The Ankle and Haemophilia: Background, Imaging and Treatment Options
Symposium Chair: Olav Versloot
Background & Relevance: Haemophilia is an X-related, inheritable blood coagulation disorder. Persons with haemophilia (PWH) suffer from low levels of factor VIII (FVIII, haemophilia A) or factor IX (FIX, haemophilia B) coagulation proteins(1). In PWH, repetitive joint trauma and associated bleeds can lead to chronic synovitis and haemophilic arthropathy, which in turn can lead to severe cartilage damage(2), decreased joint function and disability(3). The elbow, knee and particularly the ankle are most frequently affected in PWH(4). The use of prophylaxis in haemophilia has contributed greatly to sport participation of PWH and consequently attributed to the risk of sport related injuries, e.g. in the ankle region. As in recent years, the body of knowledge concerning the pathophysiology, imaging and therapeutic interventions (both conservative and surgical) of ankle involvement in PWH has greatly improved this will be the topic of this symposium. During this symposium, the pathophysiology, imaging possibilities and treatment options, both conservative as well as surgical, of the ankle in PWH will be discussed.
