Brief Summary
In 2006, our hospital improved and began to use cervical expansive open-door laminoplasty preserving the unilateral ligament with muscle complex.The effect of recent follow-up, postoperative complications and their effects on posterior cervical muscle volume were also studied.However, there are few reports about medium and long-term follow-up.
