Complete Atlantooccipital Assimilation with Basilar Invagination and Atlantoaxial Subluxation Treated Non-Surgically: A Case Report
نویسندگان
چکیده
Atlantooccipital assimilation is a partial or complete congenital fusion between the atlas and the base of the occiput. Most patients with atlas assimilation are asymptomatic, but some may present with neurological problems such as myelopathy. We present the case of a 37-year-old woman who presented with neck and occipital pain, episodic neck stiffness, and dizziness. Medical imaging revealed complete atlantooccipital assimilation associated with basilar invagination, atlantoaxial subluxation, and predisposing anterior spinal cord compression. The patient was treated non-operatively with medications, cervical interferential therapy, and a rigid cervical orthosis.

Inverted hypertrophy of occipital condyles associated with atlantooccipital fusion and basilar invagination: a case report
Atlantooccipital fusion is complete or partial congenital fusion of the atlas to the base of occiput. Basilar impression may complicate the clinical picture with the reduction of the vertical height of atlas causing odontoid or other bony structures project into foramen magnum and medulla oblongata. This results in narrowing of the foramen magnum and leads to neural compression. Authors present...
متن کاملPreoperative flexion-extension radiographs can't exclude c1/c2 reducibility in c1/c2 subluxation
Background: According to the findings of previous studies, treatment of C1/C2 subluxation especially in congenital anomaly depends on preoperative dynamic radiograph and site (anterior or posterior) of cord compression. Evolution of new technique for instrumentation intraoperative manipulation is more feasible. We present our experience of treating 5 cases “apparently” irreducible atlantoaxial ...

Siemionow and Chou review the surgical management of atlantoaxial instability in the context of Down syndrome, using two interesting illustrative cases with different craniocervical abnormalities (atlantoaxial rotatory subluxation and os odontoideum). Both patients present with significant craniocervical spinal cord compression, and in this context, they highlight the specific case nuances that...

STUDY DESIGN Four patients had C2-3 vertebral fusion and radiologically demonstrated cord compression at C3-4 level related to disc bulge with or without association of osteophytes and C1-2 posterior facetal dislocation. The outcome of treatment by atlantoaxial and subaxial facetal fixation is discussed. PURPOSE The article evaluates the significance of atlantoaxial facetal instability in cas...

OBJECTIVE A novel method of treatment of basilar invagination that involves distraction of the atlantoaxial joint using specially designed spiked spacers is described. Bone graft that is additionally placed within the appropriately prepared atlantoaxial joint and posterior to the arch of atlas and lamina of C2 provides bony fusion. MATERIALS AND METHODS Between December 2002 and April 2007, 1...
