Abstract

INTRODUCTION: Displaced supracondylar fracture of humerus in children is commonly treated by closed or open reduction and reduction held by kirschner wires. Biomechanically cross pinning is superior than lateral pinning but there is a risk of ulnar nerve injury. Recent studies suggest lateral pinning if properly done has equal stability and there is no risk of ulnar nerve injury. AIM OF STUDY: To compare the cosmetic and functional outcome of displaced supracondylar fracture humerus in children treated with cross pinning and lateral pinning. MATERIALS & METHODS: Inclusion Criteria: Type II, Type III gartland fractures, Fractures treated by closed or open reduction, Age less than 15 years. Exclusion Criteria: Type I Gartland Fractures, Age more than 15 years. In cross pinning precautions were taken to protect ulnar nerve in closed reduction. In lateral pinning 2 or 3 wires placed in divergent or parallel configuration. The cosmetic and functional outcomes were done by flynns criteria. RESULTS: All 9 cross pinning patients had satisfactory results. All 12 cross pinning patients had satisfactory results. There was a single case of ulnar nerve injury in cross pinning group and no such case in lateral pinning group. CONCLUSION: Cross pinning is the most stable configuration where as lateral pinning is equally stable configuration in maintaining the reduction of displaced supracondylar fractures of humerus in children. Cross pinning has a definitive risk of iatrogenic ulnar nerve injury where as there is no risk of ulnar nerve injury in lateral pinning.
