604 32 Overview of the Musculoskeletal System

Figure 32.39 Classic features of degenerative joint disease
include sclerosis of the subchondral bone (#), osteophyte
formation (α), enthesophytes (π), articular mineralization (Ω), and
joint incongruity(*). All of these features are present in this
patient with severe osteoarthrosis of the coxofemoral joints. Figure 32.41 Lateral (a) and dorsoplantar (b) radiographs of
the tarsus with traumatic luxation of the talocrural joint. This
was repaired via surgical arthrodesis.

Figure 32.40 Lateral (a) and craniocaudal (b) radiographs of both stifles in an 11-year-old domestic shorthair that presented with
acute-onset nonambulatory hindlimb lameness. There is bilateral stifle derangement consistent with complete disruption of the
ligamentous support structures resulting in luxation. Multiple osseous avulsion fragments are present in both stifles. Surgical
stabilization was performed with an extracapsular technique.
