Introduction: Around 60% of all the elbow injuries in the first decade, supracondylar fractures of the humerus are the most widely recognized elbow injuries in youngsters. Accompanied with problems like compartment disorder, neurovascular harm, Volksman's ischemic contracture, and malunion. The most widely recognized choice of pinning is either cross-pin fashion or two parallel pins. Closed reduction and percutaneous K-wire fixation are best with the least problems in contrast with different modalities. In our study, we want to assess the functional and radiological outcome of pediatric displaced supracondylar humerus fracture treated with closed reduction percutaneous K-wire fixation. Materials and methods: Sixteen patients were selected for the study based on the inclusion and exclusion criteria based on the consecutive sampling. For all patients, the standard technique of percutaneous k wire fixation was performed, and patients were evaluated on 6 weeks, 3 months, and 6 months with functional scoring by Flynn et al. Criteria and Mayo elbow scoring and radiological scoring with Baumann's angle. Results: Ten children (62.5%) were affected in their first decade of life, with a clear male predilection than females. Mayo elbow scoring was 2.5, 6.0, and 3.75 at 6 weeks, 3 months, and 6 months. Pin-tract infection (4), two cases of malunion of our study population. In all 16 cases, the union was achieved with 14 cases satisfactorily excellent and satisfactorily good in 1 case and unsatisfactorily poor in 1 case. Conclusion: Closed reduction and percutaneous pinning are the treatment of choice for pediatric supracondylar humerus fractures with Modified Gartland's type II and type III. Appropriate pinning technique ensures a successful outcome with cross configuration providing excellent outcome with good rotational stability. Closed reduction and percutaneous pinning is a safe, cost-effective, less morbid procedure.
