Anatomical Positions

Anatomical Positions

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Area of Science:

Craniomaxillofacial surgery
Surgical navigation
Orthognathic surgery

Background:

Navigated craniomaxillofacial surgery requires stable fixation of repositioned bone segments.
Current methods may lack precision in maintaining desired fragment positions during complex procedures.

Observation:

A case study demonstrated the use of a miniature external mandibular distractor for bilateral lateral orbital rim advancement.
The distractor allowed incremental, multi-directional adjustments of bone segments under intraoperative navigation.

Findings:

The miniature external distractor provides incremental control over bone segment positioning.
Its small size and adaptability facilitate precise manipulation during navigated procedures.
This method ensures reliable fixation for osteosynthesis in complex craniomaxillofacial reconstructions.

Implications:

Miniature external distractors can enhance the accuracy and reliability of navigated craniomaxillofacial surgery.
This technique may improve outcomes in reconstructive and aesthetic procedures involving bone segment repositioning.
Further research could explore broader applications in various craniofacial surgical contexts.
