85 patients with 96 cementless pressfit hip implants were followed over a period of at least 5 years postoperatively. Average Harris score was 87.5 points. One socket had to be exchanged because of aseptic loosening. Additionally, 5 implants developed radiolucent lines, only one of them totally around the socket. In no case an exchange of the stem was necessary; one stem initially sank by 4 mm axially but was stable at the last follow-up investigation. Only one patient personally is dissatisfied with the outcome of the operation. In no case, implant specific complications such as breakage of the implant, breakage or crack of the stem, or shattering of the pelvic girdle by acetabular-screwing could be observed.

This study investigates the utilization of titanium gypsum (TG) and construction waste soil (CWS) for the development of sustainable, cement-free Controlled Low Strength Material (CLSM). TG, combined with ground granulated blast furnace slag, fly ash, and quicklime, serves as the binder, while CWS replaces natural sand. Testing thirteen mixtures revealed that a CWS replacement rate of over 40% controls bleeding below 5%, with a water-to-solid ratio between 0.

Cement-free and photosynthetic cyanobacterial cell-based living building materials (LBMs) can be manufactured using microbially induced calcium carbonate precipitation (MICP) technology. Here, we present a protocol for cultivating Leptolyngbya boryana GGD and manufacturing LBMs using a sand-gelatin solution. We describe steps for fabricating acrylic molds and mixing abiotic substances with cyanobacterial cells for constructing LBMs.

Background: The objective of this study is to organise data on complications following total hip replacement (THA) over a span of 10 years, specifically focussing on cases that necessitated revision endoprosthetic surgeries. The objective is to create a recommendation for an All-Ukrainian registry of initial and repeated hip arthroplasty (HA) and standardise the terminology used to define "revision of total hip replacement surgery".
Methods: The retrospective analysis examined 236 instances of revision hip arthroplasty (rTHA) performed at the Institute of Traumatology and Orthopaedics Centre between January 2005 and December 2021.
The Impact of Fly Ash on the Properties of Cementitious Materials Based on Slag-Steel Slag-Gypsum Solid Waste.

This paper presents a novel low-carbon binder formulated from fly ash (FA), ground granulated blast furnace slag, steel slag, and desulfurization gypsum as a quaternary solid waste-based material. It specifically examines the influence of FA content on the mechanical properties and hydration reactions of the quaternary solid waste-based binder. The mortar test results indicate that the optimal FA content is 10%, which yields a 28-day compressive strength 11.

Foam 3D printing in construction is a promising manufacturing approach that aims to reduce the amount of material, hazardous labor, and costs in producing lightweight and insulating building parts that can reduce the operational energy in buildings. Research using cement-free mineral foams derived from industrial waste showed great potential in previous studies that reduced the amount of concrete needed in composite structures. This article collates the latest developments in this line of work.
