Neurologic complications resulting from surgery for 384 cases of cervical myelopathy (cervical soft disc herniation, spondylosis, ossification of the posterior longitudinal ligament) were reviewed. Surgical procedures performed included 134 anterior interbody fusions (Cloward or Robinson-Smith technique), 70 subtotal corpectomies with strut bone graft, 85(More)
STUDY DESIGN A literature review was conducted to integrate and compile available reports on postoperative C5 palsy. OBJECTIVES To review the clinical features, possible pathogenesis, and procedures for treatment and prevention of postoperative C5 palsy as a complication of surgery for cervical compression myelopathy. SUMMARY OF BACKGROUND DATA Although(More)
We present two cases of skeletal metastases from myxoid liposarcoma, occurring several years after treatment of the primary tumors in the lower limb. The present two case reports have unusual radiological features only detectable by MR imaging and not by plain radiographs or bone scans. From the present two cases, we found that a negative plain radiograph(More)
We evaluated 30 patients with cervical myelopathy before and after decompressive surgery and compared them with 42 healthy controls. All were asked to grip and release their fingers as rapidly as possible for 15 seconds. Films recorded with a digital camera were divided into three files of five seconds each. Three doctors independently counted the number of(More)
STUDY DESIGN Three-dimensional intervertebral motions of the subaxial cervical spine during head rotation were investigated in healthy volunteers using three-dimensional magnetic resonance imaging (MRI). OBJECTIVES To document intervertebral coupled motions of the subaxial cervical spine during rotation. SUMMARY OF BACKGROUND DATA In vivo(More)
In order to clarify the risk of cancer development in patients with rheumatoid arthritis (RA), the incidence of malignant tumors during a follow-up period was investigated in RA patients at the Center for Adult Diseases, Osaka, Japan. Six hundred and fifty-five eligible rheumatoid patients (131 males, 524 females) who were admitted to our institute between(More)
STUDY DESIGN A retrospective case-control study. OBJECTIVE To clarify associations between both lamina horizontalization and facet tropism and adjacent segment degeneration (ASD). SUMMARY OF BACKGROUND DATA We have previously reported coexistence of lamina horizontalization and facet tropism adjacent to the cranial fusion segment as risk factors for(More)
A comparative study of surgical results was used to determine the treatment of choice for multisegmental cervical spondylotic myelopathy. Forty-one patients who received subtotal corpectomy and strut grafting (SCS) and forty-two undergoing laminoplasty were followed up for at least 2 years after surgery. Regarding factors known to affect surgical prognosis(More)
STUDY DESIGN The authors retrospectively analyzed the prevalence and features of neck and shoulder pain (axial symptoms) after anterior interbody fusion and laminoplasty in patients with cervical spondylotic myelopathy. OBJECTIVES To reveal the difference in prevalence of postoperative axial symptoms between anterior interbody fusion and laminoplasty and(More)
STUDY DESIGN A retrospective study was conducted. OBJECTIVE To compare the long-term outcomes after laminoplasty and anterior spinal fusion (ASF) for cervical myelopathy secondary to disc herniation. SUMMARY OF BACKGROUND DATA There have been no reports of long-term comparative studies of laminoplasty and ASF for cervical myelopathy due to disc(More)
