  • Abstract
  • Look Inside

 Cervical laminoplasty is an excellent surgical procedure for the treatment of myelopathy secondary to multisegmental cord compression, although many patients experience its notorious postoperative complication:axial neck pain. To locate the cause of the axial pain, we prospectively allocated 91 myelopathy patients to undergo three different types of laminoplasty and investigated the incidence of axial pain in the left-opened C3-7 laminoplasty group (n=37), left-opened C3-6 laminoplasty group (n=31) and right-opened C3-6 laminoplasty group (n=23). The paravertebral muscles on the hinged side are all preserved in our original open-door laminoplasty technique. Significant axial neck pain developed in 30% of the patients after C3-7 laminoplasty, but the rate was only 7.5% after the C3-6 procedure (p=0.015). When we checked the slightest pain after the C3-6 procedure, it was predominantly on the side that was opened, although it dissolved spontaneously within a month. We concluded that there is little relationship between the paravertebral muscles and axial pain after laminoplasty, but that C7 is strongly associated with axial pain, and it should not be included in the procedure to prevent it.
