When to worry about visible deformity after an elbow injury

An elbow dislocation changes the normal alignment of the upper arm and forearm bones. The joint may look bent, uneven, or visibly displaced, with swelling and marked pain. A fracture can occur at the same time, so appearance alone cannot show how much damage has occurred. Nerve or blood-vessel irritation may cause tingling, loss of feeling, unusual hand colour, or reduced temperature in the fingers.

Keep the arm still in the position you found it and support it with a sling or folded cloth if this does not force the joint to move. Remove rings, watches, and bracelets before swelling increases. Do not try to straighten the elbow or put it back into place. Arrange urgent evaluation and avoid food or drink if emergency treatment may be needed, unless a clinician advises otherwise.

Call emergency services or go to an emergency department for an obvious deformity, severe or increasing pain, rapidly worsening swelling, an open wound, heavy bleeding, or inability to move the fingers. Treat numbness, pins and needles, a cold hand, pale or bluish fingers, or a weak pulse as urgent warning signs because circulation or nerves may be affected. Even if the elbow seems to slip back into place, prompt assessment is still needed.

Ask whether imaging is needed to check for a fracture, whether the nerves and circulation in your hand are intact, and how long the joint should be protected. Clarify when gentle movement can begin, which activities to avoid, and which symptoms should bring you back sooner.
