What should you know about a growth plate fracture of the wrist?

Growth plates are softer areas near the ends of children’s and teenagers’ bones where length develops. A fall onto the hand can injure the plate near the wrist, sometimes with a crack extending into nearby bone. Pain, swelling, tenderness and reduced wrist movement are common, but an examination and imaging are needed to define the injury. Some growth plate injuries are subtle on an early X-ray, so ongoing tenderness deserves follow-up.

Keep the wrist supported and avoid sports, lifting and repeated gripping until assessed. Rest it in a comfortable position, use a wrapped cold pack for short periods, and keep the hand raised when practical. Do not try to straighten the wrist. A clinician may use a cast or splint; displaced or unstable injuries may need specialist treatment. Read about Fracture Casting and Fracture Fixation Surgery for context.

Seek urgent help if fingers become blue, pale, cold, numb or increasingly difficult to move, or if pain and swelling rapidly worsen. An obvious deformity, an open wound, or severe pain after a significant fall also needs prompt evaluation. Return for review if tenderness persists after initial reassurance, because the growth plate may require repeat assessment.

Ask which growth plate is involved, whether the alignment is satisfactory, how long support is expected, and when movement or sport can restart. Ask how follow-up will check growth and what symptoms should trigger an earlier visit.
