We have compared prospectively the incidence of loosening of 20 femoral stems with a matt surface with that of 20 polished stems of an otherwise identical tapered, non-modular design of Exeter hip replacement. The stems were inserted using the same technique at operation and radiographs showed no difference in the adequacy of the cement mantle or of fixation. All the patients were reviewed regularly and none was lost to follow-up. After a minimum follow-up of nine years, four matt but no polished stems had been revised for aseptic loosening. Polished stems subsided slightly within the cement mantle early, but did not loosen.

Aims: The Exeter femoral stem has a cemented, polished taper-slip design, and an excellent track record. The current range includes short-length options for various offsets, but less is known about the performance of these stems. The aim of this study was to compare the survival of short-length stems with standard-length Exeter stems.

Background: Periprosthetic femoral fractures (PFF) are a challenging complication of hip arthroplasty surgery, posing a high risk of morbidity, mortality and reoperation. The Vancouver Classification describes a B2 PFF around a loose stem with sufficient bone stock. In recent years, the number of B2 PFFs and cementation of femoral stems have increased substantially.

Background: Transverse or short oblique periprosthetic femoral fractures around total hip arthroplasty (THA) stems are typically classified as B1 fractures (stem well-fixed) and usually managed with fixation. These fractures have high non-union rates. This study aimed to identify reoperation rates in patients with operatively managed transverse or short oblique fractures around a cemented polished taper-slip stem and determine any associations with treatment failure.

Bacterial adhesion, colonization, and spread on aluminum alloy surfaces pose significant risks to human health and public safety. To address these issues, this investigation employed an ultrasonic-assisted electrodeposition method to synthesize long-lasting antibacterial Cu-TiO nanocomposite coatings on porous anodized aluminum oxide (AAO) substrates. Leveraging the cavitation effect of ultrasound, this approach fostered the dispersive incorporation of TiO nanoparticles into the resulting composite coating, thereby expediting the crystallization process of electrodeposition and refining the granular structure.

The indication for femoral stem cementation should be made on a patient-specific basis, taking physical activity, femoral geometry, and bone tissue quality into account. Age alone should not be the sole justification for cementation. The Dorr classification can serve as decision support for whether a cemented fixation should be used.
