Surgical Site Complications in Open Pronation-Abduction Ankle Fracture-Dislocations With Medial Tension Failure Wounds.

OBJECTIVES

To examine the incidence of surgical site complications associated with pronation-abduction ankle fracture-dislocations with an open medial tension wound.

DESIGN

Retrospective case series.

SETTING

Accredited Level-1 trauma center.

PATIENTS/

PARTICIPANTS

Forty-eight open pronation-abduction ankle fracture-dislocations with medial tension failure wounds treated at our institution from 2014 to 2016.

INTERVENTION: Immediate irrigation and debridement along with surgical stabilization of open ankle fracture-dislocation.

MAIN OUTCOME MEASURES: The primary outcome measure was deep surgical site infection. Secondary outcome measures included other surgical site complications and adverse radiographic events.

RESULTS

A total of 5 patients (10.4%) developed a deep surgical site infection requiring additional surgical debridement. One of the patients with a deep surgical site infection required a below-knee amputation as a result of sepsis. Adverse radiographic outcomes included 3 fibular nonunions (6.3%), 3 implant failures related to syndesmotic fixations (6.3%), one periimplant fracture (2.1%), and postoperative collapse of the tibial plafond in 3 patients (6.3%).

CONCLUSIONS

Open pronation-abduction ankle fracture-dislocations with medial tension failure wounds remain a challenging and potentially devastating injury. Our study suggests that with appropriate surgical debridement, early stabilization, and primary wound closure, acceptable outcomes with a relatively low risk of surgical site complications can be achieved.
