Abstract

Posterior pilon fracture is a common type of intraarticular fracture encountered in clinical practice. The treatment of this fracture pattern has been increasingly reported. However, methods for minimizing the associated surgical trauma and achieve effective fixation still require to be established. The present study involved 23 patients with posterior pilon fracture treated at the First Affiliated Hospital of Soochow University (Suzhou, China) between March 2013 and October 2017. Klammer's classification system was used to divide the posterior pilon fractures into 3 types. The surgical procedure, reduction of post‑operative fracture, peri‑operative complications and post‑operative functional recovery were reviewed and analyzed. The reduction in post‑operative fractures was evaluated by determining the Burwell‑Charnley scores at the last follow‑up. Anatomical reduction was confirmed in 17 patients, and an acceptable reduction was reported in 6 patients. The American Orthopedic Foot and Ankle Score was used to assess ankle function recovery; the average score was 82.3 points (range, 44‑97 points). In conclusion, the posterolateral approach is able to achieve anatomical exposure of the operative field. In addition, the posterior fracture fragment of the tibia may be fully exposed through the fibula fracture gap by retraction. Posterior placement of the plate may serve a definitive role in the fixation of the posterior fracture fragment and maintain stability in the anatomical reduction of the fracture, which is helpful in early functional rehabilitation.
