Ulnar and Tibial Nerves- Neuromonitoring?

Ulnar Nerve:
Ulnar nerve is important to monitor during Peripheral Neuropathy, ulnar nerve palsy (if a single ulnar nerve involved, it is called mononeuropathy?)

Ulnar nerves for upper and Tibial Nerves for lower sensory evoked potentials (SSEPs) are the most commonly used nerves, normally pad electrodes are placed for stimulation and the resulting sensory activities are recorded at the scalp sites using needle electrodes.

Ulnar nerve damage due to fractures or other causes can affect the movement and sensation in the hands and palm, the image (ADAM) shows the ulnar nerve damage due to fracture, the image also shows the trajectory of ulnar nerve. It originates from the brachial plexus and travels down the arm. Any compression of brachial plexus due to prolonged pressue on elbow or fracture of elbow could cause ulnar nerve damage. Ulnar nerve is most commonly used to monitor upper extremities during cervical spinal surgeries.

Tibial Nerve:
