Efficacy of Femoral Neck System Fixation vs KHS Femoral Neck Dynamic Compression Locking Plate System in Femoral Neck Fracture.

Background: Femoral neck fracture is acknowledged as one of the common injuries in clinical orthopedics. Our study was aimed at investigating the efficacy of femoral neck fixation vs the KHS dynamic compression locking plate system in the treatment of femoral neck fracture.

Methods: This was a prospective study. A toteal of 90 patients with femoral neck fracture who were admitted to The Third Hospital of Hebei Medical University in Shijiazhuang, China from August 2017 to March 2020 were enrolled in our study. The patients were randomly divided into the control group (45 patients allocated to intervention with the novel femoral neck dynamic compression locking plate system) and the study group (45 patients who underwent femoral neck system fixation). Intraoperative blood loss, surgery duration, fracture healing time and related complications in the 2 groups were monitored and evaluated. The recovery of hip joint function at different times in the 2 groups were closely monitored.

Results: The 2 groups completed the surgery process, and the incision healed. All patients were followed up for 6 to 8 months, with an average follow-up time of 7.01 ± 0.21 months. Surgery duration, length of hospital stay and fracture healing time in the study group were significantly lower than in the control group (P < .05), while no significant difference was found in intraoperative blood loss between the 2 groups (P > .05). At 1 and 3 months after surgery, hip joint function in the study group was significantly higher than in the control group (P < .05), but 6 months after surgery, there was no significant difference between the 2 groups (P > .05). There were no complications in the study group, whereas 1 patient had a complication in the control group. The total incidence of complications in the study group was lower than in the control group, but the difference was not significant (P > .05).

Conclusion: Femoral neck system fixation demonstrated superior efficacy to the KHS femoral neck dynamic compression locking plate system in femoral neck fracture, and is considered as a valid method for wide application.
