This would be a hairline fracture or stress fracture. These only occur in weight bearing bones.
Closed spiral fracture
This type of line usually indicates a spiral fracture, brought about by an excessive amount of torque applied along the axis of the bone.
Greenstick Fracture
cancellous bone
== ==
The shaft of a long bone is the center area, as in the middle of the bone, not at one of the ends. Take a tree as an example - the roots would be one end, the leaves the other end and the shaft would be the trunk.
An undisclosed fracture is a broken bone that is not apparent on examination. Often these kind of fractures are only discovered after they are healed.
A brake in a bone is called a fracture. It occurs when the bone is broken due to trauma or stress. Fractures can range from minor cracks to complete breaks that may require medical intervention to heal properly.
The outside layer of compact bone tissue, also known as the periosteum, surrounds the bone shaft, providing protection and support. It contains blood vessels, nerves, and stem cells that play a role in bone growth and repair.
depending what kind of fracture and severity it can take 5-10 weeks
Greenstick fracture
Any kind of fracture that is possible to be imagined, from a greenstick incomplete nondislocated fracture to a comminuted open severely displaced fracture. The more common fractures are mid-diaphyseal (mid-shaft) fracture of the femur and the tibia, both open and closed, often displaced due to muscular contraction in reponse to trauma.
