“…The clinical outcomes obtained with this modified technique were as good as those in other studies, judging by the recovery rates given in the literature (Naito et al 1994, Yue et al 2000, Park and Heller 2006. Postoperative interlaminar bony fusion with reduced cervical ROM has been reported to occur in patients undergoing laminoplasty (Seichi et al 2001, Kawaguchi et al 2003, Iizuka et al 2006).…”

Background and purpose In the classic Hirabayashi procedure, the lamina door is tethered open by sutures between the spinous process and facet capsule or paravertebral muscle. Our early experiences showed, however, that the loosened sutures result in dislodgement and reclosure of the lifted lamina. We present a modified method to ensure secure fixation and prevent restenosis due to hinge closure.Patients and methods 12 patients with cervical spondylotic myelopathy underwent unilateral open-door laminoplasty using suture anchor fixation between 2000 and 2004. The sutures were tied and fixed onto the holed lateral mass screws, instead of using the conventional suture technique. We used radiography, MRI, and CT for imaging studies. The Nurick score was used to assess severity of myelopathy, and the Japanese Orthopedic Association (JOA) score was used to evaluate clinical outcomes before surgery and at the last follow-up visit.Results All patients experienced functional improvement of at least 1 Nurick score after surgery. The JOA score for the 12 patients increased significantly from 6.9 (SD 3.0) before surgery to 13 (SD 1.6) at final follow-up. Postoperative radiography and CT showed increased sagittal diameter and canal expansion. Average preoperative and postoperative ranges of motion for the cervical spine were 48 (SD 4.6) and 36 (SD 2.7), respectively. No neurological deterioration due to hinge reclosure and no major surgery-related complications were observed during the follow-up period.Interpretation Open-door laminoplasty using suture anchor fixation effectively maintains expansion of the

“…It has also been considered relatively safe, with a low risk of complications. [1][2][3][4] Several kinds of laminoplasty have been described in the past 20 years; these techniques aim at preventing the complications seen with laminectomy. [5][6][7][8][9] Laminoplasty procedures can be roughly classified into unilateral or single-door laminoplasty, and spinous processes-splitting or double-door laminoplasty.…”

Our investigation provides insight into canal expansion after laminoplasty. The increased amount of canal following laminoplasty can be predicted by the regression equations. This may allow preoperative determination of the optimal size of the opening needed to establish adequate canal space for the spinal cord. Both single and double-door techniques of laminoplasty provide sufficient room for posterior migration of the spinal cord, although gaining different canal expansion.

“…Peck 14 and MacCartee 15 have reported cases of thoracic calcified nucleus pulposus that had ruptured into the spinal canal, causing signs of cord compression, relieved by laminectomy. Although laminoplasty for similar types of cord compression without the calcification has been reported, [16][17][18] there has been no report to date on this disease at the cervical-thoracic junction treated by this method.…”

Calcified intervertebral disc herniation in a child with myelopathy treated with laminoplasty

Study design: Case report. Objective: To describe a case of pediatric calcified intervertebral disc herniations at the cervical-thoracic junction surgically treated with laminoplasty. Methods: A 13-year-old girl with calcified intervertebral disc herniations at C7/Th1 and Th1/2 causing myelopathy was performed with laminoplasty . Results: Postoperative course was without complication, and the neurologic examination returned to a completely normal state at 5 years to date after surgery. Conclusions: Laminoplasty produced an excellent result and is a consideration for treatment of similar cases of calcified intervertebral disc herniation.Spinal Cord (2005) 43, 680-683.
