    Paraplegic men show significant axial skeletal changes, particularly in sacro-iliac joints, related to paralysis duration. These findings mimic HLA-B27 arthropathy but can be differentiated by para-osteoarthropathies.

    Area of Science:

    • Orthopedics
    • Rheumatology
    • Radiology

    Background:

    • Paraplegia can lead to various secondary health complications.
    • Axial skeletal changes are frequently observed in individuals with long-term paralysis.

    Purpose of the Study:

    • To investigate the prevalence and nature of axial skeletal changes in paraplegic men.
    • To explore the relationship between these changes and factors like paralysis duration, age, race, and level of paralysis.

    Main Methods:

    • Radiographic assessment of the axial skeleton (sacro-iliac joints and thoracolumbar spine) in 200 paraplegic men.
    • Analysis of skeletal changes including joint space narrowing, erosion, sclerosis, syndesmophytes, ossification, disk calcification, and osteophytes.

    Main Results:

    Related Experiment Videos

    • 42% of participants exhibited sacro-iliac (SI) joint changes, ranging from mild alterations to complete obliteration.
    • Thoracolumbar spine changes included syndesmophytes, interspinous ossification, disk calcification, and osteophytes.
    • Skeletal changes correlated with the duration of paralysis but not with race, age (except spine changes), or paralysis level.

    Conclusions:

    • The observed axial skeletal changes in paraplegics share similarities with HLA-B27-associated arthropathies.
    • Distinguishing these changes from other arthropathies can be aided by identifying para-osteoarthropathies and negative HLA-B27 status.
