When one grows older, the disc starts to dry out and shrink, causing small tears in the annulus and inflammation of the nerve root.

[1][3] The neurosurgeon or orthopedic surgeon enters the space between two discs through a small incision in front (= anterior) of and at the right or left side of the neck.

Wearing the brace heightens one's awareness of posture and positioning and helps prevent movements (e.g., sudden and/or excessive bending or twisting of the neck) that may aggravate or slow down the healing process.

[citation needed] It is especially advisable to wear a protective neck brace when traveling (e.g., by car), sleeping, showering, or any other activities in which the patient may not be able to be ensure proper spinal alignment.

In addition, physical therapy and related healing modalities (e.g., massage, acupuncture) may be recommended in order to promote proper healing, as well as to strengthen the surrounding muscles that can take over the neck brace's 'job' of ensuring proper spinal alignment when the patient starts (around 4 to 6 weeks after surgery) to wean off the neck brace.
