Calcaneal cysts. A radiological and anatomico-pathological study.

D Van Linthoudt, R Lagier

    Acta Orthopaedica Scandinavica
    |June 1, 1978
    PubMed
    Summary

    This study examined calcaneal cysts in young patients, revealing two key histological features: hemorrhage signs and new bone formation. These findings suggest calcaneal cysts may arise from local bleeding within the calcaneus bone.

    Area of Science:

    • Orthopedic pathology
    • Radiology
    • Pediatric bone disorders

    Background:

    • Calcaneal cysts are uncommon bone lesions.
    • Understanding their etiology is crucial for diagnosis and treatment.
    • Previous studies have not fully elucidated the histological characteristics and radiological appearance of these specific cysts.

    Purpose of the Study:

    • To investigate the radiological and anatomico-pathological features of calcaneal cysts in young patients.
    • To identify the key histological characteristics of the cyst wall.
    • To correlate histological findings with the typical radiological appearance.

    Main Methods:

    • Retrospective analysis of 17 cases of calcaneal cysts in young patients.
    • Radiological imaging review.
    • Detailed anatomico-pathological examination of cyst wall histology.

    Main Results:

    • Two primary histological features were identified: hemosiderin deposits with giant cell reaction (indicating prior hemorrhage) and newly formed bone on existing trabeculae.
    • The newly formed bone contributes to the characteristic radiological appearance of the cysts.
    • The findings suggest a possible origin from local hemorrhages in the trigonum calcis.

    Conclusions:

    • Calcaneal cysts in young patients exhibit distinct histological features related to hemorrhage and bone apposition.
    • These features explain the typical radiological presentation.
    • Local hemorrhages within the calcaneus may be the underlying cause of these uncommon cysts.
