Abstract: Aim: Evaluate the technical factors influencing the stability of percutaneous lateral pinning Patients and methods: This was a descriptive, retrospective, and longitudinal study conducted in the Department of Pediatric Orthopedic and Traumatology at Béchir Hamza Children's Hospital in Tunis from January 1, 2014, to December 31, 2019, involving 573 children under the age of 14 who underwent surgical treatment for supracondylar elbow fractures. Results: The mean age was 5.03 ± 2.64 years. The gender ratio was 1.46. The fracture line was located in zone 4 in 325 cases. The entry level of the most medial pin corresponded to zones 2 and 3 in 28.4% each. Convergence analysis revealed convergent pins in 42.4%. The exit level of the lateral pin was between zone -1 and 1 in 66% of cases. The exit analysis of the medial pin corresponded to zone -2 in 43.1% of cases. In the sagittal plane, the entry level of the most anterior pin corresponded to zone 4 in 49.4% of cases. The entry of the lateral pin tended to be more medial for lower fracture lines. The position of the first pin, whether lateral or medial, influenced the placement of the second pin. The risk of secondary translation when pins converged in the coronal plane was multiplied by 1.7 (p=0.02). Regarding posterior tilting, it was multiplied by 2.21 for stage 4 fractures. The risk of secondary rotational displacement was multiplied by 4 for stage 4, by 4.08 for exit levels of the medial pin <-2, by 1.5 for convergent pins, and 4.5 for inter-pin distances <1/3 of the fracture line. Conclusion: Our study showed that the divergent configuration was the most stable. Based on our results and those in the literature, we suggest a more medial entry zone for the lateral pin and a higher exit zone for the lateral pin.
