Cervical Artificial Disc Replacement (ADR)

Cervical Artificial Disc Replacement (ADR) is a procedure used to treat certain neck conditions when non-surgical methods are no longer effective. It involves replacing a worn or damaged disc with an artificial one to relieve nerve compression. Compared to Anterior Cervical Discectomy and Fusion (ACDF), which limits motion by fusing vertebrae, ADR allows for greater preservation of neck mobility.

What is Cervical Artificial Disc Replacement?

Cervical artificial disc replacements (ADR) is an advanced surgical technique aimed at preserving motion and replacement of compromised intervertebral discs with a prosthetic joint.

Careful patient selection is required for this form of surgery to maximize results. The benefits of this surgery for nerve compression at the neck level when performed in suitable patients include:

• Maintaining movement at the level
• Faster return to work compared to fusion surgery
• Reduced stress on surrounding levels in the future compared to fusion surgery. 

The choice between fusion (ACDF) and replacement (ADR) surgeries for cervical spine issues should be made after a comprehensive review.

Indications for Cervical Artificial Disc Replacement

This procedure is typically recommended for individuals with the following clinical indications:

• Intractable pain (Cervical radiculopathy) with failure of conservative management
• Progressive hand clumsiness and gait unsteadiness (Cervical Myelopathy)
• Severe compression on nerves
• Presence of neurological deficits such as numbness or weakness

Cervical Artificial Disc Replacement Procedure

During the procedure, a small incision is made over the front of the neck. Careful dissection is performed to prevent potential injuries to internal structures. 

The offending disc material and bone spurs causing compression are removed, thus achieving pain and symptom relief. 

The artificial disc is implanted. The design of this artificial disc aids in preserving motion within that segment of the spine.

Recovery and Rehabilitation

Recovery from Cervical Artificial Disc Replacement is generally quicker than fusion surgery and involves a period of rest, activity modification, and physiotherapy. Many patients return to light daily activities within a few weeks, with gradual improvement in neck mobility and symptom relief.

Rehabilitation is personalised and may include guided exercises to restore motion, strengthen the neck and upper back, and support long-term spinal function.
