| Objective To analyze the efficacy of the biplane double-supported screw in stability optimization of femoral neck fracture comparing with the traditional cannulated screws.Methods A total of 58 patients suffering femoral neck fractures treated with closed reduction and internal fixation with biplane double-supported screw fixation and traditional cannulated screws from June 2014 to June 2018 in Taicang Affiliated Hospital of Suzhou University were retrospectively reviewed. Thirty-one cases treated with three cannulated screws in aninverted triangle configuration, while the rest 27 cases treated with biplane double-supported screw fixation. We compared the efficacy of these two groups, including the fracture nonunion, femoral neck shortening, necrosis of femoral head and the Harris hip score.Results All the patients were followed up for 24-43 months, with an average of (26.3±3.3) months. In the group treated with biplane double-supported screw fixation, there were 6 patients with femoral neck shortening ≥5 mm, and 4 cases of fracture nonunion, 2 cases of femoral head necrosis,. The average Harris hip score after surgery was (85.74±7.06) points. In another group, there were 16 cases of femoral neck shortening≥5 mm, 5 cases of fracture nonunion, and 9 cases of femoral head necrosis, . The average Harris hip score was (82.03±6.19) points after operation. There were statistically significant differences in femoral neck shortening, femoral head necrosis and Harris hip score between the two groups (P<0.05).Conclusion The group treated with biplane double-supported screw fixation achieved better clinical efficacy. The biplane double-supported screw fixation limited the sliding compression in order to reduce the occurrence of femoral neck shortening through the special configuration in patients achieved good and excellent reduction. The stability was optimized and the patients had better recovery of hip function. |
