Background: The present study was conducted to compare the effectiveness of lateral pinning and cross pinning in the management of supracondylar fractures in humerus in children. Method: A total of 30 cases of children with Type II, Type IIIA and Type IIIB Gartland Classification supracondylar fracture of humerus were selected by consecutive sampling. Out of 30, 15 were included in the lateral pinning group and other 15 were included on the cross pinning group. Outcome measures that were used to compare and evaluate the outcome of treatment were: Flynn's criteria for functional outcome, ASK-p (Activities Scale for Kids-performance version), Loss of carrying angle and range of motion. Results: Both the lateral pinning group and cross pinning group showed similar functional outcome, ASK-p score, loss of carrying angle and range of motion with no statistically significant difference. The lateral pinning method showed no iatrogenic ulnar nerve injury but there were 2 cases of iatrogenic ulnar nerve injury with the cross pinning method Conclusion: Both the lateral and cross pinning methods showed successful management of supracondylar fracture of humerus in children with a few iatrogenic ulnar nerve injuries with the cross pinning method.
