Supination Lift Test

TFCC injuries are commonly caused by traumatic events such as falling on an outstretched hand or repetitive loading from activities involving rotation or ulnar deviation. They may also result from degenerative changes, particularly in patients with positive ulnar variance or age-related cartilage wear.

Diagnosis typically involves a clinical examination using tests like the Supination Lift Test or TFCC compression test, followed by imaging such as MRI or wrist arthroscopy to confirm the tear and evaluate severity.

Minor or stable TFCC tears can heal with conservative management, including immobilization and physical therapy, while larger or unstable tears often require surgical intervention. Proper diagnosis and load management are critical to avoid chronic dysfunction.
