Abstract
A bone hook apparatus is provided that includes a base, a rod receptacle disposed on a proximal side of the base, a first hook distally extending from the base and oriented in a first direction, and a second hook distally extending from the base and oriented in a second direction opposing the first direction, the first hook and second hook together configured to receive the bone. Kits and spinal constructs employing the bone hook apparatus are also described.
Claims19
A bone hook apparatus for securing a rod to a bone, the bone hook apparatus comprising:
- a base;
- a rod receptacle disposed on a proximal side of the base;
- a first hook immovably associated with the base and extending therefrom, the first hook oriented in a first direction;
- and
- a second hook immovably associated with the base and extending distally therefrom, the second hook oriented in a second direction opposing the first direction, the first hook and second hook together configured to receive the bone therebetween, the second hook offset from the first hook thereby bounding a first passage between the first and second hook, the first passage configured to be positioned over the bone during insertion of the bone hook apparatus,
- wherein the base, rod receptacle, first hook, and second hook are integrally formed from biocompatible material.
A bone hook apparatus for securing a rod to a bone, the bone hook apparatus comprising:
- a base comprising a proximal side and a distal side;
- a rod receptacle disposed on a proximal side of the base;
- a first hook extending distally from the base, the first hook comprising a first hook blade extending in a first direction;
- and
- a second hook extending distally from the base, the second hook comprising a second hook blade extending in a second direction, wherein the second direction is opposite to the first direction, the second hook offset from the first hook thereby bounding a first passage between the first and second hook, the first passage configured to be positioned over the bone during insertion of the bone hook apparatus,
- wherein the base, rod receptacle, first hook, and second hook are integrally formed from biocompatible material.
A method of securing a bone hook apparatus to a bone, comprising:
- providing a bone hook apparatus including:
- a base including a proximal side, a distal side, a first side, and a second side opposite to the first side;
- a rod receptacle;
- a first hook extending distally from the base adjacent the first side thereof and including a first hook blade extending in a first direction;
- and
- a second hook extending distally from the base adjacent the second side thereof and including a second hook blade extending in a second direction, wherein the second direction is opposite to the first direction;
- wherein the base, first hook, and second hook are integrally formed from a biocompatible material;
- positioning the bone hook apparatus so that the base is proximate to a proximal side of the bone and the first hook and second hook including the first blade and the second blade extend on opposing sides of the bone in an initial orientation, wherein a first passage between the first and second hook is positioned over the bone;
- and
- rotating the bone hook apparatus to a final orientation so as to engage the first hook and the second hook with the bone wherein the first blade and second blade extend across a distal side of the bone, wherein a second passage orthogonal to the first passage is positioned over the bone.
