A bone fastener includes a first member fixable with a proximal portion and includes a wall defining a groove. The wall includes an inner surface defining a first mating surface and a lateral surface defining a cavity. A second member is configured for fixation with the first member and includes a second mating surface engageable with the first mating surface. A third member defines an opening and is disposable with the groove such that the opening is aligned with the cavity. A distal portion includes a first end disposed within the members and a second end configured to penetrate tissue. The distal portion is movable relative to the proximal portion between a first orientation and a second orientation. Systems and methods are disclosed. |
