[TREATMENT OF PRONATION EXTERNAL ROTATION ANKLE FRACTURE COMBINED WITH SEPARATION OF DISTAL TIBIOFIBULAR SYNDESMOSIS].

Objective: To evaluate the difference between using and not using syndesmotic screw to treat pronation external rotation (PER) ankle fracture combined with separation of distal tibiofibular syndesmosis.

Methods: Between April 2011 and October 2014, 46 cases of PER ankle fracture combined with separation of distal tibiofibular syndesmosis were treated, and syndesmotic screw was used in 24 cases (fixation group) and syndesmotic screw was not used in 22 cases (non-fixation group). There was no significant difference in gender, age, weight, cause of injury, side, injury to operation time, and fracture type between 2 groups (>0.
