Summary
Shoulder pain is common in individuals with paraplegia (PP). This study found a low prevalence of rotator cuff tears but a high rate of distal clavicle osteolysis, linked to body mass index.
Area of Science:
- Orthopedics
- Rehabilitation Medicine
- Radiology
Background:
- Shoulder pain and rotator cuff tears are frequent concerns for individuals with paraplegia (PP).
- Understanding the specific prevalence of shoulder disorders in this population is crucial for targeted interventions.
Purpose of the Study:
- To investigate the prevalence of shoulder disorders, including rotator cuff tears and distal clavicle osteolysis, in individuals with paraplegia.
- To explore potential correlations between imaging findings, pain, and body mass index (BMI).
Main Methods:
- Recruited 28 individuals with paraplegia (mean age 35, mean 11.5 years post-injury).
- Utilized questionnaires for arm pain, physical examinations, plain radiographs, and magnetic resonance imaging (MRI).
Main Results:
- 36% of subjects reported shoulder pain in the preceding month.
- Only one rotator cuff tear was identified via MRI.
- Five subjects (18%) showed distal clavicle osteolysis on radiographs, with two cases being bilateral.
- A significant positive correlation was found between imaging abnormalities (radiographic and MRI) and body mass index (BMI).
- No direct relationship was observed between reported pain and imaging abnormalities.
Conclusions:
- Individuals with paraplegia exhibit a low prevalence of rotator cuff tears but a high prevalence of distal clavicle osteolysis.
- Subclinical shoulder abnormalities are present and correlate with higher BMI in this population.
- Further research may explore the clinical significance and management of these findings.
