High cost of ancillary procedures has been a common complaint by patients presenting with shoulder pain. Lost work hours likewise contribute to the burden in terms of cost. A systematic review on the prevalence and incidence of shoulder pain reported that shoulder pain is common with a one-year prevalence reported up to 47% in a general population (Luime et al, 2004 and Miranda et al, 2005).
Magnetic Resonance Imaging (MRI) has been a common practice in some developed countries in the diagnosis of shoulder pathology. However, in developing countries including Philippines, a significant proportion of the population cannot afford the examination cost. Alternative modalities like x-ray and ultrasound remained the most common modalities requested by clinicians. Though these modalities have lesser sensitivity and specificity compared to MRI, they are still the preferred initial diagnostic imaging modalities in the assessment of shoulder pain. Despite the high diagnostic imaging utilization at De La Salle University Medical Center (DLSUMC), a few studies show the role of x-ray and ultrasound in the assessment of shoulder pain. The lack of baseline data on the diagnostic performance of x-ray and ultrasound in the assessment of shoulder pathology among patients complaining of shoulder pain has prompted the author to conduct this investigation.
To determine the agreement between radiographic and sonographic findings among patients with shoulder pain at De La Salle University Medical Center.
1. To determine the demographic and clinical characteristics of patients with shoulder pain in terms of age, sex and laterality of shoulder pain.
2. To determine the proportion of subjects with radiographic and sonographic findings.
3. To determine whether there is a significant difference in the proportion of subjects with radiographic findings and sonographic findings.
4. To determine the common radiographic and sonographic findings seen among patients with shoulder pain.
5. To determine the common sites and anatomic changes among patients with shoulder pain as seen on x-ray and ultrasound.
6. To determine the common findings detected by x-ray and were not detected by ultrasound and vice versa
