Articulations of the Vertebral Column01:28

Articulations of the Vertebral Column

In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
Equilibrium and Balance01:15

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
Muscles that Move the Head01:19

Muscles that Move the Head

The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
Dysrhythmias II: Classification of Tachyarrhythmias01:28

Dysrhythmias II: Classification of Tachyarrhythmias

Tachyarrhythmias are a type of dysrhythmia where the heart rate exceeds 100 beats per minute. Here are some common types of tachyarrhythmias:Sinus TachycardiaSinus tachycardia originates from increased impulses from the sinus node, leading to an elevated heart rate. It is often triggered by stress, fever, or exercise.Patients may experience palpitations, a sensation of a racing heart, dizziness, and chest discomfort.Causes and Risk Factors: Common causes include physical exertion, emotional...

Summary

Atlantoaxial dislocation (AAD) can cause neck pain and neurological issues. This case highlights dizziness as a rare but important symptom of AAD, emphasizing the need for cervical instability assessment.

Area of Science:

  • Neurology
  • Orthopedics
  • Radiology

Background:

  • Atlantoaxial dislocation (AAD) or subluxation (AAS) involves instability between the atlas (C1) and axis (C2) vertebrae.
  • While neck pain and torticollis are common, dizziness is a rarely reported symptom of AAD/AAS.

Purpose of the Study:

  • To report a rare case of AAD presenting primarily with dizziness in an adolescent.
  • To underscore the importance of considering cervical instability in the differential diagnosis of dizziness.

Main Methods:

  • A case report of an adolescent female presenting with dizziness, neck pain, and torticollis.
  • Diagnostic workup included neurological examination and cervical spine imaging (CT angiography).
  • Treatment involved conservative management followed by surgical reduction and C1-C2 fixation and fusion.

Main Results:

  • The patient presented with non-spinning dizziness, neck pain, and torticollis after prolonged head movement.
  • Cervical imaging confirmed atlantoaxial rotatory dislocation and fixation.
  • Surgical intervention led to complete resolution of dizziness and torticollis without complications.

Conclusions:

  • Dizziness can be a primary presenting symptom of atlantoaxial dislocation.
  • Cervical instability should be included in the differential diagnosis for patients experiencing dizziness.
  • Prompt diagnosis and appropriate management of AAD are crucial for symptom resolution.
