Functional Outcome of Displaced Pediatric Lateral Condyle Humerus Fractures Treated by Closed Reduction and Percutaneous Pinning

摘要

BACKGROUND: Open reduction and internal fixation is an ideal treatment for displaced unstable lateral condyle fractures. Very few studies have focused on the closed reduction and percutaneous pinning (CRPP) of displaced lateral condyle fractures in children. This prospective non-randomized study aims to evaluate the functional outcome of CRPP for minimally displaced as well as displaced lateral condyle fracture except completely rotated fractures to evaluate the functional and radiological outcomes. METHODS: The fractures were classified according to the Song et al classification system based on the pattern and displacement of fractures. Stage II , III and IV lateral condyle fractures were included excluding Stage I and V. Twenty patients were finally enrolled in the study. Fractures were reduced under C arm by varus and longitudinal traction force and fixed with 2 or 3 parallel K wires. Functional outcomes were evaluated according to the Hardacre et al scores. RESULTS: The Average age of patient in this study was 7.82±2.21 years with 13 (65%) of male and 7 (35%) of female. There were 12 (60%) fractures in left side and 8 (40%) in right side. 11 (55%) of fractures caused by fall during playing. Time taken for the fracture to unite was 6.3±1.2 weeks. There were 17 (85%) of excellent and 3 (15%) of good results according to the Hardacre et al scores. CONCLUSION: Closed reduction and percutaneous pinning can be tried successfully in minimally displaced unstable as well as displaced unstable lateral condyle fractures with excellent functional outcomes provided the good assessment of pattern and displacement of fractures by internal oblique views.
