Ce travail porte sur une étude rétrospective du vissage antérieur chez 45 patients présentant une fracture de l'odontoïde. La population comportait 36 hommes et 9 femmes dont les fractures étaient du type II dans 35 cas et du type III dans 10 cas. II y avait 34 fractures fraîches et 11 cas anciens. Les complications neurologiques ont été retrouvées chez 16(More)
STUDY DESIGN Prospective 10-year follow-up magnetic resonance imaging (MRI) study of patients who underwent anterior cervical decompression and fusion (ACDF) and healthy control subjects. OBJECTIVE To clarify the incidence of adjacent segment degeneration during 10 years after ACDF. SUMMARY OF BACKGROUND DATA There have been few studies which(More)
There has been no prospective study on age-related changes of the extensor muscles of the cervical spine in healthy subjects. This study was conducted to elucidate any association between the changes in cross-sectional area of the extensor muscles of the cervical spine on MRIs and cervical disc degeneration or the development of clinical symptoms. Sixty-two(More)
OBJECTIVES The purpose of this study was to longitudinally evaluate relationships between the incidence of stiff shoulder and sagittal alignments of the cervical spine, age-related changes on magnetic resonance imaging (MRI) and life styles of the subjects. METHODS The subjects were 69 men and 93 women. The mean follow-up period was 11.3 +/- 0.7 years.(More)
STUDY DESIGN Prospective longitudinal study, mean follow-up period; 11.7 +/- 0.8 years was conducted from 1995 to 2007. OBJECTIVE To clarify normal aging process of cervical spine and correlation between progression of disc degeneration and development of clinical symptoms. SUMMARY OF BACKGROUND DATA Aging of the cervical spine can inevitably occur in(More)
To investigate the frequency of tandem lumbar and cervical intervertebral disc degeneration in asymptomatic subjects. We evaluated magnetic resonance imaging (MRI) results from 94 volunteers (48 men and 46 women; mean age 48 years) for age-related intervertebral disc degeneration in the lumbar and cervical spine. MRI indicated degenerative changes in the(More)
The authors report the case of a 47-year-old woman who harbored a giant cell tumor at the T-5 level. She had undergone curettage of the tumor via a combined anterior and posterior approach at a regional hospital and was later referred to the authors' institution for treatment after the tumor recurred. On examination she exhibited progressive paraparesis and(More)
INTRODUCTION Long-term follow-up studies focusing on the posterior extensor muscles in patients suffering from whiplash injury are scarce. The purpose of this study was to elucidate the changes in the posterior extensor muscles 10 years after whiplash injury. METHODS Twenty-three patients who had suffered from whiplash injury in 1994-1996 and had(More)
To investigate the effects of the menstrual cycle and of exercise intensity on the relationship between finger blood flow (FBF) and esophageal temperature (Tes), we studied four women, aged 20–32 years. Subjects exercised at 40% and 70% $$\dot V_{O_{2_{\max } } } $$ in the semi-supine posture at an ambient temperature of 20‡ C. Resting Tes was higher during(More)
STUDY DESIGN Magnetic resonance imaging (MRI) study on degeneration of the thoracic spine in asymptomatic subjects. OBJECTIVE To investigate the incidence of degenerative MRI findings of the thoracic spine in asymptomatic subjects and to identify factors related to the degeneration of the thoracic discs. SUMMARY OF BACKGROUND DATA Studies on age-related(More)
