Abstract
The lateral condylar fractures of the humerus are the second most common injury around the elbow in children. Treatment of patients presenting late is controversial. We report our experience of treatment of these fracture over last thirteen years in 78 children seen between 1987 and 2000. Average age- 5.2 years ; 53 patients presented early and 25 patients presented more than 3 weeks after injury . In latter, 11 patients were treated conservatively and rest by internal fixation. Pseudovarus was observed in 30% cases on long term followup. Of 25 patients presenting late, open reduction, internal fixation with bone grafting was carried out in eight cases (those who presented between 3–6 weeks) and rest of the 17 cases were kept under observation on regular follow up. At final follow up, the cases operated late (n= 8) had preservation of 70–80 % of Flexion Extension Arc. Of the 17 cases kept under observation, 8 (showing non union) developed cubitus valgus. 9 cases (showing malunion) continue to have stiff elbow . The elbow function was better in the former group. We suggest that every effort should be made to fix the lateral condylar fragment in patients presenting even more than 3 weeks especially if the metaphyseal chunk is large, the fragment is not widely displaced and rotated and the fracture is type II Milch in a very young child (as those patients rapidly develop very severe cubitus valgus deformity with translocation of ulna).
