The periosteum: its function reassessed.

A L Eyre-Brook

    Clinical Orthopaedics and Related Research
    |October 1, 1984
    PubMed
    Summary

    The periosteum is crucial for bone healing, acting as a scaffold and blood vessel source. Its integrity is vital for fracture union, especially in untreated cases or after surgical removal.

    Area of Science:

    • Orthopedics
    • Regenerative Medicine
    • Surgical Innovation

    Background:

    • The periosteum's role in bone regeneration has been debated since early 20th-century studies.
    • Clinical observations, particularly from developing countries, offer insights into periosteal function in fracture healing.
    • Understanding periosteal mechanics is essential for effective fracture management and reconstructive surgery.

    Purpose of the Study:

    • To review experimental evidence on the periosteum's function in bone repair.
    • To clarify the periosteum's role in fracture union and revascularization.
    • To highlight the clinical implications of periosteal integrity in various orthopedic conditions.

    Main Methods:

    • Review of historical and contemporary experimental studies on periosteal function.
    • Analysis of clinical data related to fracture healing and untreated bone defects.
    • Examination of the periosteum's contribution to mechanical stability and vascular supply.

    Main Results:

    • Periosteum requires contact with a hematoma and bone to exhibit osteogenic properties.
    • The periosteum serves as a critical mechanical link between bone fragments in fractures.
    • Periosteal continuity is essential for revascularization, and its loss can lead to fibrous union.
    • Extensive periosteal destruction in untreated osteomyelitis results in significant bone segment loss.

    Conclusions:

    • The periosteum is indispensable for successful fracture healing, providing both structural support and vascularization.
    • Techniques that compromise periosteal integrity, such as total excision, impede new bone formation.
    • Clinical outcomes underscore the importance of preserving the periosteum in fracture treatment and managing bone defects.
