The patient will then undergo closed reduction percutaneous pinning of supracondylar humerus fracture. Final AP and lateral fluoroscopic images in the case will be taken. The patient will be discharged from the hospital when pain is controlled with standard oral pain medications and all goals of inpatient management have been achieved. No patients will receive post-operative antibiotics regardless of randomization group as is the existing standard of care. Patients will be scheduled to follow up in 3-6 weeks depending on age. At that time the cast will be removed and AP and lateral radiographs will be used to assess healing. The pins will be removed in clinic and a soft dressing applied to the elbow region.
