HOL tests and analyzes medical devices for use in total joint replacement, spine, fracture repair and osteoarthritis. Studies are tailored according to the need, for example, data generation for peer-reviewed publications, FDA regulatory submission, or blinded testing.

HOL conducts in vitro and animal testing based on ISO 10993 guidelines. Our facilities comply with the Office of Laboratory Animal Welfare (OLAW) National Institutes of Health standards. Protocols are submitted and reviewed by Institutional Animal Care and Use Committee (IACUCs) to ensure compliance with federal regulations.

HOL’s cadaver lab is available for use to test devices in both early and late stages of development.

Animal models are conducted for the following applications:
