A 16-year-old Malay boy presented to Kota Bharu Health Care Centre, Kelantan, with left shoulder pain after sustaining a fall. On further history taking, it was noted that the pain preceded the fall by 1 month. The early changes of osteosarcoma were visible on an X-ray during the initial presentation; however, this was missed by the primary care doctors. Three months later, the patient presented with persistent pain in the left shoulder and was diagnosed with osteosarcoma.

Background Neck shoulder pain (NSP) was highly prevalent even among the adolescents in previous Western studies. However, the prevalence among Korean adolescents was seldom studied and the factors associated with NSP were controversial. Methods: A self-administered questionnaire asking the presence of NSP, restriction in daily activities due to NSP, behavioral characteristics, and psychological factors was given to 1,232 adolescent enrolled in high schools. Finally, 1,194 providing adequate responses to the questionnaire were included. NSP occurring once a week or more over the last 6 months was defined as a significant NSP and the association between the significant NSP and the studied variables was estimated using multiple logistic regression analysis. Results: The prevalence of NSP and the significant NSP were 82.9% and 33.4%, respectively. The girls (40.6%) were experiencing the significant NSP more than the boys (26.0%). Restriction in daily activities due to NSP was very common and 74.8% of the girls and 65.2% of the boys reported study disturbance. The factors associated with higher risk significant NSP in the boys were higher BMI (25≥ kg/m2), moderate stress, and fairly poor or poor self-assessed physical condition with odds ratios (95% confidence intervals) of 1.86 (1.02∼3.40), 1.74 (1.03∼2.97), and 2.30 (1.26∼4.19), respectively. In the girls, a longer (>75% of total sitting time) time of sitting in desk/chair of the inadequate height was associated with a higher risk of the significant NSP (odds ratio: 1.59, 95% confidence interval: 1.05∼2.39). Conclusion: The prevalence of NSP in Korean adolescents was very high, suggesting that active efforts to prevent NSP in Korean adolescents would be needed with a consideration of different risk factors between girls and boys.

Shoulder is one of the most common sites of pain in outpatient clinic, and allows for almost unrestrained motion in all planes due to very unique anatomical structure. Detailed history taking and special physical examination based on basic anatomical and kinesiological knowledge are important for precise patient evaluation. Further radiographic and diagnostic laboratory test are required. Common causes of shoulder pain are adhesive capsulitis, impingement syndrome, rotator cuff tear, myofascial pain syndrome, and instability. Also cervical radiculopathy, lung, cardiac and abdominal problems should be considered as a cause of shoulder pain. Characteristics, physical examination tool, and treatment for common shoulder problems are described.
