Staged femoral lengthening

E J Eyring

    Clinical Orthopaedics and Related Research
    |October 1, 1978

    Summary

    Serial lengthening of short femurs can correct significant leg length discrepancies, offering a cost-effective solution. While complications like plate fractures can occur, they often facilitate further lengthening, minimizing issues.

    Area of Science:

    • Orthopedic Surgery
    • Pediatric Orthopedics
    • Limb Reconstruction

    Background:

    • Limb length discrepancy, particularly in the femur, presents significant challenges in pediatric and adult patients.
    • Traditional methods for correcting femur shortening may be invasive or costly.

    Observation:

    • Serial lengthening, involving multiple small increments (approx. 1 inch each), was performed on short femurs.
    • Up to five lengthening procedures were conducted on individual femurs.

    Findings:

    • Good results were achieved for femur shortening secondary to epiphyseal injury (e.g., distal femur osteomyelitis).
    • Congenital shortening correction was limited by hip subluxation during lengthening.
    • Fracture through the plate and graft was the primary complication, often serving as an indication for further lengthening.

    Implications:

    • Serial lengthening offers a potentially cost-effective and time-efficient approach for significant femur shortening.
    • The technique appears to avoid catastrophic complications, making it suitable for private patient care.
    • Careful patient selection is crucial, as the procedure is not recommended for minor leg length discrepancies.
