Option 2: Extended exposure
If the limited exposure is not sufficient for the reduction and fixation of a large Volkmann’s triangle, incise the fascia dorsal to the peroneal muscles at the border of the flexor hallucis longus muscle.
Beware of the sural nerve posteriorly.
Retract the peroneal muscles anteriorly and the flexor hallucis longus and the Achilles tendon dorsally.
Expose the posterior surface of the tibia.
Expose the fracture, and reflect the periosteum only sufficiently to control reduction of the dorsal posterior tibial fragment.
