The differential diagnosis of right elbow injury included fractures of the supracondylar area, medial condyle or lateral condyle of humerus
, elbow dislocation, Monteggia or Monteggia variant fracture dislocation.
The initial X-ray studies of the elbow showed a fracture of the medial condyle of humerus
. The bone fragment was displaced laterally by the traction of the flexor muscles; however, dislocation of the humeroulnar joint was not observed (Figure 1).
Fractures of the medial condyle of humerus behave as the mirror image of lateral condyle fractures.
Clinicoradiologically, it was a case of left-sided cubitus varus deformity with internal rotation of left forearm with posteromedial subluxation and restricted movement of left elbow in a 9-year-old boy due to united ill-developed medial condyle of humerus following its treatment by closed reduction and percutaneous k-wire fixation more than 3 years ago.
Fracture of Medial Condyle of Humerus in Preoperative X-ray
The distance between the medial and lateral condyle of humerus
on the left side was 56.11, [+ or -] 5.41 mm and 57.64, [+ or -] 5.33 mm on the right side.
Shimada et al  had successfully treated the nonunion lateral condyle of humerus presenting at an average period of five years after the injury, average age of the patients in his study was nine years.
CONCLUSION: The authors conclude that nonunion fracture lateral condyle of humerus in children can be successfully treated even if neglected for a period up to eight weeks after the initial injury.
