RESUMEN
PURPOSE: The purpose of this study is to provide reference data regarding the morphology of vascular foramina (VF) of calcaneus among the Turkish population. METHODS: This study was performed using 49 dry calcanei (26 right, 23 left). The number as well as the location of VF in relation of each surface of calcaneus were evaluated. The total length (TL), the distance between the most posterior point of calcaneus and the largest foramina on the medial (LMS), lateral (LLS), superior (LSS) and inferior (LIS) surfaces were measured and foraminal indexes of the largest foramina on the medial (FI1), lateral (FI2), superior (FI3) and inferior (FI4) surfaces were calculated. RESULTS: The mean values of the TL, LMS, LLS, LSS, LIS were measured to be 74.83 ± 6.00 mm, 41.34 ± 4.78 mm, 31.18 ± 7.63 mm, 49.61 ± 13.40 mm, 39.25 ± 13.56 mm, respectively. The mean values of the FI1, FI2, FI3 and FI4 were calculated to be 55.40 ± 6.21%, 41.73 ± 10.06%, 66.01 ± 16.82%, 52.16 ± 16.80%, respectively. The maximum numbers of VF were detected most commonly on the lateral (28.29%) and medial (26.45%) surfaces, and least commonly on the anterior (0.98%) and posterior (8.29%) surfaces. CONCLUSIONS: VF were observed to be most commonly located on the lateral and medial surfaces, and least commonly on the anterior and posterior surfaces. Having adequate knowledge of the morphologic and morphometric properties of the VF is important in regarding the surgical approaches to the calcaneus towards the aim of reducing the vascular damage, especially in lateral approaches for orthopedists and of using differential sign from cystic lesions for radiologists.
RESUMEN
BACKGROUND: Nutrient arteries pass through the nutrient foramina and reach the spongious part or medullary cavity of the bones. The arterial blood supply and nutrient foramina of the ilium have not been well described in the literature. The aim of this study is to define the numbers and localizations of nutrient foramina of the ilium on the internal surface in accordance with the pelvic brim, as well as the external surface, and furthermore the distances between these foramina with certain anatomical landmarks. METHODS: This study was performed on 57 dry hip bones. The foramina on the external and internal surfaces of the ilium were evaluated separately. The external surface of the ilium was divided into 4 regions in accordance with the gluteal lines to determine the localizations of the nutrient foramina. The foramina on the internal surface were evaluated according to whether they were above or below the pelvic brim. The diameters of the foramina and their nearest distances to certain anatomical landmarks were measured. Furthermore, the risk area of the region above the pelvic brim was determined. RESULTS: : The foramina that were found on the external surface of the ilium were distributed mainly between anterior and inferior gluteal lines (42 foramina-37.17%) and below the inferior gluteal line (57 foramina-50.44%). On the internal surface, 54 nutrient foramina were found above the pelvic brim and 81 were found below. DISCUSSION: The localizations and configurations of all nutrient foramina on the ilium were evaluated morphometrically for the first time.
