Which test corresponds to elbow flexed at 90°, forearm supinated, with the patient lifting up against resistance, producing pain if positive?

• A. Cozen's test
• B. TFCC press test
• C. Mill's test
• D. Tinel's sign

Answer: (B)

The test targets the triangular fibrocartilage complex (TFCC) and how it responds to axial load across the ulnocarpal joint. When the elbow is flexed to 90 degrees and the forearm is supinated, the patient pushes up against resistance, loading the distal ulna against the carpal bones. If the TFCC is torn or degenerative, this load reproduces pain on the ulna side of the wrist, giving a positive result. This helps differentiate TFCC pathology from lateral epicondylitis (which would show pain with resisted wrist movements at the lateral elbow) or nerve symptoms (as in Tinel’s sign). In practice, a positive TFCC press test points toward TFCC injury and may prompt further imaging or referral.
