Computed tomography in the evaluation of partial growth plate arrest in children.

The radiologic evaluation of growth plate injuries is vital to the surgical management of children with partial growth plate arrests. Plain film radiographs are of limited value, and in some cases, even high quality tomography does not provide adequate detail. Computed tomography (CT) can however provide a cross-sectional display and may also aid in defining the relative position of bone and cartilage in the affected area. This may prove invaluable to the surgeon in the planning of his operation. The vast majority of cases of partial growth arrest can be adequately examined by conventional means, but CT can provide additional information in cases where plain film examination is inadequate.
