Techniques in Cementation for Hip Hemiarthroplasty
Hip fractures in the elderly population remain a significant public health concern. With a rise in the incidence of osteoporosis, orthopaedic surgeons must be familiar with different fixation options in both trauma and arthroplasty to minimize complications and implant failure following treatment of femoral neck fractures. Cemented hip hemiarthroplasty is a reliable method for restoring functio...
متن کاملBoriding of In-738 Superalloy via the Pack Cementation Method and the Study of the Kinetic of Boride Layer Formation
In this study, mechanism and kinetic of formation of boride layer on In-738 superalloy were investigated via diffusion pack cementation method. Boriding was carried out at 900 °C for several short times (5, 15, 45 and 60 min). Phase study by means of X Ray defragtion (XRD) indicated that in addition to Ni3B, other phases such as Cr5B3, AlB2, and W2B were formed at the first period of process, a...
متن کاملIn vitro biological response to a light-cured composite when used for cementation of composite inlays.
OBJECTIVE To define the cytotoxicity of a photo-cured composite when used as a bonding system under a composite inlay. METHODS Composite specimens were photo-cured with or without a 2 mm composite inlay interposed between them and the light source. Samples were extracted in complete cell culture medium and the obtained eluates applied to primary cultures of human pulp and gingival fibroblasts...
متن کاملTibial component fixation with cement: full- versus surface-cementation techniques.
Despite excellent outcomes with cemented tibial components in total knee arthroplasty, it still is debated whether the tibial stem should be cemented and what the optimal tibial stem design should be. Proponents of full cementation of the tibial stem and component state that better short-term and long-term component fixation is achieved when full cementation is used. Advocates for surface cemen...
متن کاملChromium Deposition on Cobalt-Based Alloys by Pack-Cementation and Behaviour of the Coated Alloys in High Temperature Oxidation
Two TaC-strengthened cobalt-based alloys, with compositions Co-10Cr-0.25C-4.4Ta and Co-10Cr-0.5C-8.7Ta (wt.%) underwent Cr-deposition by pack-cementation, followed by heat-treatment to allow Cr diffusing deeper in their sub-surface. Thereafter they were tested for 50 hours at 1200°C in a thermobalance. These alloys were successfully enriched in chromium, with a maximal content on surface of abo...
