BACKGROUND: Although pilon fractures are rare, they are important for orthopedic surgeons because of the difficulty of treatment and adverse effects on gait function. The aim of the study to evaluate the relationship between the reduction quality of the fracture, functional results, ankle arthrosis and plantar pressure distribution in patients with tibia pilon fractures. METHODS: In this study, a total of 62 patients treated for an intraarticular pilon fracture in our clinic between January 2015 and January 2019 were evaluated retrospectively. Postoperative reduction qualities of the patients were evaluated with the Ovadia-Beals criteria, ankle functional scores with the Teeny-Wiss score, and ankle arthrosis with the Takakura classification. In the last follow-up of the patients, foot loading analysis was performed and the results of the patients were evaluated for their relation with postoperative reduction quality, ankle functions and ankle arthrosis. RESULTS: There were 62 patients (50 men and 12 women). The average age was 43.3 years (range 19-78). The mean follow-up was 34.3 months (range 24 - 58). The mean Ovadia-Beals score was 12.35 {plus minus} 4.6 in the postoperative plain radiographs of the patients; the mean Teeny-Wiss score in the last follow-up was 76.82 {plus minus} 17.69, and the Takakura score was 1.47 {plus minus} 1.35. Based on the pedobarographic measurements, 47.58% of the patients put weight on the anterior and 52.42% on the posterior of the foot in the anteroposterior plane. In the mediolateral plane, 42.15% loaded on the medial of the ankle and 57.85% loaded on the lateral of the foot. CONCLUSION: Intra-articular tibia pilon fractures can be demonstrated by lateralization of the walking axis and changes in gait patterns and can be associated with clinical outcome.
We present a case of tibial pilon fracture where only the lateral part of the distal tibia was affected. The transfibular approach to the ankle was used for the surgical treatment of the fracture. After an initial nonweightbearing period of 3 weeks, full weightbearing was allowed 8 weeks after surgery. The second-year follow-up showed no evidence of degenerative signs, with full ankle range of motion.

The surgical management of distal intra-articular comminuted fracture of the tibia (pilon fracture) is difficult because complications frequently develop. The minimally invasive plate osteosynthesis technique is generally accepted for this type of fracture. In this study, complications developed after open reduction and internal fixation using multiple miniplates for accurate reduction of small fracture fragments. Therefore, when we use this technique, we need to pay attention to the development of complications such as nonunion, avascular necrosis, and osteomyelitis by the disruption of both endosteal blood supply by fracture and periosteal blood supply during approach or reduction.
Background: Tibia pilon fractures are associated with high complication rates, decreased quality of life, and low patient satisfaction. Although many factors such as reduction quality and soft-tissue coverage have been identified, researchers continue to investigate the factors that affect healing in tibia pilon fractures. Our objective was to investigate the effect of initial fracture crack width and displacement degree on clinical functional results in tibia pilon fractures.
Methods: In this retrospective cohort study, 40 patients with Arbeitsgemeinschaft für Osteosynthesefragen and Orthopaedic Trauma Association type 43B and 43C tibia pilon fractures and operated on through the extensile anteromedial approach were analyzed. The demographic data of the patients, injury mechanisms, fracture type, reduction quality, clinical results, and postoperative complications were recorded. To evaluate the objective quantity of initial fracture crack width and displacement, a new parameter was defined: “fracture area.” All measurements were conducted using a feature from the picture archiving and communication system on anteroposterior and lateral radiographs taken separately in standard fashion.
Results: With an average follow-up period of 29.2 months (range, 24–40 months), 34 patients (85%) had excellent or good results, whereas only two patients (5%) had poor clinical results. Age, injury mechanism, and reduction quality have a significant relationship with Maryland Foot Score (P < .001, P < .037, and P < .001, respectively). Preoperative fracture area, measured on both the anteroposterior and the lateral views, are significantly related to both Ovadia-Beals Score and Maryland Foot Score (P < .001 for each).
Conclusions: Preoperative fracture area measurement has a major effect on healing of tibia pilon fractures. Increased initial fracture area is correlated with poor clinical functional results. High-energy injuries, older age, and poor reduction quality are also related to worse clinical outcomes.
This article presents a case of a tibial pilon fracture following a motor-vehicle accident. It discusses the main classification system and mechanism of injury for such fractures and emphasizes an alternative form of treatment of the usually suggested ankle fusion: an arthrectomy, which allows motion, thereby salvaging the ankle joint.
Talar injuries that are associated with pilon fractures include talar body fractures, osteochondral defects, and posterior process talar fractures. Pilon fractures, in combination with talar dome fractures, have not yet been reported in the scientific literature. We report the case of a 15-year-old boy who sustained a pilon fracture with a lateral talar dome fracture. The pilon fracture was initially fixed using a temporary external fixator for soft-tissue care. After the swelling subsided, definitive internal fixation was performed. First, the lateral talar dome fracture was directly reduced and fixed using a small anterolateral approach of the ankle. Then, the intra-articular portion of the pilon fracture was directly reduced using the same anterolateral approach and an additional small anteromedial approach, and the extra-articular metaphyseal portion of the pilon fracture was indirectly reduced. The pilon fracture was finally fixed with an anterolateral distal tibia plate, using a submuscular plating technique through the anterolateral approach and a separate proximal skin incision. A medial distal tibia plate was later added using a subcutaneous plating technique through the anteromedial approach and another proximal skin incision. Both the pilon fracture and the lateral talar dome fracture were addressed simultaneously through a combination of the small anterolateral and anteromedial approaches.
Background:
The treatment of pilon tibia fractures is challenging. Anatomical reduction of the joint surface is essential. Excessive soft-tissue dissection may interfere with the blood supply and can result in nonunion. We sought to compare the outcomes of distal tibia fractures treated with medial locking plates versus circular external fixators.
Methods:
We retrospectively evaluated 41 consecutive patients with closed pilon tibia fractures treated with either minimally invasive locking plate osteosynthesis (n = 21) or external fixation (EF) (n = 20). According to the Ruedi and Allgower classification, 23 fractures were type B and 18 were type C. Soft-tissue injury was evaluated according to the Oestern and Tscherne classification. Time to fracture union, complications, and functional outcomes were assessed annually for 3 years with the American Orthopaedic Foot and Ankle Society (AOFAS) ankle score.
Results:
Mean ± SD values in the plate group were as follows: age, 42.4 ± 14 years; union time, 19.4 ± 2.89 weeks (range, 12–26 weeks); and AOFAS ankle scores, 86.4 ± 2.06, 79.5 ± 1.03, and 77.9 ± 0.80 at 1, 2, and 3 years, respectively. Four patients in the plate group needed secondary bone grafting during follow-up. In the EF group (mean ± SD age, 40.7 ± 12.3 years), all of the patients achieved union without secondary bone grafting at a mean ± SD of 22.1 ± 1.7 weeks (range, 18–24 weeks). In the EF group, mean ± SD AOFAS ankle scores were 86.6 ± 1.69, 82.1 ± 0.77, and 79.7 ± 1.06 at 1, 2, and 3 years, respectively. There were no major complications. However, there were soft-tissue infections over the medial malleolus in five patients in the plate group and grade 1-2 pin-tract infections in 13 patients and grade 3 pin-tract infections in one patient in the EF group. Post-traumatic arthritis was detected in eight plate group patients and seven EF group patients.
Conclusions:
Minimally invasive plating and circular EF methods have favorable union rates with fewer complications.
In this prospective study, 30 patients (28 men and 2 women) with open ankle fractures were treated with early debridement and immediate stable internal fixation after anatomical reduction to achieve better functional results after early mobilization. The procedure was performed an average of 8 hours (range, 6–15 hours) after injury. According to the classification system of Gustilo and Anderson, 11 fractures (37%) were grade I, 12 (40%) were grade II, 5 (17%) were grade IIIA, and 2 (7%) were grade IIIB. Six complications occurred: four patients had superficial skin necrosis and two had loss of reduction, resulting in residual ankle stiffness. Twenty patients had excellent results, eight had good results, and two had fair results according to the modified criteria of Ketenjian and Shelton. We found that immediate debridement, anatomical reduction, and internal fixation of open ankle fractures leads to better functional results, especially in grade I and grade II injuries.
