Cubitus Varus Deformity Posttraumatic: A Case Report and Review of the Literature

Abstract

Abstract The cubitus varus, frequently caused by a vicious callus, is the most common complication of the children’s supracondylar fractures, resulting from inadequate reduction or secondary displacement. We relate one case to analyze this complication. Our patient benefited from a step-cut osteotomy; the discussion was around different techniques of osteotomy to restore physiological valgus, including lateral closing-wedge, dome, three-dimensional, and step-cut osteotomies. The cubitus varus can be operated when the esthetic problem exceeds 15°, it associates a displacement in the three planes, whereas a correction in a single coronal plane can be accepted, the hyperextension must be treated for children over 10 years old. Humeral osteotomy is used to correct this deformity and to avoid later complications, such as ulnar nerve palsy, posterolateral rotatory instability, and secondary distal humeral fracture. The prevention and knowledge of the criteria for reduction supracondylar fractures should reduce the incidence of cubitus varus.
