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:

Surgical ergonomics
Medical device design
Musculoskeletal health in surgery

Background:

Surgeons often adopt awkward postures and neglect body positioning during procedures due to intense concentration.
Prolonged static postures and repetitive movements contribute to surgeon fatigue and potential musculoskeletal disorders.
The need for ergonomic solutions to support surgeons during operative tasks is critical.

Purpose of the Study:

To design and evaluate an ergonomic body support system for surgeons.
To assess the feasibility and effectiveness of the body support during surgical procedures.
To reduce muscle activity and improve surgeon posture during both open and minimally invasive surgery.

Main Methods:

Development of an ergonomic body support system based on ergonomic principles.
Feasibility assessment conducted across seven surgical procedures.
Electromyography (EMG) used to measure muscle activity in back and leg muscles with and without the support.

Main Results:

Six out of seven surgeons found the body support comfortable, safe, and easy to use.
Significant reductions in muscle activity were observed: 44% for erector spinae (chest support) and 74% for gastrocnemius (chest support).
Semistanding support also demonstrated muscle reduction, with 50% for the gastrocnemius muscle.

Conclusions:

The ergonomic body support effectively reduces muscle activity, potentially mitigating long-term physical problems for surgeons.
The device supports natural surgeon posture in various procedures and integrates well with operating room setups.
This innovation offers a practical solution to improve surgeon well-being and operative conditions.
