Functional outcome following direct repair or intervertebral fusion for adolescent spondylolysis : a systematic review [PDF]

, 2012
A systematic review of the literature was performed to establish whether direct repair of the pars defect or intervertebral fusion achieves better Oswestry Disability Index scores in adolescent spondylolysis or low-grade spondylolisthesis.

Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.

Primary stability of cementless threaded acetabular cups at first implantation and in the case of revision regarding micromotions as indicators [PDF]

, 2012
The primary stability of cementless total hip endoprosthesis is of vital importance for proximate, long-term osteointegration. The extent of micromotions between implant and acetabulum is an indicator of primary stability.

A Pseudo‐Mytilus Edulis Foot Protein‐Based Hydrogel Adhesive with Osteo‐Vascular‐Immune Coupling Effects for Osteoporotic Bone‐Implant Integration

Advanced Materials, EarlyView.
Inspired by mussel proteins, YDC‐Gel‐Zn is a smart bone glue designed for osteoporotic implants. It adheres strongly to both metal implants and bone for initial fixation. In osteoporosis's inflammatory environment, it sequentially releases zinc ions and therapeutic peptides: the zinc modulates immune cells to reduce inflammation, while the peptides ...

Dynamic Torque Limitation vs Static Torque Limitation for Bone Screws in Pig Bone

Current Directions in Biomedical Engineering
Correctly torquing bone screws is important to achieve good patient outcomes. An automated system has been previously proposed that may allow more objective torquing of bone screws. Here the system is tested vs. a static torque limit in pig bone.

3D Printing of Highly Porous Polypropylene Separators for Lithium‐Ion Batteries Using Fused Deposition Modeling and Thermally Induced Phase Separation

Advanced Materials Technologies, EarlyView.
This study demonstrates the 3D printing of custom‐shaped battery separators using a polypropylene/paraffin wax composite filament. A post‐processing step creates porous structures by removing wax. The printed porous separators show promising mechanical and electrochemical performance, offering a pathway toward conformable battery designs.
