Anatomical and clinical importance of proximal femur morphometry: a study on dry bones

Öz

Aim: This study aims to evaluate the clinical relevance of using the obtained data in orthopedic surgery, implant design and biomechanical applications by analyzing the morphometric parameters of the head and neck parts located in the proximal part of human dry femur bones. Method: On 70 adult dry femurs (39 right, 31 left), head of femur diameters, neck of femur diameters and circumferences, fovea for ligament of head of femur dimensions, intertrochanteric length, inclination and Alsberg angles, and total femur lengths were measured. Comparisons between sides and correlation analyses were performed. Results: According to the measurement results, the mean vertical diameter of the femoral head was found to be 45.41±3.65 mm, and the mean vertical diameter of the femoral neck was found to be 32.91±3.47 mm. The mean inclination angle was found to be 127°±6.52, and the total femur length was found to be 425.99±32.23 mm. Many statistically significant positive correlations were found between the parameters. Strong correlations were observed between the head of femur diameters and the neck of femur and femur lengths (p<0.001). Fovea for ligament of head of femur parameters showed weaker relationships with other measurements. Conclusion: Morphometric analysis of the proximal femur provides valuable contributions to clinical applications, especially in terms of patient-specific planning and biomechanical modeling.

Proksimal femur morfometrisinin anatomik ve klinik önemi: kuru kemikler üzerinde bir çalışma

Öz

Amaç: Bu çalışma, insan kuru femur kemiklerinin proksimal bölümünde yer alan baş ve boyun kısımlarına ait morfometrik parametreleri analiz ederek, elde edilen verilerin ortopedik cerrahi, implant tasarımı ve biyomekanik uygulamalarda kullanım potansiyelini değerlendirmeyi amaçlamaktadır. Yöntem: 70 erişkin kuru femur (39 sağ, 31 sol) üzerinde, caput femoris çapları, collum femoris çapları ve çevresi, fovea capitis boyutları, intertrokanterik uzunluk, inklinasyon ve Alsberg açıları ile toplam femur uzunlukları ölçüldü. Taraflar arası karşılaştırmalar ve korelasyon analizleri gerçekleştirildi. Bulgular: Ölçüm sonuçlarına göre, caput femoris’in vertikal çapı ortalama 45.41±3.65 mm, collum femoris’in vertikal çapı ise 32.91±3.47 mm olarak bulunmuştur. İnklinasyon açısı ortalama 127°±6.52 mm, toplam femur uzunluğu ise ortalama 425.99±32.23 mm’dir. Parametreler arasında istatistiksel olarak anlamlı çok sayıda pozitif korelasyon saptanmıştır. Özellikle caput femoris çapları ile collum femoris ve femur uzunluğu arasında güçlü korelasyonlar gözlenmiştir (p<0.001). Fovea capitis parametreleri ise diğer ölçümlerle daha zayıf ilişkiler göstermiştir. Sonuç: Proksimal femurun morfometrik analizi özellikle hasta spesifik planlamalar ve biyomekanik modellemeler açısından klinik uygulamalara değerli katkılar sunmaktadır.
