    Author: Chen AT, Vallier HA.
    Journal: Injury; 2016 Mar; 47(3):742-7. PubMed ID: 26776462.
    Abstract:
    INTRODUCTION: Isolated fractures of the lower extremity are relatively common injuries while multifocal injuries resulting from high-energy trauma are less frequently encountered. Our objectives are to characterise patients who sustained multiple noncontiguous fractures and open fractures of the lower extremity, report the incidence of major complications, and identify factors that may contribute to complications and unplanned re-operations. PATIENTS AND METHODS: A retrospective review of patients was performed at a Level 1 trauma centre from 2000 to 2013. Patients who sustained two or more noncontiguous operative fractures in an ipsilateral lower extremity, with at least one open fracture were included. Noncontiguous was defined as fractures in the same lower limb that were not in continuity on preoperative radiographs or intra-operatively. Demographic, injury characteristics, and hospitalisation data were collected. Primary outcomes included non-union, deep infection, and the need for unplanned surgeries. RESULTS: 257 patients sustained a total of 876 lower extremity fractures with an average of 1.7 open and 2.7 operative fractures in the qualifying limb. Ninety-nine patients (38.5%) sustained bilateral lower extremity injuries. Following their initial stay, 22.6% of patients had planned procedures (definitive fixation, skin, or planned bone grafting). Nearly half (45.9%) required one or more unplanned re-operation. Complications included deep infections (19.5%), non-unions (19.5%), and mal-unions (2.7%). 17.5% of the patients had at least one procedure for removal of painful implants. A deep infection was predictive of having a non-union (odds ratio, OR 7.5). The presence of a Gustilo-type IIIB/IIIC (OR 24.6/16.0) fracture was predictive of having a deep infection. After excluding painful implant removal, a type IIIB fracture was associated with an unplanned procedure (OR 13.8). CONCLUSIONS: Patients with multiple non-contiguous lower extremity injuries associated with open fractures can expect complications including non-unions, deep infections, and painful implants. Nearly half of the patients will need further operative treatment.
