To compare the biomechanical stability of various pin configurations for pediatric supracondylar humeral fractures under varus, internal rotation, and extension conditions. After electronic retrieval, 11 biomechanical studies were included. Stiffness values of pin configurations under different loading conditions were extracted and pooled. There were no statistically significant differences between two cross pins and two divergent lateral pins on the basis of the 'Hamdi method' (P=0.249-0.737). An additional pin did not strengthen two-pin construct (P=0.124-0.367), but better stabilized fractures with medial comminution (P<0.01). Isolated lateral pins are preferable because of a better balance of a lower risk of nerve injury and comparable fixation strength. Limitations such as differences in experimental setup among recruited studies and small sample size may compromise the methodologic power of this study.

The instability of hybrid wide-bandgap (WBG) perovskite materials (with bandgap larger than 1.68 eV) still stands out as a major constraint for the commercialization of perovskite/silicon tandem photovoltaics, yet its correlation with the facet properties of WBG perovskites has not been revealed. Herein, we combine experiments and theoretical calculations to comprehensively understand the facet-dependent instability of WBG perovskites.

Background: Pediatric supracondylar humeral fractures present considerable surgical challenges due to the difficulty of achieving proper fracture alignment and stable fixation while avoiding injury to the ulnar nerve. This study assesses the biomechanical performance of a novel Kirschner wire (K-wire) fixation device (KFD), designed to enhance stability and reduce complications linked to traditional K-wire configurations.
Methods: Using finite element analysis (FEA), we evaluated four fixation strategies for treatment of pediatric supracondylar humeral simple transverse fractures: crossed pin fixation, crossed pin fixation with KFD, two lateral pin fixation, and two lateral pin fixation with KFD, under various mechanical loads.
Biomechanical Implications of Asymmetric Gardner-Wells Tong Placement During Cervical Spine Traction.

In cases of cervical facet dislocations, traction is typically delivered in the acute setting with tongs attached to the skull via two pins. Although the pins are recommended to be inserted symmetrically in a neutral loading position, erroneous asymmetric pin placement has been documented in case reports, but its biomechanical implications are unknown. The current study utilized a human surrogate to evaluate the influence of asymmetrically placed pins in the axial or frontal planes.

Article Synopsis
- The study investigates the effectiveness of a new assessment method, called the Psi method, for measuring perception thresholds in diabetic peripheral neuropathy (DPN) compared to the traditional Method of Limits (MoL).
- Results showed that the Psi method yielded similar threshold values as the MoL but was more efficient, requiring fewer stimuli (30 compared to more for MoL) and producing less uncertainty.
- The authors recommend the Psi method for its reliability and efficiency in evaluating nerve function in patients with diabetes, suggesting it may be a better option for clinical use in the future.
