As the strain upon the part is increased, one watches carefullyfor the return of muscular spasm or for restriction of the rangeof motion. If the range of motion does not diminish, and if thedeformity that may be present does not increase or does not TUBEBCULOUS DISEASE OF THE HIP-JOINT. 383 appear if it were absent, the brace may be removed at intervalsand finally discarded. As has been stated, the short spica after the Lorenz model isan admirable support during the period of recovery. It checksmotion at the joint, yet it permits the function of support, andthus a gradual rebuilding of the bony structure which has be-come atrophied during the course of the disease. By means ofthis appliance the limb may be held in the desired position ofslight abduction, and it is particularly effective when the limb,because of destructive changes in the joint, is inclined toward Fig. Double hip disease, terminating in bony anchylosis. adduction. It should be stated that the long-continued fixationof the limb, especially if combined with traction, may inducelaxity of the ligaments and hyperextension at the knee, unless itis properly supported by the posterior thigh band. In the casesin which the atrophy is extreme and in which this laxity ispresent the splint may be discarded in favor of the plastersupport with advantage (Fig. 278). This period of supervision even in favorable cases should beprotracted, for no patient can be considered free from the danger 384 OBTROPEDIC SUBGEBY. of relapse for a long time after apparent cure. If there is firmbony union, as in exceptional cases, cure is assured; but if thereis simple fibrous anchylosis, and particularly if there is upward Fig. 278.
