Spinal changes in idiopathic chondrocalcinosis articularis

A J Richards, E B Hamilton

    Rheumatology and Rehabilitation
    |August 1, 1976
    PubMed
    Summary

    Idiopathic chondrocalcinosis articularis (a joint disorder) can affect the lumbar spine, with disc calcification seen in 31% of patients. This spinal involvement was linked to older age and peripheral joint disease, not back pain.

    Area of Science:

    • Rheumatology
    • Radiology
    • Orthopedics

    Background:

    • Idiopathic chondrocalcinosis articularis is a condition affecting joints.
    • Spinal involvement, particularly disc calcification, is less understood.

    Purpose of the Study:

    • To investigate the prevalence and characteristics of lumbar spine disc calcification in patients with idiopathic chondrocalcinosis articularis.
    • To explore associations between disc calcification and patient demographics, peripheral joint involvement, and spinal symptoms.

    Main Methods:

    • Retrospective review of lumbar spine radiographs from 67 patients diagnosed with idiopathic chondrocalcinosis articularis.
    • Analysis of disc calcification, peripheral joint chondrocalcinosis, and presence of destructive arthropathy.
    • Comparison with patients without disc calcification and control groups.

    Main Results:

    • Disc calcification was identified in 31% of patients, predominantly at the L2-3 level.
    • Patients with disc calcification were significantly older and had a higher incidence of peripheral joint chondrocalcinosis.
    • No association was found between disc calcification and back pain or spinal stiffness.
    • Destructive spinal changes were observed in a subset of patients with disc calcification and peripheral arthropathy.

    Conclusions:

    • Lumbar spine disc calcification is a notable feature in idiopathic chondrocalcinosis articularis, particularly in older individuals with peripheral joint disease.
    • While not directly linked to pain, spinal calcification may coexist with destructive arthropathy in some patients.
    • Further research is warranted to understand the clinical significance and progression of spinal chondrocalcinosis.
