Abstract
Bioresorbable pin systems useful for the reduction of bone fragments and for fixing bioresorbable membranes to a bone are provided, particularly pins having a detachable handle and a pre-fabricated hole in the handle through which a tether may be threaded to facilitate removal of the handle once it has been detached from the pin.
Claims12
A bioresorbable bone pin system for insertion into an aperture in a bone to fix a bioresorbable membrane or bony fragment to the bone, comprising:
- a pin portion having a shank and a head larger in diameter than said shank;
- and
- a handle portion coupled to said head and capable of being severed proximal to said head;
- wherein said handle portion includes an elongated shaft portion proximal to said head and a gripping portion distal from said head, said gripping portion being sufficiently large to be manually grasped by a user to insert the pin shank into the aperture in the bone, and said shaft portion being smaller in diameter than said gripping portion;
- and wherein said handle portion further includes a hole through which a tether may be inserted.
A bioresorbable bone pin system for insertion into an aperture in a bone to fix a bioresorbable membrane or bony fragment to the bone, comprising:
- a pin portion having a shank and a head larger in diameter than said shank;
- and
- a handle portion coupled to said head and capable of being severed proximal to said head;
- wherein said handle portion includes an elongated shaft portion proximal to said head and a gripping portion distal from said head, said gripping portion being sufficiently large to be manually grasped by a user to insert the pin shank into the aperture in the bone and having a hole through which a tether may be inserted.
A method of fixing a bioresorbable membrane or bony fragment to a bony structure with a bioresorbable pin having a pin shank, a pin head, and a handle with an elongated shaft portion coupled to the pin head at one end thereof and a gripping portion at the other end thereof, the gripping portion being sufficiently large to be manually grasped by a user and having a hole through which a tether may be inserted, comprising the steps of:
- inserting a tether through the hole;
- inserting the pin shank through the membrane or fragment into an aperture in the bone;
- securing the pin shank to the bone;
- severing the shaft from the head;
- and
- after severing the shaft from the head, withdrawing the handle with the tether.
A method of fixing a bioresorbable membrane or bony fragment to a bony structure with a bioresorbable pin having a pin shank, a pin head, and a handle with an elongated shaft portion coupled to the pin head at one end thereof and a gripping portion at the other end thereof, the gripping portion being sufficiently large to be manually grasped by a user, and said shaft portion being smaller in diameter than said gripping portion, wherein the handle includes a hole, comprising the steps of:
- inserting a tether through the hole;
- inserting the pin shank through the membrane or fragment into an aperture in the bone;
- securing the pin shank to the bone;
- severing the shaft from the head, and,
- after severing the shaft from the head, withdrawing the handle with the tether.
