The reduction of old dislocations may usuallybe accomplished by the manipulations appropriate for re-cent dislocations of the same variety ; but occasionally the 448 DISLOCATIONS. use of more forcible extension is required, which is madeby bands and pulleys or by vertical extension (Fig. 339).The first step in the reduction of old dislocations consistsin thoroughly breaking up the adhesions which havebeen formed between the displaced bone and the surround-ing tissues; this has, in some cases, resulted in the lacera-tion of muscles, nerves, and bloodvessels, and in fractureof the displaced bones or neighboring bones, so thatthe manipulations should be made with the least forcethat will accomplish the object desired.
