BACKGROUND: Laminoplasty is a surgical procedure frequently performed for cervical myelopathy. We investigated correlations between changes in the anteroposterior diameter (APD) of the spinal canal, spinal canal area (SCA), and laminar angle (LA) and clinical outcomes of laminoplasty. METHODS: Of the 204 cervical myelopathy patients who underwent laminoplasty from July 2010 to May 2015, 49 patients who were evaluated with pre- and postoperative computed tomography of the cervical vertebrae were included...

OBJECTIVE: For three or more involved cervical levels, there is a debate over which approach yields the best outcomes for the treatment of multilevel cervical degenerative disease. Our objective is to compare the radiological and clinical outcomes of two treatments for multilevel cervical degenerative disease: anterior cervical discectomy and fusion (ACDF) versus plate-only open-door laminoplasty (laminoplasty). METHODS: Patients were randomized on a 1:1 randomization schedule with 17 patients in the ACDF group and 17 patients in the laminoplasty group...

STUDY DESIGN: Prospective randomized controlled study OBJECTIVES.: To determine the effect of collar-aided fixation on outcomes following laminoplasty for cervical compressive myelopathy. SUMMARY OF BACKGROUND DATA: Patients are often placed in a Philadelphia collar for weeks after cervical laminoplasty. However, the benefit of postoperative collar use remains controversial. We hypothesized that treatment outcomes in postoperative pain in patients without collars would not be inferior to the outcomes in patients using Philadelphia collars for two weeks...

STUDY DESIGN: A post-hoc comparative study OBJECTIVE.: To evaluate postoperative clinical, radiological, and surgical outcomes after LP involving the C3 segment and to compare outcomes with those of patients who underwent LP with C3 LN. SUMMARY OF BACKGROUND DATA: In many of the pathologies that require LP involving C3 segment, most spine surgeons perform LP at C3 as well as other cervical segments. Considering the peculiarities of the C2-C3 level, spine surgeons should take into account those in LP involving the C3 segment, but the particular aspects of the C2-C3 levels have not been fully evaluated...

OBJECTIVE: The aim of this study was to compare the clinical and radiological outcomes associated with the use of hydroxyapatite (HA) spacer and allogeneic bone (AB) spacer in laminoplasty. METHODS: From January 2006 to July 2014, 79 patients with cervical spondylotic myelopathy or ossification of the posterior longitudinal ligament underwent cervical laminoplasty. The radiologic parameters were obtained from plain radiography and three-dimensional computed tomography...

STUDY DESIGN: Retrospective study. OBJECTIVES: Few studies have reported a relationship between central motor conduction time (CMCT), which evaluates corticospinal function, and degree of spinal cord compression in patients with myelopathy. Thus, there is no consensus on predicting the degree of prolonged CMCT on the basis of the degree of spinal cord compression. If a correlation exists between CMCT and spinal cord compression, then spinal cord compression may be a useful noninvasive clinical indicator of corticospinal function...

STUDY DESIGN: Retrospective study. OBJECTIVE: This study investigated the pathophysiology of compressive cervical myelopathy (CCM) with prolonged central motor conduction time (CMCT) in the upper limbs (UL) rather than lower limbs (LL) and prolonged CMCT at the thoracic level (TL). SUMMARY OF BACKGROUND DATA: Earlier reports indicated the usefulness of CMCT to assess preoperative CCM severity. However little information exists on patients with prolonged CMCT-UL rather than CMCT-LL and prolonged CMCT-TL...

Study Design Systematic review. Objective To compare laminoplasty versus laminectomy and fusion in patients with cervical myelopathy caused by OPLL. Methods A systematic review was conducted using PubMed/Medline, Cochrane database, and Google scholar of articles. Only comparative studies in humans were included. Studies involving cervical trauma/fracture, infection, and tumor were excluded. Results Of 157 citations initially analyzed, 4 studies ultimately met our inclusion criteria: one class of evidence (CoE) II prospective cohort study and three CoE III retrospective cohort studies...

BACKGROUND: C5 nerve root palsy is a known complication after cervical laminectomy or laminoplasty, characterized by weakness of the deltoid and bicep brachii muscles. The efficacy of intraoperative monitoring of these muscles is currently unclear. In the current prospective study, intraoperative monitoring through somatosensory (SSEPs), motor (TcMEPs) evoked potentials and real-time electromyography activity (EMG) were analyzed for their ability to detect or prevent deltoid muscle weakness after surgery...

STUDY DESIGN: Systematic review and meta-analysis of studies for the treatment of cervical myelopathy with OPLL treated with laminoplasty or fusion. OBJECTIVE: To delineate whether OPLL continues to progress after laminoplasty compared with fusion and to clarify the relationship between radiological progression of OPLL and neurological decline. SUMMARY OF BACKGROUND DATA: Laminoplasty is usually performed in patients with multilevel ossification of the posterior longitudinal ligament (OPLL) due to the surgical morbidity of anterior surgery...

STUDY DESIGN: A retrospective evaluation of sagittal angular motion from cervical spinal flexion to extension. OBJECTIVE: To evaluate the kinematic effects of cervical laminoplasty for cervical spondylotic myelopathy (CSM) on the occipitoatlantoaxial junction. SUMMARY OF BACKGROUND DATA: The kinematic effects of cervical laminoplasty for CSM on the occipitoatlantoaxial junction remain controversial. METHODS: A total of 65 CSM patients who were treated with cervical laminoplasty ranging from the C3 to C7 vertebrae were included in the study...

BACKGROUND Postoperative axial symptoms (post-AS) after single-door cervical laminoplasty for cervical spondylotic myelopathy (CSM) are a common and severe complication that adversely affects normal daily activities. Their etiology remains unclear. It is important to know which preoperative factors are the most predictive of post-AS. Therefore, this study aimed to elucidate the preoperative factors affecting post-AS. MATERIAL AND METHODS A total of 102 patients with CSM who underwent single-door cervical laminoplasty between 2009 and 2015 were studied...

BACKGROUND CONTEXT: The time of onset of postoperative upper limb palsy (ULP), also referred to as C5 palsy, varies among patients. Although some studies addressed the relationship between the time of onset of ULP and the potential etiologies, no meta-analysis has been conducted regarding the association between the time of onset of ULP and other factors such as surgical procedure type and treated diseases. PURPOSE: This study aimed to elucidate differences in the time of onset of ULP among spinal surgical procedures and treated diseases to understand its etiology...

BACKGROUND: Our study was aimed at finding out if Runx2 SNPs (single-nucleotide polymorphisms) are related to susceptibility to and prognosis of ossification of posterior longitudinal ligament (OPLL). METHODS: We selected 80 OPLL patients and another 80 independent patients without OPLL from September 2013 to November 2014. Serum was collected to detect the genotypes of rs1321075, rs12333172, and rs1406846 on Runx2 with direct sequencing analysis. RESULTS: Differences in clinical characteristics, including age, weight, height, sex ratio, as well as smoking and drinking history, between OPLL and control groups appeared to be insignificant (all P-value >...

Although several studies report various treatment solutions for cervical spondylotic myelopathy in patients with athetoid cerebral palsy, long-term follow-up studies are very rare. None of the reported treatment solutions represent a gold standard for this disease owing to the small number of cases and lack of long-term follow-up. This study aimed to evaluate the outcomes of laminoplasty with lateral mass screw fixation to treat cervical spondylotic myelopathy in patients with athetoid cerebral palsy from a single center...

Spinal kyphotic deformity after spinal laminectomy or laminoplasty is more common in pediatric patients than adults. Laminectomy can lead to decreased cartilage growth, anterior wedging and posterior spinal muscle insufficiency which can result in kyphotic deformity. Herein we outline a case report of a child presenting with kyphotic deformity after receiving a spinal laminectomy to treat a penetrating spinal trauma. The 8-year-old male presented with penetrating spinal trauma following a gunshot wound and subsequently underwent L1 laminectomy and thecal sac decompression to remove the foreign body...
