Guillain-Barré syndrome is a rare autoimmune condition characterized by ascending motor weakness of the extremities that can ascend to the diaphragm, causing substantial morbidity and mortality. This case report describes a 57-year-old man who exhibited characteristics of Guillain-Barré syndrome 9 days after undergoing lumbar fusion at L3-S1. The diagnosis was based on the patient's ascending motor weakness and areflexia and was confirmed with electromyography. The patient progressed to respiratory failure, requiring mechanical ventilation...

BACKGROUND: It has been argued that postoperative pain treatment should be "procedure-specific", since different analgesics may have specific effects dependent on the surgical procedure. The aim of the present subgroup analysis was to compare the beneficial and harmful effects of perioperative gabapentin treatment in different surgical procedures. METHODS: Relevant databases were searched for randomized clinical trials (RCTs) comparing gabapentin versus placebo...

INTRODUCTION: Post-operative wound infections after spinal surgery is a very serious problem, leading to a risk of significant morbidity which may even lead to prolonged hospitalization. Various treatment protocols have been recommended for debridement, antibiotic, and soft-tissue management, but with mixed results. However, the risk of morbidity is still high with these treatment options. Vacuum-assisted closure (VAC) system has been gaining popularity recently in the management of subacute, acute, and chronic wounds...

We conducted a retrospective review of 221 patients, who underwent spinal oncologic surgery at a tertiary university hospital between 2005 and 2014; in order to identify and validate factors that influence the impact of preoperative embolization of spinal tumours on outcome measures of blood loss and transfusion requirements in spinal oncologic surgery. We also focused on primary tumour type and type of spinal surgery performed. Patients' electronic and physical records were reviewed to provide demographic data, tumour characteristics, embolization techniques and surgical procedure details...

Although bleeding is a common complication of surgery, routine laboratory tests have been demonstrated to have a low ability to predict perioperative bleeding. Better understanding of hemostatic function during surgery would lead to identification of high-risk patients for bleeding. Here, we aimed to elucidate hemostatic mechanisms to determine perioperative bleeding. We prospectively enrolled 104 patients undergoing cervical spinal surgery without bleeding diathesis. Blood sampling was performed just before the operation...

Injury to the thoracic duct during anterior cervical spine surgery is a rare occurrence. A delayed chyle leak following an elective anterior cervical spinal surgery has not been reported in the literature. We present a report of a 59-year-old female with multiple prior neck surgeries who underwent an anterior cervical corpectomy and fusion (ACCF). The patient developed a delayed thoracic duct injury on postoperative day (POD) one, as no injury was noted intraoperatively. She was managed with conservative care involving a low-fat diet along with octreotide which led to the resolution of her symptoms...

BACKGROUND: Intraoperative neuromonitoring (IONM) has been reported to be sensitive and specific in the detection of neurological injury during spinal surgery. However, utilizing multimodality IONM to predict postoperative neural deficits following cervical laminoplasty remains unclear. OBJECTIVE: The purpose of this study is to clarify the incidence of C5 palsy utilizing multimodality IONM and to compare the accuracy of multimodality IONM to predict postoperative C5 palsy against isolated transcranial motor-evoked potential (MEP)...

BACKGROUND: Older patients, especially those older than 65 years, are accounting for an ever-increasing share of hospital costs, especially surgical procedures. Studies regarding the safety of surgery in these patients have been widespread in the past decade. Despite these efforts, there is a paucity of information regarding the safety of reconstruction following spinal surgery in older patients. METHODS: We conducted a retrospective cohort study of patients undergoing soft-tissue reconstruction of the posterior trunk after oncologic spine surgery...

BACKGROUND CONTEXT: Dramatic increases in the average life expectancy have led to increases in the variety of degenerative changes and deformities observed in the aging spine. The elderly population can present challenges for spine surgeons, not only because of increased comorbidities, but also because of the quality of their bones. Pedicle screws are the implants used most commonly in spinal surgery for fixation, but their efficacy depends directly on bone quality. While PMMA-augmented screws represent an alternative for patients with osteoporotic vertebrae, their use has raised some concerns due to the possible association between cement leakages (CLs) and other morbidities...

OBJECTIVE: Spinal neuronavigation improves accuracy of pedicle screw placement but may increase operative time, and its use in oncological operations remains relatively unstudied. We compared the use of 2-dimensional (2D) fluoroscopy and 3-dimensional (3D) spinal neuronavigation relative to operative time in instrumented oncology procedures. METHODS: Consecutive instrumented oncologic spinal operations for multiple myeloma or metastatic disease performed between 2012 and 2014 were retrospectively reviewed...

Histoplasmosis is an infection caused by a fungus called Histoplasma. Diagnosis of histoplasmosis is based on the culture of biological samples and detection of fungus in tissues. Histoplasmosis can mimic malignant lesions. We report a 65-year-old, immunocompetent, male patient with back pain. We describe the main clinical and radiological characteristics in our patient who had vertebral histoplasmosis that mimicked cancer. A computed tomography scan showed lytic lesions of the right side of T4, T5, and T6 vertebral bodies...

Pedicle screw fixation is the gold standard for the treatment of spinal diseases. However, many studies have reported the issue of loosening pedicle screws after spinal surgery, which is a serious concern. To address this problem, diverse types of pedicle screws have been examined to identify those with good fixation strength and osseointegration in spine bone. The porcine spine is a good alternative for the human spine in the evaluation of pedicle screws due to the anatomical size, mechanical characteristics, and cost...

Sufficient visualisation of the operating field is crucial for success in surgery and is important especially concerning minimal invasive and deep approaches in spine surgery METHODS: The spinal microsurgical approach was imitated using an isolated box that was accessed with different devices. Different light sources and auxiliary devices were analysed aiming to compare them to each other. As light source we used one microscope, one standard operating theatre lamp and one headlamp. The auxiliary devices included different tubes with and without optic light fibre, different retractors and one endoscope RESULTS/CONCLUSION: Hence, we demonstrated that different combinations of light sources and auxiliary devices provide significantly different illumination in the artificial operating field...

BACKGROUND: Lumbar degenerative spondylolisthesis (DS) develops as a result of inflammatory and remodeling processes in facet joints (FJs). Several inflammatory cytokines are involved in the osteoarthritic and remodeling changes that occur and in low-back and/or radicular pain, the most prevalent clinical symptom of disease. This study improves knowledge related to the roles that 27 cytokines, chemokines and growth factors play in the pathophysiology of lumbar DS. MATERIAL AND METHODS: Cytokine levels were examined using capture sandwich immunoassay using the Bio-Plex(®) 200 System and the Bio-PlexTM Human Cytokine Standard 27-Plex, Group I (Bio-Rad, Hercules, California, USA) separately in intervertebral discs (IVDs) and FJ bone tissue...

REVIEW
John F Burke, Sanjay S Dhall
Bone morphogenic protein (BMP) provides excellent enhancement of fusion in many spinal surgeries. BMP should be a cautionary tale about the use of industry-sponsored research, perceived conflicts of interest, and holding the field of spinal surgery to the highest academic scrutiny and ethical standards. In the case of BMP, not having a transparent base of literature as it was approved led to delays in allowing this superior technology to help patients.

Esophageal perforation is a dreaded complication of anterior cervical spinal surgery. A 52-year-old diabetic man had undergone a surgery for a C6-C7 disc prolapse and developed spiking fever with chills and rigor on the 7th postoperative day. No cause could be found out but a CT scan of thorax done in the course of investigations revealed pneumomediastimum. The patient succumbed on the 10th day after surgery. Autopsy revealed the cause of death to be mediastinitis following iatrogenic esophageal perforation...
