(B) Dislocations of the Clavicle (a) Sternal dislocation of the clavicle—i. e., dislo-cation of the sternal end of the clavicle—presents variousforms : Anterior dislocation (luxatio prcestenialis). Upward disloca-tion (luxatio siqwa- \\ nsternalis). Both these vari-eties are producedindirectly by lever-age, the first ribacting as a ful-crum; or they maybe produced by aforce acting fromwithout, dependingon the position ofthe clavicle,whether it is di-rected backwardor downward. Inanterior disloca-tion secondary dis-placement niaytake place. Posterior dislo-cation (luxatio retrosternalis).duced by direct Fig. 45.—Eecent fracture in the acromialthird of the clavicle. The normal clavicleon the sound side measures 18 cm. in inner fragment measures 16 cm., leaving2 cm. for the acromial fragment. The medianextremity of the latter is distinctly raised andpartially connected with the inner fragment,which is also displaced upward and can bedistinctly felt under the skin. The patientsname was Warnke, sixty-eight years of age.(Authors observation in the surgical clinicat Greifswald, 1896.) This is very rare ; it is pro- 136 FRACTURES AND DISLOCATIONS. PLATE Dislocation of the Acromial End of the Clavicle.— Fig. 1.—The abnormal prominence of the clavicle is very the outer side and below we see the normal rotundity of the shoulderAvith the acromion. The dislocation is seen even more plainly in theposterior view shown in figure 1 b. The line of the spine of the scapulais directed toward the acromi
