Clinical outcome of femoral neck system for fixation of femo
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.

Researchers retrospectively studied patients who underwent internal fixation surgery. Cannulated compression screws (CCS) and femoral neck system -FNS groups were divided according to different internal fixation methods. General data (such as sex, age, body mass index, type of fracture) of all patient Femoral neck shorteningts were collected, and joint function was evaluated using the Harris Hip Score (HHS) before and 1 year after surgery. Researchers recorded related surgical complications, including femoral head necrosis, nonunion, and femoral neck shortening.

--There were no significant differences in age, sex, or body mass index between the two groups. There was no statistical difference in HHSs between the two groups before surgery.

--Patients who underwent FNS treatment had longer surgery time and more blood loss.

--The degree of femoral neck shortening in the FNS group was significantly lower than that in the CCS group (10.0% vs 37.5%).

--Regarding postoperative complications, there was no statistical difference in the incidence of femoral head necrosis and fracture nonunion between the two groups.

Conclusively, 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.
