Fig. 2From: Radiographic evaluation of early periprosthetic acetabular bone contrast and prosthetic head acetabular coverage after uncemented and cemented total hip prosthesis in dogsVentrodorsal radiographic projections of canine coxofemoral joints after uncemented (a) and cemented (b) total hip arthroplasties illustrating the prosthetic head Norberg angle measurement. PHN angle = prosthetic head Norberg angle; IPFH axis = interprosthetic-femoral head axis; PHA axis = prosthetic head acetabular axisBack to article page
