Deformity Reconstruction Surgery for Blount's Disease

Area of Science:

• Orthopedics
• Pediatric Orthopedics
• Skeletal Dysplasias

Background:

• Blount's disease is an idiopathic developmental abnormality of the proximal medial tibia physis.
• It leads to tibia varus and other multi-planar deformities, with multifactorial causes including genetics, mechanical, and developmental factors.
• Associated factors include vitamin D deficiency, early walking, and obesity, with distinct early-onset and late-onset presentations.

Purpose of the Study:

• To review the fundamental concepts of Blount's disease.
• To delineate various reconstructive surgical treatment strategies for Blount's disease.

Main Methods:

• Literature review of Blount's disease concepts and surgical management.

Main Results:

• Blount's disease presents in early-onset (often bilateral) and late-onset (juvenile and adolescent) forms.
• Deformities include tibia varus, procurvatum, internal torsion, and limb length discrepancy, potentially leading to knee arthritis and gait issues if untreated.
• Surgical options are tailored to patient factors and include guided growth, osteotomies, physeal procedures, and external fixation.

Conclusions:

• Surgical goals include restoring alignment, equalizing limb lengths, and preventing recurrence.
• Treatment strategies vary based on patient age, weight, and deformity severity.
• Effective surgical management is crucial for long-term outcomes in Blount's disease.
