It is also the last ossification center to fuse, around 22-25 years of age. of the clavicle, along its superior border. is clinically important as the structures are routinely dealt in surgical practice. Cats have free-floating clavicle bones. The knowledge of the neurovascular foramina of the clavicle is clinically important as the structures are routinely dealt in surgical practice. Nutrient foramen (NF) It is a foramen present at the lateral end of the sub-clavian groove and is, generally, found located near the central half of the length of the bone. Knowledge of the localization of nutrient foramina can be useful in certain surgical procedures to preserve the . nutrient foramen is an opening into the bone shaft for passage of blood vessels into the bone for its nourishment and growth, which is very vital for its development in the embryonic and fetal life. The knowledge of the neurovascular foramina of the clavicle. The aim of this review was to determine the prevalence, number, location, and direction of the nutrient foramen. . Coned-down frontal radiograph of the shoulder demonstrates a nutrient foramen of the scapula . Almost all previous studies on clavicle yielded same results. The clavicle's nutrient foramen is a surrogate marker for its nutrient artery. Blood vessels passes through this foramen and enter the medullary cavity of a bone for its nourishment and growth. The foramina are known to mimic oblique fractures on plain radiographs 1. Clavicle Nutrient foreman Long bone A B S T R A C T Introduction: The collar bone is an atypical long bone having a nutrient foramen in the middle one third of the clavicle, along its superior border. DOI: 10.18535/JMSCR/V6I1.07 Corpus ID: 90300629; Morphometric Study of Number, Position and Direction of Nutrient Foramen of Clavicle in Population of Bihar @article{Ratnesh2018MorphometricSO, title={Morphometric Study of Number, Position and Direction of Nutrient Foramen of Clavicle in Population of Bihar}, author={R. K. Ratnesh}, journal={journal of medical science and clinical research . It was. The shaft of the clavicle usually presents one nutrient foramen for the passage of main nutrient artery. A nutrient foramen (plural: nutrient foramina) or vascular channel is a small tunnel through the cortex of a long bone containing a nutrient artery which supplies the bone. nutrient branch from the suprascapular artery clavicular branch of the thoracoacromial artery from the second part of the axillary artery Development Ossification It is the first bone to start ossification at around 5th-6th weeks of gestation. 2 it is the only long bone Some authors suggested that the foramen serves as an entry point for an essential nutrient arterymainly a branch of the suprascapular arterywhich supplies the middle third region of the clavicle, while other studies described that the dominant foramen carries the medial fascicle of the supraclavicular nerve [ 1, 5, 7 ]. The largest nutrient foramen in 19(42.2%) bones was located at the level of proximal one-third of linea aspera; in 17 (37.8%) bones at the level of middle one-third; and in 9 (20%) bones at the level of lower one-third of linea aspera (Figure). Nutrient foramen is the opening present in the shaft of long bone. Methods: 317 macerated human clavicles (167 right and 150 left) were available for the study. The presence, number and size of these foramina and their size were noted. 1 the clavicle it develops intramembranous and is the last bone to complete ossification and first to begin the process. . The shaft. Background: The aim of the present study was to describe the prevalence and topography of the dominant nutrient foramen at the clavicle. The clavicle is an S-shaped bone that is more tubular medially, gradually becoming flatter at its lateral extent. Purpose Fractures of the clavicle, which has an important location and function in the upper extremity and shoulder joint, compose 10% of all fracture cases. The knowledge of nutrient foramen is important in surgical procedures like bone grafting and more recently in microsurgical vascularized bone transplantation. Methods Nutrient foramen is the opening present in the shaft of long bone. Cats have free . Blood vessels passes through this foramen and enter the medullary cavity of a bone for its nourishment and growth. The aim of the present. After detecting the dominant nutrient foramen, the total distance from the sternal surface to the examined nutrient foramen was measured. KEY WORDS: Foramen index, clavicle, nutrient foramen Anatomical variation in position, direction, and number of nutrient foramina in clavicles Although, the presence of double and six nutrient foramina were identified, a single nutrient foramen appeared to be most prevalent in the present study (Table I). It connects the manubrium to the scapula, forming a diarthrodial joint proximally (sternoclavicular) and distally (acromioclavicular). During the osteosynthesis of clavicle fractures and in the post-operative period of patients, considering the detailed morphometric and topographic properties of the nutrient foramen of clavicle is important to avoid the disruption of . Introduction: The collar bone is an atypical long bone having a nutrient foramen in the middle one third. The collar bone is an atypical long bone having a nutrient foramen in the middle one third of the clavicle, along its superior border, and the foramen was observed on the posterior surface contrary to mentioned in literature. Background Nutrient foramen is an opening into shaft of humerus which gives passage to the blood vessels of medullary cavity. Knowing its location may be useful for interpreting fractures and to avoid iatrogenic lesions. [7, 8] Direction of nutrient foramina, as was seen by colored pins, was laterally towards acromial end in 95.95% of bones. .
