STUDY DESIGN Results of the posterior long fusion performed for the progressive cervical lesions of rheumatoid arthritis were compared with the outcomes of those who did not undergo surgical treatment. OBJECTIVE To provide a clue as to whether posterior long fusion improves or maintains the impaired daily life activity of the patients with rheumatoid(More)
STUDY DESIGN Immunohistologic staining of human intervertebral discs collected at the time of surgery (100 intervertebral discs from 80 patients) and 10 discs collected from 7 cadavers within 12 hours of death was performed using antimatrix metalloproteinase-3 monoclonal antibody and antitissue inhibitor of metalloproteinase-1 monoclonal antibody.

We present a case of traumatic L4-5 bilateral facet dislocation, without neurological deficit, in a 32-year-old female patient, as an unusual seatbelt injury caused by positioning the shoulder harness improperly under her armpit. Open reduction, posterior interbody fusion, and posterior segmental instrumentation were carried out. The aim of this report is(More)
The aim of this study was to determine whether postoperative malalignment of the cervical spine after anterior interbody fusion surgery promotes degenerative changes in the neighboring intervertebral discs. Forty-two patients who underwent anterior interbody fusion surgery for cervical spondylosis and disc herniation (34 men, 8 women) were followed for an(More)
The aim of this study was to show whether anterior cervical plate stabilization is able to maintain cervical lordosis or not when used for cervical degenerative disease. Thirty cases that underwent anterior fusion at multiple levels without cervical plating before 1986 were compared with 44 cases treated with cervical plating since 1986. Changes in the(More)
A novel cytotoxin (intermedilysin) specific for human cells was identified as a cytolytic factor of Streptococcus intermedius UNS46 isolated from a human liver abscess. Intermedilysin caused human cell death with membrane blebs. Intermedilysin was purified from UNS46 culture medium by means of gel filtration and hydrophobic chromatography. The purified(More)
We investigated 30 patients with multilevel cervical spondylotic myelopathy (22 males and 8 females) treated by "French window" laminoplasties from 1979 to 1988. Patients averaged 62.6 years of age, and were followed an average of 5 years and 2 months. The average preoperative and postoperative Japanese Orthopaedic Association (JOA) scores were assessed,(More)
A retrospective analysis of long-term follow-up results more than 10 years after a standard nucleotomy for lumbar disc herniation with the Love method was done to determine the effectiveness of this procedure. Nucleotomy according to Love was the standard treatment for lumbar disc herniation before the various minimally invasive alternatives were recently(More)
It is well known that a narrow spinal canal is frequently associated with cervical spondylotic myelopathy. However, few investigators have studied the relationship between the size of the cervical spinal canal and that of the cervical spinal cord. Moreover, no studies mention the correlation between the size of the vertebral body and that of the spinal(More)
