  • Soft tissue retainer for use with bone implants, especially bone staples
    Patent number: 4278091
    Abstract: A novel combination of a bone implant, e.g. a bone staple, and a tissue retention element in sliding relation therewith is disclosed. The tissue retention element is provided with a multiplicity of teeth capable of piercing and holding in place adjacent soft tissue when the implant is driven into the bone structure of a patient. Since the tissue retention element is separable from the implant, the same element can be used in combination with different bone implants.
