Posterior Cervical Foraminotomy is used when the nerve root itself is compressed causing nerve pain (radiculopathy). If you have neck pain as your major complaint, a posterior cervical foraminotomy is unlikely to yield much neck pain relief. You could consider an artificial disc replacement (ADR) as long as you are a candidate (certain mechanical findings) or even facet blocks and radio-frequency ablation if indicated.
