The Medial Elevation Osteotomy for Late-presenting and Recurrent Infantile Blount Disease.

J Pediatr Orthop 2021 Feb;41(2):67-76

Department of Orthopaedic Surgery, School of Clinical Medicine, University of KwaZulu-Natal, KwaZulu-Natal, South Africa.

Background: Late-presenting or recurrent infantile Blount disease (IBD) is characterized by knee instability because of medial tibial plateau depression, multiplanar proximal tibial deformity, and potential distal femoral deformity. The surgical treatment strategy includes medial elevation osteotomy to stabilize the knee, together with proximal tibial osteotomy to correct alignment, and lateral epiphysiodesis to prevent a recurrence. This study's primary aim was to describe the clinical outcomes of medial elevation osteotomy for the management of late-presenting and recurrent IBD. Read More

J Pediatr Orthop 2021 Jan;41(1):e36-e43

Department of Orthopaedic Surgery, School of Clinical Medicine, University of KwaZulu-Natal, Msunduzi, South Africa.

Background: This study aimed to determine the recurrence rate in infantile Blount disease (IBD) in a cohort of patients treated with a tibial osteotomy; and also to identify which factors were associated with recurrence.

Methods: We reviewed the records of 20 patients, under the age of 7 years, with IBD (35 involved extremities) treated by proximal tibial realignment osteotomy to physiological valgus at a single institution over 4 years. We then analyzed the data to determine the rate of recurrence and identify the risk factors for recurrence. Read More

Guided Growth with Hemiplateau Elevation as an Alternative to Epiphysiodesis for Treatment of a Young Patient with Advanced Infantile Blount Disease: A Case Report.

JBJS Case Connect 2020 Jul-Sep;10(3):e1900643

1Western Michigan University Homer Stryker M.D. School of Medicine, Kalamazoo Michigan 2Department of Orthopaedic Surgery, Western Michigan University Homer Stryker M.D. School of Medicine, Kalamazoo Michigan 3Department of Biomedical Science, Western Michigan University Homer Stryker M.D. School of Medicine, Kalamazoo Michigan.

Case: Infantile Blount disease results from deceleration of growth by the proximal posteromedial tibial physis causing tibia vara. In advanced disease stages, surgical treatment is indicated. Owing to the young age and advanced Langenskiöld stage in this patient, a novel technique was performed combining lateral proximal physeal tethering with medial hemiplateau elevation osteotomy to correct the articular surface and unload the medial proximal tibial physis.

Idiopathic Genu Valgum and Its Association With Obesity in Children and Adolescents.

J Pediatr Orthop 2019 Aug;39(7):347-352

Shriners Hospitals for Children.

Background: Obesity as a cause of lower extremity deformity in children has been well established. This deformity is most often seen as tibia vara, however, at our institution we have observed more obese children and adolescents over age 7 years with excessive or progressive idiopathic genu valgum. Our hypothesis is that children with idiopathic genu valgum have high rates of obesity which impact the severity of their disease. Read More
