Clinical Trial Summary

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

Description:

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 Neck Disability Index(NDI), the Visual Analog Scale(VAS) of neck pain, and the C2-7 Spine Cobb angle at postoperative 1 year.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	the Neck Disability Index (NDI)	scores from 0 to 50 with 50 being the worst performance status related to neck pain.	1 year
Primary	posterior neck with visual analog scale (VAS)	Measuring pain intensity of the posterior neck with visual analog scale (VAS), rated 1 to 10 with 10 being the most severe pain level.	1 year
Primary	C2-C7 lordosis	Measuring C2-C7 lordosis angle by using standard lateral cervical x-ray series protocol with the patients standing in a neutral position and instructed to look straight ahead with knees locked.	1 year
Secondary	EuroQol five-dimensional questionnaire (EQ-5D) scores	Responses on a questionnaire with five dimensions, each comprised of five levels. Scores are revised into an index with a range from -0.59-1, with 1.00 indicating full health.
