Efficacy and Safety of the Use of Interspinous Spacers in the Treatment of Lumbar Spinal Stenosis: Mapping Gap and Scoping Review

Pain Practice, Volume 26, Issue 5, June 2026.
ABSTRACT Objectives Low back pain is a common pathology in the general population. In people over 60 years of age, it is associated with degenerative changes that cause narrowing of the vertebral canal. Its treatment includes conservative measures and even surgery with decompression and fusion.

FE‐Based Biomechanical Analysis of AZ31B Sub‐Orbital Osteosynthesis Implant Manufactured by Superplastic Forming

Advanced Theory and Simulations, Volume 9, Issue 5, May 2026.
A concurrent finite‐element framework is presented for the design of a patient‐specific AZ31B sub‐orbital osteosynthesis implant manufactured by superplastic forming. The approach couples process simulation and biomechanical analysis to quantify the effects of thickness heterogeneity and grain‐growth‐induced strength degradation.

Deformation‐Induced Formation of Stray Grains in Additive Manufacturing of Single Crystals

Advanced Science, Volume 13, Issue 25, 4 May 2026.
Stray grain formation severely limits the additive manufacturing of single‐crystal alloys. By integrating in situ synchrotron techniques, ex situ characterization, and multi‐scale multi‐physics modeling, the authors reveal that stray grains originate from dislocations at the solid‐liquid interface, rather than thermal supercooling in conventional ...

Locking plates increase the strength of dynamic hip screws

Injury, 2008
Failure of a dynamic hip screw (DHS) fixation leads to decreased mobility of the patient and frequently to a decrease in general health. The most common mode of failure of a DHS is cut out of the lag screw from the femoral head. The second most common mode of failure is lift-off of the plate from the femur. The aim of this laboratory-based experimental
