Study Design. A retrospective study. Objective. To determine the risk factors for sacroiliac joint pain (SIJP) after lumbar or lumbosacral fusion. Summary of Background Data. Recently, has gained increased attention as a source We examined related to development SIJP Methods. In total, 262 patients who underwent fusion from June 2006 2009 were included in this All did not show clinically preoperative screening period considered. Of these patients, 28 newly developed SIJP. investigated...
Study Design. A retrospective study. Objective. To examine the postoperative incidence of sacroiliac joint pain (SIJP) at lower fusion level following multisegment fusion. Summary Background Data. Recently, is being increasingly performed. While proximal junctional kyphosis (PJK) commonly develops fusion, SIJP also occurs this surgery. In surgery for adult spinal deformity, fixation often extended to pelvis include joint. Therefore, question whether in such cases interesting. Here, we...
Summary Background A small GTPase, Rho, and its target molecule, Rho‐kinase, play an important role in the cell functions, including contractility, chemotaxis, adhesion, migration. It is generally considered that eosinophilic inflammation hyper‐reactivity to methacholine airways are fundamental pathophysiology of bronchial asthma. Objective This study was designed determine whether Rho/Rho‐kinase pathways involved eosinophil recruitment airway hyper‐reactivity. We investigated inhibitory...
The records of 14 patients with malignant or aggressive benign vertebral tumors the thoracolumbar spine who underwent total spondylectomy (TS) were evaluated retrospectively. Total was performed by bisecting affected vertebra through pedicle using fine threadwire saws and removing en bloc posterior procedure alone one-stage anteroposterior combined procedure. Remarkable pain relief ambulation after surgery achieved in all patients. No serious complications occurred. Nerve roots sacrificed...
Study Design. A case report of nontraumatic acute complete paraplegia resulting from cervical disc herniation. Objectives. To describe a rare enlargement herniated in the spine and to outline appropriate management patient with severe spinal cord compression secondary herniation developmental canal stenosis. Summary Background Data. Acute progression myelopathy into is rare. There are only four reported cases No other has described magnetic resonance imaging findings noted before after onset...
A retrospective clinical study.To assess the efficacy of a new spinal reconstruction technique (posterior-approach vertebral replacement with rectangular parallelepiped cages: PAVREC) for treatment osteoporotic late collapse neurological deficits.Poor bone quality and medically complicated situations obfuscate precise paraplegia caused by collapse. Recently, posterior-approach corpectomy cylindrical cage have been proposed. However, postoperative subsidence kyphosis progression frequently...
Introduction: Sacroiliac joint pain (SIJP) after lumbar fusion surgery has recently gained attention as a source of low back fusion. There are two risk factors for postoperative SIJP, i.e., involving the sacrum and multiple-segment In this study, we examined whether SIJP could occur more frequently in patients with (multiple-segment to sacrum). Further, (≥3) fusion, focusing on difference between floating (non-fused sacrum) fixed (fused
Crystal-induced arthritis of the lateral atlantoaxial joint may be intimately involved in acute neck pain elderly. Patients typically have a good prognosis, and symptoms usually subside within few weeks. On other hand, septic requires early diagnosis antibiotic treatment. Diagnostic delay is risk factor for an unfavorable outcome vertebral osteomyelitis. Even though very rare clinical entity, it important to differentiate from crystal-induced arthritis.A 53-year-old Japanese man presented...
Introduction. An arachnoid web (AW) is a relatively rare disease and shows clinical symptoms radiological findings similar to those of an cyst (AC) or spinal cord herniation (SCH). Since the operative procedures for AW are generally different from intrathecal disorders, correct preoperative differential diagnosis important. The purposes this study were report usefulness magnetic resonance imaging (MRI) computed tomography (CT) myelography diagnosing show histological results. Case...
A retrospective study.To examine the efficacy and safety for a posterior-approach circumferential decompression shortening reconstruction with titanium mesh cage lumbar burst fractures.Surgical severely unstable fractures requires an anterior or combined anteroposterior approach. Furthermore, instrumentation lower is restricted through presence of major vessels.Three patients L1 fracture, one L3 three L4 (5 men, 2 women; mean age, 65.0 years) who underwent posterior approach alone 4-year...
Calcification of the yellow ligament sometimes compresses spinal cord and can induce myelopathy. Usually, calcification does not acute neck pain. We report a case patient with pain caused by calcium pyrophosphate dihydrate in calcified cervical ligament.A 70-year-old Japanese woman presented She had moderately high fever (37.5 °C), her was so severe that she could move any direction. Computed tomography showed high-density area between C5 C6 laminae suspicious for ligament. Magnetic...
Gas gangrene is most often caused by Clostridium perfringens infection. a medical emergency that develops suddenly. The mortality rate higher with trunk involvement than of the extremities, which carries better prognosis. With respect to vertebral involvement, there are few reports in literature. purpose this paper report very rare case osteomyelitis gas gangrene. A 78-year-old Japanese woman diabetes mellitus was admitted our hospital chief complaints back pain, dysuria, and complete...
Prospective study.
Gossypiboma is rare and mostly asymptomatic in chronic cases. It can be confused with other soft tissue masses. Our patient was an 87-year-old Japanese man a history of surgery for lumbar lesion causing canal stenosis 19 years earlier. Computed tomography showed mass osteolysis periosteal thickening the vertebral lamina. On magnetic resonance imaging, heterogeneous signal intensity on T2-weighted suggesting malignancy. At time biopsy, small pieces retained surgical sponge were collected....
Sacral stress fracture is an uncommon cause of back pain. The majority previously reported cases have been in runners. purpose this case report was to describe a sacral amateur rugby player. A healthy 18-year-old Japanese boy who player presented with 3-week history lumbago. Sagittal and axial magnetic resonance imaging failed reveal any reason for lumbago his lumbar region. On second presentation, 4 weeks later, so severe that he could not walk without cane. revealed bone marrow edema...

Remote cerebellar hemorrhage is a rare complication of spinal surgery. Although loss cerebrospinal fluid seems to play an important role in the pathogenesis this complication, detailed mechanism remote after surgery remains unclear. We report case patient with following thoracic intradural extramedullary tumor and discuss entity reference literature.A 57-year-old Japanese woman presented our hospital back pain, dysuria, numbness both legs. A neurological examination was performed, imaging...
