What is a potential outcome for patients with injuries at the level between C6 and C7?

Patients with injuries between the C6 and C7 vertebrae typically experience weakness in wrist and hand movement. This is due to the specific neural pathways that are affected in that region of the spinal cord. The C6 level primarily provides motor innervation to the wrist extensors, while the C7 level innervates the triceps and some hand muscles, allowing for some degree of movement and function. However, the remaining hand and finger movements may be compromised, resulting in weakness rather than complete paralysis or normal function.

This injury level may allow for some wrist extension and gross finger movements, but finer movements, such as grasp and pinch, would be significantly impaired. The ability to perform activities of daily living would be altered, requiring the use of adaptive equipment and compensatory strategies. As such, individuals with this level of injury often rely on assistance for tasks requiring precise hand function.

In contrast, injuries at this level do not lead to full mobility of all four limbs, nor do they cause complete paralysis of the legs, as those functions are primarily controlled by lower segments of the spinal cord. Normal hand function would be too optimistic given the extent of the injury's impact on motor control.
