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.

Rotational subluxation or dislocation of C1 on C2; Can develop from osseous or ligamentous abnormalities resulting from acquired or congenital disorders. As a result of instability, excessive motion and spinal cord compression may occur at the atlantoaxial joint. Epidemiology: Anatomy. 50% rotation of the cervical spine occurs at C1-C2.(Bogduk ...

3 天之前 · The patients present with torticollis where the head is tilted over to one side and rotated to the other side and with slight flexion of the neck. This head position is quite typical and is known as the «cock robin» position (3, 6, 9) – (11), as it resembles the way in which the robin holds its head when listening for a worm (Fig. 2).

Atlantoaxial rotatory subluxation usually presents without neurologic deficits; however, it can be associated with cervical myelopathy in cases with significant compression of the upper cervical spinal cord. Atlantoaxial rotatory subluxation can also presentwithanoccipitalneuralgiaipsilateraltothesideofchin rotation.

2020年9月4日 · Atlantoaxial rotatory subluxation (AARS) is a rare outcome of trauma in adults. We present a case of a 38-year-old female who presented with neck pain and stiffness after a mild trauma. On exam the patient had a "cock-robin" position, comparable to acute torticollis.

2020年11月1日 · Atlantoaxial rotatory subluxation (AARS) is a rare outcome of trauma in adults. We present a case of a 38-year-old female who presented with neck pain and stiffness after a mild trauma. On exam the patient had a “cock-robin” position, comparable to acute torticollis.

Atlan-toaxial rotatory subluxation has been defined as a cause of temporary, self-resolving torticollis in children. However, on occasion it may be a potentially severe rotational deformity of the cervical spine.

One important cause in children is atlantoaxial rotary subluxation. Most children present with pain, torticollis ("cock-robin" position), and diminished range of motion. The onset is spontaneous and usually occurs following minor trauma. A thorough history and physical examination will eliminate the various causes of torticollis.

2007年3月1日 · Objectives: To emphasize the value of computed tomography (CT) scan under general anesthesia in order to prevent misdiagnosing atlantoaxial rotatory fixation-subluxation in children with acute torticollis. Summary of background data: A "cock-robin" posture clinically characterizes painful rotatory fixation of the atlantoaxial joint in children.

2007年3月1日 · A “cock-robin” posture clinically characterizes painful rotatory fixation of the atlantoaxial joint in children. Classically, the observation of persistent displacement of the dens between the lateral mass of the atlas and asymmetry of the atlantoaxial joint on radiography confirmed the diagnosis.
