Background: Ankle sprains occur frequently in both athletes and the general population. The social and economic consequences can be significant. In an effort to understand the injury, dynamic and static structures around the ankle have been investigated in detail, but anatomical factors predisposing to lateral ankle instability have not been fully clarified. The aim of this study was to radiologically investigate the relationship between bony variations of the distal tibiofibular joint and arthroscopically proven ankle instability.
Methods: Fifty patients with arthroscopically proven ankle instability and 50 patients without instability were included in this study. Measurements were obtained from a magnetic resonance imaging (MRI) section 1 cm proximal to the tibiotalar joint; distal tibiofibular joint anterior facet length (), posterior facet length (), angle between the anterior and posterior facets (), fibular notch depth (), tibia thickness (), and fibula thickness () was measured.
Results: It was found that instability was more frequent when the length of ( < .001) and ( < .001) were shorter. In addition, when value of / and e/f were evaluated, it was observed that the number of individuals who had instability increased as the ratio became smaller ( < .016-.020, respectively). Pearson correlation analysis indicated strong negative correlation between the values of - and instability ( = -0.348, < .001, and = -0.328, = .001; respectively).
Conclusion: Lateral ankle sprains are common, and a clear understanding of the relevant structures and clinical function of the ankle complex should extend beyond the talocrural joint. This study demonstrated that the presence of narrow anterior facet () and thinner tibia () were strongly correlated with lateral ankle instability.
Level Of Evidence: Level III, retrospective case control study.

Background And Purpose: Accurate quantification of bony malalignment within the ankle syndesmosis is crucial in diagnosing syndesmotic instability, especially when subtle. While three-dimensional (3D) measurement techniques using weight-bearing computed tomography (WBCT) have gained popularity, normative bilateral comparative data still need to be established. This study aimed to identify the side-to-side variations and gender differences in the syndesmotic area and volume among individuals without syndesmotic injury using WBCT.

Background: Managing large bone defects remains a significant clinical problem. We enhanced the osteogenic activity of the induced membrane (IM) by incorporating bone marrow fluid, leading to spontaneous osteogenesis (SO). We aimed to explore the application of this method in tibiofibular fusion (TFF) for reconstructing segmental tibial defects.

Supination-external rotation (SER) type IV ankle fractures, as classified by Lauge-Hansen (L-H), are highly unstable due to frequent injuries of the deltoid and distal tibiofibular ligaments. These fractures typically require open reduction and internal fixation (ORIF), followed by prolonged immobilization and delayed weight bearing. Such protocols often result in extended recovery periods, delaying the return to competitive sports.

Background: The distal tibiofibular syndesmosis (DTS) is crucial for maintaining ankle stability and distributing stress in the ankle joint. However, the in vivo kinematics of the DTS during high-impact activities remain unknown. This study aims to explore these kinematics and investigate the influence of additional trunk load using a high-speed dual fluoroscopy imaging system (DFIS).

Syndesmotic instability or malreduction is an independent risk factor for an impaired patient-rated outcome. If a syndesmotic injury is suspected, a stepwise diagnostic approach including plane radiographs, MRI, and bilateral stress radiographs should be conducted to differentiate stable from latent unstable and frank diastasis cases. The basic requirement for any surgical treatment approach is a stable and anatomically reduced distal tibio-fibula joint.
