Cubitus yarns deformity is the result of disturbed carrying angle of the elbow after maturated supracondylar fracture of the humerus in children the normal carrying angle can be restored bysupracondylar osteotomy. the most difficulty is in maintaining correction after operation. This operation was performed in 28 patients, three methods of holding position were used. in seven patients (25%) external plaster of paris alone, in five patients (18%) Kirshner wires were used and in 16 patients (57%) we used the technique described by French (1959) and modified by Bellmore (1984). The Results were assessed after osteotomy according to the method of Fixation. The french's method proved to be 5(0 and satisfiretory.
INTRODUCTION
Cubilus varus (Gun Stock deformity) is the most common long term complication of supracondylar fracture of the humerus in children(lVlitchell and Adams, 1961) although Functional impairment is rare, the deformity is so significant that parents usually request a corrective operation. Several techniques a corrective osteolomies have been described. Sins (1939) described a cuneiform osteotomy,
King and Secor (1951) described .a medially based opening wedge, French (1959) first described a lateral closing wedge osteOtomy held with screws and figure of eight wire and this remains the most popular method of correction. Many authors Clarson and Rosman, (19820 Bellemore et al. (1984). have used a modifications of French's technique.
Oppenbeim et at (1984) reported a significant incidence of residual varus after correction due to post
