oAlways x-ray.

oThis effusion generally needs aspiration to relieve pain and allow better examination. Ask for senior help.

oThese patients will need fracture clinic follow up

Post-traumatic effusion that develops more slowly (6 hours or more) is due to reactive effusion.

oAlways x-ray.

oLarge effusions of this kind may need aspiration for the same reason. Seek senior help.

Smaller and less severe effusions can be treated with single tubigrip support, non weight bearing crutches, analgesia, and exercise sheet. They should be followed in the A&E review clinic in a week time
