چکیده
BackgroundOssification of the posterior atlantoaxial membrane (PAAM) is a rare cause spinal cord compression.Case presentationA 46-year-old woman with rheumatoid arthritis (RA) and 2-year history slowly progressive gait disturbance underwent surgery for right knee stiffness lower limb mild weakness. A neurologic examination revealed brisk deep tendon reflexes (DTR) spasticity in her four limbs. computed tomography (CT) scan stenosis caused by ossification PAAM, compression. The patient's limbs weakness walking capability were ameliorated post-surgery.ConclusionsAlthough exact mechanism PAAM remains unclear, chronic mechanical stress as well persistent instability may promote development ossification.

Ossification of the posterior atlantoaxial membrane associated with an os odontoideum: a case report.
We report a case of ossification of the posterior atlantoaxial membrane associated with an os odontoideum in a 46-year-old woman. She developed myelopathy following a minor motor vehicle accident. The patient underwent posterior atlantoaxial arthrodesis and resection of the ossified lesion and recovered uneventfully. Long-standing atlantoaxial instability might have played a role in ectopic oss...

متن کاملCongenital lumbar spinal stenosis with ossification of the ligamentum flavum in achondroplasia: a case report
INTRODUCTION Achondroplasia is a genetic disorder of bone growth. Congenital spinal stenosis is a well-known complication of this disease, but, to the best of our knowledge, no cases involving combined stenosis with congenital lumbar spinal stenosis and ossification of the ligamentum flavum in achondroplasia have been reported previously. In this report, we describe a case of a patient with con...
متن کاملPosterior spinal tuberculosis: a case report.
Posterior spinal tuberculosis (PST) is a form of skeletal tuberculosis that selectively involves the vertebral arch. Since typical tuberculous spondylitis spreads to involve the adjacent disk spaces while PST does not, the radiographic appearance of PST often mimics skeletal neoplasm. Although PST has been reported in developing countries, particularly India and Pakistan, and among nonwhite imm...
