Soft tissue: depending on the degree of exposure
VIEWS
Lateromedial and caudolateral view craneomedial oblique (30 °)
The chassis is positioned medially in the region of the stifle flow and dorsal as
possible, with caution because it is a sensitive area on the horse. The beam is
directed parallel to the ground laterally and centered on the patella. Depending
on the temperament of the horse sometimes can not be fully appreciated in this
view of the distal femur and patella. The side view oblique (caudolateral oblique
craneomedial) permte appreciate osteochondral lesions of the medial condyle
and the lateral edge of the trochlea on the distal femur.
View caudocranial
The chassis is positioned superiorly in the area of the stifle and the beam is
focused on the concave region is seen in the soft tissues of the joint.
Sometimes it is useful to perform two projections with varying degrees of
exposure in order to appreciate all structures.
View proximodistal ("skyline")
Depending on the temperament of the horse can do this by extending or flexing
view the tarsus. The chassis is held pressed against the proximal tibia and
cranially and the beam is directed vertically proximal and lateral to the lumbar
region.
We extend the foot in maximum amplitude caudally leading him, and put the
frame parallel to the ground supporting it the joint. The beam perpendicular to
the ground 70 cm. dorsal to the stifle.
DIAGNOSTIC UTILITY
• Osteochondrosis
• In the area of the lateral trochlear ridge of the femur and the patella articular
surface is where we find most often an osteochondral defect with cartilage
separation.
• Irregularities in the articular surface of the patella.
• Bone cysts subchondral
• Fisitis
• Degenerative Joint Disease (EDA) periarticular osteophyte formation,
flattening of the articular surface, subchondral bone sclerosis, radiolucent areas
in the subchondral bone tibiofemoral joint space narrowing.
• Fractures of the patella, femur, tibia and fibula
• Damage of soft tissue: collateral ligaments, menisci, cruciate ligaments,
synovial capsule
• Patellar Dislocation
