I apologize, not the capitate. I meant metacarpal V. I was thinking something else when i wrote that... Thanks again!
I am not sure about the hairline fracture of the knuckle adjoining the capitate (It might not be visible with the image quality). However there is a boxers fracture (fracture of the 5th metacarpal) seen. I would suggest consulting an orthopedician for appropriate management.
Hope this helps.
