Corrosion of modular hip prostheses.
Nine uncemented hip prostheses of modular design were revised because of late infection (2 cases), femoral stem loosening or fracture (2), loosening of threaded cups (3) and protrusion of bipolar cups (2). At surgery we found tissue discoloration and macroscopic corrosion in four of the nine prostheses, located at the head-neck junction. Histological examination in most cases showed extensive n...
متن کاملMedium-term Outcomes of Cemented Prostheses and Cementless Modular Prostheses in Revision Total Hip Arthroplasty
There is an increasing trend towards cementless modular femoral prostheses for revision hip replacement surgery, especially in patients with severe proximal femoral bone defects. However, for minor femoral bone defects, the benefit of cementless modular is not clear. We designed a retrospective cross-sectional study to compare outcomes of the two femoral implant designs. There were no significa...
متن کاملClinical evaluation of the Modular Electromechanical Lock Actuator (MELA) for above-elbow prostheses: a final report.
The Modular Electromechanical Lock Actuator (MELA) is the result of research and development (R&D) conducted under the direction of Dudley S. Childress, PhD, at the Northwestern University Prosthetics Research Laboratory (NUPRL), Chicago, Illinois. NUPRL, based upon experience with prostheses for persons with high-level, above-elbow amputations, developed the MELA to assist those persons with a...

متن کاملWill the Clinical Outcome of Cemented Modular Neck Total Hip Prostheses be Comparable to Conventional Devices?
INTRODUCTION: Modular neck total hip arthroplasty (THA) devices afford the surgeon increased intra-operative flexibility in terms of the degree of head version and offset, as well as allowing more controlled stem positioning. Strains on the outer cortical bone surface have been shown to be strongly dependent on the orientation of a THA. These strains can be a potential cause for mechanical fail...
