Imaging findings OR Procedure details
Plain radiographs diagnosed late bone changes.
In the first stage may be soft tissue oedema.
Then we see hypertrophy of epiphyseal osteoporosis with preserving the integrity of the joint.
Later we find subchondral cysts.
In a subsequent step of cartilage destruction is already necked accompanied articular bone abnormalities.
Finally we find joint space loss and disorganization of structure with bone abnormalities and cartilage.
Ultrasound is the initial imaging method for studying joint,
abdominal and brain haemorrhage,
in patients with open fontanelle.
The U.S.
has advantages over MRI,
one of which is its ability to
differentiate synovial hypertrophy and hemosiderin deposits (Fig. 12 Fig. 13 Fig. 14 Fig. 15).
CT (Fig. 18 Fig. 19 Fig. 22 Fig. 23 Fig. 24) and MRI (Fig. 25 Fig. 26 Fig. 29 Fig. 30) complement the study with greater accuracy
MRI is a highly accurate diagnostic method that allows us to assess the involvement both intra and extra-articular and severity depending on the scale that is based supports and values all scale criteria of Denver and the European Score.
We study therefore potentially reversible lesions effusion / haemarthrosis,
synovial hypertrophy and hemosiderin,
and irreversible: changes in the subchondral bone (bone erosions and subchondral cysts) or joint margins and loss of articular cartilage.
With MRI can pinpoint the exact location of the spill,
its size,
stage blood,
if any clots and the possibility of rebleeding.
MRI can also assess the extra-articular involvement and other musculoskeletal injuries not haemophiliacs.
