[Progress on laminoplasty in spinal canal disease]

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Spinal Surgery

Background:

• Spinal canal disease requires surgical intervention, with laminectomy and laminoplasty being common procedures.
• Maintaining spinal biomechanical stability is crucial for ideal surgical outcomes.
• Clinician approaches to spinal stabilization during surgery vary, making it a research focus.

Purpose of the Study:

• To compare the efficacy of laminectomy and laminoplasty in treating spinal canal disease.
• To evaluate the impact of surgical techniques on spinal biomechanical stability.
• To determine the ideal surgical method for single spinal canal disease, considering stability.

Main Methods:

• Review of surgical techniques including laminectomy and laminoplasty.
• Analysis of methods aimed at reducing the impact of laminectomy on spinal stability.
• Evaluation of laminoplasty's ability to decompress neural elements and maintain stability.

Main Results:

• Laminoplasty increases vertebral canal volume, relieving nerve root compression.
• Laminoplasty allows spinal cord migration, reducing contact with disc and vertebral bodies.
• Laminoplasty can potentially prevent postoperative spinal instability.

Conclusions:

• Laminoplasty is theoretically the most ideal method for single spinal canal disease.
• This technique is particularly advantageous in cases with extensive disease, severe bone destruction, or osteoporosis.
• Laminoplasty offers both decompression and preservation of spinal stability.
