Comparative results of the femoral neck system versus the dynamic hip screw for stable femoral neck fractures in older adults in Korea: a retrospective cohort study: Byung-Chan Choi, Byung-Woo Min, Kyung-Jae Lee, Jun-Sik Hong; J Musculoskelet Trauma 2025;38(4):203-211.

Abstract PDF: Background
This study aimed to compare the clinical and radiological outcomes of the femoral neck system (FNS) and the dynamic hip screw (DHS) for the internal fixation of stable femoral neck fractures in older adults.
Methods
This retrospective cohort study included 48 matched older adult patients based on sex, age, BMI, and osteoporosis status, who had undergone internal fixation with either FNS or DHS for stable femoral neck fractures between January 2010 and December 2022. To minimize selection bias, a 1:1 case-control matching was performed based on sex, age, body mass index (BMI), and the presence of osteoporosis. A total of 48 patients (24 in each group) were included. We compared perioperative data (operation time, hemoglobin change, transfusion rate), functional outcomes using the Koval score, and radiological outcomes, including union rate, femoral neck shortening, and complication rates.
Results
The mean operation time was significantly shorter in the FNS group than in the DHS group (60.9 minutes vs. 70.8 minutes; P=0.007). There were no statistically significant differences between the two groups in the union rate (87.5% in FNS vs. 95.8% in DHS), femoral neck shortening, final Koval score distribution, or overall complication rates (12.5% in both groups).
Conclusions
For treating stable femoral neck fractures in older adults, the FNS demonstrated comparable clinical and radiological outcomes to the DHS, with the distinct advantage of a shorter operation time. While these findings suggest that the FNS is a promising and safe alternative that may reduce the surgical burden, definitive conclusions are precluded by the small sample size, warranting further research to corroborate these results. Level of evidence: IV.

Clinical Outcomes and Radiologic Characteristics of Insufficiency Femoral Neck Fracture in Elderly Patients: Hee-Uk Ye, Kyung-Jae Lee, Byung-Woo Min, Kyung-Hwan Lim, Beom-Soo Kim, Young-Hoon Kim; J Korean Fract Soc 2021;34(1):1-7. Published online January 31, 2021; DOI: https://doi.org/10.12671/jkfs.2021.34.1.1

Abstract PDF: Purpose
In elderly patients, femoral neck insufficiency fractures that occur without a history of trauma are difficult to diagnose and treat, so it is emphasized that early suspicion of fractures and additional diagnostic tests are conducted. Materials and Methods: Between December 2010 to December 2019, 12 femoral neck insufficiency fractures (group 1) were evaluated by comparing them with 50 traumatic femoral neck fractures of a similar age. Along with demographic data, neck cortical thickness, shaft cortical thickness, head diameter, neck width, trochanter width, shaft width, neck-shaft angle, hip axis length, femoral neck index on the simple radiographic image were compared. Results: Seven of the 12 cases were non-displaced fractures, and it took an average of 19.2 days to diagnose the fracture after the symptoms occurred. The height was smaller than the control group at 149.1 cm in group 1 and 157.2 cm in group 2 (p<0.001). The cortical thickness of the medial femoral neck showed significant differences between the two groups: 3.16 mm in group 1 and 4.11 mm in group 2 (p=0.004). There was no statistical difference in the other measurements. Conclusion: Femoral neck insufficiency fracture often has a delayed diagnosis because of the characteristics of the fracture. The cortical thickness of the medial femoral neck in simple radiographic images can help suspect femoral insufficiency fractures in elderly patients when considered with detailed medical history taking and a physical examination.
