ObjectiveTo evaluate and compare the outcome of two kinds of diameter hollow screws for the treatment of femoral neck fractures.MethodsFrom June 2008 to June 2013, 117 patients with femoral neck fractures were treated by closed reduction and hollow screws fixation. Among them,48 patients were fixed by 6.5 mm screw including 30 males and 18 females with an average age of (45.61 ± 11.99) years old ranging from 19 to 60 years old, involving 17 cases in Garden I/II and 31 cases in Garden III/IV; 69 patients were fixed by 8.0 mm screw including 40 males and 29 females with an average age of (45.17 ± 9.95) years old ranging from 18 to 60 years old, involving 31 cases in Garden I/II and 38 cases in Garden III/IV. The general information, operative time, hospital stay time, reduction quality, diameter of femoral head and neck, fracture healing time, the rate of fracture healing, postoperative complications were recorded and evaluated. Harris scoring was used to evaluate the hip joint function.ResultsAll patients were followed up for 19.6 months (18 to 24 months). The difference of operative time, duration of hospitalization, quality of reduction were not statistically significant (P > 0.05). There was no difference between two groups about the average diameter of the femoral head and neck, the fracture healing time, the rate of healing and the postoperative complications (P > 0.05). There were no difference between two groups about Harris scale. There were significant difference between Garden III/IV and I /II (P > 0.05).ConclusionClosed reduction and internal fixation with hollow screw in treating the young adult patients with femoral neck fracture is the first choice, both different diameters hollow screws could meet the requirements of fixation of femoral neck fracture, and not affect on fracture healing time and postoperative complications.
