Fifty-Six Years after Acrylic Hemiarthroplasty and after Then: A Case Report of Revision THA.
We revised an acrylic femoral hip prosthesis to a total hip prosthesis for an 86-year-old female. The implant was made of dental resin and had functioned for 56 years in situ, though its stem had broken. Because of no osteolytic reaction, the reconstruction was relatively easy. From the result of histologic and radiologic examination, the bio-inertness of material and uncemented fixation seemed to contribute the minimum bone loss and to the favorite spontaneous arthrodesis after providing good joint function in her middle age.
期刊介绍：
MEDICAL IMPLANTS are being used in every organ of the human body. Ideally, medical implants must have biomechanical properties comparable to those of autogenous tissues without any adverse effects. In each anatomic site, studies of the long-term effects of medical implants must be undertaken to determine accurately the safety and performance of the implants. Today, implant surgery has become an interdisciplinary undertaking involving a number of skilled and gifted specialists. For example, successful cochlear implants will involve audiologists, audiological physicians, speech and language therapists, otolaryngologists, nurses, neuro-otologists, teachers of the deaf, hearing therapists, cochlear implant manufacturers, and others involved with hearing-impaired and deaf individuals.
