What is atlantoaxial rotatory subluxation?
Abstract. Atlantoaxial rotatory subluxation is a rare condition in which patients present with the acute onset of torticollis. Atlantoaxial rotatory subluxation represents a spectrum of disease from muscle spasm to a fixed mechanical block to reduction of the atlantoaxial complex.
What is rotatory subluxation of C1 C2?
Atlanto-axial subluxation is a disorder of C1-C2 causing impairment in rotation of the neck. The anterior facet of C1 is fixed on the facet of C2. It may be associated with dislocation of the lateral mass of C1 on C2.
Is atlantoaxial instability life threatening?
It has been reported that death is common in patients with RA once myelopathy develops in the patients with cervical spine involvement. Thirty-day mortality has been reported to be as high as 13% and 60% at 4 years in patients with advanced cervical disease.
How common is atlantoaxial subluxation?
Posterior atlantoaxial subluxation was less common, occurring in 6.7% of patients, and lateral subluxation occurred in 21% (Weissman et al., 1982).
What does atlas subluxation feel like?
neck pain or a stiff neck. extreme muscle stiffness and restricted shoulder movement. back pain in the lumbar spine as well as hip pain and pelvic misalignment. balance disturbances and dizziness due to functional disorders in the inner ear, nausea or difficulty maintaining concentration.
Can atlas subluxation be fixed?

What is the treatment for subluxation?
Subluxation of the shoulder is treated with rest, ice packs and NSAID’s to reduce the pain and inflammation. You may be referred to physical therapy for shoulder strengthening exercises to help prevent recurrence.
What is traumatic atlantoaxial rotatory subluxation (Aars)?
Background: Traumatic atlantoaxial rotatory subluxation (AARS) is extremely rare in adult versus pediatric populations. Patients usually present with post-traumatic neck pain and torticollis. Surgical management aims at reducing the deformity and stabilizing the spine utilizing external orthotics, and/or internal reduction/fixation.
What is atlanto-axial rotatory fixation?

What are the types of rotatory subluxation?
rotatory subluxation, known as atlantoaxial rotatory fixation (AARF) is characterized into four different types according to the Fielding and Hawkins classification 3 : type I: the atlas is rotated on the odontoid with no anterior displacement type II: the atlas is rotated on one lateral articular process with 3 to 5 mm of anterior displacement
