Background: Closed reduction and percutaneous cannulated screw fixation is the preferred surgical method for treating femoral neck fractures in elderly patients under 70 years old. The key to the operation is the precise insertion of the guide pin after the successful reduction. However, there is no universally accepted standard for the localization of the guide pin insertion point. This study introduces our invention of a localization method for guide pin insertion points.
Methods: We used fluoroscopic frequency, operative time, union rates, and complications to retrospectively evaluate the treatment and outcome of femoral neck fractures using our localization method for guide pin insertion points. The study included ten patients treated at Affiliated Hospital of Shandong University of Traditional Chinese Medicine between 2010 and 2014 for femoral neck fracture using our localization method for guide pin insertion points.
Results: Our results showed that the mean number of fluoroscopies was 5 (range, 4-8), and the mean operative time was 32 minutes (range, 25-51 minutes). All 10 patients achieved union at an average of 3.4 months (range, 2.8-6.2 months) without complications after the operation. The average follow-up time was 13.2 months (range, 12.2-16 months). The treatment of femoral neck fracture with our localization method for guide pin insertion points resulted in satisfactory curative efficacy without complications.
Conclusions: Our localization method offers distinct advantages, including the accuracy and simplicity of the operation, a low rate of complications, and adequate biomechanical stability. As such, it provides a feasible method for clinical treatment.
