1 A spiral fracture happens when the break spirals around the bone, which can happen if the bone is twisted. 2  A compression fracture happens when vertebrae in the spinal column are pushed together in an accident or because of osteoporosis.
Mechanism of injury. 1  A Swedish study in 2006 found most are caused by a simple fall. 2  May be linked to non-accidental injury in children aged <3 years. 3  Usually direct trauma or torsion injury to an upper limb. Occasionally, a fall on to an outstretched abducted arm. Blunt injury/bending forces usually cause transverse fractures. Torsional force tends to result in spiral fracture. Age group affected. The Swedish study found that most fractures occurred in elderly patients. Presentation
