The dorsocranial prominence is evident at the level of the left gluteal musculature, due to the displacement of the greater femoral trochanter.
These lesions, like pelvic lesions, are fairly common in adult cows and result from traumatic events related to mounting during estrus, slipping or falling, and dystocia.
This animal showed severe lameness immediately after the traumatic event, which improved considerably over time, allowing the animal to recover. The severity of the symptoms and the prognosis depend both on the presence of any concomitant lesions to the nerves, muscles, or bones of the femur or pelvis, and on the position of the femoral head.
Differential diagnosis: pelvic fractures, obturator nerve paralysis, spinal fractures, femoral neck fractures.
