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...
Rotational Motion about a Fixed Axis01:26

Rotational Motion about a Fixed Axis

A rigid body's rotation around a fixed axis makes every point within it trace a circular path around a specific line or point. The term given to this type of spinning is defined by the angular position, symbolized by the angle θ. This angle is gauged from a static reference line to the revolving object. From this angular position, any variation is referred to as angular displacement, denoted by dθ. The extent of this displacement can be calculated in degrees, radians, or revolutions, where one...
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...
Functional Classification of Joints01:09

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Anatomical Movements00:51

Anatomical Movements

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...
Accessory Structures of the Eye01:17

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Area of Science:

  • Pediatric Orthopedics
  • Rheumatology
  • Neurosurgery

Background:

  • Occipitoatlantoaxial rotatory fixation (OAARF) is a rare condition characterized by fixed rotational subluxation between the occiput, atlas (C1), and axis (C2).
  • Atlantoaxial rotatory fixation (AARF) often precedes OAARF, with untreated AARF potentially leading to compensatory changes and occipitoaxial fixation.
  • Juvenile idiopathic arthritis (JIA) is an autoimmune disease that can affect the cervical spine, increasing the risk of such complex pathologies.

Observation:

  • A case of OAARF is presented in an 8-year-old girl with a history of JIA.
  • Cervical imaging revealed significant rotational abnormalities: occiput to C-2 at 7.63° and C-1 to occiput/C-2 at 65.90°/73.53°, respectively.
  • Initial attempts at closed reduction using halo traction were unsuccessful in correcting the deformity.

Findings:

  • The patient presented with OAARF secondary to JIA, demonstrating severe C1-occiput and C1-C2 rotational malalignment.
  • Imaging confirmed the complex nature of the rotatory fixation, involving multiple cervical segments.
  • Conservative management (halo traction) failed to achieve reduction.

Implications:

  • This case underscores the importance of recognizing OAARF in pediatric patients, particularly those with underlying inflammatory conditions like JIA.
  • Surgical intervention, including open reduction and occipitocervical fixation/fusion, may be necessary for definitive treatment of complex OAARF.
  • Early diagnosis and appropriate management are crucial to prevent long-term sequelae and improve functional outcomes in affected children.
