Clinical Outcome of Femoral Neck System Versus Cannulated Compression Screws for Fixation of Femoral Neck Fracture in Younger Patients

Abstract

Background: The clinical outcome of a new fixation device (femoral neck system, FNS) for femoral neck fractures remains unclear. The main purpose of this study was to evaluate two different internal fixation methods for the treatment of femoral neck fractures in patients aged under 60 years. Methods: We retrospectively studied patients who underwent internal fixation surgery in our hospital for femoral neck fractures between January 2017 and January 2020. Cannulated compression screws (CCS) and FNS groups were divided according to different internal fixation methods. General data (such as sex, age, body mass index, type of fracture) of all patients were collected, and joint function was evaluated using the Harris score before and 1 year after surgery. We recorded related surgical complications, including femoral head necrosis, nonunion, and femoral neck shortening. Results: There were no significant differences in age, sex, or body mass index between the two groups. There was no statistical difference in Harris scores between the two groups before surgery. Patients who underwent FNS treatment had longer surgery time (79.75±26.35 min vs. 64.58±18.56 min, p=0.031) and more blood loss (69.45±50.47 mL vs. 23.71±28.13 mL, p<0.001). The degree of femoral neck shortening in the FNS group was significantly lower than that in the CCS group. Regarding postoperative complications, there was no statistical difference in the incidence of femoral head necrosis and fracture nonunion between the two groups.Conclusion: Patients younger than 60 with femoral neck fractures can obtain satisfactory clinical results with CCS or FNS treatment. FNS has excellent biomechanical properties and shows significantly higher overall construct stability.

[Retracted] Clinical Effect of Open Reduction and Internal Fixation for Femoral Neck Fracture in Young Adults and Related Factors of Femoral Head Necrosis

“…In an analysis of the comparative study of minimally invasive plate fixation reduction surgery with fractures, it was found that the effect of minimally invasive plate fixation reduction surgery was better than that of open reduction and internal fixation and the incidence of complications was lower [7]. The treatment effect of minimally invasive internal fixation on patients with distal tibia fractures is better than that of open reduction and internal fixation with a plate [8], and closed reduction and internal fixation for supracondylar fractures of the humerus have a good surgical effect and can significantly reduce the number of children with family burden [9]. The tibia plateau is an important loading structure of the knee joint, and its fractures are mostly caused by violence directly or indirectly.…”

Comparison of Femoral Neck System Versus Dynamic Hip System Blade for the Treatment of Femoral Neck Fracture in Young Patients: A Retrospective Study

“…In a study with an average follow-up of 27 months, DHSb showed better clinical outcomes than cannulated compression screws in preventing femoral neck shortening, screw migration, and cut-out; however, there was no signi cant difference in postoperative fracture union [17]. In addition, Hu et al reported that only the occurrence of femoral neck shortening was signi cantly less with the FNS than with cannulated compression screws; no statistical difference was observed in femoral head necrosis and fracture nonunion between the two groups [9]. However, to date, no clinical trial has investigated the clinical outcomes of FNS and DHSb in young patients.…”

“…A biomechanical evaluation of human cadaveric femora supported the FNS as an effective alternative to DHS and cannulated screws for the treatment of FNF [8]. Another clinical study reported that patients with FNF who received FNS treatment had better clinical outcomes than those treated with cannulated compression screws [9]. However, to our knowledge, no study has compared the clinical outcomes of FNS and DHSb in young patients with FNF.…”

Comparison of Femoral Neck System versus Cannulated Screws for Treatment of Femoral Neck Fractures: A Systematic Review and Meta-Analysis

“…It is more stable than CS in biomechanical studies [11]. Some studies have found that FNS promotes fracture healing and reduces operative time and postoperative complications [13][14][15][16][17] . However, other studies have found that the treatment with FNS did not show signi cant differences in these aspects compared with CS [18][19][20].…”
