Minerva Cast is indicated for which region of the spine?

• A. Cervical spine only
• B. Upper dorsal and cervical spine
• C. Lower dorsal spine
• D. Lower lumbar spine

Answer: (B)

The Minerva cast is an immobilization device that fixes the skull to the upper thorax to create rigid stabilization of the craniovertebral region and the upper cervical spine. This design is used when injuries involve the craniovertebral junction and the upper cervical levels, where any movement can jeopardize the spinal cord and hinder healing. By spanning from the head to the upper dorsal (upper thoracic) spine, it effectively limits all motion—flexion, extension, and rotation—in that critical region. It would not be used for isolated lower dorsal or lumbar injuries, which require other forms of immobilization, such as thoracolumbar jackets or braces.
