2025年1月13日 · Diagnosis is made by dynamic CT scan of the cervical spine. Treatment can be a soft collar, halter traction, halo traction, or surgical fusion depending on the chronicity of the condition. Odontoid acts as a pivot point with 1 facet subluxating anteriorly, 1 …

2024年9月24日 · Atlanto-axial rotary fixation is a disorder of C1-C2 causing impairment in neck rotation. 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.

2019年8月25日 · Atlantoaxial rotatory fixation (AARF) is also called atlantoaxial rotatory subluxation or fixed atlantoaxial rotatory subluxation . In AARF, the atlas (C1) is either rotated about the odontoid process or the C1 lateral mass on one side is anteriorly subluxed and rotated relative to the relatively fixed C1-2 facets on the opposite side.

Wortzman and Dewar introduced the term atlantoaxial rotatory fixation in 1968. Rotatory atlantoaxial dislocation occurs usually in otherwise healthy children. Minor or insignificant trauma initiates the process. The torticollis is painless, and often, there are no neurological symptoms.

2017年2月1日 · Atlantoaxial rotatory fixation is a condition in which the first and second vertebrae of the cervical spine become interlocked in a rotated position. This condition can result in serious consequences and thus have a significant impact on patients, especially when diagnosis and treatment are delayed.

Atlantoaxial rotatory fixation (AARF) in adult is a rare disorder that occurs followed by a trauma. The patients were presented with painful torticollis and a typical 'cock robin' position of the head.

Surgical correction of AARD is an appropriate method of treatment after failed non-operative therapy. The technique of surgical reduction and C1–C2 fixation using Harms/Goel technique provides excellent clinical outcomes. In case of traumatic AARD we recommend to consider temporary fixation. 1. Introduction.

Acute Atlantoaxial Rotary Subluxation (AARS) Key Points: Also known as rotatory dislocation, displacement, or fixation Important to differentiate from congenital muscular torticollis Vast majority can be managed with non-operative treatment by observation or traction

Objective: Atlantoaxial rotatory fixation (AARF) remains a recondite entity. Our normative study using CT motion analysis shows that there is a high degree of concordance for rotational behavior of C1 and C2 in children 0 to 18 years.

Atlantoaxial rotatory fixation (AARF) is an acquired fixed rotation abnormality of the C1 vertebra on C2 that impedes turning of the neck and typically manifests with painful torticollis. It is primarily a condition of childhood although adolescent and adult cases are seen [ 1 – 3 ].
