title: [Osteoarthrosis of upper extremity--basic conception and knack of diagnosis].
abstract: Joints of upper extremities are non weight-bearing joints. However, there are various diseases which cause pain in these joints with various frequencies. Elaborate movements of hand are the basis of many activities in daily life and reach function of elbow joint enables washing of faces and eating. Thus, pain in these joints hinders basic daily activities. There are only few cases that we treat as primary osteoarthrosis. Almost all cases are secondary osteoarthrosis which are caused by various trauma or diseases. It is very difficult and almost impossible to recover completely even with appropriate medical treatment once osteoarthrosis occurred. Therefore, it is important that we acknowledge those trauma and diseases which cause osteoarthrosis in these joints. It is also important to educate patients in order to prevent progression of osteoarthrosis.
