Female R.A with UMN the investigate required to evaluate is
|A||Spine lateral view flexion and extension views|
|B||Open mouth view|
Spine lateral view flexion and extension views
a. Atlantoaxial instability (AAI) is characterized by excessive movement at the junction between the atlas (C1) and axis (C2) as a result of either a bony or ligamentous abnormality. Neurologic symptoms occur when the spinal cord is involved and is uppermotor neuron signs in limbs.
b. The causes of AAI are varied. AAI sometimes results from trauma. Other cases occur secondary to an upper respiratory infection or infection following head and neck surgery. Another cause is rheumatoid arthritis (RA), with its predilection for the upper cervical spine and this causes. In addition, congenital anomalies, syndromes, or metabolic diseases can increase the risk of AAI.
The assessment involves flexion extension lateral view of cervical spine
a. Can assess this instability.
b. Open mouth view is for atlanto axial area specially dens but will not demonstrate instability.
c. Swimmers view is for cervicothoracic junction assessment.
d. Brodens view is for subtalarjoint
