Therapeutic effects of femoral neck system internal fixation on femoral neck fracture

We aimed to compare the therapeutic effects of femoral neck system (FNS) internal fixation and other internal fixation methods on patients with femoral neck fracture. Thirty patients treated from January 2019 to January 2021 were assigned into control and observation groups. Intraoperative blood loss was less, fluoroscopy frequency was lower, postoperative off-bed ambulation time and length of hospital stay were shorter, and postoperative complication rate was lower in observation group than those in control group (P<0.05). At 1-3 d after operation, the observation group had significantly decreased pain score and levels of C-reactive protein and interleukin-6 compared with the control group (P<0.05). At 3 and 6 months after operation, the hip joint function score and quality-of-life score were significantly improved in both groups in comparison with those before operation (P<0.05). Both FNS and traditional cannulated screw internal fixations can effectively ameliorate the hip joint function, promote fracture healing and improve the quality of life of patients with femoral neck fracture. Compared with cannulated screw internal fixation, however, FNS internal fixation can alleviate operative trauma, postoperative pain sensation and inflammatory response and reduce intraoperative fluoroscopy frequency and postoperative complications, thereby enabling earlier discharge.
