BACKGROUND To evaluate the effect of spondylolisthesis on lumbar lordosis on the OSI (Jackson; Orthopaedic Systems Inc.) frame. Restoration of lumbar lordosis is important for maintaining sagittal balance. Physiologic lumbar lordosis has to be gained by intraoperative prone positioning with a hip extension and posterior instrumentation technique. There are some debates about changing lumbar lor...

We report two rare cases of spinal intraosseous schwannoma (SIS) with sustained myelopathy symptoms and provide an updated review regarding SIS in the literature. A 71-year-old man experienced right lumbocrural pain and gait disturbance accompanied with paresthesia and right leg weakness. Imaging examinations revealed a mass with lesions in L4 vertebral body causing bone destruction and spinal ...

Here we report a case of late-onset non-dysraphic intradural spinal cord lipoma and provide a brief review of the literature. A 67-year-old man was referred to our department with a 6-month history of progressive gait ataxia. He had spastic paraparesis with left iliopsoas muscle weakness and hypoesthesia predominantly in the left leg. Magnetic resonance imaging (MRI) revealed an intradural extr...

Traumatic injury to an adjacent segment of a previously fused spine is a rare complication of scoliosis surgery. The adjacent spinal segments may be more vulnerable to traumatic fracture or dislocation due to increased strain. We present a patient with prior C2 to sacrum fusion who suffered a C2 fracture/dislocation after falling. A 52-year-old female with a previous C2 to the sacrum fusion for...

Introduction: Spinal tuberculosis is the most common form of skeletal tuberculosis with the dorsolubar region being the most commonly affected region. The most dreaded complication of spinal tuberculosis is tubercular paraplegia seen in around 40% of the cases. There has been controversy regarding the surgical treatment of the disease and also the approach to be used and the use of implants. In...

Spinal tuberculous abscesses usually respond to anti-tuberculous drugs. The purpose of this study was to evaluate the results of surgical drainage after failure of first-line anti-tuberculous drugs. Patients with spinal instability or vertebral collapse were excluded from the study. The authors retrospectively reviewed 11 patients. The operation was successful in all patients. Anterior/posterio...

BACKGROUND Diastematomyelia is a rare congenital malformation of the spinal cord, which belongs to the group of occult spinal dysraphisms. This disorder consists in the separation of the spinal cord into two parts in the sagittal plane (hemicords). Diastematomyelia may coexist with other spinal dysraphisms, such as myelomeningocele, meningocele, spinal lipoma, neuroenteric cysts or dermal sinus...
