Infantile tibia vara is a growth disturbance causing progressive leg deformities. Early diagnosis and the Langenskiöld classification guide treatment, ranging from bracing to surgery for severe cases.

Area of Science:

  • Orthopedics
  • Pediatric Orthopedics
  • Radiology

Background:

  • Infantile tibia vara, a rare condition, causes progressive deformities if not diagnosed early.
  • Key radiographic findings include medial tibial metaphyseal beaking and fragmentation.
  • Etiology is an acquired growth disturbance, not avascular necrosis.

Purpose of the Study:

  • To review the diagnosis, classification, and treatment of infantile tibia vara.
  • To highlight the utility of the Langenskiöld classification and the modified Deformity Angle (MDA) for assessing angular deformities.

Main Methods:

  • Review of radiographic findings, including medial tibial metaphyseal beaking and fragmentation.
  • Application of the Langenskiöld six-stage classification for staging disease severity.

  • Utilizing the modified Deformity Angle (MDA) for reproducible angular deformity measurement.

    • Main Results:

    • The Langenskiöld classification aids diagnosis, prognosis, and treatment planning.
    • The MDA is a reproducible method for measuring angular deformities in both infantile and adolescent tibia vara.
    • Treatment varies from observation/bracing (Stages I-II) to corrective osteotomy (Stages III-IV) and complex surgical interventions (Stages V-VI).

    Conclusions:

    • Early diagnosis and appropriate staging are crucial for managing infantile tibia vara.
    • Treatment strategies should be tailored to the disease stage and patient age.
    • The adolescent form, though less common, often requires surgical intervention for significant genu varum.
