An x-ray image of a spiral fracture to the left humerus of a 27-year-old male. The injury was sustained during a fall.

A spiral fracture (a.k.a. torsion fracture) is a bone fracture occurring when torque is applied along the axis of a bone.^[1] While torsional forces are being applied along the parallel axis of a bone, planes perpendicular to this axis are not affected. Tension is exerted upon one part of the bone, while compressive forces are exerted upon the other. When these forces have exceeded the limit tolerable by the bone, fracture occurs.^[1]

Notable persons with spiral fractures[edit]

Chad Billingsley, American baseball pitcher, slipped on ice and suffered a spiral fracture of the fibula.^[2]
Ryan Bradley, American figure skater, suffered a spiral fracture in the humerus of his arm while playing dodge ball.^[3]
Michael Russell, American tennis player, while serving suffered a spiral fracture of the humerus bone.^[4]
Jeremy Ten, Canadian figure skater, sustained a spiral fracture of the fibula.^[5]

BACKGROUND: Humeral fracture following subpectoral biceps tenodesis has been previously reported; however, there are no published biomechanical studies reporting the resulting torsional strength of the humerus. Our purpose was to determine if there is an increased risk of humerus fracture after subp
