Article Synopsis
  • Dislocation is a common complication in total hip replacement (THR), and recent increases in dislocation rates at a specific institution were linked to reduced head coverage from a new neutral liner.
  • The study aimed to compare articulating head coverage among 25 different modular neutral polyethylene liners used in THR to identify significant differences and create a new classification system.
  • Results indicated that head coverage varied significantly between the liners (from 167.7° to 194.8°), leading to the conclusion that even neutral liners differ in coverage, prompting the proposal of a "hemispheric coverage index" for better distinction.

Aims: Ibrutinib is used in the treatment of certain B-cell malignancies. Due to its CYP3A4-mediated metabolism and highly variable pharmacokinetics, it is prone to potentially harmful drug-drug interactions.

Methods: In a randomized, placebo-controlled, three-phase crossover study, we examined the effect of the CYP3A4-inhibiting antifungal posaconazole on ibrutinib pharmacokinetics.

Background And Purpose: There is concern among clinicians regarding the performance of thin, highly cross-linked polyethylene acetabular liners at high inclination angles that cause edge contact and high contact stresses. We studied ex vivo wear performance of thin, vitamin-E grafted, highly cross-linked polyethylene (Vivacit-E) liners in relation to high acetabular inclination angle.

Materials And Methods: Wear of Vivacit-E acetabular liners (thickness 4.

Dislocation is one of the most common complications after primary total hip arthroplasty (THA). Several patient-related risk factors for dislocation have been reported in the previous literature, but only few prediction models for dislocation have been made. Our aim was to build a prediction model for an early (within the first 2 years) revision for dislocation after primary THA using two different statistical methods.

This article explores the dynamic interaction of emergency policies and parliamentary constitutional review in the early policy response to the COVID-19 outbreak in Finland. A thorough analysis of the official records of Parliament's Constitutional Law Committee shows how the Government's use of delegated emergency powers raised particular concerns about inter-institutional transparency during the state of emergency. These findings prompt an enquiry into whether delegated emergency powers and the related quest for centralized transparency-led accountability produced a rupture in the theory of complex multicentric policymaking.
