Background: A sufficient background and careful initial clinical evaluation are needed for the assessment and treatment of the supracondylar fracture of the humerus. The study aimed to evaluate the results of cross lateral ascending and descending pinning in pediatric supracondylar fractures humerus. Patients and methods: This study included 18 children with supracondylar humerous fractures who underwent lateral pinning in the pediatric department, the hospitals of Zagazig University, and the hospital of teaching Ibnsina. Surgical technique was performed and outcomes were recorded. Results: Regarding cosmetic score, more than half of the studied group (55.6%) had excellent, (27.7%) of them had good and (11.1%) had fair and (5.6%) had poor cosmetic score respectively. Concerning Flynn's Score, more than half of the studied group (55.6%) had excellent functional outcome, (27.7%) of them had good functional outcome and (11.1%& 5.6%) had fair and poor functional outcome respectively.There was statistically significant difference between patients with satisfactory and unsatisfactory outcome regarding presence of complications and mechanism of injury with better outcome in injury due to FD and patients with satisfactory outcomehad no complications. Conclusion: Near manipulation and percutaneous attachment in the paediatric age group is an appropriate and conclusive treatment procedure with two crossing-lateral K wire of Gartland type II and III supracondylar fractures with less complications.
