Chain saw injuries: review of 330 cases

Area of Science:

• Traumatology
• Public Health
• Occupational Safety

Background:

• Chain saw injuries represent a significant cause of trauma, particularly in occupational settings.
• Understanding injury patterns is crucial for developing effective prevention strategies.
• Previous research indicates power tool injuries share common characteristics.

Purpose of the Study:

• To identify typical patterns in chain saw injuries.
• To determine the most frequently injured body parts and common causes.
• To inform prevention strategies for reducing chain saw-related trauma.

Main Methods:

• Retrospective review of 330 chain saw injury patients.
• Data collected from emergency clinic admissions between 1972 and 1979.
• Analysis of injury characteristics, including location, cause, and severity.

Main Results:

• The majority of injuries occurred on the left side of the body.
• Common causes included saw kickback (upward or downward).
• Frequently injured areas were the face (excluding eyes), neck, hands, and feet. Forty-eight patients required hospitalization for severe injuries, and one patient died on arrival.

Conclusions:

• Chain saw injuries exhibit predictable patterns, similar to other power tool injuries.
• Many severe and costly injuries could be prevented through proper equipment, training, and adherence to safety protocols.
• Technological advancements like automatic motor brakes and legislative measures are being implemented to enhance safety.
