Management of complex pilon fractures: Is it necessary to fix all the columns in AO/OTA type 43-C fractures?

Surgical treatment of AO/OTA 43-C pilon fractures has not yet taken a standard form. We aimed to evaluate whether patients that appeared to be labelled as unsupported columns according to the four-column theory would affect long-term clinical and radiological outcomes. Patients with AO/OTA 43-C type...

Zusammenfassung:Surgical treatment of AO/OTA 43-C pilon fractures has not yet taken a standard form. We aimed to evaluate whether patients that appeared to be labelled as unsupported columns according to the four-column theory would affect long-term clinical and radiological outcomes. Patients with AO/OTA 43-C type who were treated surgically between January 2010 and December 2019 were included in the study. 53 fractures in 52 patients who received osteosynthesis were categorized based on the fixed columns. These groups were formed as fully supported columns (FSC- Group A), partly supported columns (PSCGroup B), Ankle range of motions (ROM), Burwell Charnley's reduction evaluation criteria, Kellgren-Lawrence ankle osteoarthritis staging system, and American Orthopedic Foot and Ankle Society (AOFAS) Scoring System, Olerud-Molander Ankle Score, Visual Analog Scale were used for evaluating radiological and functional outcomes . The mean follow-up was 72.6 (12-131) months. Mean age was 42.6 (18-76). Two groups were homogenously distributed in terms of age (p=0.785), sex (p=0.376), laterality (p=0.732), smoking status (p=0.488) and reduction quality. There was no difference in AOFAS score (p=0.452), Olerud-Molander score (p=0.354) and VAS scores (p=0.589). TAS, TLS and TT angle measurements suggested no difference between groups (p=0.493, p=0.834, p=0.577). There was no difference between groups in terms of infection (p=0.734), malunion (p=0.688) and arthritis (p=0.483) We presented findings that contradicted the hypothesis positing the existence of four distinct columns in pilon fractures, as well as the notion that each fractured column requires support from distinct implants.
