. A practical treatise on fractures and dislocations. ases as that represented in Fig. 93 cannotbe entirely foreign to the direction and degree of the the fracture is transverse the lateral displacement may be slightor entirely absent and the periosteum may remain untorn. Longitu-dinal fracture with comminution was seen in one case, and Hamiltonreports another in which the line ran from the articulation upward andoutward for one and a half inches. The fragments overlapped three-fourths of an inch and were firmly united. In two cases the end ofthe outer fragment lay underneath the inner one and both were directedupward and backward. The outer end of the inner fragment is actedupon more strongly by the sterno-cleido-mastoid muscle than by anyother, the effect of which is to draw it upward, and this effect isincreased by the pressure of the outer fragment when that is forced infront of and below the other, so that whenever the two fractured sur-faces leave each other the inner fragment is likely to incline upward. Fig. Fracture of the clavicle, inner third. (Guklt.) Multiple Fractures. But few cases are recorded in which the bonehas been broken in two or more places ; in some the fracture was bydirect, in others by indirect, violence. Both fractures have been foundin the middle third, but more commonly they occupy different one fracture has been in the acromial, and the other in the inneror middle third, the intermediate piece has not shown much displace-ment, and each fracture has followed the usual course of a single one;but when the fractures have been within or close to the limits of themiddle third, the displacement has been very notable. Complications. Complications of fracture of the clavicle consist ininjuries to the vessels, nerves, and lungs, and are exceedingly rare,excluding gunshot wounds in which the complications are produced bythe ball and not by the fractured bone.
