. A practical treatise on fractures and dislocations. e after a week or two that it does not properly support the fragments, and should then be renewed.

If union is delayed beyond that time it is well to let the patientbear part of his weight upon the foot in walking, angular displacementthereby being prevented by a strong plaster encasement. Instead of a Volkmann splint during the first week side splints ofwood or wire or a posterior plaster moulded splint (Fig. 233) or pos-terior and lateral splints (Figs. 245 and 246) may be used, and theymay also, especially the moulded ones, be serviceable during the laterstages if wounds of the anterior soft parts require dressing. A number of devices for maintaining continuous traction have beensuggested, but their inherent defects are such that they have never comeinto general use. Figs. 234 and 235 show two such. Fig. Dr. Neills dressing for continuous traction. Direct pressure by a metal pin or a pad controlled by a screw wasoccasionally used when the projecting end of the upper fragment couldnot otherwise be controlled and especially if it threatened to perforatethe skin. It is now generally deemed better to expose the fracture byincision and remove the cause. In compound fractures the bivalve or fenestrated or interrupted splintmay be used, or anterior and posterior moulded splints one of whichholds the fragments in place while the other is removed that the dress- Fig. 235.
