Purpose: The study described a novel surgical treatment of Haraguchi type 1 posterior malleolar fracture in tri-malleolar fracture and patient outcomes at intermediate period follow-up. Methods: All patients from January 2015 to December 2017 with tri-malleolar fracture of which posterior malleolar fractures were Haraguchi type 1, were surgically treated in this prospective study. Lateral and medial malleolar fractures were managed by open reduction and internal fixation through dual incision approaches. 36 cases of Haraguchi type 1 posterior malleolar fractures were randomly performed by percutaneous posteroanterior screw fixation with the aid of medial exposure (group 1). And 40 cases were performed by percutaneous anteroposterior screw fixation (group 2). Clinical outcomes, radiographic outcomes and patient-reported outcomes were recorded. Results: Seventy-six patients with mean follow-up of 30 months were included. There were no significant differences in the mean operation time (81.0 ± 11.3 vs. 77.2 ± 12.4), ankle function at different periods of follow-up, range of motions and visual analog scale (VAS) at 24 months between the two groups ( p > 0.05). However, the rate of severe post-traumatic arthritis (Grade 2 and 3) and the rate of step-off rather than gap in radiological evaluation were lower in group 1 than that in group 2 ( p < 0.05). Conclusion: Using our surgical technique, more patients had good outcome with a lower rate of severe post-traumatic arthritis, compared with the group of percutaneous anteroposterior screw fixation. Percutaneous posteroanterior screw fixation can be a convenient and reliable alternative in treating Haraguchi type 1 posterior malleolar fracture.

Supporting Structures

A cadaver study was conducted to evaluate the role of the posterior tibial margin or posterior malleolus, as well as medial and lateral supporting structures, in providing posterior stability for the talus. Posterior malleolar fractures consisting of approximately 30%, 40%, and 50% of the articular margin on the lateral radiograph were created in specimens that were then subjected to posterior stressing. No posterior talar subluxation was noted in any specimen. Repeat stressing following removal of the medial malleolus again revealed no subluxation in any specimen. The lateral supporting structures, primarily the posterior fibulotalar and fibulocalcaneal ligaments, appeared to be the key structures providing posterior talar stability. If the fibula is stable in an anatomic position, feared posterior instability of the talus would not appear to be an indication for internal fixation of posterior malleolar fractures.

Fracture Identification

In a sports medicine center, we prospectively evaluated the Ottawa Ankle Rules over 1 year for their ability to identify clinically significant ankle and midfoot fractures and to reduce the need for radiography. We also developed a modification to improve specificity for malleolar fracture identification. Patients with acute ankle injuries ( 10 days old) had the rules applied and then had radiographs taken. Sensitivity, specificity, and the potential reduction in the use of radiography were calculated for the Ottawa Ankle Rules in 132 patients and for the new “Buffalo” rule in 78 of these patients. There were 11 clinically significant fractures (fracture rate, 8.3% per year). In these 132 patients, the Ottawa Ankle Rules would have reduced the need for radiography by 34%, without any fractures being missed (sensitivity 100%, specificity 37%). In 78 patients, the specificity for malleolar fracture for the new rule was significantly greater than that of the Ottawa Ankle Rules malleolar rule (59% versus 42%), sensitivity remained 100%, and the potential reduction in the need for radiography (54%) was significantly greater. The Ottawa Ankle Rules could significantly reduce the need for radiography in patients with acute ankle and midfoot injuries in this setting without missing clinically significant fractures. The Buffalo modification could improve specificity for malleolar fractures without sacrificing sensitivity and could significantly reduce the need for radiography.

Posterior Malleolus

Objective: This study proposes a new classification of posterolateral malleolar fractures and a treatment algorithm. Methods: We divided the posterolateral malleolus, which we considered as the posterior malleolus, from the posteromedial one, which we considered as being part of the medial malleolus fracture. The experience with 77 patients treated from February 2017 to February 2020 was assessed. All of them were assessed by frontal and profile radiographies and computed tomography (CT). Among the parameters to classify these fractures, we believe the most determining ones are fracture size, followed by presence of fracture displacement. Results: Fractures were divided into those whose posterior fragment was 25% smaller than the tibial joint surface and those that compromised more than 25% of this joint. The first group underwent syndesmotic opening and was subclassified into 1A (stable fractures), which do not require surgical treatment, and 1B (unstable), which require syndesmotic stabilization. The second group, which comprised the larger fractures, was subclassified into 2 A (non-displaced fractures, or with a displacement below 2 mm), which underwent percutaneous osteosynthesis, 2B (displaced fractures), and 2C (comminuted fractures), which underwent open reduction and internal fixation using a posterior approach. Conclusion: The classifications published so far are anatomic or descriptive, but none of them proposes a therapeutic algorithm for each type of fracture. We believe it will be helpful for its interpretation and decision-making on the need to perform a posterior approach, prioritizing the anatomical reduction of the joint fragment and resolution of syndesmotic instability linked to each fracture pattern using the most simple and effective method.
