Bone Cancer: A mid-thigh amputation

An 8 year-old female Rottweiler weighing 40.5 kg was

diagnosed with bone cancer of the right hind leg below

the stifle joint ( knee). The owner observed a slight

swelling below the knee which had increased in size

over the last 4 months causing the patient to walk with

a limp initially that progresses to frequent non-weight

bearing posture. She was frequently seen walking on

three legs. A mid-femur bone (thigh) amputation was

performed. It must be emphasized that patient selection

is important.

Fig.1 Notice the non-weight bearing posture of the right hind leg. Pain and discomfort are evident.
