It most likely comes from a forseful twist of the arm!!
To add to that: it's caused by an extreme muscle contraction, in other words it's actually your arm muscles that break you upper arm bone! the break curves around the bone, hence the name. also known as "ball thrower's fracture". it's a relatively rare type of injury, which i unfortunately have at the moment. i tripped over a brick walkway and landed on my shoulder on the grass. my muscles tensed up to protect me but ironically did so so severely that my arm broke! from personal experience i can add that it's extremely painful and uncomfortable, esp because it's my right arm and i am a jeweler.
The medical term for a fracture in the middle third of the humerus is a "midshaft humeral fracture." This type of fracture can occur due to trauma or injury and may require immobilization or surgical intervention for proper healing. Complications such as nerve or blood vessel damage can also occur with this type of fracture.
Spiral bone fractures, or any fracures for that matter, could be caused by malnourishment of the bones. Weak bones=more breaks and fractures. Bone injury is almost always a result of trauma, however.
A comminuted fracture of the surgical neck of the right humerus is a fracture where the bone is broken into multiple pieces near the top of the arm bone. Surgery may be needed to realign the bone fragments and stabilize the fracture with plates, screws, or pins to promote proper healing and restore function. Physical therapy is often recommended post-surgery to regain strength and mobility in the arm.
A spiral fracture is a type of fracture where the bone has been twisted apart. This type of fracture is often the result of a rotational force applied to the bone. Treatment may involve realignment and stabilization to promote proper healing.
The Humerus.

it depends on the fracture if surgery is required and the recovery period
A Stress fracture
Spiral Fracture
A spiral fracture.
The humerus.
Spiral
This is called an open fracture of the humerus.
it will die
6-8 weeks
In English, this is a spiral fracture.
In a femur it would be something like a hard landing on your foot causing pressure and thereby creating a spiral as it cracked in an upward motion. In an arm is similar. It takes a lot of force to cause a spiral fracture.
