What passes through nutrient foramen of clavicle?

What passes through nutrient foramen of clavicle?

Blood vessels
Blood vessels passes through this foramen and enter the medullary cavity of a bone for its nourishment and growth. The shaft of the clavicle usually presents one nutrient foramen for the passage of main nutrient artery.

Where is nutrient foramen in clavicle?

Conclusion: Nutrient foramen is mostly located closer to the sternal end of clavicle. Especially during osteosynthesis of clavicle fractures at the sternal end, maintaining the arterial supply of clavicle is of great importance for increasing the post-operative life quality of patients.

What is the nutrient foramen in bone?

Background Nutrient foramen is an opening into shaft of humerus which gives passage to the blood vessels of medullary cavity. The knowledge of nutrient foramen is important in surgical procedures like bone grafting and more recently in microsurgical vascularized bone transplantation.

What structure passes through the nutrient foramen?

nutrient arteries
The nutrient canal(foramen)is directed away from the growing end of bone. The growing ends of bones in upper limb are upper end of humerus and lower ends of radius and ulna. In lower limb, the lower end of femur and upper end of tibia are the growing ends. The nutrient arteries along with veins pass through this canal.

How is nutrient foramen formed?

The nutrient artery enters a long bone via an obliquely oriented canal, that can appear as a radiolucent line passing through the cortex into the medullary portion of the diaphysis of the bone.

Where does nutrient artery come from?

The nutrient artery enters the marrow cavity of long bones through the nutrient canal and branches to run parallel to the long axis in the central part of the marrow cavity forming the central arteries.

What is the clavicular notch?

Medical Definition of clavicular notch : a notch on each side of the upper part of the manubrium that is the site of articulation with a clavicle.

What is the growing end of clavicle?

At its flattened lateral end (acromial end), it articulates with the acromion, a process of the scapula (shoulder blade), at the acromioclavicular joint. The rounded medial region (sternal region) of the shaft has a long curve laterally and anteriorly along two-thirds of the entire shaft.

What does nutrient foramen allow?

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.

What are nutrient canals?

Nutrient canals are anatomic structures of the alveolar bone through which neurovascular elements transit to supply teeth and supporting structures.

What is the nutrient foramen scapula?

The long bones have one major arterial supply which is the nutrient artery that reaches the bone through the nutrient foramen. The scapula (similar to the clavicle and ilium) is a flat bone which vascularization comes from superficial periosteal arterioles.

Why nutrient foramen is directed away from growing end exception?

The direction of nutrient foramina in human long bones is directed away from the growing end. This is due to one end of long bone is growing faster than the other end [5].

Where is the nutrient artery located?

The peroneal artery gives off a branch, the nutrient artery, which enters the fibula posterior to the interosseous membrane at the nutrient foramen 15 cm below the styloid process in the posterior medial edge of the mid-fibula, two-fifths of the way down.

What is the space between the clavicle called?

The suprasternal notch, also known as the fossa jugularis sternalis, jugular notch, or Plender gap, is a large, visible dip in between the neck in humans, between the clavicles, and above the manubrium of the sternum. Suprasternal notch.

What is the job of the nutrient foramen?

Nutrient foramen is a natural opening into the shaft of a bone, allowing for passage of blood vessels into the medullary cavity.

What is Conoid tubercle?

The conoid tubercle also known as the coracoid tuberosity (not to be confused with the coracoid process of the scapula) is a bony prominence on the inferior surface of the lateral third of the clavicle.

Does the nutrient foramen have blood vessels?

A nutrient foramen is a small, smooth-walled hole for blood vessels found on the external surface of a bone.

What is the length of nutrition Canal?

Considering the length of nutrient artery canal in the medullary cavity (AP radiograph; 23.6 ± 8.8 mm, CTL radiograph; 23.5 ± 6.7 mm), measurements of the distance between the tip of the trochanter and nutrient artery canal clearly showed that the radiolucent lines seen on the AP and CTL radiographs correspond to one …
