What type of cast is applied for a fracture of the cervical or upper thoracic vertebrae?

1. Short arm cast

2. Long leg cast

3. Minerva jacket

4. Half body cast

The correct answer is: Minerva jacket

A Minerva jacket is a specialized orthotic device designed to provide immobilization and support for the cervical and upper thoracic spine. This type of cast is crucial for treating fractures in this area because it effectively restricts movement, which is vital for the healing process and for maintaining spinal stability. The design of the Minerva jacket envelops the upper body and extends from the chin down to the thorax, offering a comprehensive approach to immobilization. This limits mobility in the cervical and upper thoracic regions, minimizing the risk of further injury and promoting healing. In contrast, other types of casts, such as the short arm cast, long leg cast, and half body cast, are not suited for immobilizing the cervical or upper thoracic regions. They are designed for different parts of the body or types of injuries, thus making them ineffective for addressing fractures in this specific area of the spine. The Minerva jacket is, therefore, the appropriate choice for ensuring both immobilization and protection during recovery from cervical or upper thoracic vertebral fractures.
