Cellular basis for failure of joint prosthesis
Bio-Medical Materials and Engineering, 1996In recent times, loosening of joint prosthesis resulting in failure, is of grave concern to orthopedicians. It is estimated that 50% of total hip replacements become loose after 15 years, and most of them require either revision surgery or resection orthoplasty.

Prototype of glenohumeral joint for use as prosthesis
2013 Pan American Health Care Exchanges (PAHCE), 2013The aim of this paper is focused on the use of a mathematic model, similar to the glenohumeral joint system, to develop a dimensional analysis of this, in order to get mechanical parameters and, based in the results, we implement a shoulder prosthesis prototype. The mechanical model is based on a simplification of the musculoskeletal shoulder.

Total Knee Joint Replacement Prosthesis
Orthopedic Clinics of North America, 1971Summary In summary, we feel that the total replacement knee joint prosthesis deserves a permanent place in the armamentarium of the reconstructive surgeon. Instability due to combined femoral and tibial articular destruction is the indication for the procedure.

Biomechanical Modeling of Hip Joint Prosthesis
World Tribology Congress III, Volume 2, 2005In this work a Bombelli cementless isoelastic RM total hip prosthesis was considered. It was implanted over a course of 14 years on the patient and studied subsequently to its chirurgical replacement. Computed Tomography, radiographies and 3-D laser scanning were used to assess the prosthesis geometry, while the original femur anatomy was modeled based

Design considerations in a rolamite knee joint prosthesis
Journal of Biomedical Materials Research, 1973AbstractProblems encountered with existing total knee prostheses are briefly summarized. Existing prosthesis designs giving anatomically correct relative planar motion between femur and tibia are reviewed. A design incorporating a Rolamite suspension is proposed and evaluated.

Replacement of the trapeziometacarpal joint with a cemented (Caffinière) prosthesis
The Journal of Hand Surgery, 1989Between 1978 and 1985, 31 Caffinière prostheses were implanted in the first carpometacarpal joints of 28 patients for treatment of degenerative osteoarthritis (26 patients) or rheumatoid arthritis (2 patients). At follow-up an average of 48 (13 to 77) months after operation, four hands had reoperation, with the replacement of six components, five cups ...

Histiocytic Lymphadenitis Associated with a Large Joint Prosthesis
American Journal of Clinical Pathology, 1993Distinctive microscopic findings in enlarged axillary lymph nodes removed during modified radical mastectomy in a 76-year-old woman with a previous ipsilateral total shoulder joint replacement are described. The sinuses of the lymph nodes were distended by numerous large macrophages that had abundant granular eosinophilic cytoplasm.

A new Approach to the Fixation of a Metacarpophalangeal Joint Prosthesis
Engineering in Medicine, 1983A significant problem with rigid prosthetic stems applied in the finger bones, as well as in other bones of the upper and lower extremity, is resorption of bone at the interface. An investigation was carried out using a plastic plug which would more evenly distribute the stresses to the bone, with fine ridges to produce enhanced fixation by bony ...

Metacarpophalangeal Joint Arthroplasty with a Metallic Hinged Prosthesis
Clinical Orthopaedics and Related Research, 1984A long-term clinical study of 41 Flatt metallic hinged prostheses inserted in the metacarpophalangeal joints of ten rheumatoid patients was completed to provide a historic and clinical perspective of the ongoing clinical performance of this prosthesis.
