Summary
Fragment-specific plating for trimalleolar ankle fractures significantly improves patient-reported outcomes, particularly in pain and activity levels, compared to conventional methods. Further research is recommended for standardized treatment protocols.
Area of Science:
- Orthopaedic Surgery
- Traumatology
- Biomechanics
Background:
- Trimalleolar ankle fractures are unstable injuries often resulting from rotational forces.
- Historically, posterior malleolar fractures had poorer outcomes due to a lack of specific classification.
- Advancements in understanding fracture mechanisms allow for fragment-specific fixation strategies.
Purpose of the Study:
- To compare post-operative functional outcomes of fragment-specific plating versus conventional plating for trimalleolar ankle fractures.
- To evaluate patient-reported outcome measures (PROMs) at 12 months post-surgery.
Main Methods:
- Retrospective cohort study of patients with trimalleolar ankle fractures requiring surgical fixation.
- Fracture classification and surgical correction using computed tomography (CT) imaging, fragment-specific, or conventional plating.
- Functional outcomes assessed using the Foot and Ankle Disability Index (FADI) and Manchester-Oxford Foot Questionnaire (MOXFQ).
Main Results:
- 22 matched pairs of patients were analyzed.
- Statistically significant improvements were observed in the activity and pain subscales of the FADI (P > .05) with fragment-specific plating.
- No significant differences were found in the MOXFQ scores between the two groups.
Conclusions:
- Fragment-specific plating of the posterior malleolar component in trimalleolar ankle fractures leads to superior functional outcomes regarding pain and activity, as measured by the FADI.
- Larger studies with longer follow-up are necessary to validate these findings and inform standardized treatment.
- Level of Evidence: Level 2.

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
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...

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
