Early Protected Weightbearing After Open Reduction Internal Fixation of Ankle Fractures With Trans-syndesmotic Screws

Traditional postoperative care after open reduction internal fixation (ORIF) of unstable ankle fractures with syndesmotic instability includes non-weightbearing for 6 to 8 weeks. However, prolonged non-weightbearing may be detrimental. The goal of this case series was to assess the outcomes of early protected weightbearing after operative treatment of acute ankle fractures with syndesmotic instability requiring screw stabilization. Fifty-eight consecutive patients, treated from January 2006 to January 2013, met the inclusion criteria with a minimum follow up of 1 year. Electronic medical records and radiographs were reviewed for patient and surgical characteristics, postoperative complications, and maintenance of reduction. Patients initiated walking at an average of 10 days (range 1 to 15) postoperatively. Surgical treatment consisted of operative reduction with standard fixation devices and 1 or 2 trans-syndesmotic screws that purchased 4 cortices. All 58 patients maintained correction after surgery when allowed to weightbear early in the postoperative recovery. Five complications (8.6%) occurred in the 58 patients, which included 3 superficial infections (5.2%) and 2 cases (3.4%) of neuritis. The maintenance of reduction and low complication rate in this study support the option of early protected weightbearing after ankle fracture ORIF with trans-syndesmotic fixation.
