Abstract

An external fixation clamp for receiving a fixation element includes an inner jaw and an outer jaw movable between an open position that permits the fixation element to be placed between the inner and outer jaws and a closed position that restricts removal of the fixation element from between the inner and outer jaws. A latch assembly may cooperate with the inner and outer jaws to secure the jaws in a closed position. The latch assembly may comprise a latch and a latch biasing member. The latch may be configured to translate linearly relative to one of the inner and outer jaws, and the latch biasing member may have a first higher level of stored energy when the inner and outer jaws are in the open position and a second lower level of stored energy when the inner and outer jaws are in the closed position.
