title: Human postmortem retrieval of total hip arthroplasty.
abstract: Postmortem retrieval of well-functioning prostheses from total hip arthroplasty is essential in determining the quality and success of the implant, implant fixation, and operative technique. This report describes the retrieval procedure, including details on informed consent, retrieval procedure, and types and benefits of specimen analysis. Bone densitometry, roentgenography, and microscopy studies permit a level of assessment of operative and prosthetic performance not obtainable from clinical and in vivo roentgenographic evaluation alone. Findings from these techniques yielding data on stress shielding, bone mineral density, extent of bone-prosthesis apposition and osseointegration, and histologic activity are ultimately of considerable clinical significance. The implementation of retrieval programs, along with establishing early family and patient cooperation and proper planning practices, will continue to contribute invaluably to advances in orthopaedic science.
