Changes in bone mineral density of the distal femur after revision total knee arthroplasty with metaphyseal press-fit stem
Periprosthetic DXA after total hip arthroplasty with short vs. ultra-short custom-made femoral stems
Background and purpose Dual-energy X-ray absorptiometry (DXA) analysis of the 7 periprosthetic Gruen zones is the most commonly used protocol to evaluate bone remodeling after the implantation of conventional femoral stems. We assessed the value of DXA after cementless primary total hip arthroplasty (THA) by comparing the effect of progressive shortening of the stem of two femoral implants on periprosthetic bone remodeling using a specifically developed protocol of analysis with 5 periprosthetic regions of interest (ROIs)
