Screws of cortical bone having a trailing end configured to cooperatively engage an implant
First Claim
1. A screw formed of cortical bone for use in the human body with an implant having a screw hole for receiving at least a portion of a screw therethrough, said screw comprising:
- a leading end, a trailing end apposite said leading end, and a shaft therebetween, said shaft having a mid-longitudinal axis and a length;
a thread extending from said shaft along at least a portion of its length, said thread having an outer diameter dimensioned to pass through the screw hole in the implant;
said trailing end being configured to cooperatively engage at least a portion of the screw hole of the implant so as to prevent said screw from linear motion along the mid-longitudinal axis of said shaft in a direction opposite to the direction of insertion when said screw is threaded through the screw hole to attach the implant to a bone portion of the human body; and
said screw being formed substantially of cortical bone of a single cortical thickness.

Abstract
A screw formed of cortical bone for use in the human body with an implant having a screw hole for receiving at least a portion of a screw therethrough, includes a shaft with a thread along at least a portion of its length. The thread has an outer diameter dimensioned to pass through the screw hole in the implant. The trailing end of the screw is configured to cooperatively engage at least a portion of the screw hole of the implant so as to prevent the screw from linear motion along the mid-longitudinal axis of the shaft in a direction opposite to the direction of insertion when the screw is threaded through the screw hole to attach the implant to a bone portion of the human body. The screw is formed substantially of cortical bone of a single cortical thickness.

39. A screw formed of cortical bone for use in the human body with an implant having a screw hole for receiving at least a portion of a screw therethrough, said screw comprising:
-
a leading end, a trailing end opposite said leading end, and a shaft therebetween, said shaft having a mid-longitudinal axis arid a length; a thread extending from said shaft along at least a portion of its length, said thread having an outer diameter dimensioned to pass through the screw hole in the implant; said trailing end being configured to cooperatively engage at least a portion of the screw hole of the implant so as to prevent said screw from linear motion along the mid-longitudinal axis of said shaft in a direction opposite to the direction of insertion when said screw is threaded through the screw hole to attach the implant to a bone portion of the human body; an enlarged portion proximate said trailing end with a dimension transverse to the mid-longitudinal axis of said shaft greater than said outer diameter of said thread, said enlarged portion configured to prevent said trailing end from passing through the screw hole in the implant, said enlarged portion forming a lip; and said screw being formed substantially of cortical bone of a single cortical thickness. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73)
