What should you know about a hairline fracture in the wrist?

A small fracture can involve one of the wrist bones or the end of a forearm bone. Pain, tenderness, swelling and reduced grip may follow a fall, repeated loading or another force. Some wrist injuries are difficult to see on an early plain X-ray, especially when pain is focused near the thumb side. Examination and, when needed, repeat or advanced imaging help identify the bone involved and whether the joint is stable.

Remove rings if swelling is developing. Rest the hand from lifting, pushing, gripping and impact; keep the wrist supported in the splint recommended for you. Elevation and a wrapped cold pack may ease swelling, while the fingers should move gently if that is comfortable and permitted. Keep the splint dry, check the skin and do not alter its fit without advice. Rehabilitation can restore motion and strength after the clinician confirms that loading is appropriate.

Get urgent help if fingers become blue, pale, cold, numb or increasingly difficult to move, or if swelling rapidly worsens. Prompt assessment is also needed after a significant fall, visible deformity, an open wound, or pain that remains sharply localised despite rest.

Ask which bone may be injured, how long the splint is needed, whether you may use the hand for work, when repeat imaging is appropriate, and which exercises protect wrist and finger motion without stressing the fracture.
