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 type

Number (%) of cases

Mean TA (range) (°)

Postero-medial

4 (4.7%)

28 (25–31)

Postero-central

20 (23.5%)

7 (2–13)

Postero-lateral

61 (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
