Arthrodesis, in cases of patients with unilateral, irreducible corugenital dislocation, assures the best results as far as pain and fatigue are concerned. The operation should be limited to patients of the lower economic level. Sociologists estimate that a child has one chance in twelve of rising from a low social-economic level to the so-called middleclass level. If such a child must expect to earn his or her living through manuual labor, a painless hip is almost a necessity.
In the small series of cases presented, uniformly good results were obtained by arthrodesis. Other clinics have also reported similar results in their small series of cases.
