Based on the surgical procedure, the patients were divided into two groups: the Ultrasound combined with x-ray arthrography-guided closed reduction and percutaneous pin fixation group (UA-CRPP) and the Open reduction percutaneous pin fixation group (ORPP). The UA-CRPP group underwent ultrasound-assisted closed reduction and internal fixation for Jakob Type II humeral lateral condyle fractures, with arthrography to assess the articular cartilage surface. The ORPP group underwent open reduction and Kirschner wire fixation for Jakob Type II humeral lateral condyle fractures. Demographic data, surgical time, clinical outcomes, complications, and radiographic data were recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 57 patients were included in both groups, with 37 males and 20 females. There were no significant differences between the two groups in terms of gender, age, weight, time from injury to surgery, follow-up time, injury side, or complications such as pin tract infection, deep infection, or intraoperative blood loss(\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;gt;\u20090.05). No cases of nonunion, refracture, or nerve injury were observed in either group. The surgical time and hospital stay were shorter in the UA-CRPP group compared to the ORPP group (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.05), and the radiological union time of fracture was shorter in the UA-CRPP group (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Ultrasound-assisted closed reduction and internal fixation is a feasible and effective treatment option for children with Jakob Type II humeral lateral condyle fractures.
