About TFCC tear (pinky-side wrist pain)
The triangular fibrocartilage complex, or TFCC, is a small group of cartilage and ligaments on the pinky side of the wrist. It cushions the joint between the forearm and small wrist bones and helps keep the two forearm bones stable when you turn your palm up and down.
The TFCC can tear suddenly, such as from a fall onto an outstretched hand or a forceful twist, or it can wear down gradually with age and repetitive use. Golfers, tennis players, gymnasts, and people who use hammers or power tools are commonly affected.
Some tears cause only mild, occasional pain, while others make the wrist feel weak or unstable. The treatment plan depends largely on whether the forearm joint is stable.
Common symptoms
- Aching or sharp pain on the pinky side of the wrist
- Pain with turning a doorknob, opening a jar, or using a racquet or club
- Clicking or popping with wrist rotation
- Weak grip or pain when pushing up from a chair
- A feeling that the wrist is loose or unstable
Common causes and risk factors
- A fall onto an outstretched hand
- Forceful twisting or pulling of the wrist
- Repetitive gripping and rotating in sports or work
- Age-related wear of the cartilage
- A forearm bone that is slightly longer than usual on the pinky side
How we diagnose it
Our physicians examine the wrist with tests that load and rotate the pinky side, check the stability of the forearm joint, and look for tendon problems that can mimic a TFCC tear. Diagnostic ultrasound at the exam table helps evaluate nearby tendons and ligaments and can show fluid or tearing at the outer wrist. X-rays check the length of the forearm bones and look for fractures. An MRI or MR arthrogram and a referral to a hand surgeon are recommended when the joint seems unstable or symptoms persist.
How Propel treats TFCC tear (pinky-side wrist pain)
Most TFCC injuries are first treated with a wrist brace or splint that limits rotation, along with activity changes and a hand rehabilitation program focused on grip and forearm strength and wrist control. Many people notice steady improvement over several weeks.
When pain lingers, an ultrasound-guided injection into the painful area can calm irritation, and PRP may support healing in selected degenerative or partial tears. A tear that leaves the forearm joint unstable, or one that does not respond to good nonsurgical care, is best evaluated by a hand surgeon, and we coordinate that referral.

Exam and in-office ultrasound
A hands-on exam, then ultrasound at the exam table, often while you move, so your physician can see the tendon, joint, or nerve involved.
- 3.
A clear diagnosis and plan
You leave knowing what is wrong and what your options are, from strength-based rehab to procedures, and why we recommend each one.

Treatment and follow-through
Most procedures happen here in the office. We coordinate with your physical therapist and check progress against the goals you set.
Questions about TFCC tear (pinky-side wrist pain)
- Will a TFCC tear heal on its own?
- Many do improve with bracing, rest from aggravating activities, and hand therapy. The outer part of the TFCC has better blood supply and tends to heal more reliably than the central part.
- How long should I wear a wrist brace for a TFCC tear?
- It varies, but bracing is often used for several weeks and then weaned as strength and comfort return. We tailor the timeline to your symptoms and how stable the wrist is.
- When does a TFCC tear need surgery?
- Surgery is usually considered when the forearm joint is unstable or when pain continues despite a solid course of bracing, therapy, and injection options. A hand surgeon can repair or clean up the tear.
