Abstract

Background: This systematic review evaluates postoperative complications and functional outcomes of minimally invasive plate osteosynthesis (MIPO) for distal tibial pilon fractures. This paper aims to fill a key literature gap, as no previous reviews have specifically addressed MIPO for tibial pilon fractures or fractures other than those involving the humeral shaft. Methods: This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic literature search was done using PubMed, Embase, Web of Science, and Scopus databases from 2000 to 2022. Inclusion criteria were MIPO treatment in skeletally mature patients, while exclusion criteria were non-English papers, conference abstracts, papers with multiple treatment modalities that didn't analyze MIPO outcomes separately, skeletally immature patients, case reports, and cohorts smaller than five patients. Unpublished papers were also searched using Clinical Trials. Data extraction included general study information, injury specification, outcome measures, and complications. Finally, a risk of bias assessment (RoB) was performed. Results: A total of 1732 studies were identified, of which 23 were included in this review, with 673 patients and 678 fractures analyzed. The mean follow-up ranged from 6 to 62.53 months, with most studies representing intermediate to long-term follow-up. Primary outcome measures showed that 87.33% achieved 'excellent to good' results, 8.67% achieved 'fair' results, and 4% achieved 'poor' results. Stratified by fracture type, 76.47%, 80.05%, and 76.92% of AO/OTA type A, B, and C fractures, respectively, achieved 'excellent to good' results. 35.06% of cases reported complications (236 in total). These included one case of deep infection (0.148%), 28 superficial wound infections (4.16%), 4 nonunion cases (0.59%), and 22 malunion instances (3.27%). RoB assessment showed that 52.17% had a moderate overall risk of bias, 39.13% had a serious overall risk of bias, and 8.7% had a critical overall risk of bias. Conclusion: MIPO technique for pilon fractures showed good functional outcomes and reliability, with low complication rates and should be considered in cases where proper indirect reduction is possible. However, while the evidence is promising, further high-quality studies with larger sample sizes, longer-term follow-up, and comparison to other techniques are needed to evaluate the efficacy and safety of this technique.
