RADIUS’UN FORAMEN NUTRİCİUM’U İLE İLGİLİ BİR ARAŞTIRMA

Öz

Amaç: Uzun kemiklerin beslenmesini sağlayan arterler, foramen nutricium (FN) adı verilen açıklıklardan geçer. Radius’taki FN'ler ile ilgili yapılan çalışma sayısı oldukça azdır. Bu nedenle,bu çalışmada FN'lerin radius üzerindeki varlığını, sayısını, yönünü ve anatomik lokalizasyonunu belirlemek amaçlanmıştır. Gereç ve Yöntem: Bu çalışmada toplam 133 adet yetişkine ait kuru radius kemiği incelendi. FN'lerin radius üzerindeki varlığı, sayısı, konumu ve yönü belirlendi. FN’nin radius’un en proksimal noktasına olan en kısa mesafesi (PM), FN’nin bulunduğu seviyedeki transvers çap (TÇ), FN’nin tuberculum dorsale’nin en belirgin noktasına olan mesafesi (TDM) ölçüldü. Ayrıca foraminal indeks (FI) hesaplandı. Bulgular: 130 (%97,7) radius’ta tek FN vardı, 3 (%2,3) radius’ta ise FN yoktu. FN'ler en sık radius’un facies anterior’unda (%80; 104 kemik) ve orta 1/3 (%78,5; 102 kemik) kısmındaydı. Tüm FN'lerin yönü dirseğe doğruydu. PM, TÇ ve TDM sırasıyla ortalama 82,72±11,4 mm, 129,99±15,41 mm ve 14,6±1,97 mm olarak hesaplandı. Ortalama FI 35,6±4,64 olarak kaydedildi. Sonuç: Bu çalışma, nutrient foramenin dorsal tüberküle olan uzaklığı gibi ek bilgiler sağlamaktadır. Çalışma sonuçlarımızın, radius’taki FN ile ilgili uygulamalarda klinisyenlere yardımcı olması beklenmektedir.

AN INVESTIGATION REGARDING NUTRIENT FORAMEN OF THE RADIUS

Öz

Objective: Arteries that provide nutrition to the long bones pass through openings called nutrient foramen (NF). The number of studies on NFs of the radius is quite scarce. Therefore, this study aimed to determine the presence, number, direction, and anatomical localization of NFs of the radius. Material and Method: A total of 133 dry adult human radii were investigated in this study. The presence, number, position, and direction of NFs of the radii were determined. The shortest distance of NF to the most proximal point of the radius (DPE), the transverse diameter of the radius at the level of the NF (TD), and the shortest distance of the NF to the most prominent point of the dorsal tubercle (DDT) were measured. Furthermore, the foraminal index (FI) was calculated. Result: A single NF was found in 130 (97.7%) bones, and 3 (2.3%) radii did not have NF. The NFs were most commonly on the anterior surface (80%, 104 bones) and middle 1/3 (78.5%, 102 bones) part of the bones. All NFs were towards the elbow. The DPE, TD, and DDT were meanly 82.72±11.4 mm, 129.99±15.41 mm, and 14.6±1.97 mm, respectively. The average FI was 35.6±4.64. Conclusion: This paper provides additional information, such as the distance of nutrient foramen to the dorsal tubercle. Our results may help clinicians during applications related to the NF of the radius.
