In some embodiments, compliant orthopedic driver includes a body extending from a proximal end to a distal end along a driver axis; a driver tip disposed at the distal end of the body, wherein the body includes at least one compliant portion configured to allow the driver flex about at least two axes transverse to the driver axis. ## Claims ### Claim 1 A compliant orthopedic driver, comprising: a body extending from a proximal end to a distal end along a driver axis; a driver tip disposed at the distal end of the body; wherein the body includes at least one compliant portion configured to allow the body to flex about at least two axes transverse to the driver axis, the compliant portion including: a first round notch adapted to flex about a first axis transverse to the driver axis; and a second round notch longitudinally disposed from the first notch and adapted to flex about a second axis transverse to the driver axis, the first axis being angularly offset from the second axis. ### Claim 2 (depends on 1) The driver of claim 1, wherein the first axis is angularly offset from the second axis by 90 degrees. ### Claim 3 (depends on 1) The driver of claim 1, wherein the compliant portion includes a pair of oppositely disposed concave notches relative to the driver axis. ### Claim 4 (depends on 1) The driver of claim 1, wherein the at least one compliant portion includes a pair of stops configured to limit an amount of flexure of the body about the at least two axes. ### Claim 5 (depends on 1) The driver of claim 1, wherein the at least one compliant portion includes two compliant portions longitudinally spaced apart by a predetermined distance. ### Claim 6 (depends on 5) The driver of claim 5, wherein the two compliant portions comprise a first pair of round notch hinges and a second pair of round notch hinges, each of which includes a first pair of round notches and a second pair of round notches angularly offset from the first pair of notches. ### Claim 7 (depends on 6) The driver of claim 6, wherein the first pair of notches is perpendicular to the second pair of notches. ### Claim 8 (depends on 6) The driver of claim 6, wherein each notch of the first pair of notches has a first predetermined radius and each notch of the second pair of notches has a second predetermined radius, and wherein the first pair of notches are separated by a first predetermined thickness and the second pair of notches are separated by a second predetermined thickness. ### Claim 9 (depends on 5) The driver of claim 5, wherein the two compliant portions include a first reduced diameter section having a first predetermined length and a second reduced diameter section having a second predetermined length. ### Claim 10 (depends on 1) The driver of claim 1, wherein the at least one compliant portion includes a reduced diameter section having a predetermined length. ### Claim 11 (depends on 1) The driver of claim 1, wherein the at least one compliant portion includes a pair of stops configured to limit an amount of flexure of the driver about the at least two axes. ### Claim 12 A compliant orthopedic driver, comprising: a body extending from a proximal end to a distal end along a driver axis; a driver tip disposed at the distal end of the body, wherein the body includes a first compliant portion and a second compliant portion longitudinally spaced apart from the first compliant portion along the body, and wherein each of the first and second compliant portions is configured to allow the driver to flex about at least two axes transverse to the driver axis; wherein each compliant portion includes: a first round notch adapted to flex about a first axis transverse to the driver axis; and a second round notch longitudinally disposed from the first notch and adapted to flex about a second axis transverse to the driver axis, the first axis being angularly offset from the second axis. ### Claim 13 (depends on 12) The driver of claim 12, wherein the first axis is angularly offset from the second axis by 90 degrees. ### Claim 14 (depends on 12) The driver of claim 12, wherein the compliant portion includes a pair of oppositely disposed concave notches relative to the driver axis. ### Claim 15 (depends on 12) The driver of claim 12, wherein at least one of the compliant portions includes a pair of stops configured to limit an amount of flexure of the body about the at least two axes. ### Claim 16 (depends on 12) The driver of claim 12, wherein the first and second compliant portions comprise a first pair of round notch hinges and a second pair of round notch hinges, each of which includes a first pair of round notches and a second pair of round notches angularly offset from the first pair of notches. ### Claim 17 (depends on 16) The driver of claim 16, wherein the first pair of notches is perpendicular to the second pair of notches. ### Claim 18 (depends on 16) The driver of claim 16, wherein each notch of the first pair of notches has a first predetermined radius and each notch of the second pair of notches has a second predetermined radius, and wherein the first pair of notches are separated by a first predetermined thickness and the second pair of notches are separated by a second predetermined thickness. ### Claim 19 (depends on 16) The driver of claim 16, wherein the first and second compliant portions include a first reduced diameter section having a first predetermined length and a second reduced diameter section having a second predetermined length.
