Hip dysplasia is painful in young dogs because abnormal wear of
joint cartilage exposes pain fibers in underlying bone and
laxity causes
stretching of surrounding soft tissues.
This technique involves removing the femoral portion of the hip
joint (i.e., the ball) to reduce the pain produced by abnormal hip
joint contact that wears away the
joint cartilage, and the
stretching of the soft tissues around the
joint due to
laxity (Figure 5).
