A shaft in a circular hole has 2 degrees of freedom: rotation around its own axis and translation along the axis of the hole.
Spiral ramp.
A fidget spinner consists of two circular objects (spinner arms) and a central shaft. The spinner arms spin around the central shaft when flicked, providing a satisfying sensory experience for users.
A screw is an inclined plane wrapped around a cylinder or shaft. It allows for the movement of materials along its length through rotational force.
The weight of an STX AL6000 lacrosse shaft is typically around 5.6 ounces.
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.
This would be a hairline fracture or stress fracture. These only occur in weight bearing bones.
greenstick fracture
Closed fracture of shaft of clavicle
A "boxers" fracture generally refers to a fracture of the metacarpal bones-more commonly the fith metacarpal anywhere between mid shaft and the distal(knuckle) end of the the bone.

Fractures are termed complete if the break is completely through the bone and described as incomplete or "greenstick" if the fracture occurs partly across a bone shaft
The straight part in the middle, away from both ends of the bone
CPT Code 24505 : Closed treatment of humeral shaft fracture; with manipulation, with or without skeletal traction
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.
The periosteum is the membrane around the shaft of a long bone.
