A systematic review of short- compared with standard-length Exeter stems in primary total hip arthroplasty.
Bone Joint J
January 2025
Grampian Orthopaedics, Aberdeen Royal Infirmary, Aberdeen, UK.
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.

Surface plasmon resonance (SPR) optical fiber sensors are appealing for biomolecular detection due to their inherent characteristics such as flexibility, real-time performance, and high sensitivity. Concurrently, incorporating SPR sensors into wearable devices has emerged as a significant strategy. However, the majority of traditional SPR optical fiber sensors utilize spectrometers for optical readout, which leads to a relatively bulky overall size of the sensing system.

Arthroplast Today
December 2024
Royal Infirmary of Edinburgh, Edinburgh, Scotland.
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.

A thorough procedure was developed to efficiently manufacture dogbone samples using focused ion beam (FIB) milling for micro-tensile testing. A Bruker PI 89 PicoIndenter, Billerica, MA, USA, was used as a case study, although the analysis and results are applicable to other micro-mechanical testing systems capable of mounting a standard, Ø12.7 mm × Ø3.
