Quadriceps muscle contracture, dog

Quadriceps muscle contracture, dog

Contracture of the quadriceps muscle in a dog. This dog had a previous chronic femoral fracture that healed with contracture and fibrosis of the quadriceps muscles. Note the straight alignment of the right hindlimb. This dog was unable to flex its stifle and coxofemoral joint because of fibrous adhesions in the muscle.
