Background: Shoulder pathologies are very common as the shoulder is the most mobile joint (and hence unstable) in the body. These conditions can lead to pain and disability that affect individuals socially and economically. Up to researchers' knowledge, epidemiological study of shoulder conditions attending orthopedic physical therapy outpatient clinics has not been carried out previously in Egypt. This study is to identify the prevalence and characteristics of shoulder pathologies in two main hospitals in two governorates in Egypt. Records were made for patients referred to orthopedic physical therapy outpatient clinics in two hospitals (Kasr Aini educational hospital) (KA) in Cairo and (Benha educational hospital) in Qalubiya Egypt, that are reviewed from the first of January 2019 to 31 December 2019. Demographic characteristics and types

were described.

Results: One year prevalence of shoulder pathologies was 6.1% (101/1633 cases). Male to female ratio was 1:2.6. The most frequent type of shoulder pathologies was impingement syndrome (38.6%), followed by rotator cuff tear (17,8%). Right side was most frequently affected (43.6%).

Conclusion: Shoulder impingement syndrome (SIS) and rotator cuff tear (RCT) were the two main types of shoulder pathologies among people living in Cairo and Qalubiya- Egypt.Concerning gender, higher prevalence was in women, and finally when considering the affected side, right side was commonly affected.
