摘要：
A bone fixation device adapted to be coupled to bone anchors that allows movement of rods to permit a screw-rod construct to lengthen in response to bone growth without necessitating post surgical installation adjustment of the device. The bone fixation device includes a locking mechanism that is operably associated with a housing to allow relative movement of a rod and a housing in a first direction and inhibiting relative movement of the rod and the housing in a second direction.
