ObjectiveTo study the clinical effect of the proximal femoral anatomical locking plate in the treatment of ipsilateral femoral shaft and neck fractures.Methods A retrospective study was done on 10 patients with ipsilateral femoral shaft and neck fractures treated with proximal femoral anatomical locking plate in our hospital from February 2009 to February 2011.After treatment,the outcome was assessed regularly by fracture union as was seen on serial radiographs and clinical function was estimated by Friedman and Vyman System.ResultsAll patients were followed up for 6-24 months ( average 16 months).All the fractures were healed within 2.5-4 months (average 3 months) in the femoral shaft and within 4-9 months (average 6 months) in the neck,respectively.According to Friedman and Vyman System,the overall clinical result was good in eight patients and fair in two,with excellent rate of 80% (8/10).No osteonecrosis of the femoral head and fixation failure were observed during the followup. Conclusion Proximal femoral anatomical locking plate internal fixation is an effective treatment method for ipsilateral femoral shaft and neck fractures.
