FNS is efficacious for the treatment of femoral neck fractur
This study aimed to compare the clinical efficacy and complications of FNS with those of inverted cannulated cancellous screws (ICCS) for the treatment of femoral neck fractures in adults. The femoral neck system FNS may be a valid alternative for treating femoral neck fractures, but few studies have compared the outcomes between FNS and cannulated cancellous screws.

This retrospective study evaluated patients with femoral neck fractures who underwent FNS or ICCS internal fixation. The operative time, intraoperative blood loss, number of fluoroscopies, length of surgical incision, length of hospital stay, time to fracture healing, and other indicators were compared between the two groups. The incidence of complications such as nonunion, avascular necrosis of the femoral head, loosening of the internal fixation, and shortening of the femoral neck during follow-up was also assessed in both groups.

Results:
--Among the 92 patients included, 47 and 45 patients were categorized into the FNS and ICCS groups, respectively.

--There were no significant between-group differences in sex, age, side of the injured limb, and type of fracture and in operative time, intraoperative blood loss, incision length, and length of hospital stay.

--The incidence of complications such as fracture nonunion, avascular necrosis of the femoral head, and screw loosening was also comparable between the two groups.

--However, the number of fluoroscopies was significantly lower in the FNS group than in the ICCS group.

--The fracture healing time was also significantly lower in the FNS group than in the ICCS group.

--The femoral neck shortening and Harris hip score at the last follow-up were significantly better in the FNS group than in the ICCS group.

Conclusively, FNS enhances hip functional recovery and lowers femoral neck shortening rate and fluoroscopy exposure after femoral neck fractures. As a result, FNS could be used instead of ICCS to treat femoral neck fractures.
