Insights
Limited tibial reduction and fixation (LTRF) for pilon fractures significantly speeds up definitive fixation and reduces overall operative time. This approach maintains comparable infection and reduction quality outcomes to traditional staged protocols.
Area of Science:
- Orthopedic surgery
- Trauma surgery
- Skeletal fixation techniques
Background:
- Pilon fractures are classically treated with staged protocols to minimize soft tissue complications.
- Traditional staged treatment involves external fixation followed by open reduction and internal fixation (ORIF).
- Alternative approaches aim to reduce complications associated with acute definitive fixation.
Purpose of the Study:
- To compare the outcomes of traditional staged pilon fracture treatment with a limited tibial reduction and fixation (LTRF) during the index procedure.
- To evaluate the impact of LTRF on time to definitive fixation and overall operative duration.
- To assess differences in infection rates, reduction quality, and nonunion rates between the two treatment groups.
Main Methods:
- Retrospective cohort study of 113 patients with pilon fractures treated between September 2012 and November 2018.
- Patients were divided into two groups: traditional staged protocol and LTRF during the index procedure.
- Key outcome measured was the time to definitive fixation; secondary outcomes included operative times, infection rates, reduction quality, and nonunion rates.
Main Results:
- The LTRF group showed a significantly shorter mean time to definitive ORIF (10.86 days) compared to the standard group (15.61 days).
- While the index procedure was longer in the LTRF group, the definitive ORIF operative time was reduced, leading to a shorter overall operative duration.
- No significant differences were observed in infection rates (3.1% LTRF vs. 2.5% standard), reduction quality, or nonunion rates between the groups.
Conclusions:
- Limited tibial reduction and fixation (LTRF) during the index procedure for pilon fractures leads to quicker definitive ORIF.
- LTRF reduces overall operative time without compromising infection rates, reduction quality, or union rates.
- This modified approach offers a viable alternative to traditional staged protocols for pilon fracture management.
Background:
The operative treatment of pilon fractures is classically treated with a staged protocol with ankle spanning external fixator, followed by definitive open reduction and internal fixation in order to decrease risk of soft tissue complications and infection. However, treatment of pilon fractures with patrial tibial fixation in addition to ankle spanning external fixation at the time of index procedure may facilitate final fixation while avoiding complications that were associated with acute definitive fixation.
Methods:
Retrospective cohort series of 113 patients treated for pilon fractures from September 2012 to November 2018 at a single level 1 trauma center. Charts were reviewed to compare patients who underwent traditional management with a staged protocol and those who had a limited tibial reduction and fixation (LTRF) during the index procedure. The main outcome measurement was time to definitive fixation.
Results:
Twenty-six percent of patients (29 of 113) had limited tibial reduction and fixation (LTRF) during index surgery. Mean time between index procedure and definitive ORIF was 4.75 days less for LTRF cohort compared to standard stage cohort (10.86 ± 7.44 vs. 15.61 ± 8.59 days, P = .009). The index procedure took on average 51 minutes longer in the LTRF cohort (P < .001), yet definitive procedure operative time was decreased by an average of 98 minutes (P < .001), and overall (index plus definitive) operative duration was shortened by an average of 50 minutes (P = .044). There was no difference in rate of infection between LTRF (3.1%) and traditional treatment (2.5%) (P = .86) or reduction quality (P = .270). There were no nonunions in either treatment group.
Conclusion:
Patients who had LTRF had quicker time to definitive ORIF and decreased operative time for definitive ORIF. There was no difference in infection rate, reduction quality, or nonunion rate between groups.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
