Early Versus Delayed Cranioplasty After Decompressive Craniectomy: A Systematic Review and Meta‐Analysis

Brain and Behavior, Volume 16, Issue 3, March 2026.
Overall Complications • Early cranioplasty showed a higher (but non‐significant) risk • RR 1.43 (95% CI: 0.81–2.53) • Heterogeneity: I2 = 57% Post‐operative Infection • Early cranioplasty associated with a non‐significant increase • RR 1.36 (95% CI: 0.36–5.11) • Heterogeneity: I2 = 38% Operative Time • Early cranioplasty resulted in a significantly ...

Specific heat capacity and thermal conductivity of PEEK/Ag nanoparticles composites determined by Modulated-Temperature Differential Scanning Calorimetry [PDF]

, 2016
The thermal conductivity accurate measurement of polymer based composites is a challenge: it would allow us to understand the mechanisms of thermal transport in such materials. Silver nanoparticles were introduced in Polyetheretherketone matrix and their

Comparing the Prognostic Utility of Vertebral and Endplate Bone Quality Scores for Cage Subsidence Following Single‐Level Anterior Cervical Discectomy and Fusion: A Retrospective Analysis

Orthopaedic Surgery, Volume 18, Issue 3, Page 489-499, March 2026.
MRI‐derived bone quality metrics are reliable predictors of cage subsidence following ACDF. Their implementation may be used to guide surgical planning and improve outcomes. ABSTRACT Objective Cage subsidence following anterior cervical discectomy and fusion (ACDF) is linked with poor bone quality.

Augmenting the bioactivity of polyetheretherketone

Frontiers in Bioengineering and Biotechnology, 2016
Background Polyetheretherketone (PEEK) may be advantageous as an alternative material to metal alloys in some orthopaedic applications. However, it is bioinert and does not osseointegrate1. A novel accelerated neutral atom beam technique (ANAB) has been developed to improve the bioactivity of PEEK where the surface is modified to a depth of 5 nm ...

A covalent organic/inorganic hybrid proton exchange polymeric membrane: synthesis and characterization [PDF]

, 2005
Commercial polyetheretherketone (Victrex PEEK) was sulfonated up to 90% degree of sulfonation (DS), then reacted with SiCl4 to obtain a hybrid polymer. The product was characterized by 29-Si NMR and ATR/FTIR spectroscopies demonstrating the formation of
