Rads fo the pelvic bones and spine – 

The patient had traumatic pelvic fractures involving the left acetabulum with surgical repair 7 years ago. A non-locking acetabulum plate was used fixed with 5 screws as well as 4 pins for a trochanteric osteotomy.

Three pins are in situ within the left femoral trochanter. One of the pins has migrated into the hypaxial muscles of the caudal spine. The pin is situated in an oblique craniodorsal-to-caudoventral position with the tip pointing craciad. There is no obvious soft tissue swelling or other reaction surrounding the pin. The rectal wall does not present any abnormalities radiographically.

Both hip joints present signs of moderate osteoarthritis. On the right side this is a consequence of mild hip dyplasia exclusively and the change are mainly restricted to the femoral head and neck. On the left side this is a composite effect of the mild hip dysplasia and the traumatic injury of the acetabulum. The osteoarthritic changes involve the acetabular groove here as well. Bone healing of the left acetabulum is complete. The implant is inert but loosening of all screw heads and mild bone atrophy under the plate is noted. The left femoral head and neck reveal demineralization consistent with disuse osteopenia. The volume of the right thigh musculature is moderately reduced indicating chronic disuse as well.
