What type of cast will be applied after performing an open reduction internal fixation of a tibia?

After performing an open reduction internal fixation (ORIF) of a tibia, a cylindrical cast is typically applied to provide the necessary immobilization and support during the healing process. The cylindrical design ensures that the entire limb, including the ankle and foot, is encompassed within the cast, allowing for a stable environment that prevents movement at the fracture site.

Using a cylindrical cast is beneficial because it offers uniform support and protection, which are crucial following surgical intervention. Additionally, the circular shape of the cast helps in redistributing pressure evenly around the limb, reducing the risk of complications such as pressure sores or circulation issues.

In contrast, a short leg cast generally only encompasses the lower leg and does not provide the same level of immobilization for the knee or the ankle, which may be necessary after an ORIF procedure. A walking boot offers some support but is typically used in less acute situations or after some initial healing has occurred. A splint is often used for initial immobilization or when a fracture is not as stable, but it would not provide the rigid support necessary after a surgical fixation. Thus, the cylindrical cast is the most appropriate choice for post-surgical immobilization of the tibia following ORIF.
