An external fixator system comprising: an external fixator assembly comprising: a first shaft having a first coupling end and a first free end; a second shaft having a second coupling end and a second free end; a coupling pivotally retaining the first coupling end and the second coupling end; a first clamp assembly disposed on the first shaft between the coupling and the first free end, the first clamp assembly comprising: a first inner clamp member disposed proximate to the coupling, the first inner clamp member having a first inner slot; a first outer clamp member disposed proximate to the first free end, the first outer clamp member having a first outer slot; a first biasing member disposed in the first inner slot and the first outer slot such that first biasing member biases the first inner clamp member toward the first outer clamp member; a second clamp assembly disposed on the second shaft between the coupling and the second free end, a first nut threaded onto the first shaft to secure first clamp assembly and a second nut threaded onto the second shaft to secure second clamp assembly; the second clamp assembly comprising: a second inner clamp member disposed proximate to the coupling, the second inner clamp member having a second inner slot; a second outer clamp member disposed proximate to the second free end, the second outer clamp member having a second outer slot; a second biasing member disposed in the second inner slot and the second outer slot such that the second biasing member biases the second inner clamp member toward the second outer clamp member; a pin configured to engage bone, a portion of the pin configured to be received in the first or second clamp assembly; and a rod configured to be received in the other of the first or second clamp assembly. a first shaft having a first coupling end and a first free end; a second shaft having a second coupling end and a second free end; a coupling pivotally retaining the first coupling end and the second coupling end; a first clamp assembly disposed on the first shaft between the coupling and the first free end, the first clamp assembly comprising: a first inner clamp member disposed proximate to the coupling, the first inner clamp member having a first inner slot; a first outer clamp member disposed proximate to the first free end, the first outer clamp member having a first outer slot; a first inner clamp member disposed proximate to the coupling, the first inner clamp member having a first inner slot; a first outer clamp member disposed proximate to the first free end, the first outer clamp member having a first outer slot; a first biasing member disposed in the first inner slot and the first outer slot such that first biasing member biases the first inner clamp member toward the first outer clamp member; a second clamp assembly disposed on the second shaft between the coupling and the second free end, a first nut threaded onto the first shaft to secure first clamp assembly and a second nut threaded onto the second shaft to secure second clamp assembly; the second clamp assembly comprising: a second inner clamp member disposed proximate to the coupling, the second inner clamp member having a second inner slot; a second outer clamp member disposed proximate to the second free end, the second outer clamp member having a second outer slot; a second inner clamp member disposed proximate to the coupling, the second inner clamp member having a second inner slot; a second outer clamp member disposed proximate to the second free end, the second outer clamp member having a second outer slot; a second biasing member disposed in the second inner slot and the second outer slot such that the second biasing member biases the second inner clamp member toward the second outer clamp member; a pin configured to engage bone, a portion of the pin configured to be received in the first or second clamp assembly; and a rod configured to be received in the other of the first or second clamp assembly.
