Update: Cervical laminoplasty

Cervical laminoplasty is an established treatment for cervical myelopathy.

Fields et al., 1) observed in their randomized study comparing the effects of cervical laminectomy and laminoplasty in the rabbit, that laminectomized animals had poorer clinical outcome at 3 months post-operatively, associated with statistically significant angular deformity.

Similarly, Baisden et al., 2) , using a goat model, concluded that laminoplasty is superior to laminectomy in maintaining sagittal cervical alignment and preventing spinal deformities. The removal of bony and ligamentous structures of the posterior cervical spine might alter the biomechanics of the vertebral column and predispose to instability.

History

The first laminoplasty technique was the modification of Kirita’s technique for laminectomy, in which the laminae were thinned and then partially removed in the midline using an air drill. The lateral edges of the laminae close to the pedicles were further thinned until the laminae could be bent and lifted up. It was considered important to lift multiple laminae expeditiously so that multiple segments of the cord could be simultaneously decompressed. The laminae were then removed with scissors 3)).

Based on this technique, Oyama et al. developed z-plasty method of laminoplasty. After thinning the laminae, z-shaped cuts were made in each laminae, which were lifted and then fixed with sutures to reconstruct the expanded spinal canal. They reported that all the 15 cases were neurologically improved after the operation 4)).

Tsuji reported a variation of en bloc laminectomy in which laminae were cut bilaterally along the imaginary line separating laminar arches and articular processes and made completely free from their bony attachments. The lamiae were reflected as a flap and then permitted to float on the cord without fixing sutures or bone grafting 5).

Expansive open-door laminoplasty was devised by Hirabayashi et al. in 1977, as relatively easier, safer, and better than the ordinary cervical laminectomy from the standpoint of structural mechanics of the cervical spine.

Operative results in the patients with cervical OPLL, spondylosis, and canal stenosis were satisfactory, and optimal widening of the AP diameter of the spinal canal is considered to be over 4 mm. From this procedure a bilateral, open-door laminoplasty has been devised for extensive exploration at the intradural space.

Cervical laminoplasty was devised to avoid problems associated with laminectomy such as postoperative segmental instability, kyphosis, perineural adhesions, and late neurological deterioration 6).

Kurokawa et al. developed spinous process splitting laminoplasty, in which the spinous processes and laminae are split in the midline and hinges are made bilaterally along the lateral borders of the laminae, which are lifted bilaterally 7)).

This is also called double-door laminoplasty 8), French-window 9) or French door laminoplasty 10)

There are multiple variations, many advocating the use of allograft, but for the best technique controversy persists.

Complications

Neck pain

Axial neck pain after C3-6 laminoplasty has been reported to be significantly lesser than that after C3-7 laminoplasty because of the preservation of the C-7 spinous process and the attachment of nuchal muscles such as the trapezius and rhomboideus minor, which are connected to the scapula. The C-6 spinous process is the second longest spinous process after that of C-7, and it serves as an attachment point for these muscles. The effect of preserving the C-6 spinous process and its muscular attachment, in addition to preservation of the C-7 spinous process, on the prevention of axial neck pain is not well understood. The purpose of the current study was to clarify whether preservation of the paraspinal muscles of the C-6 spinous process reduces postoperative axial neck pain compared to that after using nonpreservation techniques.

Montano et al. studied 60 patients who underwent C3-6 double-door laminoplasty for the treatment of cervical spondylotic myelopathy or cervical ossification of the posterior longitudinal ligament; the minimum follow-up period was 1 year. Twenty-five patients underwent a C-6 paraspinal muscle preservation technique, and 35 underwent a C-6 nonpreservation technique. A visual analog scale (VAS) and VAS grading (Grades I-IV) were used to assess axial neck pain 1-3 months after surgery and at the final follow-up examination. Axial neck pain was classified as being 1 of 5 types, and its location was divided into 5 areas. The potential correlation between the C-6/C-7 spinous process length ratio and axial neck pain was examined.

The mean VAS scores (± SD) for axial neck pain were comparable between the C6-preservation group and the C6-nonpreservation group in both the early and late postoperative stages (4.1 ± 3.1 vs 4.0 ± 3.2 and 3.8 ± 2.9 vs 3.6 ± 3.0, respectively). The distribution of VAS grades was comparable in the 2 groups in both postoperative stages. Stiffness was the most prevalent complaint in both groups (64.0% and 54.5%, respectively), and the suprascapular region was the most common site in both groups (60.0% and 57.1%, respectively). The types and locations of axial neck pain were also similar between the groups. The C-6/C-7 spinous process length ratios were similar in the groups, and they did not correlate with axial neck pain. The reductions of range of motion and changes in sagittal alignment after surgery were also similar.

The C-6 paraspinal muscle preservation technique was not superior to the C6-nonpreservation technique for preventing postoperative axial neck pain 11).

Case series

2017

Thirty-two consecutive patients (19 male, 13 female, average age 66 yr) from a prospective outcome registry that underwent cervical laminoplasty between 2009 and 2013 were reviewed. Computed tomography (CT) scan was performed immediately postoperatively and at 6-mo follow-up. Parameters included patient perception of outcome, Nurick score, Neck Disability Index (NDI), visual analog scale for neck pain, and SF-36.

On retrospective analysis, all patients felt improved at 3 mo postoperatively; at 2 yr, this rate was 91%. Improvements were seen in Nurick scores, from 3.16 ± 0.9 preoperatively to 1.94 ± 0.8 at 2 yr; NDI score from 28.7% ± 9% preoperatively to 20.8% ± 9.6% at 2 yr; visual analog scale from 2.8 ± 1.2 preoperatively to 1.7 ± 0.9 at 2 yr; and SF-36 physical component summary from 27.9 ± 10 preoperatively to 37.8 ± 11.9 at 2 yr. All values reached significance at all follow-up points ( P < .05) with the exception of 6-mo NDI values ( P = .062). No C5 palsy, graft complications, or reclosure was observed in any patient during the follow-up period.

Laminoplasty with autograft is a safe and effective method to treat cervical myelopathy, with good medium-term clinical outcome. No reclosures were observed. Bony fusion was seen in all cases on CT scan. The study found good outcomes in the performance of open door laminoplastywithout hardware, in the treatment of cervical stenosis 12).

2016

Sakaura et al., reported that the presence of chronic kidney disease (CKD) and/or extended abdominal aortic calcification was associated with significantly worse clinical outcomes after posterior lumbar interbody fusion. CKD is one of the highest risk factors for systemic atherosclerosis. Therefore, impaired blood flow due to atherosclerosis could exacerbate degeneration of the cervical spine and neural tissue. However, there has been no report of a study evaluating the deleterious effects of CKD and atherosclerosis on the outcomes after decompression surgery for cervical spondylotic myelopathy.

They analyzed data from 127 consecutive cases involving patients who underwent cervical laminoplasty for CSM and met their inclusion criteria. Stage 3-4 CKD was present as a preoperative comorbidity in 44 cases. Clinical status was assessed using the Japanese Orthopaedic Association (JOA) cervical myelopathy evaluation questionnaire before surgery and 2 years postoperatively. As a marker of systemic atherosclerosis, the presence of aortic arch calcification (AoAC) was assessed on preoperative chest radiographs.

AoAC was found on preoperative chest radiographs in 40 of 127 patients. Neither CKD nor AoAC had a statistically significant deleterious effect on preoperative JOA score. However, CKD and AoAC were significantly associated with reductions in both the JOA score recovery rate (mean 36.1% in patients with CKD vs 44.7% in those without CKD; 26.0% in patients with AoAC vs 48.9% in those without AoAC) and the change in JOA score at 2 years after surgery (mean 2.3 points in patients with CKD vs 3.1 points in those without CKD; 2.1 points for patients with AoAC vs 3.2 points for those without AoAC). A multivariate regression analysis showed that AoAC was a significant independent predictor of poor outcome with respect to both for the difference between follow-up and preoperative JOA scores and the JOA score recovery rate.

CKD and AoAC were associated with increased rates of poor neurological outcomes after laminoplasty for CSM, and AoAC was a significant independent predictive factor for poor outcome 13).

On a beautiful spring morning in 1989, neurosurgeon and spine expert Volker Sonntag was just finishing rounds at Saint Joseph’s Hospital in Phoenix, Arizona. At that same moment sixteen miles away, a hard-charging boy named TJ veered his bike into the path of a speeding pickup truck. The impact all but killed the boy, leaving him with a shattered leg, severe internal injuries, a massive blood clot near the brain stem, and—but for the fragile spinal cord—a complete separation of the skull from the spine.

This is the riveting story of how Dr. Sonntag’s pioneering innovation that day launched him into the forefront of the emerging field of spinal neurosurgery. Surgeon to a Who’s Who of royalty, celebrities and politicians, his clear-eyed accounts of failures and successes, hostile turf wars, media accusations of quackery, political challenges, and cutting-edge technical advances reveal to the reader just what it takes to be a game-changer in one of the world’s most harrowing professions.

Revered by patients, residents, and fellows for his highly personal approach to teaching and mentorship, and for his example of life balance, in this book Dr. Sonntag also shares stories of his youth as a German immigrant in Cold War America that lend insight into how, with humility, sacrifice, honesty, compassion, industry—and humor—an individual can overcome adversity and achieve the American Dream.

This unique and richly illustrated volume presents the state of the art in the comprehensive management of major neurosurgical diseases in the elderly (aged 65 and over). It explores all of the common neurosurgical pathologies affecting elderly patients, and emphasizes the paramount importance of tailored management strategies for quality of life. It highlights updated techniques for anaesthesia and critical care, as well as minimally invasive neurosurgical methods intended for this specific group of patients. Radiosurgery treatment is also discussed, in particular for brain tumours.
In western societies, the proportion of elderly citizens has nearly reached 20%, and shows no signs of slowing down. The management of neurosurgical conditions in this particular population requires specific multidisciplinary strategies. To address this situation, a team of internationally respected contributors accurately describe degenerative and traumatic spinal diseases, which account for the majority of admissions among the elderly, as well as brain tumours and intracranial haemorrhages, aspects that are raising new ethical issues.
The book mainly addresses the needs of neurosurgeons and geriatric neurologists, but also neuro-oncologists and neuro-anaesthesists working with elderly patients, as well as students in these disciplines.
