Objective:
To study the guidance of four column theory in decision making of Pilon fractures and its result.
Methods:
Ninety-one cases of Pilon fractures classified by four column method and treated by open reduction internal fixation (ORIF) were reviewed from March 2005 to June 2009. Four column classification:lateral column of 67 cases were involved, posterior column of 34 cases were involved, medial column of 34 cases were involved and anterior column of 34 cases were involved. Among all the 94 fractures, single column of 20 fractures were involved, 2 columns of 49 fractures were involved, 3 columns of 15 fractures were involved and all of 4 columns of 10 fractures were involved.
Results:
Eighty-nine cases had been followed up. The average follow-up time was 16.2 months ranging between 6.0 and 39.0 months. The average healing time was 3.7 months ranging from 3.0 to 5.0 months. Reduction of 91% reviewed Pilon cases were good or acceptable according to Burwell and Charley's radiology evaluation system. Ankle function of 87.6% cases were excellent or good according to AOFAS evaluation system.
Conclusion:
As a simple and comprehensive classification, four column classification can contribute to reasonable operating decision making and good prognosis of Pilon fracture.
