Relationship between the AB0 Blood System and Proximal Femoral Fracture Patterns in the Turkish Population

AB0 blood groups have shown to be associated with increased risk of several orthopedic disorders such as Achilles tendon rupture and hip osteoarthritis. The objective of this study was to investigate relationships between the AB0 blood system and hip fracture patterns, duration of hospitalization, and amount of blood transfusion.

Data of 308 patients treated due to hip fractures in our hospital between 2017 and 2019 were evaluated. Epicrisis reports and X-rays of the patients included in this study were retrospectively screened, and hip fractures were classified as intracapsular and extracapsular fractures. Patients were divided into A, B, 0, and AB groups according to blood groups.

The mean age of the patients was 75.54 ± 13.5 years. Of all patients, 103 had an intracapsular fracture and 205 had an extracapsular fracture. No statistically significant correlation was found between blood groups and fracture patterns. No statistically significant difference was found between the amounts of transfusion according to the blood groups, and no significant difference between the durations of hospitalizations according to the blood groups.

In our study population, we could not find a significant relationship between the AB0 blood system and fracture patterns. We think that these potential relationships could be explained with further comprehensive studies with larger populations.
