Compression plate position. Extraperiosteal or subperiosteal?

A H Alexander, H E Cabaud, J O Johnston

    Clinical Orthopaedics and Related Research

    Summary

    Subperiosteal versus extraperiosteal surgical exposure for long bone fracture fixation showed no difference in healing quality. Subperiosteal exposure is preferred to minimize soft tissue injury during compression plate fixation.

    Area of Science:

    • Orthopedic surgery
    • Veterinary medicine
    • Biomedical engineering

    Background:

    • Compression plate fixation is a standard treatment for diaphyseal long bone fractures.
    • The optimal surgical approach and plate placement relative to the periosteum remain debated.
    • Understanding healing differences between subperiosteal and extraperiosteal techniques is crucial for surgical decision-making.

    Purpose of the Study:

    • To compare the quality and chronology of fracture healing between subperiosteal and extraperiosteal compression plate fixation.
    • To evaluate the biomechanical properties of healed fractures using both surgical techniques.
    • To determine if surgical approach influences fracture healing outcomes in dogs.

    Main Methods:

    • Adult dogs with radial and ulnar diaphyseal fractures underwent compression plate fixation.

  • One limb received extraperiosteal plate placement, while the contralateral limb had subperiosteal placement.
  • Histologic, radiographic, and biomechanical analyses were performed to assess fracture healing.

    • Main Results:

    • No statistically significant differences were observed in radiographic or histologic assessments of healing between the two groups.
    • Biomechanical testing revealed no significant variations in load, stress, modulus of elasticity, or strain parameters.
    • Both subperiosteal and extraperiosteal exposures resulted in comparable fracture healing outcomes.

    Conclusions:

    • Surgical exposure technique (subperiosteal vs. extraperiosteal) does not significantly impact the healing of diaphyseal long bone fractures treated with compression plating in dogs.
    • Subperiosteal exposure is recommended due to a lower risk of surrounding soft tissue injury.
    • This finding supports the use of subperiosteal techniques for improved patient outcomes in fracture repair.
