    line is parallel to the long axis. If there is axial dis- placement the so-called riding of the fragments takes place. It is often observed in fractures at the upper third of the femur. (Figs. 112, 114.) 4. Peripheral displacement, in which the fragment is titrned around the long axis of the bo7ie (torsion). (This variety may occur when the body is turned while the extremity is fixed.) If in a complete fracture small bone-fragments are either partly or totally severed from the bone, it is C2i\\&d 3. commi7mtedfracture. (Fig. 136.) If the bone is broken at several points, it becomes a multiple fracture. (Fig. 40.) If a fragment consisting of compact bone is forced into the substance of a cancellated one, an iinpacted fracture is produced. (Fig. 107.) If the fracture is caused by a bullet, it is called a gunshot fracture. The bullet of the army weapon known as the Krag-Jorgensen rifle produces extensive splintering of the diaphysis of the long bones up to a distance of 800 yards. (Fig. 136.) This type of fracture may also be incomplete. In incomplete fractures, which are mostly observed in very flexible bones, the convex corticalis yields and tears, while the concave stratum is only bent. This injury is called infractioit (Figs. 92, 137); it maybe compared to the bending and partial splintering of a green stick, and is mainly observed in childhood. Its predilection is for the deformed legs of rachitic chil- dren, but it may occur in old individuals, where senile atrophy has caused a diminution of the organic sub- stance of the bones. It is also found, as a result of abnormal uterine contractions, as an intrauterine frac-
