ANATOMY AT A GLANCE
The ulna, carpal bones and TFCC lie on the little-finger side. Increased pressure in this area can cause symptoms.
Typical symptoms
Pain on the little-finger side may worsen when rotating the forearm or leaning on the hand. Grinding or catching can occur.
How is the cause assessed?
Examination and often imaging are needed. TFCC injuries and other conditions on this side of the wrist can cause similar pain.
Consider other causes
TFCC injuries, tendon problems and joint changes can produce similar pain. The TFCC is a ligament and fibrocartilage complex that helps stabilise this side of the wrist.
Treatment options
Without surgery
Activity adjustment and a suitable wrist support may ease symptoms. A clinician should assess the cause.
Surgical options
Surgery such as ulnar shortening is considered only after diagnosis and for persistent significant symptoms.
Suitable treatment depends on the confirmed diagnosis, examination findings and your individual needs.
When to seek an examination
Persistent pain during rotation or weight bearing and painful catching warrant specialist assessment. After injury, fractures and ligament damage also need consideration.
