Reasons not to try relocation of hips…

Dislocated hip

On this pelvis Xray you can see two hip replacements, the left one is dislocated.  If you look closely you can also see a fracture line just superior to the prosthesis near the greater trochanter.  Be careful reducing these without obtaining orthopedics input. 

The other prosthesis is interesting.  It is a hip replacement with a constrained acetabular liner.  You can see a radioopaque ring around the femoral head component of the arthroplasty.  This is a ring that functions to hold the hip in place.  If this dislocates (not in this case), then this requires open surgical intervention for relocation.  Don’t try to put one of these back in!
