Hemarthrosis意思

"Hemarthrosis" is a medical term that refers to the bleeding into a joint cavity, which results in the accumulation of blood (hemorrhage) within the joint space. It is a type of hematoma that specifically affects synovial joints, which are the most common type of joint in the body and include areas such as the knees, elbows, and ankles.

Hemarthrosis can occur due to various causes, including trauma, bleeding disorders (such as hemophilia), or the side effect of certain medications. In people with bleeding disorders, hemarthrosis can occur even with minor trauma or injury, as the blood does not clot properly, leading to uncontrolled bleeding.

Symptoms of hemarthrosis include pain, swelling, and stiffness in the affected joint, as well as limited range of motion. Diagnosis is typically made through physical examination and imaging tests, such as X-rays or MRI scans, which can reveal the presence of blood within the joint.

Treatment for hemarthrosis depends on the underlying cause and may include measures to stop the bleeding, such as the administration of clotting factors in cases of bleeding disorders, as well as supportive care to reduce pain and inflammation. In some cases, surgical intervention may be necessary to drain the blood from the joint and repair any damage.
