Case: Three male patients, 8-, 13-, and 18-year-old, all developed posttraumatic cubitus varus elbow deformity after distal humerus supracondylar fractures. Each underwent a distal humerus osteotomy with application of a hexapod external fixator to gradually correct the deformity.
Conclusion:In patients with cubitus varus malunion, the stability of the hexapod external fixation, percutaneous nature of the osteotomy, and availability of running a residual computer-assisted program provides a consistent technique for deformity correction. E lbow fractures are common in pediatric patients and can present in a wide spectrum of severity [1][2][3][4] . Cubitus varus deformity is the most common late complication resulting from supracondylar fractures with an incidence of 3% to 57% [5][6][7][8] . The etiology of the deformity is primarily malunion of the distal humerus, in addition to physeal growth disturbances and osteonecrosis 9 . The deformity predisposes to posterolateral rotary instability, ulnar neuropathy, snapping triceps, loss of elbow range of motion, and elbow pain; hence, some authors advocate for intervention to correct this deformity 9-12 .
