Table 1 Trajectory angles in each of the CT-based posterior malleolar fracture types

From: Preoperative planning and surgical technique for optimizing internal fixation of posterior malleolar fractures: CT versus standard radiographs

Fracture typeNumber (%) of casesMean TA (range) (°)
Postero-medial4 (4.7%)28 (25–31)
Postero-central20 (23.5%)7 (2–13)
Postero-lateral61 (71.8%)21 (17–26)
  1. For “postero-medial” fragments, the trajectory angle line is typically subtended from a starting point medial to the AP central line. For “postero-lateral” and “postero-central” fragments, the trajectory angle line is typically subtended from a starting point lateral to the AP central line
