I was just diagnosed with a TFCC injury by a hand specialist. He came to this conclusion after physical exam and an x-ray (although the x-ray showed nothing)The injury is on my non-dominant hand. I guess the injury was caused by overuse/technique issue rather than some acute cause like a fall (I have a two-handed backhand). I have pain when making contact with the ball during my stroke on my backhand. It's a sharp pain on ulnar side. I recently when from poly/multi to gut/poly and I think I added more wrist in my stroke to get a bit more spin to bring the ball down.There is also some discomfort with supination of the wrist or lifting something palm up. The joint is still stable according to the MD and I don't have much if any weight bearing pain. The wrist does feel a bit shaky with weight bearing. He put me in a "Bledsoe" brace that goes above the elbow and does not allow me to pronate/supinate my wrist. I have to wear it for 4 weeks. For those with ulnar sided wrist injuries, what diagnosis did you receive and does what I'm describing sound like what you experienced in terms of when you felt pain? Based on what I have read this could also be a longitudinal split-tear in the ulnotriquetral (UT) ligament, or even something with ECU but the MD wasn't super familiar with UT injury as many docs are unaware of it. Thanks for any responses.
