Open Distal Femur Fractures Treated with Bone Cement Intramedullary Support Combined with Locked Plate Fixation.
Alternative Therapies in Health and Medicine 2024 Februrary 10
OBJECTIVE: The objective of this study was to assess the short-term clinical efficacy of the short-term clinical efficacy of bone cement intramedullary support combined with locked plate fixation in the treatment of such fractures.
METHODS: A retrospective study including 21 patients was reviewed at an urban level one trauma center. There were 17 males and 4 females, with a mean age of 33.9 years. Gustilo grade was II (12 cases), III-A (6 cases), III-B (2 cases), and III-C (1 case). Two fractures were AO-OTA type 33A3, 9 cases were type 33C2, and 10 cases were type 33C3. After the first stage debridement and temporary external fixation, all patients received bone cement intramedullary support combined with locked plate fixation through an anterolateral incision at the second stage.. The perioperative complications, need for bone graft, alignment, and radiographic union were recorded. At 1-year follow-up, the range of knee motion was recorded, and functional results were evaluated by the Hospital for Special Surgery (HSS) knee score.
RESULTS: All 21 patients were followed up for 12-36 months, with an average of 18.7 months. 1 case had superficial wound infection, and 2 cases had partial skin edge necrosis of the original open wound. After symptomatic dressing changes, they all healed well. 4 cases had autogenous bone grafting. 18 patients (85.7%) achieved radiographic union, with a mean union time of 6.2 months. Two patients underwent secondary operation 9 months after surgery due to nonunion and finally united after autologous bone grafting. One patient developed a deep infection 8 months after surgery and was successfully treated with Masquelet technique. Finally, bone union was achieved 7 months after surgery. The alignment was good in 17 patients (81.0%). No deep infection or hardware failure occurred during 1-year follow-up. The average range of knee extension and flexion was 5.2 ° and 106.8 °, respectively. The HSS score averaged 83.6.
CONCLUSIONS: Bone cement intramedullary support combined with locked plate fixation was an effective treatment modality of open distal femur fractures with high union rate, low complication, adequate alignment and satisfactory functional outcomes.
