The body includes a through-bore configured for receiving a fastener and an end configured for contacting a bone plate. The fastener guide further includes at least one member configured for contacting and retaining the fastener within the body. ## Claims ### Claim 1 A fastener guide for guiding a fastener into a hole of a bone plate, comprising: a body comprising a through-bore configured for receiving the fastener and an end configured for contacting the bone plate to align the fastener relative to the hole of the bone plate; a pair of deformable arms configured for selectively engaging the bone plate; a collar slidably attached to the body, a handle member connected to the body, and a biasing member located in between the collar and the handle member; and at least one member configured for contacting and retaining the fastener within the body. ### Claim 2 (depends on 1) The fastener guide of claim 1, wherein the at least one member extends at least partially into the through-bore. ### Claim 3 (depends on 1) The fastener guide of claim 1, wherein the at least one member is approximately parallel to the through-bore. ### Claim 4 (depends on 1) The fastener guide of claim 1, wherein the at least one member comprises two deformable members configured for flexing inwardly to hold the fastener and flexing outwardly as the fastener moves downwardly through the through-bore. ### Claim 5 (depends on 1) The fastener guide of claim 1, wherein the pair of deformable arms are in the form of a pair of leaf-spring arms which are outwardly biased such that a downward movement of the collar pushes the pair of leaf-spring arms inwardly so that the pair of leaf-spring arms grip onto the bone plate. ### Claim 6 (depends on 1) The fastener guide of claim 1, wherein the at least one member is in the form of a compression member internally disposed within the body, the compression member being configured for contacting and retaining the fastener. ### Claim 7 (depends on 6) The fastener guide of claim 6, wherein the compression member comprises an open top and at least two compression arms extending downwardly from the top. ### Claim 8 (depends on 1) The fastener guide of claim 1, wherein the body further comprises at least two slits which form the at least one member. ### Claim 9 (depends on 8) The fastener guide of claim 8, wherein the through-bore is tapered such that the at least one member outwardly flexes as the fastener moves downwardly through the through-bore. ### Claim 10 (depends on 1) The fastener guide of claim 1, wherein the handle member comprises a magazine coupled to the body, the magazine being configured for storing multiple fasteners and dispensing the fasteners into the body. ### Claim 11 A fastener guide for guiding a fastener into a hole of a bone plate, comprising: a body comprising a through-bore configured for receiving the fastener and an end configured for contacting the bone plate to align the fastener relative to the hole of the bone plate; at least one member configured for contacting and retaining the fastener within the body; forceps; a pair of deformable arms configured for selectively engaging the bone plate; and a collar member connecting the forceps to the body and being configured for moving the deformable arms for selectively gripping onto the bone plate. ### Claim 12 (depends on 11) The fastener guide of claim 11, wherein the at least one member comprises two deformable members configured for flexing inwardly to hold the fastener and flexing outwardly as the fastener moves downwardly through the through-bore. ### Claim 13 (depends on 11) The fastener guide of claim 11, wherein the pair of deformable arms are in the form of a pair of leaf-spring arms which are outwardly biased such that a downward movement of the collar member pushes the pair of leaf-spring arms inwardly so that the pair of leaf-spring arms grip onto the bone plate. ### Claim 14 A fastener guide for guiding a fastener into a hole of a bone plate, comprising: a body comprising a through-bore configured for receiving the fastener and an end configured for contacting the bone plate to align the fastener relative to the hole of the bone plate; and at least one member configured for contacting and retaining the fastener within the body, wherein the end of the body is externally threaded for threading into the bone plate and configured for breaking away upon being threaded into the bone plate. ### Claim 15 (depends on 14) The fastener guide of claim 14, wherein the at least one member is approximately parallel to the through-bore. ### Claim 16 (depends on 14) The fastener guide of claim 14, wherein the at least one member comprises two deformable members configured for flexing inwardly to hold the fastener and flexing outwardly as the fastener moves downwardly through the through-bore. ### Claim 17 (depends on 14) The fastener guide of claim 14, wherein the body further comprises at least two slits which form the at least one member. ### Claim 18 (depends on 14) The fastener guide of claim 14, wherein the end of the body and the bone plate are made of the same material. ### Claim 19 (depends on 18) The fastener guide of claim 18, wherein the end of the body and the bone plate are comprised of metal. ### Claim 20 (depends on 14) The fastener guide of claim 14, wherein the end of the body is internally threaded for threadingly engaging the fastener.
