The external thread form defines a pitch and a crest, the crest having a width in a range of about 35% to about 50% of the pitch of the external thread form, wherein the leading flank and the trailing flank are angled in a proximal orientation relative to the thread axis, and wherein the external thread form is configured to interlock with an internal thread form of an implant receiver. Systems, spinal constructs, implants and methods of use are disclosed.

Abstract: A surgical instrument includes a first member defining a passageway. The first member includes a first lock and a second lock. A second member is positioned in the passageway. A third member is coupled to the second member. The second member is movable relative to the first member to move the third member between a first position in which the first lock is spaced a first distance apart from the second lock, and a second position in which the first lock is spaced a reduced second distance apart from the second lock. Systems, spinal implants and methods are disclosed.

Abstract: A surgical instrument comprises a first arm including a first closed loop engageable with a first spinal implant disposed with a first vertebral surface. A second arm is movable relative to the first arm and includes a second closed loop engageable with a second spinal implant disposed with a second vertebral surface. Surgical systems, constructs, implants and methods are disclosed.
