Hand fracture swelling: what to know

A fracture can injure bone, muscles, ligaments, and small blood vessels, causing fluid and blood to collect around the area. Swelling may make the hand feel tight and can limit finger movement. It may increase when the hand hangs down and ease when it is supported. A distal radius fracture near the wrist can also cause swelling in the wrist, hand, and fingers. Swelling alone cannot show whether the bone has healed or whether its position is stable.

Follow the splint, cast, and movement instructions provided after assessment. Keep the hand elevated when resting if advised, and gently move free fingers to the comfortable limit unless your clinician has restricted movement. Keep a cast or dressing dry and do not insert objects underneath it. Avoid lifting, gripping, or leaning on the injured hand until you have clear guidance. Pain relief should match advice from your treating clinician.

Contact the treating service promptly if swelling is rapidly increasing, the cast feels too tight, pain is escalating, or fingers become numb, cold, pale, or blue. Seek urgent help for severe uncontrolled pain, new deformity, inability to move the fingers, or an open injury. Persistent swelling or reduced movement after the expected review period should also be checked rather than managed by changing the splint yourself.

Ask how much movement is safe, how to position the hand, when the splint or cast needs checking, and which symptoms should bring you back sooner. Tell the clinician about changes in pain, sensation, finger colour, swelling, and your ability to move the fingers.
