The management of a person with haemophilia who has a fixed flexed hip and intractable pain.

The clinical picture of a fixed flexed hip associated with pain in a person with haemophilia is suggestive of a haemorrhage in that area. Sonography facilitates differentiation between a haemarthrosis, intraperitoneal haemorrhage, subperiosteal bleed, a bleed into the soft tissue around the hip joint or a psoas haematoma. All these aforementioned causes may result in the same clinical presentation. Two cases are described in which coxhaemarthrosis resulted in a flexion contracture of the joint associated with severe intractable pain. Narcotic drugs failed to alleviate the severe pain. Joint aspiration produced dramatic pain relief and early joint rehabilitation.
