Comparison Between C3-6 Laminoplasty and C3 Laminectomy With Cervical Laminoplasty

Randomized Controlled Trial: Comparison of Radiological and Axial Pain Outcome Between C3-6 Open Door Laminoplasty and C3 Laminectomy With Cervical Laminoplasty

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

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
