Percutaneous proximal tibial osteotomy for Blount

Area of Science:

  • Orthopedic Surgery
  • Pediatric Orthopedics
  • Limb Deformity Correction

Background:

  • Blount's disease is a growth disorder affecting the proximal tibia.
  • Tibial osteotomy is a surgical procedure to correct angular deformities.
  • External fixators are commonly used for post-operative stabilization and correction.

Purpose of the Study:

  • To evaluate changes in tibial and overall limb length after percutaneous proximal tibial osteotomy with acute angular correction in pediatric Blount's disease patients.
  • To compare actual limb length changes with predicted changes based on preoperative measurements.

Main Methods:

  • Retrospective review of twelve male patients (aged 11-17 years) with unilateral Blount's disease.
  • Analysis of preoperative and healing radiographs to measure tibial and overall limb length.

  • Comparison of angular correction achieved versus predicted limb length increase.

    • Main Results:

    • Angular correction increased overall limb length by a mean of 1.4 cm.
    • The actual limb length increase was, on average, 0.7 cm less than predicted.
    • A significant finding was tibial shortening, which contributed to the discrepancy between actual and predicted limb length.

    Conclusions:

    • Percutaneous proximal tibial osteotomy with acute angular correction can increase overall limb length in Blount's disease.
    • Tibial shortening is a factor that reduces the expected limb length gain after this procedure.
    • Surgeons should consider potential tibial shortening when planning corrective osteotomies for Blount's disease to manage limb length expectations accurately.
