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...

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 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: To elucidate differences in the time of onset of ULP among spinal surgical procedures and treated diseases to understand its etiology...

OBJECTIVE: Scarcity of implants during the economic crisis has partially replaced cervical spondylotic myelopathy decompression and instrumented fusion with implant-less expansile cervical laminopalsty. The aim of the study was comparison of the results obtained with instrumented anterior cervical corpectomy and fusion (ACCF) with implant-less expansile cervical laminoplasty (ECL). METHODS: Patients suffering from cervical spondylotic myelopathy (CSM) Nurick 3-5, with preoperative tethering and postoperative untethering were included...

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...

STUDY DESIGN: A single-center, retrospective, longitudinal matched cohort clinical study of prospectively collected outcomes. OBJECTIVE: To compare retrospectively the clinical outcomes and complications of the posterior approach laminoplasty and single-stage anterior approach laminoplasty combined with anterior cervical corpectomy and fusion and anterior cervical discectomy and fusion for treating patients with cervical spondylotic myelopathy coincident multilevel anterior and posterior compression, known as complex cervical spondylotic myelopathy (cCSM) here...

PURPOSE: Lateral mass mini-screws used in plated cervical laminoplasty might penetrate into facet joints. The objective is to observe this complication incidence and to identify the optimal areas for 5- and 7-mm-long mini-screws to implant on lateral mass. METHODS: 47 patients who underwent plated cervical laminoplasty were included. The optimal area for mini-screws implanting was set according to pre-operative 3D CT reconstruction data. Then, each posterior-lateral mass surface was divided into three regions: 7-mm region, 5-mm region, and dangerous area...

A retrospective cohort study. Plated cervical laminoplasty is an increasingly common technique. A unique facet joint disturbance induced by lateral mass miniscrews penetrating articular surface was noticed. Facet joints are important to maintain cervical spine stability and kinetic balance. Whether this facet joint disturbance could affect clinical and radiologic results is still unknown. The objective of this study is to investigate the clinical and radiologic outcomes of patients with facet joints disturbance induced by miniscrews in plated cervical laminoplasty...

BACKGROUND: Piezosurgery is a relatively new osteotomy technique using microvibrations of scalpels at ultrasonic frequencies to perform safe and effective osteotomies without damage to adjacent soft tissue, which is widely used in spinal, oral, and maxillofacial surgery. We hypothesized that such a device could also be useful in cervical laminoplasty. The purpose of this study was to compare the safety and efficacy of a piezosurgery device with those of a highspeed drill in cervical laminoplasty...

PURPOSE: The objective of this study is to compare outcomes of LP and LF. STUDY DESIGN/SETTING: Multicenter international prospective cohort study. PATIENT SAMPLE: A total of 266 surgically treated symptomatic DCM patients undergoing cervical decompression using LP (N=100) or LF (N=166)...

AIM The surgical approaches for spinal tumors, to a great extent, have been developed in accordance with the developments in technology. Today, many surgical techniques are implemented as anterior, anterolateral, posterior, posterolateral and combined approach. Due to its low morbidity, posterior approach is more preferred one. Laminectomy is a widely used technique especially in neoplastic lesions. However, following laminectomy, there are complications like instability, kyphotic deformity and scar formation...

All patients were acute, multi-segment cervical spinal cord compression injury secondary to lower cervical fracture. These patients underwent emergency posterior cervical pedicle screw-rod/plate instrumentation combined with unilateral open-door laminoplasty. Well-placed pedicle screws and good cervical canal dilation were achieved in all patients, as assessed by radiography. Patients were followed up for 6-10 months and showed at least one class improvement in spinal impairment. These cases suggest that simple posterior cervical pedicle screw-rod/plate instrumentation combined with extensive unilateral open-door laminoplasty could repair acute, multi-segment cervical spinal cord compression injury secondary to lower cervical fracture if the cervical sequence is well preserved and does not require restoration...
