      Hi Steve,

      I scanned this teenager who hyperextended his thumb during footy. Very tender dorsal aspect of MCPJ. When I was flexing his thumb, it looked like the joint was slightly widened compared to the right side. Also thought there was echogenic fluid within the joint, would this be blood? I was thinking back to your lectures where blood often means fracture? Could you get blood in the joint without having a fracture?

      I thought the collateral ligaments were NAD. Pt stated XR done a week prior elsewhere NAD.

      Thanks!

      Hi Diane,

      That looks exactly like a haemarthrosis.

      The capsular ligaments also look a bit hypo echoic and thick.

      You don’t need a fracture to get a haemarthrosis as any intra-articular injury can bleed into the joint.

      I always consider a fracture when I see a haemarthrosis, but it is not always present.

      The fact there is a haemarthrosis may indicate cross sectional imaging if the symptoms don’t resolve.

      Steve.

      Would there be any significance for the slightly widened joint compared to the asymptomatic left side or is this due to the extra blood in there?

      Thanks!

      think the capsule ligaments looked a bit thick and hypo echoic,

      I think the capsule has been injured without a complete disruption.

      The injured capsule will account for the joint laxity / hyper-mobility.

      Steve.

      Does this laxity get better with time or does it remain like that?

      Thanks!
