Hypothesis
Anthropometric differences would be observed between genders and age groups, and the detection of bicipital spurs would be lower on 2D axial CT compared to 3D reconstructed images.
Conclusion
3D-CT is more effective in detecting bicipital spurs, which are more common in older individuals, and the bicipital groove is narrower in this group.
Supporting Evidence
- 3D-CT detected biceps spurs in 54% of cases compared to 42.3% with 2D-CT.
- Spur incidence was significantly greater in older patients (60.3% vs. 45.8%).
- The average groove width was narrower in older adults (p = 0.006).
- Men had a wider and deeper bicipital groove than women (p = 0.000).
- The average height of the medial spur was greater in men (p = 0.039).
Takeaway
Doctors used special 3D pictures to find bumps in the shoulder area that can cause pain, and they found more bumps in older people.
Methodology
The study analyzed 3D-CT scans of 111 patients to evaluate bicipital groove morphology and spur formation, comparing results with 2D-CT images.
Potential Biases
Participants were not asymptomatic, which may affect the generalizability of the findings.
Limitations
The study was retrospective, had a small sample size, and did not analyze biceps pathologies.
Participant Demographics
Mean age of participants was 55.4 years, with 48 patients under 55 and 63 patients 55 and older.
Statistical Information
P-Value
p = 0.006 for groove width difference by age
Statistical Significance
p<0.05
