Intraarticular bleeding and muscle bleeding occur spontaneously or as a result of trauma in hemophilia A or B. The most common sites for hemarthrosis are the knees joints, elbows and ankles joints. Resorption of intraarticular blood induces reactive hemophilic synovitis. ⋯ Radiosynoviorthesis (RSO), which is an alternative in certain cases, has been performed with great success in 12 cases in our hospital. In advanced arthropathy joint mobilization should be the emphasis of the physical therapy. Bandages, crutches and ortopaedic shoe devices improve the walking capacity.

Patients suffering from von-Willebrand-disease or hemophilia A or B are the most common patients with coagulation disorders in orthopedic hospitals. Patients suffering from hemophilia A or B are treated with pure factor VIII or IX concentrates. We prefer recombinant products. ⋯ Typical presentation of these patients is the uncontrollable bleeding during an operation; typical is also the bleeding from mucous membranes. Patients with mild disorders are treated with DDAVP. Patients suffering from type 3 need substitution therapy with von-Willebrand-factor containing concentrates (for example Humate P).

The von Willebrand's Disease affects about 1-3% of the population and it is undiagnosed in most people. Originally described by the Finish physician Erik von Willebrand in 1926 this disorder is associated with mucous membrane bleeding including epistaxis, hypermenorhoea and excessive bleeding from surgery and dental procedures. In von Willebrands disease the patients have a quantitative or qualitative abnormality in the von Willebrand Factor (vWF) which has two major functions: it serves by bridging between platelets and injury site in the blood vessel wall, and it circulates as a complex with factor VIII, protecting it from rapid degradation. ⋯ Until now no recommendations in the orthopaedic literature have been found regarding diagnosis and treatment of vWS patients. Based on the experience with 43 orthopaedic patients presenting vWD over the last 15 years a contemporary guideline for the successful perioperative management of vWD in orthopaedic surgery is presented. In a close collaboration between the orthopaedic surgeon and the specialized haemostaseologist every invasive procedure in patients with vWD can be undertaken without the risk of excessive bleeding.
