Late onset neurological deficit is a rare complication of spinal tuberculosis. Reactivation of the disease and compression by internal gibbus are the common causes for late onset neurological deficit. We report a rare cause of late onset paraplegia in a patient with post tubercular kyphotic deformity. The late onset neurological deficit was due to the adjacent segment degeneration proximal to the kyphotic deformity. Posterior hypertrophied ligamentum flavum and anterior disc osteophyte complex caused the cord compression...

Gibbus deformities are characterized by anterior collapse of one or more vertebral bodies resulting in kyphosis. These deformities usually arise from spinal infections, and are traditionally associated with tuberculosis; other pathogens are rarely reported in the literature. In this case report, the authors describe a patient with a sharp, angulated Gibbus deformity presenting with back pain and myelopathy. The patient was placed on antibiotics, underwent T11-T12 corpectomy, placement of an expandable cage, and T8-L3 fusion with improvement of symptoms...

Achieving lumbosacral fusion through spinopelvic fixation is an important and challenging aspect of spinal deformity surgery. Numerous instrumentation techniques are available, with iliac screws and S2-alar-iliac (SRAI) screws being most commonly used today. However, the increasing popularity of minimally invasive sacroiliac (SI) fusion as a common procedure performed for SI joint pain presents a distinct challenge in complex adult deformity cases requiring iliac screw fixation. We report a case of a 71-year-old female with a longstanding history of spinal deformity status-post T11-L5 fusion and a subsequent right-sided SI joint fusion who presented with sagittal imbalance...

Ependymomas are neuroectodermal tumours arising from the ependymal lining of the ventricles and central canal of the spinal cord. Intradural extramedullary (IDEM) ependymomas which are multifocal, and/or anaplastic (WHO grade III) at presentation are exceedingly rare. We present the second case of multifocal anaplastic IDEM ependymoma in the literature. A 47-year old female presented with left gluteal and thigh pain radiating to the groin associated with paraesthesiae. She had a normal neurological examination...

Diffuse idiopathic skeletal hyperostosis (DISH) (Forestier syndrome) is a rheumatologic disease, the etiology of which is not exactly known. It is characterized by spinal osteophyte formations resulting from the ossification of the paravertebral ligaments and muscles. Anterior longitudinal ligament is the usual site of involvement and the frequency of the disease increases after the 5th decade. Lower cervical segments are the most frequently involved regions whereas the upper cervical involvement leading to dysphagia is very rare...

Leiomyosarcoma is a rare type of malignant soft tissue tumor and also one of the most aggressive soft tissue sarcomas. It commonly occurs in uterus, abdominal viscera, retroperitoneal space and soft tissue of the extremities. Primary osseous leiomyosarcoma is a rare condition. Furthermore, primary leiomyosarcoma of the spine is extremely rare. Only few cases have been reported. However, the treatment and outcomes remains controversial. Therefore, the objective of this case report is to illustrate the management of this extremely rare disease by using total en bloc spondylectomy (TES) procedure, which is one of a suitable option for surgical resection of the spinal tumors...

Myxopapillary ependymoma is a rare tumour of the central nervous system (CNS); this subtype of ependymoma occurs most frequently in cauda equina, conus medullaris or filum terminale. The treatment consists of complete removal of the tumour including its capsule when possible since it is usually a solitary lesion. Non-Hodgkin lymphoma of the CNS is found in only 1.3% of cauda equina tumours. We report the case of a 62-year-old man who presented to our institution with progressive weakness of his right lower extremity, with numbness and paresthesia of both feet...

In recent decades cervical arthroplasty, or cervical disc replacement, has been steadily increasing in popularity as a procedure for the treatment of degenerative pathologies of the cervical spine. This is based on an evolving body of literature that documents superior outcomes in cervical disc replacement over fusion, for both single and double level pathologies, in well selected patients. One of the more recent and popular implants currently on the market is the Mobi-C cervical artificial disc (LDR Medical; Troyes, France)...

Spondylolysis is frequently seen in adolescents, typically at the L5 vertebral level. While there may be a congenital predisposition for spondylolysis, it has long been suggested that the defect results from a fatigue or stress fracture of the pars interarticularis. Spondylolisthesis may result from a bilateral spondylolytic defect and is frequently asymptomatic. There is a paucity of literature on infant and toddler spondylolysis, as the focus is primarily on school-aged children, typically those over ten years of age...

Fusion of the lumbosacral spine is a common surgical procedure to address a range of spinal pathologies. Fixation in lumbar fusion has traditionally been performed using pedicle screw (PS) augmentation. However, an alternative method of screw insertion via cortical bone trajectory (CBT) has been advocated as a less invasive approach which improves initial fixation and reduces neurovascular injury. There is a paucity of robust clinical evidence to support these claims, particularly in comparison to traditional pedicle screws...

Osteogenesis imperfecta (OI) is a kind of heritable connective tissue disorder, including blue sclerae, hearing loss, skeletal dysplasia causing bone fragility and deformities. It is typically caused by collagen related gene mutations, which could lead to bone formation abnormalities. Scoliosis is one of the most common and severe spinal phenotype which has been reported in approximately 26-74.5% of all OI patients. Recent breakthroughs have suggested that OI can be divided into more than 16 types based on genetic mutations with different degrees of scoliosis...

There is a rapidly increasing amount of literature outlining the use of three-dimensional (3D) reconstruction and printing technologies in recent years. However, precise instructive articles which describe step-by-step methods of reconstructing 3D images from computed tomography (CT) or magnetic resonance imaging (MRI) remain limited. To address these issues, this article describes a detailed protocol which will allow the reader to easily perform the 3D reconstruction in their future research, to allow investigation of the appropriate surgical anatomy and allow innovative designs of novel screw fixation techniques or pre-operative surgical planning...

Background: Neurogenic intermittent claudication (NIC) is the main symptom of degenerative lumbar spinal stenosis. Percutaneous interspinous process decompression devices (IPDs) have been designed as an alternative therapy to conservative treatment and to open decompressive surgery for patients suffering from NIC. Initial short-term results were encouraging. We present the long-term results of a group of patients that we followed to provide insight on long-term outcomes and effectiveness of this technique compared to other decompression methods...
