoiding activities like this until your symptoms are better.
- High-impact sport: Swinging actions in racket sports like tennis and badminton and golf or baseball all place a large amount of rotational force through the wrist. These should be avoided until the injury has been fully rehabilitated.
- Weight-bearing wrist exercises: push-ups put extreme strain on the wrist in extension, which places more load on the structure. Pull-ups and hand planks should also be avoided. An elbow plank is a useful alternative. As you commence wrist exercises during your rehabilitation program, fist push-ups can help reduce wrist extension strain.
