OBJECTIVE:  The aim of this study was to retrospectively review the surgical site infection (SSI) rate in dogs undergoing laminectomies without perioperative antibiotics, and compare those data with the expected infection rate for clean surgical wounds in dogs undergoing similar procedures. METHODS:  This was a retrospective single-centre study composed of dogs that underwent hemilaminectomies or laminectomies for thoracolumbar disc herniation or lumbosacral disease during a 2-year period (during 2015 and 2016)...

Spastic diplegic cerebral palsy (CP) is the most common form of CP. A specific goal-oriented approach, tailored to the child, is essential to management in all forms of CP. Selective dorsal rhizotomy (SDR) is a neurosurgical procedure that permanently reduces lower limb spasticity in children with spastic diplegic CP. The current technique is performed through a single level laminectomy at the level of the conus and, with the aid of intraoperative electromyography (EMG), allows selective division of the afferent lumbosacral nerve roots...

Alveolar rhabdomyosarcoma (RMS) is an aggressive soft tissue mass demonstrating rapid growth, dissemination, and leptomeningeal spread. Primary diagnosis is usually established by core biopsy. In rare cases, cytopathologic evaluation is indicated to identify recurrent or metastatic disease. We present a case of a 24-year-old man with a previously diagnosed alveolar RMS of the foot who presented to our institution with back pain. A lumbar puncture was performed and the cerebrospinal fluid (CSF) showed atypical cells demonstrating nuclear enlargement, eccentricity, binucleation, and frequent karyorrhexis...

Lumbar laminectomy often results in failed back surgery syndrome. Most scholars support the three-dimensional theory of adhesion: Fibrosis surrounding the epidural tissues is based on the injured sacrospinalis behind, fibrous rings and posterior longitudinal ligaments. Approaches including using the minimally invasive technique, drugs, biomaterial and nonbiomaterial barriers to prevent the postoperative epidural adhesion were intensively investigated. Nevertheless, the results are far from satisfactory. Our review is based on various implant biomaterials that are used in clinical applications or are under study...

We report a rare case of familial inherited abnormal bone hyperplasia and ossification of the yellow ligament complicated by spinal stenosis. Complete reconstruction of stability and spinal cord decompression were achieved by posterior total laminectomy, fusion and internal fixation. We cannot clearly describe the inheritance characteristics of the disease. Although the risk of surgical treatment is high, it is still necessary to perform surgery, and the effect of the operation is substantial.

Ossification of the posterior longitudinal ligament (OPLL) in the cervical spine and related neurological complications are not uncommon in East Asian countries. The estimated prevalence of cervical OPLL-related hospitalization is 7.7 per 100,000 person-years in Taiwan, and higher incidence rates have been observed in elderly and male patients. Although cervical OPLL is frequently insidious, it can eventually cause myelopathy and predispose patients to spinal cord injury (SCI). There are multiple options for managing cervical OPLL, ranging from observation to many kinds of surgical procedures, including posterior laminoplasty, laminectomy with or without fusion, anterior corpectomy with or without instrumentation, and circumferential decompression and fusion...

A 16-year-old boy with Chiari 1 malformation presented for an elective suboccipital craniectomy and C1 laminectomy. His intraoperative course was uneventful. At the conclusion of the procedure, he met extubation criteria and followed commands. After extubation, he developed progressive upper airway obstruction and became obtunded. He was reintubated via videolaryngoscopy, which showed edema not only to the tongue, but also to the posterior pharynx and blisters over the vocal folds and epiglottis. The patient was transferred to the pediatric intensive care unit intubated and sedated...

Background: Laminoplasty is an established alternative to laminectomy for posterior cervical decompression in spondylotic myelopathy. However, standard laminoplasty requires internal fixation, which is often not obtainable in developing countries. We present our experience with a technique of noninstrumented (floating) laminoplasty developed to avoid the need to anchor the laminoplasty to the anterior elements. Methods: We have used floating laminoplasty (FL) for posterior cervical decompression in patients with cervical spondylosis since 2004 and report the technique and our experience with it between 2009 and 2014 when C-arm and magnetic resonance imaging became available in our unit...

Gout is a common metabolic disorder, typically diagnosed in peripheral joints. Tophaceous deposits in lumbar spine are a very rare condition with very few cases reported in literature. The following is a case report of a 52-year-old patient with low back pain, left leg pain, and numbness. Serum uric acid level was in normal range. magnetic resonance imaging, bone scan, and gallium-67 images suggested an inflammatory-infectious process focus at L4. After a decompressive laminectomy at L4-L5 level, histological examination showed a chalky material with extensive deposition of amorphous gouty material surrounded by macrophages and foreign-body giant cells (tophaceous deposits)...

BACKGROUND: Meningioma is a common slow growing spinal tumour with a predilection for intradural occurrence. Patients usually present with pain followed by ataxia and sensory and sphincter problems. The gold standard treatment in these cases is gross total microsurgical resection under general anaesthesia. However, there exist high anaesthetic risk patients unsuitable for general anaesthesia. Performing spinal surgeries under local anaesthesia and sedation has been reported albeit rarely for mostly minimally invasive procedures but not for open intradural pathologies...

Spinopelvic injuries result from high energy trauma with overloading through the sacrum. These lesions can accomplish either bone fractures, ligament injuries or, most commonly, both. They may be accompanied with other associated life threatening injuries and cause biomechanical instability with potential fracture non-union, mal-union and subsequent lifetime pain and disability. Surgical stabilization of spinopelvic injuries requires planning in order to apply the appropriate osteosynthesis principles (compression; neutralization; buttressing and tension band)...

OBJECTIVE: Space-occupying spinal metastases (SM), commonly diagnosed because of acute neurological deterioration, consequently lead to immediate decompression with tumor removal or debulking. In this study, we analyzed a series of patients with surgically treated spinal metastases and explicitly sought to determine individual predictors of functional outcome. PATIENTS AND METHODS: 94 patients (26 women, 68 men; mean age 64.0 years) with spinal metastases, who had been surgically treated at our department, were included retrospectively...

BACKGROUND: TGF-β has been described as a mediator of fibrosis and scarring. Several studies achieved reduction in experimental scarring through the inhibition of TGF-β. Fibroblasts have been defined as the cell population originating fibrosis, blocking fibroblast invasion may impair epidural fibrosis appearance. For this purpose, biocompatible materials used as mechanical barriers and a TGF-β inhibitor peptide were evaluated in the reduction of epidural fibrosis. METHODS: A L6 laminectomy was performed in 40 New Zealand white rabbits...

RATIONALE: Epidural hematomas can develop following intrathecal puncture, spinal vascular malformation, or spontaneous hemorrhage. Prompt recognition of symptoms and referral to neurosurgical services are crucial for recovery. We report a rare case of delayed removal of an epidural hematoma that resulted in good patient outcomes. PATIENT CONCERNS: A 69-year-old woman weighing 58 kg presented with back pain that had persisted for 12 years. Her medical history was notable for hypertension...

BACKGROUND: Degenerative alterations of the cervical spine often entail disc herniations and stenoses of the spinal canal and/or neural foramen. Mediolateral or lateral compression of nerve roots causes cervical radiculopathy, which is an indication for surgery in cases of significant motor deficits or refractory pain. Median canal encroachment may result in compression of the spinal cord and cervical myelopathy. Its natural history is typically characterized by episodic deterioration, so that surgical decompression is indicated in cases of clear myelopathic signs...

Introduction: Spinal subdural hematomas are rare, disabling hemorrhages. Ankylosing spondylitis (AS) is a relatively common inflammatory condition of the spine that can progress to a fragile, unstable fusion vulnerable to fracture. While spinal epidural hematomas have been described, subdural hematomas to date have not been reported in AS. In this report, we describe the unique case of a patient on warfarin with AS who developed a spinal subdural hematoma and fracture in the absence of trauma...

Background: Previous studies on the correlation between cervical sagittal balance with improvement in quality of life showed significant results only for parameters of the anterior translation of the cervical spine (such as C2-C7 SVA). Objective: We test whether a new parameter, cervicothoracic lordosis , can predict clinical success in this type of surgery. Methods: The focused group involved patients who underwent surgical treatment of cervical degenerative disk disease by the posterior approach, due to myelopathy, radiculopathy or a combination of both...
