Abstract: Objective To evaluate the efficacy of percutaneous plate fixation with LCP (locking compression plate) in the treatment of distal femoral fractures. Methods From January 2011 to November 2015, 18 cases of distal femoral fractures were treated with LCP transdermal plate technique. The fractures of intra-articular were only reset under the incision of the joint, and some of them needed to be fixed with the tension for anatomical reduction of the articular surface. The femoral supracondylar fracture was treated with MIPPO (minimally invasive plate percutaneous osteosynthesis) technique and fixed with the plate. Results All cases were followed up for 10~21 (15.5±5.2) months. Fractures were healed at an average time of (14.5±2.2) weeks, and the average load-bearing time was (18.5±3.2) weeks. All the incision were healed by first intention and fracture reduction was satisfied. No postoperative infection, internal fixation fracture, nonunion, deep vein thrombosis, limb shortening, knee varus and other complications were observed. The knee function was graded according to the Neer score: excellent in 13 cases, good in 5 cases, excellent and good rate was 100%. The knee join movement degrees: A3 fracture was 124 °~135 ° (130 ° ±6 ° ), C2 fracture was 85 °~135 ° (111 ° ±25 ° ), C3 fracture was 84 ° . Conclusion Percutaneous implantation of plate technique combined with domestic LCP is a safe and effective method for the treatment of distal femoral fractures. It can meet the clinical needs of primary hospital.
