[Cervical Cord/Root Decompression:Posterior Approach/Variation of Surgical Procedure].

Posterior cervical decompression surgery is safe and effective. It was developed to safely and reliably decompress nerve tissues. Maximising the reconstruction and maintenance of the posterior neck tissue has been reported and developed. Complete reconstruction of the posterior musculoskeletal unit can minimise postoperative complications and spinal alignment changes. Here, we introduced laminoplasty which completely preserved the posterior cervical spinal tissue, and discussed its variations. Although posterior cervical decompression is a basic and safe surgical technique that can be used in many diseases, it has limitations. The factors of nerve compression should be carefully examined, and the most appropriate procedure should be selected considering total spinal alignment.
