Abstract OPEN-DOOR EXPANSILE laminoplasty is a practical surgical technique for the treatment of cervical myelopathy secondary to cervical spinal stenosis. Laminoplasty procedures were first described in the late 1970s and have undergone numerous modifications. The current article reviews the indications, techniques, and outcome data for cervical laminoplasty. Complications of laminoplasty and comparison to laminectomy outcomes are also discussed.

Object This retrospective study was conducted to evaluate the prevalence and clinical consequences of postoperative lamina closure after open-door laminoplasty and to identify the risk factors. Methods Eighty-two consecutive patients with cervical myelopathy who underwent open-door laminoplasty without plates or spacers in the open side (Hirabayashi's original method) were included (62 men and 20 women with a mean age of 62 years and a mean follow-up of 1.8 years). In 67 patients the cause of cervical myelopathy was spondylotic myelopathy, and in 15 it was caused by ossification of posterior longitudinal ligament. Radiographic measurements were made of the anteroposterior diameters of the spinal canal and vertebral bodies from C3–6, and the presence of kyphosis were assessed. Lamina closure was defined as ≥ 10% decrease in the canal-to-body ratio at the final follow-up compared with that immediately after surgery at ≥ 1 vertebral level. The impact of lamina closure on neck pain, patient satisfaction, Japanese Orthopaedic Association scores, and recovery rates were also evaluated. Results The mean canal-to-body ratio at C3–6 was 0.69–0.72 preoperatively, 1.25–1.28 immediately after surgery, and 1.18–1.24 at the final follow-up examination. Lamina closure was observed in 34% of patients and was not associated with sex, age, or cause of myelopathy, but was significantly associated with the presence of preoperative kyphosis (p = 0.014). Between patients with and without lamina closure, there was no significant difference in preoperative (9.7 ± 3.1 vs 10.6 ± 2.5) and postoperative (13.7 ± 2.4 vs 13.1 ± 2.7) Japanese Orthopaedic Association scores, recovery rates (53.9 ± 29.9% vs 44.3 ± 29.5%), neck pain scores (3.5 ± 0.7 vs 3.3 ± 1.0), or patient satisfaction level (4.0 ± 1.4 vs 4.8 ± 1.0). Conclusions Lamina closure at ≥ 1 vertebral level occurred in 34% of patients. Although patients with lamina closure obtained equivalent recovery from myelopathy in a short-term follow-up, they tended to be less satisfied with surgery compared with those who did not have closure. The only significant risk factor identified was the presence of preoperative cervical kyphosis, and preventative methods for lamina closure, therefore, should be considered for patients with preoperative kyphosis.

Multilevel Cervical Myelopathy

BACKGROUND: At present, few reports are comparing these 2 major cervical posterior laminoplasty methods with Open-door and French-door Laminoplasty in terms of neurological recovery, cervical alignment, and surgical complications. Moreover, most of the research has not been well designed. AIM: This study aims to determine comparative effectiveness and functional outcome of open-door versus french-door laminoplasty for multilevel cervical myelopathy. METHODS: The Meta-analysis is used in this study. The study sample is a published research articles on comparative effectiveness and functional outcome of open-door versus french-door laminoplasty for multilevel cervical myelopathy on the internet through databases on PubMed and ProQuest and published between 1997 until December 2018. Weighted mean difference and pooled weighted mean difference are calculated by using the fixed-effect model or random-effect model. Data is processed by using Review Manager 5.3 (RevMan 5.3). RESULTS: This study reviews 58 articles. There are 6 studies conducted a systematic review and continued with Meta-analysis of relevant data. The results showed significant higher postoperative Japanese Orthopaedic Association (JOA) score in open-door laminoplasty (ODL) than French-door laminoplasty (FDL) (weighted mean difference [WMD] = 0.71; 95% confidence interval [CI]: 0.35 to 1.07; p < 0.05). The outcome of procedures treatment of multilevel cervical myelopathy revealed the operative time, cervical range of motion, axial canal diameter postoperative, axial pain reduction and complications events in ODL and FDL there was no significant difference. But for a cervical lordotic angle in ODL and FDL, there was a significant difference; the ODL group were significantly lesser than the FDL group. The recovery rate in ODL and FDL, there was a significant difference; the ODL was shown to be significantly higher than FDL (p < 0.05). CONCLUSION: This analysis suggests that neither cervical laminoplasty approach is superior, based on the postoperative radiological data and complication rate. But the open-door laminoplasty resulted in a higher functional outcome and recovery rate as compared to the French-door laminoplasty.

Abstract CERVICAL LAMINOPLASTY IS becoming a popular technique for the treatment of cervical myelopathy that is the result of multilevel canal stenosis. Many variations in this technique, which was originally created in Japan, have been developed, all with the goal of increasing canal space and reconstructing the posterior bony arch. We describe our extensive experience with this procedure for the treatment of cervical spondylotic myelopathy.

Object. Numerous surgical procedures have been developed for treatment of ossification of the posterior longitudinal ligament (OPLL) of the cervical spine, and these can be performed via three approaches: anterior, posterior, or combined anterior—posterior. The optimal approach in cases involving OPLL-induced cervical myelopathy, however, remains controversial. To address this issue, the authors assessed the benefits and limitations of expansive open-door laminoplasty for OPLL-related myelopathy by evaluating mid- and long-term clinical results. Methods. Clinical results obtained in 72 patients who underwent expansive open-door laminoplasty between 1983 and 1997 and who were followed for at least 5 years were assessed using the Japanese Orthopaedic Association (JOA) scoring system. The mean preoperative JOA score was 9.2 ± 0.4; at 3 years postoperatively, the JOA score was 14.2 ± 0.3 and the recovery rate (calculated using the Hirabayashi method) was 63.1 ± 4.5%, both having reached their highest level. These favorable results were maintained up to 5 years after surgery. An increase in cervical myelopathy due to progression of the ossified ligament was observed in only two of 30 patients who could be followed for more than 10 years. Severe surgery-related complications were not observed. Preoperative JOA score, age at the time of surgery, and duration between onset of initial symptoms and surgery affected clinical results. Conclusions. Mid-term and long-term results of expansive open-door laminoplasty were satisfactory. Considering factors that affected surgical results, early surgery is recommended for OPLL of the cervical spine.
