Background and aim: External humeral condyle fracture associated with a posteromedial elbow dislocation is a very rareentity, of which there are very few cases published. Our objective is to present a complex case treated in our Hospital, thediagnosis, the treatment we chose, and the follow-up at 9 weeks after the intervention. Clinical case: 5-year-old boy with aposteromedial elbow dislocation associated with an external humeral condyle fracture, which was diagnosed by CT andtreated surgically using an anterior approach over the elbow, open reduction, and osteosynthesis with K-wires. Results:clinical and radiological results 9 weeks after the intervention were excellent, presenting a radiographic consolidation ofthe fracture and an excellent range of joint mobility. Conclusion: early diagnosis and surgical treatment through openreduction and osteosynthesis of the external condyle is the gold standard on treatment for these injuries, since a badreduction leads to poor long-term results.
