A wrist sprain is an injury to the ligaments that support the wrist, most often after a fall onto an outstretched hand. Sprains range from mild stretching to a complete ligament tear, and an apparently minor injury can sometimes hide a fracture.
A wrist sprain occurs when the ligaments that stabilise the wrist stretch beyond their limits or tear. Most happen after a fall onto an outstretched hand, and they range from mild (a stretched ligament) to severe (a complete tear or the ligament pulling off the bone). Many mild sprains recover fully with simple care, but an injury that seems minor can hide a torn ligament or a fracture.
Assessment focuses on how the injury happened, where the tenderness is, and how the wrist moves. A particular priority is excluding a fracture — especially a scaphoid fracture on the thumb side of the wrist, which can be present even when the first X-ray looks normal. For that reason a suspected scaphoid injury is typically splinted and re-imaged after a short interval rather than dismissed as a sprain.
First-line care for mild and moderate sprains is rest, ice, compression and elevation, simple analgesia, and — where needed — a splint followed by hand therapy to restore movement and strength. Suspected complete ligament tears warrant timely referral to a hand or orthopaedic surgeon, as outcomes for severe injuries depend partly on how quickly they are treated. Prompt, accurate diagnosis helps avoid longer-term problems such as chronic pain, stiffness and arthritis.
