“…A variety of modified laminectomy and laminoplasty have been introduced as an alternative option of total laminectomy. Several reported methods include the hemi-laminectomy and hemi-laminoplasty [ 8 , 23 – 25 ], process-splitting hemi-laminoplasty [ 9 ] and the lamina fenestration [ 26 ]. Beside, Csaba et al [ 27 ] have performed that different intramedullary pathologies which located in the midline of the spinal canal resection with the para-split laminotomy approach, by which certain surgical results are achieved.…”

Background The open-door laminoplasty is an effective procedure for the treatment of cervical spondylotic myelopathy. However, little information is available about the surgical results of open-door laminoplasty in the treatment of intraspinal tumors. In the present study, we aimed to investigate the clinical effect of open-door laminoplasty with ARCH plate fixation in the treatment of cervical intraspinal tumors. Methods This was a retrospective study. From January 2013 to May 2018, 38 patients (13 males and 25 females, the average age of 44 ± 17 years) with cervical intraspinal tumors underwent open-door laminoplasty with ARCH plate fixation in our hospital. The operation time, blood loss, pre- and postoperative visual analog scale (VAS), and Japanese Orthopedic Association (JOA) scores were determined. To determine the radiographic outcomes, cervical X-ray film and magnetic resonance imaging (MRI) were performed before and after the operation, and cervical X-ray sagittal film was used to measure Cobb angle. The clinical data before and after the operation were compared by t-test. Results A total of 38 patients underwent a successful operation and demonstrated primary healing. The average operation time was 113 ± 12 min. The average blood loss was 120 ± 19 mL. All patients were followed up for 26.1 ± 2.8 months, and the final follow-up time was more than 24 months. VAS scores were much better at 24 months after operation compared with those before the operation, which were decreased from 6.1 ± 1.1 to 1.4 ± 0.7 (t = 32.63, P < 0.01). The JOA score was improved from 9.9 ± 1.5 to 15.5 ± 0.6 (t = − 18.36, P < 0.01), and the mean JOA recovery rate was 79% ± 11% at 24 months after the operation. There was no significant difference in Cobb angle between pre-operation and 24 months after the operation, which was 9.8 ± 2.6 and 10.3 ± 3.1 respectively (t = − 0.61, P > 0.05). Neither spinal malalignment on the coronal plane nor displacement of the laminoplasty flap was observed on postoperative cervical X-ray and MRI examinations at the final follow-up. Conclusions Open-door laminoplasty with ARCH plate fixation was a safe and effective surgical approach for the treatment of cervical intraspinal tumors.

“…Watanabe et al first described this technique in 2001 [17]. This technique is relatively largely used, especially in Japan, South Korea, and some centers in the US, Canada, and India, as described in the literature [18,11,10,16,5,7,9,3,6,1,8,4,19,13,14].…”

Background Laminotomy for lumbar stenosis is a well-defined procedure and represents a routine in every neurosurgical department. It is a common experience that the mono- or bilateral paraspinal muscles detachment together with supra and interspinous ligaments injury can lead to postoperative pain. In literature has been reported the application at the level of the lumbar spine of a minimally invasive technique defined as lumbar spinous process-splitting technique (LSPST). Methods In the current study, we present a case series of 12 patients that underwent LSPSL from September 2019 to April 2020. Two patient suffering from ligamentum flavum cyst, 8 patients with single level lumbar canal stenosis (LCS) and two patients with two-level LCS. The approach was mini-open, with reduced soft tissue dissection and without paraspinal muscles injury. Moreover, a novel morphological classification of postoperative muscle atrophy is proposed as well as a volumetric analysis of the decompression achieved. Conclusion At our knowledge, this is the first description of this surgical technique and the first LSPSL case series in Europe. Furthermore, cases of ligamentum flavum cyst removal using this safe and effective technique are not yet reported.

“…At present, more and more surgeons are aware of the importance of reconstruction of spinal stability and reducing postoperative complications for postoperative recovery and quality of life of patients, and pay great attention to the maintenance of spinal stability during operation. Following the introduction of lamina replantation by Raimondi in 1976 5 , a series of laminoplasty has been developed for intraspinal tumor resection [6][7][8][9][10] . By preserving some or all of the posterior column elements, these techniques restore the stability and integrity of the posterior column structure of spine and significantly reduce the complications of classical total laminectomy.…”

“…In addition, Csaba et al 16 have reported that para-split laminotomy approach can be used to explore different intramedullary pathologies located in the midline of the spinal canal. Lee et al 8 have reported spinous process-splitting hemi-laminoplasty for intradural and extradural lesions. The common advantages of these procedures include little effect on the extent of laminectomy and the stability of the spine.…”

Objective: To investigate the bone fusion and clinical effect of laminoplasty combined with ARCH plate fixation in the treatment of lumbar intraspinal tumors. Methods: This was a clinical study. From June 2017 to January 2019, 24 patients (seven males and 17 females, average age 40 ± 16 years) with lumbar intraspinal tumors underwent laminoplasty combined with ARCH plate fixation in our hospital. The bone fusion was evaluated by X-ray and computed tomography (CT) scans that were taken 15.2 ± 2.17 months postoperatively. Each segment showed a bone bridge on one side, which was classified as "segmental partial fusion." Each segment showed bilateral bone bridges, which were classified as "segmental complete fusion". When all segments of the patient showed bilateral bone bridging so that the replanted lamina and the host lamina became a unit on the CT scan, it was defined as "complete fusion". In addition, the operation time and blood loss were recorded. Fisher's exact test was used to analyze the potential influencing factors of bone healing, including age (≤40 years vs >40 years), gender, number of operated levels (single vs two). Paired t-test was used to analyze pre-and postoperative Oswestry Disability Index (ODI) scale and low back and leg pain visual analog scale (VAS). Results: A total of 33 segments of laminoplasty were successfully performed in 24 patients. The average operation time was 128 ± 18 minutes. The average blood loss was 110 ± 19 mL. All patients were followed up at least 12 months after operation (average, 15.2 ± 2.17 months). At the final follow-up, according to the definition of this study, the proportion of "segmental partial fusion" and "segmental complete fusion" were 30.3% (10/33) and 69.7% (23/33), respectively. And the proportion of patients with "complete fusion" was 70.8% (17/24). Age, gender, and number of operated levels were not associated with the fusion (P = 1.0, 0.37, and 0.06, respectively). ODI and VAS were much better at 1 month after operation and the final follow-up than those before the operation (P < 0.01). At 6 months after operation, the results of magnetic resonance imaging (MRI) showed that the supraspinous ligament was repaired, and there were no complications, such as spinal epidural scar recompression. Conclusions: Laminoplasty combined with ARCH plate was a better surgical method, and 70.8% of the patients showed complete bone fusion and there was no case of bilateral nonunion.
