| Summary: | Background:. Two surgical approaches, an anterolateral and a posterolateral approach, have been advocated for lateral condylar fractures (LCFs) of the humerus in children. The purpose of this study was to evaluate the radiographic and clinical outcomes of the 2 surgical approaches.
Methods:. We retrospectively analyzed the data of consecutive patients <15 years of age with an LCF treated via open reduction and internal fixation through 1 of 2 surgical approaches during the period of April 2000 to March 2019. Patients were classified into the anterolateral (AL) and posterolateral (PL) groups, according to the surgical approach used. Postoperative complications and radiographic and clinical findings (including range of motion and findings on the basis of the Flynn criteria) were investigated. To investigate humeral deformity, the Baumann angle and the carrying angle were measured on anteroposterior radiographs.
Results:. Sixty-one of 82 patients met the inclusion criteria. The AL group included 17 patients (13 male, 4 female), and the PL group included 44 patients (28 male, 16 female). In the PL group, 7 patients had cubitus varus deformity, 3 had malunion due to unacceptable reduction of fracture fragments, and 6 had elbow joint contracture. In the AL group, the overall clinical results were excellent for 15 patients and good for 2. In the PL group, the clinical results were excellent for 12 patients, good for 14, fair for 6, and poor for 12.
Conclusions:. An anterolateral approach would be the optimal approach for an LCF in pediatric patients.
Level of Evidence:. Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
