Q

Pelvis Fx

A
  • Pelvis fxs usually occur in more than 1 area
    o Fxs can also cause pelvic hematoma and urethral and bladder injuries
  • Ex) widening of pubic symphysis can also lead to secondary fx and sudden widening of R SI

o Narrow transition zone between bone and lesion
o Thing + well defined sclerotic white margins

22
Q

Malignant Lesions

A

o Lytic lesion w.o sclerotic margins is considered malignant until proven otherwise
o Breast and lung cancer produce lytic lesions
o Chondrosarcomas
 Destructive in nature
