Significant deterioration in quality of life and increased frailty in patients waiting more than six months for total hip or knee arthroplasty : a cross-sectional multicentre study.

Aims: The primary aim of this study was to assess whether patients waiting six months or more for a total hip (THA) or knee (KA) arthroplasty had a deterioration in their health-related quality of life (HRQoL). Secondary aims were to assess changes in frailty and the number of patients living in a state considered to be worse than death (WTD), and factors associated with changes in HRQoL and frailty.

Methods: This cross-sectional study included 326 patients, 150 males (46.

IMPACT-Scot report on COVID-19 and hip fractures.

Aims: The primary aim was to assess the independent influence of coronavirus disease (COVID-19) on 30-day mortality for patients with a hip fracture. The secondary aims were to determine whether: 1) there were clinical predictors of COVID-19 status; and 2) whether social lockdown influenced the incidence and epidemiology of hip fractures.

Methods: A national multicentre retrospective study was conducted of all patients presenting to six trauma centres or units with a hip fracture over a 46-day period (23 days pre- and 23 days post-lockdown).

Radiographic Correction Following Reconstruction of Adult Acquired Flat Foot Deformity Using the Cotton Medial Cuneiform Osteotomy.

Background: The Cotton osteotomy has been used to correct residual forefoot supination in flexible flatfoot deformity reconstruction. The purpose of this study was to delineate the radiographic effects of the Cotton osteotomy by controlling for concomitant procedures used for deformity correction.

Methods: We retrospectively analyzed 67 patients who underwent a Cotton osteotomy as part of a flatfoot reconstructive procedure.

Is the Stryker Revolution mixing system fit for purpose? Reliability and a micro-CT assessment of cement porosity.

The Stryker Revolution(TM) is a new mixing system that employs a high vacuum and a motorised mixing spatula in an effort to reduce cement porosity. We have compared Revolution(TM) with Depuy Cemvac(®), in terms of system reliability and cement porosity. Standardised Simplex P(®) and SmartSet(®) HV cement samples were produced using both mixing systems and analysed using a micro-CT scanner.

Inter- and intra-batch variability in the handling characteristics and viscosity of commonly used antibiotic-loaded bone cements.

Background: Several factors can affect the viscosity of a cement and therefore its handling characteristics. We performed an in vitro study to ascertain whether anecdotal observations of differences in handling between batches of the same brand of cement actually existed.

Methods: 3 batches of Simplex P Tobramycin (SPT), Refobacin Bone Cement (RBC), SmartSet GHV (SSG) and Palacos R+G (PRG) were tested.

In vitro comparison of Refobacin-Palacos R with Refobacin Bone Cement and Palacos R + G.

Background: Refobacin Palacos R (RPR) is no longer produced and Palacos R + G (PRG) and Refobacin Bone Cement R (RBC) have been introduced to supersede it. We performed an in vitro study to ascertain whether the handling and mechanical properties of the more recent cement preparations are different to those of their predecessor.

Methods: The 3 cements were tested to ISO 5833 and German DIN 53435 standards.
