Clean FRCS notes with inline figures
Ankle Xray of mortise view of skeletally immature patient
•Fracture over distal tibia epiphysis on lateral side, fibula no fracture
•Tillaux fracture
•Which is an SH 3 Fracture
•Transitional fracture
•CT to delineate # pattern and see displacement
•Displacement <2mm conservative with long leg cast (for rotational control. Foot IR + direct anterior pressure + knee 30 deg flexion) x 4/52 then short leg cast x 2/52 (post cast CT to make sure no displacement)
•If displacement >2mm go for CR +/- OR via AL approach + stable fixation (percutaneous screw) (can be transphyseal as approaching skeletal maturity)
•Near end of growth, older than triplane ~ 12-14
•ER
•caused by an avulsion of the anterior inferior tibiofibular ligament
•Lack of fracture component in sagittal plane distinguish this fracture from triplane injury
