Abstract
Purpose: Vascularization of bones is crucial for bone growth and repair. The nutrient artery, passing through the nutrient foramen, is key to bone blood supply, but its impact on fracture healing and complications is not fully understood. The study aims to investigate the morphology and location of the nutrient foramen in the femoral diaphysis and to understand its clinical implications for fractures.
Methods: In this study, 88 adult dry femurs of unknown age and sex were examined. The characteristics of the nutrient foramina, including number, size, direction, and localization were evaluated. The foraminal index [(distance from foramen to proximal end of femur/total length of femur) × 100], was employed to categorize the regions [Region-I, 0-33.33; Region-II, 33.34-66.66; Region-III 66.67-100].
Results: The majority of the femurs had one or two foramina (92.94%). Of the total number of nutrient foramina, 121 (97.58%) were directed towards the proximal end, while three (2.42%) were horizontal. The majority of foramina were detected in sizes 18G (34.67%) and 20G (27.42%). All nutrient foramina were found on the posterior surface of the femur and adjacent to linea aspera. Sixteen nutrient foramina were located (12.90%) in Region-I, 104 (83.87%) in Region-II, and 4 (3.23%) in Region-III.
Conclusions: The nutrient foramina were typically located in the middle third of femur, adjacent to linea aspera on the posterior surface of femur. This observation indicates that the anterior surface is safer for surgery, while caution is needed near the linea aspera on the posterior surface.
期刊介绍:
Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit.
Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest.
Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems.
Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
