The cervical spine, or simply the neck, is an intricate structure responsible for supporting the head and allowing its mobility. Over time, degenerative disc disease, herniated discs, and other cervical spine conditions can cause pain, numbness, weakness, and debility. For many, cervical disc replacement offers a promising solution.
Understanding Cervical Disc Replacement
Cervical disc replacement surgery, also known as cervical arthroplasty, involves the removal of a diseased cervical disc and its subsequent replacement with an artificial disc. This modern medical procedure is an alternative to the traditional method where the affected disc was removed, and the vertebrae above and below were fused, restricting motion. The goal of this surgery is to maintain the natural movement of the cervical spine.
Patients suffering from symptoms such as pain, pins and needles, numbness, or weakness in the neck, shoulders, or arms, may have a cervical herniated disc. This condition arises when the outer portion of the disc ruptures, causing some of the softer disc nucleus material to protrude. In severe cases, a large disc herniation might compress the spinal cord within the spinal canal, leading to numbness, stiffness, and weakness in the legs.
Those with diseased discs in the cervical spine who retain good spinal motion and have minimal arthritis can be excellent candidates for disc replacement surgery. Additionally, research from HSS suggests that patients with greater height in their spinal discs might have better outcomes than those with less disc height.
Post-Surgery Recommendations
Post-operatively, it’s crucial for patients to maintain an erect posture throughout the day. Regular position changes are encouraged, and sitting should be limited to 30-minute intervals. Patients are advised to practice appropriate body mechanics during their daily activities and should adhere to weight restrictions, typically less than 10 lbs. Additionally, the focus should be on reestablishing neuromuscular control of cervical and scapulothoracic muscle stabilizers, improving upper extremity and cervical mobility, and gradually weaning off collar usage.
Alternative Treatments
An alternative to cervical disc replacement is the anterior cervical discectomy. This procedure involves removing a herniated cervical disc through a small incision in the front of the neck. The space left behind can be filled with bone graft material, and in some cases, plates or screws can be implanted for increased stability. The most common operation for this is called an anterior cervical discectomy and fusion (ACDF), where the disc is removed, relieving any pressure on the spinal cord and nerve roots.
In Conclusion
Cervical disc replacement is a groundbreaking procedure that can offer relief to those suffering from debilitating cervical spine conditions. By understanding the procedure and adhering to post-surgery recommendations, patients can hope for improved mobility and a significant reduction in pain.
