Our goal was to analyze the anatomical parameters of the lumbar spine spinous process for an interspinous stabilization device designed for the Chinese population and to offer an anatomical basis for its clinical application. The posterior lumbar spines (T12-S1) of 52 adult cadavers were used for measuring the following: distance between two adjacent spinous processes (DB), distance across two ...
This article presents an unusual case of arachnoiditis ossificans after spinal surgery. A case of arachnoiditis ossificans secondary to lumbar fixation and decompression surgery for the treatment of multilevel lumbar fractures is reported and the relevant literature is reviewed. A 29-year-old man who previously underwent posterior pedicle screw fixation and fusion for multiple lumbar spine frac...
OBJECTIVE To report a rare case of lumbar vertebral subluxation associated with spontaneous reduction in an adolescent treated conservatively. CLINICAL PRESENTATION AND INTERVENTION A 14-year-old male victim of a snowboard accident, which caused a lumbar spinal injury, was referred to the emergency room with significant lumbar pain. Neurologic examination was normal. Radiographic assessment a...
objective: the aim of this cross-sectional analytic study was to evaluate the diagnostic efficacy of panoramic-based indices of the mandible (mental index-mi, mandibular cortical index-mci and panoramic mandibular index-pmi) and to determine their correlation with bone mineral density (bmd) of the femoral neck and lumbar vertebrae (l2-l4) in order to assess the possibility of using these parame...
a 25-year old man presented with chronic low back pain for about 5 years due to mild congenital lumbar kyphosis (l1-l3 25° with congenital posterior wedge vertebra l2). preoperative neurologic examination was normal. after posterior spinal fusion and instrumentation with moderate curve correction, the patient gradually developed the symptoms and signs of cauda equina syndrome due to intraoperat...
OBJECT Minimally invasive anterolateral approaches to the lumbar spine are options for the treatment of a number of adult degenerative spinal disorders. Nerve injuries during these surgeries, although rare, can be devastating complications. With an increasing number of spine surgeons utilizing minimal access retroperitoneal surgery to treat lumbar problems, the frequency of complications associ...
background & importance: cavernous angiomas are typically superficial lesionscreated by anomalous vessels and found in the skin or mucosa, but intradural locations are rare especially in the spine. we report a case of the spinal intradural cavernous angiomas of the lumbar spine. case presentation: a 53-year-old man presented with a 6-month history of low back pain and bilateral radicular pain. ...
Background Few studies in the literature discuss operative positioning for lumbar surgery precipitating acute cauda equina syndromes (CES). Case Description A 56-year-old male with a large L2-3-disc herniation was placed prone on a Jackson table. He immediately lost all motor and sensory evoked potentials. Signals returned to the baseline when surgery was aborted, and he was returned to the s...
Spinal schwannomas are one of the most common intradural extramedullary spinal tumors. However, a string of bead-like intradural extramedullary schwannoma is highly uncommon. In the paper we present a case of a long-segment string of bead-like intradural extramedullary schwannoma of cauda equina from L2 to S2.The patient had been suffering progressive low back pain and sciatica with progressive...
STUDY DESIGN Retrospective study. PURPOSE To review the results and proximal adjacent problems of long fusion (more than 4 levels) according to the level of proximal fusion (L2~T9) in adult lumbar deformity using pedicle screw fixation. OVERVIEW OF LITERATURE There are few written reports concerning proximal adjacent segmental failure according to the level of proximal fusion in adult lumba...
