Summary
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:
- 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.
