Severe complex neglected infantile Blount disease acute correction by Ilizarov frame: A case report

Introduction: Blount disease is a disorder causing three proportions of deformity, including varus deformity, procurvatum deformity, and internal tibial rotational deformity. The standardized treatment remains controversial despite extensive reviews. The application of Ilizarov external fixators for circumspect corrections is established. The SCARE 2023 criteria have been followed in reporting the case report. Case presentation: We present the case of a nine-year-old girl who's complaining about bowing on both of her knees. From the examination, we found that the metaphyseodiaphyseal angle of both knees was 50 degrees. On the right knee, there is 125 degrees of procurvatum deformity and 115 degrees of deformity on the left knee. After performing deformity correction with the Ilizarov application, there's clinical improvement in the patient. Clinical discussion: Some experts advise using physeal distraction to manage the deformity in order to achieve correction. The limited popularity of physeal distraction technique may be attributed to the risks of premature closure of the growth plate that we manage to avoid. The Ilizarov frame provides maximum adjustability for aligning all planes, making it suitable for treating severe deformities. Secure fixation, improved patient mobility, being able to assess patient alignment in a functional standing position, and precision. Conclusion: Acute correction and fixation using circular frames as a treatment option for Blount disease show positive outcomes without any significant complications. © 2024 The Author(s)
