Objectives: To compare the clinical efcacy of a femoral neck system (FNS) and cannulated screws (CS) in the treatment of femoral neck fracture in young adults.

Methods: Data from 69 young adults, who were admitted for femoral neck fracture between March 2018 and June 2020, were retrospectively analyzed. Patients were divided into two groups according to surgical method: FNS and CS. The number of intraoperative fuoroscopies, operative duration, length of hospital stay, fracture healing time, Harris score of hip function, excellent and good rate of hip function, and postoperative complications (infection, cut out the internal fxation, nail withdrawal, and femoral neck shortening) were compared between the two groups. Hip joint function was evaluated using the Harris Hip Scoring system.

Results: All 69 patients had satisfactory reduction and were followed up for 12–24 months, with a mean follow-up of 16.91±3.01 months. Mean time to fracture healing was13.82±1.59 and 14.03±1.78 weeks in the FNS and CS groups, respectively. There was a statistical diference in the number of intraoperative fuoroscopies between the 2 groups (P=0.000). There were no signifcant diferences, in operation duration, hospital length of stay, fracture healing time, complications, Harris Hip Score for hip function and excellent and good rate between the two groups (P>0.05). The incidence of complications was 6.1%(2/33) in the FNS group lower than 25%(9/36) in the CS group, a diference that was statistically signifcant (P=0.032). At the last follow-up, the Harris Hip Score of the hip joint in the FNS group was 90.42±4.82and 88.44±5.91 in the CS group.

Conclusion: Both treatment methods resulted in higher rates of fracture healing and excellent hip function. Compared with CS, the FNS reduced the number of intraoperative fuoroscopies, radiation exposure to medical staf and patients, and short-term complications including femoral neck shortening and bone nonunion.
