There is, praetieally sjieakini;, no spontaneous out-growth of knoek-kuee deformity, such as is not infre-quently observed in the ojipositi of bow-leg. Treatment by Braceft.—Vhti most efticieut brace in thetreatment of genu valgum is tliesim|:ile straight steel baror splint extending from the trochanter to the heel of theshoe, witliout joint at the knee. The greater efficacy ofthe rigid bar as compared witli tlie jointed brace is ex-plained l)y tlie fact tliat tlie rectifying force acts con-stantly when tlie joint is fixed, preventing the attitudeof flexion so cliaracteristic of tlie deformity. The simplest and clieapest brace is tliat of Thomas(Fig. 8093), which consists of a light steel bar jirovided?witii a jiad at its upper end for pressure against the tro-.

In the more extreme cases, in which the knees and tliiglisare lialiitually flexed, the addition of a pelvic band at-tached to the uprights by a free joint at the hips, adds tothe comfort and elliciency of the apparatus, as the atti-tude of the fe<tcaii be Iegulated by twisting the uprightsslightly, or the pelvic band may be divided, the twohalves being attached to one antJther by straps and Imckles(Fig. 3098).
