Abstract
A fastener caddy for use with a bone plate. The fastener caddy includes preloaded fasteners that are positioned above the fastener apertures in the bone plate once the caddy is coupled to the bone plate. The caddy permits the driving of fasteners with the fastener already in proper alignment and without the need to retrieve each individual fastener. Once the fasteners are installed into the bone plate, the caddy is removed using an insertion tool.
Claims41
A surgical plate and caddy assembly, comprising:
- a bone plate having a top surface, a bottom surface, and a plurality of fastener apertures;
- a caddy coupled to said bone plate, said caddy having a top surface, a bottom surface, and at least two side surface, at least one removal aperture, and a plurality of fastener apertures that are aligned with said plurality of fastener apertures in said bone plate;
- wherein the caddy includes a clip portion having a tab that contacts said bone plate in order to couple the caddy to the bone plate;
- wherein the clip portion deflects to remove said tab from contact with said bone plate in order to remove the caddy from the bone plate;
- and
- wherein the at least one removal aperture provides an access to deflect the clip portion from contact with the bone plate;
- and
- a plurality of fasteners inserted into and held in said plurality of fastener apertures in said caddy by a flexible interface that deflects when the fasteners are advanced through the caddy fastener apertures into the aligned fastener apertures of the bone plate.

A method of installing fasteners into a bone plate, comprising:
- providing a caddy to have a top surface, a bottom surface, at least one deflectable clip portion having a tab, at least one removal aperture providing an access to the clip portion, and a plurality of fastener apertures;
- inserting fasteners into said fastener apertures in said caddy, wherein the fasteners are held in the caddy fastener apertures by a flexible interface that deflects when the fastener apertures are advanced through the caddy fastener apertures;
- using the at least one deflectable clip portion to removably couple said caddy to a bone plate comprising a plurality of fastener apertures such that the fastener apertures of said caddy are aligned with said fastener apertures in said bone plate;
- while the caddy is coupled to the bone plate, advancing said fasteners through the caddy fastener apertures and the bone plate fastener apertures to secure said bone plate to a bone;
- and
- using the at least one removal aperture to access and deflect the clip portion to remove said caddy from said bone plate.

(canceled)
A surgical fastener caddy guide that is used with a bone plate, comprising:
- a caddy body having a top surface, a bottom surface, and at least two side surfaces;
- at least one fastener aperture having a side wall including a slot;
- wherein said caddy body includes a first, deflectable clip member with a tab that engages the bone plate to couple the caddy guide to the bone plate and that deflects to remove the caddy guide from the bone plate;
- at least one clip member aperture in said caddy body providing an access to deflect the first clip member;
- and
- a preloaded fastener held in the at least one fastener aperture;
- and
- wherein said at least one fastener aperture includes at least one deflectable finger that is located in the slot of the side wall, said deflectable finger providing a flexible interface that holds the preloaded fastener in the at least one fastener aperture and that deflects to allow the preloaded fastener to advance through the at least one fastener aperture.
5 more elements
A surgical bone plate and preloaded fastener caddy combination, comprising:
- a) a surgical bone plate comprising one or a multiple of bone plate fastener apertures;
- b) a fastener caddy that is configured to be removably coupled to the surgical bone plate, wherein the fastener caddy comprises at least one caddy fastener aperture that is alignable with a bone plate fastener aperture when the fastener caddy is removably coupled to the surgical bone plate, and wherein the alignable caddy fastener aperture includes one or more flexible engagement elements that are configured to provide a flexible interface that holds a fastener in the alignable caddy fastener aperture and that deflects as the fastener held in the alignable caddy fastener aperture is advanced through the caddy fastener aperture;
- and
- c) a preloaded fastener that is held in the alignable caddy fastener aperture by the flexible interface.

- a) a surgical bone plate comprising a plurality of bone plate fastener apertures;
- b) a fastener caddy that is removably coupled to the surgical bone plate, wherein the fastener caddy comprises at least one fastener aperture that is aligned with a bone plate fastener aperture, and wherein the aligned caddy fastener aperture includes one or more flexible engagement elements that are configured to provide a flexible interface that holds a fastener in the alignable caddy fastener aperture and that deflects as the fastener held in the alignable caddy fastener aperture is advanced through the caddy fastener aperture;
- and
- c) a preloaded fastener that is held in the aligned caddy fastener aperture by the flexible interface while the fastener caddy is removably coupled to the surgical bone plate.
1 more element
A method of installing a fastener into a surgical bone plate, comprising the steps of:
- a) providing a fastener caddy comprising at least one caddy fastener aperture, wherein the caddy fastener aperture comprises one or more flexible engagement elements that are configured to provide a flexible interface that holds a fastener in the alignable caddy fastener aperture and that deflects as the fastener held in the alignable caddy fastener aperture is advanced through the caddy fastener aperture;
- b) providing a preloaded fastener held in the caddy fastener aperture by the flexible interface;
- c) providing an assembly in which the fastener caddy is removably coupled to the surgical bone plate while holding the preloaded fastener, wherein the surgical bone plate comprises a bone plate fastener aperture that is aligned with the caddy fastener aperture holding the preloaded fastener;
- and
- d) advancing the preloaded fastener through the fastener caddy aperture and into the aligned bone plate aperture, wherein the flexible interface deflects to permit the preloaded fastener to be advanced through the caddy fastener aperture and into the aligned bone plate fastener aperture.
2 more elements
A surgical bone plate and preloaded fastener caddy combination, comprising:
- a) a plurality of different surgical bone plates, wherein each of the different surgical bone plates has a plurality of fastener apertures, and wherein the different surgical bone plates have a common hole pattern;
- b) a preloaded fastener caddy that is configured to be removably coupled to each of the surgical bone plates, wherein the fastener caddy comprises a plurality of caddy fastener apertures having a hole pattern that is the same as the common hole pattern of the different surgical bone plate fastener apertures such that the caddy fastener apertures align with the fastener apertures of each of the different surgical bone plates when the fastener caddy is removably coupled to each of the different surgical bone plates, and wherein each caddy fastener aperture includes one or more flexible engagement elements that are configured to provide a flexible interface that holds a fastener in the caddy fastener aperture and that deflects as the fastener held in the caddy fastener aperture is advanced through the caddy fastener aperture;
- and
- c) at least one preloaded fastener that is held in a caddy fastener aperture by the flexible interface.
