RESUMEN
The incidences of femoral neck fracture are increasing. According to its high complication and lack of enough study about this subject in our country, we decided to perform this study. In this cross-sectional observational study, we evaluated 80 patients with femoral neck fracture who referred to Hazrat-e-Rassol hospital and underwent Internal Fixation from 1383-85. The patients were followed at least one year after surgery. [15%] non-union, 3 patients [3.75%] infection, and 28 patients [35%] pain and claudication. The co: 29 patients [36.3%] had at least one complication: 19 patients a vascular necrosis [23.8%] AVN, 12 patients mplication rate was lower in base fractures than subcapital and transcervical. [p=0.019] In patients without displacement, there was not any complication but 29 of 65 patients with displacement had complication [p=0.001]. The rate of complication became higher when the quality of reduction and fixation was poor [p=0.000]. According to results of this and previous studies, we recommend more attention about the quality of reduction and fixation. Also because the rate of complication was high in group with displacement, the hip arthroplasty should be considered in these patients and patients above 65-year-old with displace fracture
