Background. The treatment of vertical femoral neck fractures in young patients remains a challenge. This study is aimed at comparing ordinary cannulated compression screw (OCCS) and double-head cannulated compression screw (DhCCS) fixation in vertical femoral neck fractures both clinically and biomechanically. Materials and Methods. Clinically, the radiographs of 81 patients with Pauwel’s III femoral neck fractures, including 54 fractures fixed with three parallel OCCSs and 27 fractures fixed with three parallel DhCCSs, were reviewed retrospectively. Complications consisting of fixation failure (screw loosening, obvious fracture displacement, varus deformity, or femoral neck shortening), bony nonunion, and avascular necrosis (AVN) were determined. Biomechanically, twenty synthetic femur models of vertical femoral fractures with an 80° Pauwel’s angle were divided into two groups and subsequently fixed with three parallel OCCSs or DhCCSs. All specimens were tested for axial stiffness, load to 5 mm displacement, and a maximum load to failure with a loading rate of 2 mm/min. Results. Clinically, 22 fractures in the OCCS group experienced fixation failure, including 19 screw loosening, 18 femoral neck shortening, 14 varus deformities, and 8 obvious fracture displacements, whereas only 4 fractures experienced fixation failure in the DhCCS group, including 3 screw loosening, 3 femoral neck shortening, 3 varus deformities, and 1 obvious fracture displacement. Additionally, 11 fractures in the OCCS group exhibited nonunion, whereas only 3 in the DhCCS group exhibited nonunion. Nine fractures with AVN were noted in the OCCS group, whereas only 1 was observed in the DhCCS group. Biomechanically, the axial stiffness of the DhCCS group was greater than that of the OCCS group ( 154.9 ± 6.81 vs. 128.1 ± 7.41  N/mm), and the load to 5 mm displacement was also significantly greater in the DhCCS group ( 646.1 ± 25.87 vs. 475.8 ± 21.46  N). Moreover, the maximum load to failure in the DhCCS group exhibited significant advantages compared with that of the OCCS group ( 1148 ± 39.47 vs. 795.9 ± 51.39  N). Conclusion. Our results suggested that using three DhCCSs improved the outcome of vertical femoral neck fractures compared to three OCCSs, offering a new choice for the treatment of femoral neck fracture.

ABSTRACT Objective: To evaluate the rate of deviation in the lateral radiographic incidence in patients with femoral neck fracture classified as non-diverted in the anteroposterior view (Garden I and II). Methods: Nineteen selected patients with femoral neck fractures classified as Garden I and II were retrospectively evaluated, estimating the degree of deviation in the lateral view. Results: Fifteen cases (79%) presented deviations in lateral view, with a mean of 18.6 degrees (±15.5). Conclusion: Most fractures of the femoral neck classified as Garden I and II present some degree of posterior deviation in the X-ray lateral view. Level of Evidence III, Retrospective Comparative Study.

Abstract Background: Femoral neck fractures are one of the problems in orthopedic treatment. The prognosis is uncertain. Currently, there is no one internal fixation for the treatment of femoral neck fractures that shows superiority over other internal fixations. Therefore, the internal fixation system needs to be further explored. The aim of this study was to compare clinical outcomes of femoral neck dynamic compression locking system （DCLS）and multiple cannulated compression screws（MCCS） in the treatment of femoral neck fractures.Methods: A prospective analysis of 54 cases of femoral neck fractures treated with either a DCLS (n=28) or MCCS (n=26) was conducted between December 2015 and November 2017 in authors’ hospitals. The perioperative and postoperative parameters of the two groups were recorded and evaluated.Results: Fifty-four patients were followed up for 24-47 months. The etiology was caused by a fall. There was no significant difference in follow-up time, operation time, incision length, surgical blood loss, the incidence of perioperative and postoperative healing complications, and mobility in the two groups (P> 0.05). The Harris score, fracture healing time, femoral neck shortening, partial weight-bearing time and complete weight-bearing time were significantly better in the DCLS group than in the MCCS group (P< 0.05). The fracture healing rate in the DCLS group was higher than that in the MCCS group.Conclusion: The DCLS and MCCS might be equally effective in terms of operation time, incision length, surgical blood loss, the incidence of perioperative and postoperative healing complications, and mobility in the treatment of femoral neck fractures. However, the DCLS is superior to the MCCS in Harris score, fracture healing time, femoral neck shortening, weight-bearing time and fracture healing rate. So, DCLS deserves further study.
