Biomechanical

Sawbones® manufactures biomechanical test materials for orthopedic research, medical device testing, and surgical training. These products provide standardized, repeatable alternatives to cadaveric specimens for mechanical testing and evaluation.
Sawbones® biomechanical test materials include cylinders, blocks and sheets, which simulate cancellous and cortical bone properties according to ASTM F1839 standards.
absolute bone models replicate human bone properties, allowing for realistic assessments of implants, fixation techniques, and surgical procedures. These models are designed to support standardized mechanical testing, ensuring repeatable results for regulatory compliance and product validation.
Sawbones® biomechanical products are widely used in orthopedic device testing, finite element analysis, mechanical validation, and surgical education.
