ObjectivesThis study compared results of aggressive and nonaggressive debridement protocols for the treatment of high-energy, open supracondylar femur fractures after the primary procedure, with respect to the requirement for secondary bone grafting procedures, and deep infection.DesignRetrospective review.SettingLevel I and level II trauma centers.Patients/ParticipantsTwenty-nine consecutive patients with high-grade, open (Gustilo types II and III) supracondylar femur fractures (OTA/AO 33A and C) treated with debridement and locked plating.InterventionSurgeons at 2 different level I trauma centers had different debridement protocols for open supracondylar femur fractures. One center used a more aggressive (MA) protocol in their patients (n = 17) that included removal of all devitalized bone and placement of antibiotic cement spacers to fill large segmental defects. The other center used a less aggressive (LA) protocol in their patients (n = 12) that included debridement of grossly contaminated bone with retention of other bone fragments and no use of antibiotic cement spacers. All other aspects of the treatment protocol at the 2 centers were similar: definitive fixation with locked plates in all cases, IV antibiotics were used until definitive wound closure, and weight bearing was advanced upon clinical and radiographic evidence of fracture healing.Main Outcome MeasurementsHealing after the primary procedure, requirement for secondary bone grafting procedures, and the presence of deep infection.ResultsDemographics were similar between included patients at each center with regard to age, gender, rate of open fractures, open fracture classification, mechanism, and smoking (P > 0.05). Patients at the MA center were more often diabetic (P < 0.05). Cement spacers to fill segmental defects were used more often after MA debridement (35% vs. 0%, P < 0.006), and more patients had a plan for staged bone grafting after MA debridement (71% vs. 8%, P < 0.006). Healing after the index fixation procedure occurred more often after LA debridement (92% vs. 35%, P < 0.003). There was no difference in infection rate between the 2 protocols: 25% with the LA protocol and 18% with the MA protocol (P = 0.63). All patients in both groups eventually healed and were without evidence of infection at an average of 1.8 years of follow-up.ConclusionsThe degree to which bone should be debrided after a high-energy, high-grade, open supracondylar femur fracture is a matter of surgeon judgment and falls along a continuous spectrum. Based on the results of the current study, the theoretic trade-off between infection risk and osseous healing potential seems to favor an LA approach toward bone debridement in the initial treatment.Level Of EvidenceTherapeutic level III.
