Physical examination of a spinal cord injury may reveal which of the following?

A physical examination of a spinal cord injury typically presents several hallmark findings, with midline bony tenderness being a significant indicator. This tenderness suggests potential involvement of the vertebral structure surrounding the spinal cord, which is crucial for assessing the extent of injury. It indicates that there could be damage to the bony anatomy, such as fractures or dislocations in the spine that may compromise spinal cord integrity.

Midline bony tenderness points directly to a structural issue in the vertebrae, which is essential to identify, as it can help guide further imaging studies, such as X-rays or MRI, to assess for major injuries that could lead to neurological deficits or long-term complications.

While focal weakness can be present depending on the level and severity of the injury, it is not always observable during a physical examination, especially in acute settings. Skin discoloration may also occur due to various reasons, such as local hematoma or bruising, but it is less specific to spinal cord injuries. Increased heart rate can occur due to autonomic dysregulation after a spinal cord injury, particularly in cases of cervical injuries, but it is not a physical examination finding specific to the injury itself.

Therefore, midline bony tenderness is the most indicative finding in
