Tibial pilon fractures are difficult to treat, and periarticular external fixation may produce good results. However, the TL-HEX TraumaTM has not been evaluated for this fracture type. This study found that the union rate and time to union with PAEF were lower compared to other studies.
Introduction: Tibial pilon fractures are a treatment challenge, since there is no true gold standard treat-ment, and because of potential skin complications. Periarticular external fixation (PAEF) appears to produce good results, but the outcomes with the TL-HEX TraumaTM (Orthofix (R), Verona, Italy) have not yet been evaluated. We performed a study with the following objectives: 1) evaluate time to union and union rate; 2) determine clinical and radiological results; 3) detect complications.Hypothesis: PAEF will produce comparable fracture union to other external fixator techniques for tibial pilon fractures.Methods: A single center, retrospective study, was done between June 2016 and December 2018. Patients who had a tibial pilon fracture operated with a PAEF were included if they had a minimum of 12 months' follow-up. Forty-seven patients were included; the mean follow-up was 2.45 years (1.2-3.7). The primary endpoint was the time to union and union rate at the final assessment. The secondary endpoints were the joint range of motion, residual pain (VAS), functional scores (AOFAS and SF12) and complication rate. Results: The union rate was 70% (33/47) and the mean time to union was 201 +/- 79 days (89-369). The range of motion was significantly reduced relative to the contralateral side. Twenty patients had residual pain that averaged 2.9 (1-6) on the VAS. The mean AOFAS score was 74 points (51-95). Twenty patients (43%) suffered at least one complication.Discussion: While a PAEF helps to avoid skin complications, in our study, it was associated with a lower union rate and longer time to union than in other published studies. This difference is likely due to a higher rate of open fractures and high-energy trauma in our study, different protocol for return to weightbearing and a different external fixator than other studies. This is the first study reporting the results of the TL-HEX Trauma in this indication.Level of evidence: IV, retrospective study.(c) 2021 Elsevier Masson SAS. All rights reserved.
