Summary

The Sofield-Millar operation on long bones showed that more than three osteotomies significantly prolonged bone healing and caused thinning. A modified technique minimizes trauma and devascularization for better outcomes.

Area of Science:

  • Orthopedic surgery
  • Pediatric orthopedics
  • Bone healing

Background:

  • The Sofield-Millar operation is a surgical procedure for correcting long bone deformities.
  • Multiple osteotomies in this procedure can lead to complications such as delayed union and bone thinning.
  • Minimizing surgical trauma and devascularization is crucial for successful bone healing.

Purpose of the Study:

  • To evaluate the impact of the number of osteotomies on bone healing after the Sofield-Millar operation.
  • To present a modified surgical technique aimed at reducing complications.
  • To assess the efficacy of the modified technique in improving bone union and minimizing bone thinning.

Main Methods:

  • Review of 58 long bone cases treated with the Sofield-Millar operation in ten patients.

  • Statistical analysis to determine the correlation between the number of osteotomies and bone healing time/bone thickness.
  • Implementation and evaluation of a modified surgical technique using image-intensifier guidance and minimal surgical exposures.

    • Main Results:

    • Performing more than three osteotomies significantly prolonged the time to bone union (p < 0.001).
    • A significant correlation was found between multiple osteotomies and bone thinning (p < 0.02).
    • The modified technique, involving image-intensifier controlled rod introduction and limited osteotomies, aims to minimize surgical trauma and devascularization.

    Conclusions:

    • Limiting the number of osteotomies is critical for successful bone union and maintaining bone integrity in the Sofield-Millar operation.
    • The modified surgical technique offers a promising approach to minimize complications associated with this procedure.
    • Further studies are warranted to fully validate the long-term benefits of the modified technique.
