Quadriceps contracture in a cat.

Quadriceps contracture associated with a healed malunion fracture of the left femur was diagnosed in a 1-year-old cat. The proximal portion of the distal fracture piece protruded through the skin of the thigh. The protruding bone was removed surgically and the area of ulcerated skin was debrided. Because the fracture was stable and the cat was able to bear weight on the affected limb, surgical correction of the malunion was not performed. Quadriceps contracture is uncommon in the cat.
