Distal Radioulnar Joint Subluxation

A video of the wrist of a martial arts exponent who had a fall on his right hand 2 years ago during competition. He sustained an injury to his wrist causing him to have pain during punching. He also had painful full flexion of his wrist and resisted extension.

I have demonstrated the dorsal movement of the ulna with a fixed radius in the video. Although he would maintain some form of wrist stability with taping, he should be seen by a Hand surgeon to correct the instability.

Finger (Thumb) Dislocation

Here's a video of a female martial arts exponent who dislocated her left thumb 2 years ago after receiving a kick during competition. I did a test to evaluate the hypermobility of her joint. She is also having some hypermobility of her right thumb but it was less mobile.
