Purpose: We aimed to evaluate the outcome of fixation with cannulated screws for valgus impacted femoral neck fractures in patients over 70 years of age.
Materials and Methods: We reviewed the outcome in 33 patients older than 70 years with valgus impacted femoral neck fractures who were treated with cannulated screws fixation from May 2007 to December 2010. These patients were followed for at least a year. We assessed the fixation failure rate, body mass index (BMI), bone mineral density (BMD) of proximal femur, distance between screw tip and joint, number of screws and time from fracture to operation.
Results: We identified six patients (18.2%) with failure. Two patients with subtrochanteric fractures through the screw insertion site and another patient with osteonecrosis were excluded from the fixation failure group. No difference was found in age, BMI, BMD of proximal femur, distance between screw tip and joint, number of screws and time from fracture to operation between failure and non-failure groups.
Conclusion: The failure rate of cannualted screw fixation for valgus impacted femoral neck fractures in the elderly patients was not low. Risk of failure should be considered in the management of these patients and accurate assessment for fracture type should be performed using computed tomogram and clinical evaluation.
