Abstract
A closure for use in conjunction with an open headed medical implant for capturing and locking a rod member in the implant comprises a radially outward threaded cylindrical body sized and shaped to be threadably received between two arms of a head of the implant. The closure also includes a driving head and a coaxial removal head. The driving head breaks away from the body at a predetermined torque leaving the removal head. The driving head and removal head are of sufficiently dissimilar shape to prevent a tool with a socket for gripping the driving head from inadvertently gripping the removal head during installation and over-torquing the closure.
