Growth plate fracture in children

Growth plates are areas of developing tissue near the ends of many bones. They help bones lengthen as a child grows and are more vulnerable to injury than mature bone. A fall, collision, twist, or direct blow can cause a fracture there. Pain, swelling, bruising, tenderness, or reduced use of an arm or leg may follow. The injury can occur at the wrist, elbow, ankle, knee, or another growing bone, and the outside appearance may not show its full extent.

Stop the activity, keep the injured area supported, and use a wrapped cold pack to ease swelling. Do not straighten a visibly changed limb or ask the child to keep testing it. Remove tight jewellery near an injured hand or foot. Arrange assessment after a significant injury, especially when the child cannot bear weight or use the limb normally. Clinicians use an examination and imaging to guide protection, follow-up, and any needed treatment.

Seek urgent care for an open wound, an unusual bend, severe or worsening pain, rapidly increasing swelling, or a limb or digit that is pale, blue, cold, numb, or difficult to move. A child who cannot walk, grip, or use the injured limb should be assessed promptly. After treatment, keep review appointments even if pain settles, because changes in alignment or growth may need monitoring. Report a new limp, crooked appearance, reduced movement, or ongoing pain.

Ask which bone is involved, whether the growth plate or joint surface is affected, what protection is needed, how follow-up will check healing, and which activities are safe during recovery.
