Abstract

BACKGROUND: Comminuted intra-articular tibial pilon fractures can be challenging to manage, with high revision rates and poor functional outcomes. This study reviewed [1] treatment, complications, and clinical outcomes in studies of complex comminuted tibial pilon fractures (type AO43-C3); and [2] primary ankle arthrodesis as a management option for these types of complex injuries.

METHODS: A systematic literature search was performed on PubMed from 1990 to 2020 to determine complications and outcomes after staged fracture fixation and primary ankle joint arthrodesis for comminuted C3-type tibial pilon fractures. The search was conducted in compliance with the PRISMA guidelines, using the following MeSH terms: "tibial pilon"/"pilon fracture"/"plafond fracture"/"distal tibial"/"43-C3"/"ankle fracture"/"ankle fusion"/"primary ankle arthrodesis"/"pilon fracture staged"/"pilon external fixation" and "pilon open reduction internal fixation." Inclusion criteria were restricted to original articles in English language on adult patients ≥18 years of age. Eligibility criteria for retrieved publications were determined using a "PICO" approach (population, intervention/exposure, comparison, outcomes). Weighted analysis was used to compare treatment groups on time to definitive treatment, follow-up time, range of motion, fracture classification, and complications.

RESULTS: The systematic literature review using the defined MeSH terms yielded 72 original articles. Of these, 13 articles met the eligibility criteria based on the PICO statements, of which 8 publications investigated the outcomes of a staged fixation approach in 308 cumulative patients, and 5 articles focused on primary ankle arthrodesis in 69 cumulative patients. For staged treatment, the mean wound complication rate was 14.6%, and the malunion/nonunion rate was 9.9%. For primary arthrodesis, the mean wound complication rate was 2.9%, and the malunion/nonunion rate was 2.9%. After risk stratification for fracture type and severity, the small cumulative cohort of patients included in the primary arthrodesis publications did not provide sufficient power to determine a clinically relevant difference in complications and long-term patient outcomes compared to the staged surgical fixation group.

CONCLUSIONS: At present, there is insufficient evidence in the published literature to provide guidance towards consideration of ankle arthrodesis for complex comminuted C3-type tibial pilon fractures, compared to the standard treatment by staged surgical fracture fixation.
