Question

Open reduction and internal fixation of posterior malleolar fractures is recommended when the posterior fragment is more than _______% to _________ % of the tibial plafond

Answer 1

Open reduction and internal fixation of posterior malleolar fractures is typically recommended when the posterior fragment constitutes about 25% to 40% of the tibial plafond, ensuring stability and proper healing.

Step-by-step explanation:

The question pertains to the management of posterior malleolar fractures, specifically when surgical intervention is recommended. An open reduction and internal fixation (ORIF) is generally recommended when the posterior fragment size is significant in relation to the tibial plafond. While the exact percentages might differ slightly based on the source, a common threshold for ORIF is when the posterior fragment constitutes about 25% to 40% of the articular surface of the tibial plafond. This is because larger fragments can influence the stability of the ankle joint and may affect overall function and outcome after healing.
