Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Investigators performed a prospective randomized controlled trial for comparing postoperative clinical and radiological outcomes between C3 laminectomy with laminoplasty and C3-6 laminoplasty.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cervical laminoplasty is widely performed surgical techniques to cervical myelopathy patients. But it is well known that C3-6 Cervical laminoplasty often results in injury of the semispinalis cervicis inserted into the axis, which possibly causes postoperative cervical kyphosis and neck pain. C3 laminectomy with cervical laminoplasty is the modified technique preserving the semispinalis cervicis to reduce such complications of conventional C3-6 laminoplasty.

There has been a number of retrospective studies comparing C3 laminectomy with laminoplasty and C3-6 laminoplasty, however, there's no prospective randomized controlled study yet. Investigators performed a prospective randomized controlled trial for comparing postoperative clinical and radiological outcomes between C3 laminectomy with laminoplasty and C3-6 laminoplasty. Primary end points include the C2-7 spine cobb anlge, Neck Disability Index(NDI) at postoperative 1\~3 year

SINGLE

Participants
Using a generator of www.randomization.com, 100 subjects randomized into blocks of 50 and 50. To reproduce this plan, use the seed 3169 along with the number of subjects per block/number of blocks and (case-sensitive) treatment labels as entered originally.

and (case-sensitive) treatment labels as entered originally. After randomization of 100 subjects, additional 26 subjects randomized into blocks of 13 and13. To reproduce this plan, use the seed 5134 along with the number of subjects per block/number of blocks and (case-sensitive) treatment labels as entered originally.
