Abstract

Introduction: Lateral condyle fractures of the humerus are among the most common elbow fractures in children, accounting for approximately 10-20% of pediatric elbow fractures. If not managed appropriately, these injuries may lead to complications that impair elbow function. Surgical fixation using cancellous screws has been considered an effective treatment modality; however, there is a paucity of research on this technique in the Vietnamese clinical setting.

Objective: To evaluate short term results of bone fixation using cannulated screws in the treatment of lateral humeral condyle fractures in children.

Method: A retrospective descriptive study was conducted on 32 pediatric patients, aged 1 to under 16 years, diagnosed with lateral condyle fractures of the humerus classified as Jakob type II or III. All patients underwent open reduction and internal fixation with cancellous screws at the Ho Chi Minh city Orthopedic and Traumatology Hospital, between 2018 and 2020. The minimum follow-up period was 6 months. Outcomes were assessed using the Hardacre criteria and elbow range of motion recovery (flexion, extension, flexion - extension arc).

Results: The mean age was 5.37 ± 1.34 years, with 84.38% of cases occurring in children aged 1-10 years. Males accounted for 65.63% of the sample. Domestic accidents were the leading cause of injury (78.12%). Postoperative outcomes showed that 87.5% of patients had excellent results and 12.5% had good results according to Hardacre’s criteria, with no poor outcomes recorded. The complication rate was low, with no cases of nonunion or avascular necrosis reported.

Conclusion: Open reduction and internal fixation of pediatric lateral humeral condyle fractures using cancellous screws yielded favorable functional outcomes with minimal complications. Early diagnosis and appropriate surgical intervention are crucial for optimizing recovery and minimizing long-term sequelae.
