Neck pain and cervical radiculopathy most frequently occur at C6-C7. Cervical pain, cervical disc herniation, and cervical radiculopathy are most commonly seen at C6-C7, but they can also occur at C5-C6. The patient will complain of neck pain due to nerve root irritation, with the pain radiating to the ipsilateral upper extremity. The patient may also complain of numbness, paresthesia, and weakness. Coughing, sneezing, and neck movements make the pain worse.

A careful examination of the patient is important. Each nerve involved will show its effect on motor power, sensation, and reflexes. For example, a C3-C4 disc bulge will affect the C4 nerve root, leading to some sensory deficit around the shoulder, as seen in the diagram of the area supplied by C4. It could also affect the respiratory system.

If you have a C4-C5 disc bulge affecting the C5 nerve root, this will affect sensation around the shoulder area. Additionally, C5 will affect the biceps reflex because the biceps reflex is primarily controlled by C5. Regarding motor function, C5 will affect the deltoid's power and strength and influence elbow flexion, which involves C5 and C6.

A C5-C6 disc bulge or herniation will affect the C6 nerve root, impacting sensation at the index finger and thumb, as shown in the diagram. How about the reflexes? The C6 reflex is the brachioradialis reflex. As for motor function, C6 controls wrist extension (extensor carpi radialis longus and brevis) and contributes to elbow flexion, which involves both C5 and C6.

A C6-C7 disc bulge or herniation will affect the C7 nerve root. C7 typically affects sensation in the middle finger. Motor-wise, C7 is responsible for elbow extension (triceps), wrist flexion, and finger extension. The reflex associated with C7 is the triceps reflex, while C6 controls the brachioradialis reflex, and C5 controls the biceps reflex.

A disc bulge between C7 and T1 will affect the C8 nerve root. The area affected will be the medial two fingers and the medial part of the forearm, as shown in the diagram. Motor-wise, C8 is responsible for finger flexion. There is no reflex test available for C8.

How about a disc bulge between T1 and T2? This will affect the T1 nerve root. The affected area of sensation is shown in the diagram. Motor-wise, the T1 nerve root controls the interossei muscles, which are responsible for finger abduction and adduction (spreading the fingers apart and bringing them together).
