Paragraph Number

47

Specifically, each of the rotatable structures 112 may sit in a recess 120 manufactured into an outer surface of the bone plate 108. In one embodiment, the recess 120 may be a partially circular recess 120. Further, each of the partially circular recesses 120 may define a niche 130 that can receive either of two ears 132 protruding from a central hub 134 of the rotatable structure 112. One of the ears 132 may reside in the niche 130 in the locked orientation, and the other may reside in the niche 130 in the unlocked orientation. As the rotatable structure 112 approaches the locked orientation or the unlocked orientation, the corresponding ear 132 may slide into the niche 130, causing the rotatable structure 112 to “snap” into the locked configuration or the unlocked configuration. The engagement of an ear 132 within the niche 130 can provide either an audible “snap” as the two parts engage and/or the engaging ear 132 and niche 130 can provide a tactile movement that an operator can feel in a driver (not shown) that engages the drive feature 118 of the rotatable structure 112 to move the rotatable structure 112 into a locked orientation. Similarly, engagement of an ear 132 within the niche 130 can provide a tactile feedback to an operator using the driver to move the rotatable structure 112 into an unlocked orientation
