Negative prognostic factors in surgical treatment for trimalleolar fractures
- 4 Downloads
Trimalleolar fractures are a common injury of the ankle that require surgical treatment to obtain an anatomic reduction of both malleoli and stabilization of the syndesmosis. This study aims to report the outcomes of surgical treatment for trimalleolar fractures, identifying the risk factors determining a worse result.
Materials and methods
Between January 2013 and December 2016, 48 patients with trimalleolar fracture treated with open reduction and internal fixation were retrospectively analyzed. The mean age was 44.69 years, and average body mass index (BMI) was 29.04. According to the Danis–Weber classification, 30 (62.5%) fractures were type B and 18 (37.5%) were type C. Clinical and radiographic evaluations at 3, 6, and 12 months were assessed. The functional results of Visual Analogue Staircases and Olerud–Molander (O&M) ankle score were reported.
No significant difference was found among the size of the PM in patients with and without ankle dislocation (p = 0.364). Therefore, there is no correlation between the size of the posterior fragment and the ankle dislocation and the size of the posterior malleolus and syndesmosis stability (p = 0.328). Age over 61 years, BMI > 40, ASA > 1, type C fracture, and fracture dislocation were considered as negative prognostic fractures.
Surgical treatment for trimalleolar fractures needs accurate preoperative planning. Age over 61 years, BMI > 40, ASA > 1, type C fracture, and fracture dislocation were considered as negative prognostic fractures.
