Growth of Cartilage and Bone Tissue01:27

Growth of Cartilage and Bone Tissue

3.9K
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

6.7K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Gross Anatomy of Bone01:17

Gross Anatomy of Bone

8.6K
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...

Bone Markings01:26

Bone Markings

7.7K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

4.3K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

9.8K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

Area of Science:

  • Orthopedic Surgery
  • Anatomy
  • Radiology

Background:

  • Clavicle fractures account for 10% of all fractures.
  • Understanding nutrient foramen anatomy is crucial for surgical success and preventing complications.
  • The nutrient foramen supplies arterial blood to the clavicle.

Purpose of the Study:

  • To detail the morphometric and topographic properties of the clavicle's nutrient foramen.
  • To provide anatomical data for optimizing clavicle fracture osteosynthesis.
  • To enhance patient outcomes by preventing iatrogenic injury to the nutrient artery.

Main Methods:

  • Computed tomography (CT) scans of 116 healthy individuals were analyzed.
  • Three-dimensional reconstructions were performed using Horos v3.3.3 software.
  • Distances from the nutrient foramen to the sternal end and edges of the clavicle were measured and statistically analyzed using SPSS v21.

Main Results:

  • The nutrient foramen of the clavicle is predominantly located closer to the sternal end.
  • The minimum distance from the nutrient foramen to the sternal edge was 3.3 cm.
  • Significant gender differences in foramen location were observed (favoring males), but age had no impact.

Conclusions:

  • The nutrient foramen's proximity to the sternal end is a key anatomical finding.
  • Maintaining arterial supply during sternal-end clavicle fracture surgery is vital.
  • This anatomical knowledge can improve surgical techniques and patient recovery.
