BACKGROUND: Laminoplasty and laminectomy are two common surgical procedures utilized in approaching degenerative and neoplastic disease of the spinal canal. Routinely adopted instruments, such as Kerrison rongeur or high-speed drill (HSD), entail some potentially serious complications such as dura injuring and thermal and mechanical damage to neurovascular structures. We have adopted piezoelectric bone surgery, which permits a selective cut of mineralized tissues, to perform posterior procedures on the thoracic spine, where the relationship between bone and the spinal cord are critical...

BACKGROUND CONTEXT: Despite the fact that ossification of posterior longitudinal ligament (OPLL) is a three-dimensional disease, conventional studies have mainly focused on a two-dimensional measurement, and it is difficult to accurately determine the volume of OPLL growth and analyze the factors affecting OPLL growth after posterior decompression (laminoplasty or laminectomy and fusion). PURPOSE: This study aimed to investigate the factors affecting OPLL volume growth using a three-dimensional measurement...

OBJECTIVE: This research aimed to gain a better understanding of the relationship between cervical posterior open-door laminoplasty on axial symptoms, the net cross-sectional area of paraspinal muscles, and the degree of pimelosis. METHOD: A retrospective study was conducted on a consecutive series of 37 patients who had underwent cervical posterior open-door laminoplasty + lateral mass fixation and bone graft fusion between January 2015 and July 2015. All patients received postoperative examinations at 6 months and 18 months after the operation...

Cervical laminoplasty was initially described for the management of cervical myelopathy resulting from multilevel stenosis secondary to ossification of the posterior longitudinal ligament. The general concepts are preservation of the dorsal elements, preservation of segmental motion, and expansion of the spinal canal via laminar manipulation. No clear evidence suggests that laminoplasty is superior to either posterior laminectomy or anterior cervical diskectomy and fusion. However, laminoplasty has its own advantages, indications, and complications...

RATIONALE: Cervical open-door laminoplasty can enlarge the volume of the cervical vertebral canal and thus has become an effective and safe treatment for multilevel cervical disc herniation and cervical stenosis. Some post-surgery complications exist, such as reduction of cervical alignment and local kyphosis. However, aggravation of cervical disc herniation at the surgical level during short-term follow-up has not been discussed. Additionally, spontaneous disappearance of herniated disc pulposus is a common phenomenon in the lumbar region but is relatively rare in the cervical region...

INTRODUCTION: Solitary fibrous tumor (TFS) is a rare tumor of mesenchymal origin, located mainly in the pleura. It is extraordinarily infrequent find it at the intraespinal level, being the thoracic region the most frequent. CASE PRESENTATION: We present the case of a 48-year-old patient with progressive ascending lower limb and myelopathy of one month of evolution, with intraspinal location at the D3-D4 level. It was surgically operated by posterior dorsal approach and D3-D4 laminoplasty, with an intradural tumor with an intramedullary component of approximately 18×12mm...

PURPOSE: To compare the clinical and radiological outcomes between skipped-level and all-level plating for cervical laminoplasty. METHODS: Patients with cervical spondylotic myelopathy (CSM) treated by open-door laminoplasty with minimum 2-year postoperative follow-up were included. All patients had opening from C3-6 or C3-7 and were divided into skipped-level or all-level plating groups. Japanese Orthopaedic Association (JOA) scores and canal measurements were obtained preoperatively, immediate (within 1 week) postoperatively, and at 2, 6 weeks, 3, 6 and 12 months postoperatively...

Nondysraphic intramedullary spinal cord lipomas are even rarer. We present a thoracic intramedullary lipoma which spontaneously decreased in size following surgical debulking. A 3-year-old girl was admitted to our department with complaints of back pain since 1 year and progressive difficulty in walking since 6 months. Her magnetic resonance imaging (MRI) revealed T8-9 intramedullary mass showing increased signal intensity in both T1- and T2-weighted images. The patient was operated with a T8-9 laminoplasty and debulking, and internal decompression of the tumor was made...

A previously healthy 13-year-old girl presented with a 9-day history of acute onset severe neck pain associated with limited range of movement. Medical evaluation at day 2 was suggestive of muscle contracture, and she was discharged home with diazepam, antiinflammatory agents, and rest; however, she returned because of progressive clinical worsening with left arm distal paresthesia and paralysis since day 3. There was no history of trauma or other systemic complaints, and her familial medical history was unremarkable...

BACKGROUND The efficacy of laminoplasty in patients with cervical kyphosis is controversial. The purpose of this study was to investigate the impact of the initial pathogenesis on the clinical outcomes of laminoplasty in patients with cervical kyphosis. MATERIAL AND METHODS A total of 137 patients with cervical spondylotic myelopathy (CSM) or ossification of the posterior longitudinal ligament (OPLL) underwent laminoplasty from April 2013 to May 2015. The patients were divided into the following 4 groups: lordosis with CSM (LC), kyphosis with CSM (KC), lordosis with OPLL (LO), and kyphosis with OPLL (KO)...

PURPOSE: Addition of posterior instrumented fusion to laminoplasty (posterior decompression with instrumented fusion: PDF) can improve the surgical outcome of patients with K-line (-) cervical ossification of the longitudinal ligament (OPLL) compared with laminoplasty alone. We sought to elucidate the factors that are significantly associated with a better outcome after PDF for K-line (-) OPLL. METHODS: The present study included 38 patients who underwent PDF for K-line (-) OPLL and were followed up for at least 1 year after surgery...

Postoperative posterior spinal cord shift (PSS) has been considered a required radiographic endpoint of posterior decompression procedures. To achieve PSS, laminoplasty for cervical compressive myelopathy (CCM) has been consecutively performed on four or more laminae (C2-C7, C3-C7, or C3-C6). However, the clinical significance of PSS remains controversial. By selecting the surgically treated laminae, selective laminectomy (SL) can achieve adequate decompression without disturbing the extensor musculature and facet joints...

BACKGROUND: Little data is available about comparison of the incidence and clinical characteristics of the C5 palsy between patients of cervical myelopathy with occupying ratio greater than 50% and those with occupying ratio less than 50% following laminoplasty. METHODS: One-hundred eighteen patients with cervical myelopathy who underwent open door laminoplasty were reviewed in this study. The patients were divided into two groups: group A comprising 55 patients with an anterior occupying ratio greater than 50% and group B comprising 63 patients with an anterior occupying less than 50%...

RATIONALE: Acute neurological deficits following spinal surgery commonly result from epidural hematoma, surgical trauma, vascular compromise, and graft or hardware impingement, with the cause identified by magnetic resonance imaging (MRI). We present a rare case of dynamic paraspinal muscle impingement after C1 posterior arch laminectomy, which was diagnosed by myelography, with no significant findings on MRI. PATIENT CONCERNS: An 81-year-old, severely obese male, was referred to our department for the treatment of vertebral disease of the lumbar spine...

BACKGROUND: Ossification of the posterior longitudinal ligament (OPLL) often leads to cervical myelopathy. While multiple procedures have been shown to be effective in the treatment of OPLL, outcomes are less predictable than in degenerative cervical myelopathy and surgery is associated with high rates of complications and re-operation which affect quality of life. In this study, we perform a decision analysis utilizing post-operative complication data and health-related quality of life (HRQoL) utility scores to assess the average expected health utility and 5-year quality-adjusted life years (QALYs) associated with the most common surgical approaches for multilevel cervical OPLL...
