UNLABELLED The aim of this study was to assess the pattern of annexin V uptake in hip and knee prostheses suspected of being infected. METHODS A total of 7 patients undergoing revision surgery for hip or knee prostheses were studied; 5 patients had total hip replacements, and 2 had total knee replacements. Infection was confirmed by pathology, culture results, laboratory evaluation, and clini...

The Müller type cemented hip prosthesis, also called self-locking prosthesis, is one of the most extensively copied and utilized hip prostheses. Considering the implantation of the cemented stem, the author originally suggested achieving a press fit between the stem and endostal cortex by implanting a prosthesis of the largest possible size. Analyzing our group of patients who undergo aseptic s...

components for the reconstruction of the acetabulum and metal femoral head components for conventional THA and RHA. The ACCIS®metal components are made of a chrome-cobalt-molybdenum alloy, but are different from other metal-on-metal prostheses. The surfaces of the metal components are engineered with the ceramic Titanium-Niobium-Nitride (TiNbN) in order to minimize metal particulate wear, to pr...

OBJECTIVES To determine risk factors for revision in patients implanted with a commonly used metal on metal (MoM) hip replacement. DESIGN Retrospective cohort study in combination with a prospective national retrieval study (Northern Retrieval Registry (NRR)). SETTING Combined orthopaedic unit in combination with the NRR. PARTICIPANTS All patients implanted with a DePuy Pinnacle MoM hip p...

BACKGROUND There is no universal hip implant suitably fills all femoral types, whether prostheses of porous short-stem suitable for Hip Arthroplasty is to be measured scientifically. METHODS Ten specimens of femurs scanned by CT were input onto Mimics to rebuild 3D models; their *stl format dataset were imported into Geomagic-Studio for simulative osteotomy; the generated *.igs dataset were i...

OBJECTIVE To compare 10 year revision rates for frequently used types of primary total hip replacement to inform setting of a new benchmark rate in England and Wales that will be of international relevance. DESIGN Retrospective cohort study. SETTING National Joint Registry. PARTICIPANTS 239 000 patient records. MAIN OUTCOME MEASURES Revision rates for five frequently used types of total...

PURPOSE To compare and combine dual-energy based and iterative metal artefact reduction on hip prosthesis and dental implants in CT. MATERIAL AND METHODS A total of 46 patients (women:50%,mean age:63±15years) with dental implants or hip prostheses (n = 30/20) were included and examined with a second-generation Dual Source Scanner. 120kV equivalent mixed-images were derived from reconstruction...

BACKGROUND & OBJECTIVE Hip fracture is common osteoporotic fracture associated sometimes with failed internal fixation. Joint replacement is commonly used to salvage failed internal fixation of hip fractures (FIFHF). Our objective was to present the outcome of Arthroplasty after FIFHF in our patients. METHODS A prospective analysis was made on consecutive patients who underwent prosthetic rep...

Abstract Background Accurate preoperative planning is an important step for accurate reconstruction in total hip arthroplasty (THA). Presently, completed using either a two-dimensional (2D) template or three-dimensional (3D) mimics software. With the development of artificial intelligence (AI) technology, AI HIP, software based on can quickly and automatically identify acetabular femur morpholo...
