What is the defining feature of an oblique fracture?

An oblique fracture is characterized by a break that occurs at an angle to the long axis of the bone. This feature distinguishes oblique fractures from other types, such as transverse fractures, where the break follows the straight line of the bone's long axis, or spiral fractures, which involve a twisting force. The angle of the fracture line in oblique fractures results from a force that does not apply directly along the long axis, leading to a unique angular pattern of the break. This distinction is important for correct diagnosis and treatment, as the management may differ based on the fracture's orientation and characteristics.
