The calcar femorale redefined

J B Griffin

    Clinical Orthopaedics and Related Research

    Summary

    The calcar femorale, a unique bone spur in the femur, influences peritrochanteric fracture patterns. Understanding its distinct structure is crucial for accurate diagnosis and treatment in orthopedic surgery.

    Area of Science:

    • Orthopedic Surgery
    • Radiology
    • Anatomy

    Background:

    • The calcar femorale is a distinct anatomical feature of the proximal femur.
    • Its unique structure and location are critical for understanding femoral biomechanics.
    • Accurate identification of the calcar femorale is essential for interpreting complex fractures.

    Purpose of the Study:

    • To describe the anatomical characteristics of the calcar femorale.
    • To elucidate its role in the configuration of peritrochanteric fractures.
    • To differentiate the calcar femorale from the medial compression buttress.

    Main Methods:

    • Radiographic analysis of the proximal femur.
    • Detailed anatomical description based on imaging.
    • Comparison with existing anatomical landmarks.

    Main Results:

    • The calcar femorale is a medial bone spur, thickest centrally and thinning laterally.
    • Optimal visualization occurs on X-ray views perpendicular to the femoral neck's neutral axis.
    • The calcar femorale's presence impacts the morphology of peritrochanteric fractures.

    Conclusions:

    • The calcar femorale is a significant anatomical landmark affecting fracture patterns.
    • Radiographic interpretation requires distinguishing the calcar femorale from the medial buttress.
    • A clear understanding of the calcar femorale aids in surgical planning for femoral fractures.
