    AbstractTwenty-six comminuted distal femur fractures treated with a lateral condylar buttress plate were followed up until fracture union or implant revision (mean follow-up, 26 months). Mean postoperative angle (medial distal femoral angle immediately after surgery) was 96 degrees, and mean final angle (angle at fracture healing or implant revision) was 91 degrees (P = .06). Distal femoral angle decreased 5 degrees or less in 15 patients, 6 degrees to 10 degrees in 8 patients, and more than 10 degrees in 3 patients. Final distal femoral angle was 90 degrees or less in 13 of the 26 fractures: 38% of these 13 fractures required reconstruction for nonunion, malunion, or knee arthrosis. The lateral condylar buttress plate, which is not a fixed-angle device, allowed more than 5 degrees of varus collapse to occur in 42% of the comminuted distal femur fractures.
