What is the medullary canal?
What is the medullary canal?
Medical Definition of medullary canal : the marrow cavity of a bone.
What is medullary cavity in bone?
The medullary cavity is the hollow part of bone that contains bone marrow. The bone marrow makes blood cells and stores fat.
What fills the medullary cavity of the tibia?
Inside the diaphysis is the medullary cavity, which is filled with yellow bone marrow in an adult.
What fills the medullary canal?
The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow. The walls of the diaphysis are composed of dense and hard compact bone.
What is medullary cavity and its function?
The medullary cavity is the space within the long bones of the body below the layer of compact bone tissue. The compact bone tissue is what gives the long bone its strength when providing support to the bone and withstanding the force of muscle attachment during the flexing of muscles.
Does the tibia have a medullary cavity?
There is increased osteoblastic and fibroblastic activity primarily in the endosteum and medullary cavity of the diaphyses of the humerus, radius, ulna, femur, and tibia.
How is the medullary cavity formed?
Blood vessels invade the cavities, and osteoblasts and osteoclasts modify the calcified cartilage matrix into spongy bone. Osteoclasts then break down some of the spongy bone to create a marrow, or medullary, cavity in the center of the diaphysis.
What is the function of the marrow cavity?
Bone marrow is the soft, spongy tissue that is located in the medullary cavities (centers) of certain large bones. Healthy bone marrow is an essential part of the body, as it contains stem cells that produce blood cells and the cells that make up the immune system.
How is medullary cavity formed?
Where does the medullary canal exit the tibia?
The medullary canal of the tibia exits at the margin of the lateral articular facet. As a result of this complex proximal anatomy, there is less sagittal plane space for an intramedullary nail within the tibia metaphysis with a medial or central insertion path.

What is the size of intramedullary nail in the tibia?
Complete orthogonal radiographs of the entire tibia and fibula are important to determine whether the patient’s intramedullary canal is large enough to accommodate an intramedullary nail (approximately 8 mm) and identify any preexisting deformity that may preclude nail placement. Most modern cannulated nail designs start near 8 mm in diameter.
What is the proximal cortex of the tibia?
The triangular-shaped proximal tibia is narrowest medially, and the proximal medial cortex tibia is obliquely oriented to the frontal plane. The medullary canal of the tibia exits at the margin of the lateral articular facet.
