Brief Answer:
C4 disc herniation is unlikely due to surgery.
Detailed Answer:
Hi, thanks for writing to XXXXXXX
Presence of arm pain & weakness suggests the compression of the
nerve root supplying that area in the
cervical spine, which is termed as
Radiculopathy.
The disc herniation that is showing up at C4 level is unlikely due to surgery (as ACDF perse will not produce disc protrusions). As the C5-C7 levels are fused, there occurs no movement at these levels. The immediate level above, where the movements tend to occur is C4 level.
So, during routine daily activities, more movement occurs at C4 level causing a disc herniation at that level.
The conservative management of your condition involves -
Soft Collar: Soft collar allow the muscles of the neck to rest and limit neck motion. This can help decrease pinching of nerve roots with movement. Soft collars should only be worn for
short periods of time, because long-term wear can decrease the strength of neck muscles.
Medicines:
Analgesic are needed in the acute phase. Muscle relaxants are essential for relieving muscle spasms once the acute pain subsides. Neurotropic vitamins like METHYLCOBALAMINE (activated Vit B12) or
PREGABALIN will help in alleviating the
neuropathic pain.
Physiotherapy: Once the acute phase of pain has subsided, Isometric strengthening exercises of the paravertebral muscles are started. Improving neck strength and flexibility with simple exercises may lessen discomfort and pain. Moist heat can be useful
Epidural steroids: are useful for patients with severe radicular pains in the limbs. Cortisone is a powerful anti-inflammatory preparation and so its injections in the "epidural space" can decrease swelling as well as pain.
