Application of a distractor intraoperatively greatly assists with articular visualization and alignment of several of the major articular fragments. A temporary joint bridging external fixator is typically replaced with a distractor during definitive articular surface reduction and fixation.

To apply the distractor laterally, a 4 mm Schanz pin is placed transversely from lateral to medial into the talar neck, through the surgical incision. A second 4 mm Schanz pin is placed from lateral to medial into the tibial shaft, proximal to the intended plate. The distal pin, anterior to the axis of rotation of the talus, produces ankle joint distraction and plantarflexion, maximizing articular visualization. The threaded rod of the distractor is placed posterolaterally, away from the incision.
