Background. The presence of periprosthetic osteoporosis influences the postoperative evolution of hip replacement
patients, delays the functional rehabilitation process and considerably decreases the quality of life of these patients.
Aims. The aim of the study is to demonstrate the role of periprosthetic bone mineral density (BMD) and to correlate its
values with skeletal (BMD) values.
Methods. The study was carried out at the Clinical Rehabilitation Hospital Cluj-Napoca in the period June-December
2009, on 58 patients aged between 30-83 years with uni- and bilateral cemented and uncemented total hip endoprostheses. For
the determination of the bone mineral density, the dual X-ray absorptiometry (DXA) method was used, with the software for
orthopedic prostheses available.
Results. Statistical data analysis demonstrated a direct correlation between periprosthetic (BMD) and skeletal bone mineral
density values, without 100% overlapping, which requires the presence of reference values for periprosthetic areas.
Conclusions. Although it follows the tendency of skeletal (BMD), periprosthetic bone mineral density requires T scores
specific for the periprosthetic Gruen zones.
