Del Porto had wrist surgery in 2009. In 2012 his wrist was injured and he consulted Dr Berger for a diagnosis. Did he have the newly discovered Split UT Ligament Injury? He did not have that injury. He was cleared to play in Davis Cup but later pulled out.


You have an undiagnosed injury and it sounds as if the new forehand technique that you are performing in the clinic might be the cause. ??

If you know what a proper forehand stroke looks like you might be able to see obvious stroke technique flaws with high speed video or even with 30 or 60 fps video. This is the most important use of high speed video. See serve example below.

I'm not sure that it was my serving technique that was causing my wrist pain, but, in any case, I don't want that wrist angle in my serve. I was also practicing the 'current' forehand with a new ball machine. The forehand could also have caused the stress and pain. I stopped practicing both forehands and serves and the mild wrist pain gradually went away. This spring I'll start again with more angle between my forearm and racket on the serve and more attention to my forehand technique.

If you have quit your clinic twice already it sounds as if you have a more serious injury than I had so you should not stress it by playing. Best to see a Dr also.

Some replies with information on wrist injuries-

See especially.

Yesterday, I came across these very interesting videos from a Mayo Clinic hand surgeon, Dr Berger.
Split UT ligament - Astonishing, candid video!

He is saying that he discovered that a ligament on the ulna side of the wrist can have a split that runs along it. If I understand the first video, in the past when he looked at it arthroscopically he would see blood vessels and thought that they were defects on the outside of the ligament. He would then clean up the blood vessels as diseased tissue. But actually the ligament had a split that had opened up and he was looking inside the ligament. He found a very easy test of pressing on the side of the wrist to diagnose this specific injury that does not show on MRIs.

I hope that you can understand the videos and ask your Dr his thoughts. The Mayo Clinic Dr sounds as if this was a recent discovery.

Wrist stress by questionable serving technique from another thread -
Example of technique flaw picked up with high speed video.

REALITY: If your technique is not effective for a strong serve you will be learning the wrong muscle memory and technique. However, you will probably hit the ball more reproducibly and that may allow you to improve your serve's reliability and pace up to a point. First, learn an effective technique without any biomechanical flaws that would prevent an effective serve. Or hire a well-qualified instructor that can train the proper techniques.

This is one reason that I hate to practice and avoid it. Maybe an effective practice method using high speed video would be to video just 1 - 3 strokes and immediately look at the videos and analyze them. Find flaws, they are very easy to spot. Make corrections. Repeat. Looking at videos of every 2 or 3 strokes is very, very cumbersome. Is it better to practice for an hour and then to go home and view the videos only to find that you never use leg thrust, or that your wrist has a bend in it that might cause injury.

For example, I think that this wrist angle at impact is wrong and stressful. This technique might have contributed to the slight wrist pain that I was experiencing at the time that the video was taken. Compare to pro servers wrist angles viewed from behind on other videos.

Pro server.
