The Distal Tibia Nail (DTN; Mizuho, Japan) has demonstrated higher biomechanical stiffness to locking plates in previous research for A3 distal tibia fractures. It is here investigated as a fixation option for supramalleolar corrective osteotomies (SMOT). Sixteen Sawbones tibiae were implanted with either a DTN (n = 8) or Medial Distal Tibia Plate (MDTP; n = 8) and a SMOT simulated.

At the lower limb level, the deep fascia that is overlying muscles of the outer thigh and sheathing them (fascia lata) is involved in various pathologies. However, the understanding and quantification of the mechanisms involved in these sheathing effects are still unclear.

- Advanced finite element models of the thorax are crucial for studying impacts, like car crashes, but lack specific rib material properties for accuracy.
- Current non-destructive techniques, such as quantitative computed tomography, face limitations due to radiation, prompting the investigation of ultrasonic measurements for rib properties.
- This study found significant correlations between ultrasonic measurements and the mechanical properties of ribs, suggesting a promising non-destructive method for evaluating rib health in future in vivo studies.
Article Synopsis
- The study investigates how the human trunk responds to force during respiratory physiotherapy in both children and adults, highlighting differences in shape due to methodology and participant demographics.
- It involved eight children aged 5-15 months and eight healthy adults, measuring the applied force by a physiotherapist and the resulting trunk displacement, revealing time lags that affect force-displacement curves.
- The findings show maximum trunk displacements of 18 mm (children) and 44 mm (adults) with corresponding loads of 208 N and 250 N, emphasizing the need for further data on muscle activity and breathing for better trunk modeling.
Article Synopsis
- Sagittal split ramus osteotomy (SSRO) is a technique in jaw surgery where bicortical titanium screws are used in a triangular shape to stabilize a 5mm advancement of the mandible.* -
- The stability of this screw configuration was tested using six human mandibles, where a force of 129.6 N was applied, significantly exceeding typical chewing forces of 21 N.* -
- The experiment established a linear relationship between force and displacement, demonstrating that the triangular screw arrangement is stable for SSRO, providing a basis for future comparisons of different stabilization methods.*
Two series of nine frontal sled tests were conducted to evaluate the behavior of the Hybrid III and Thor-alpha dummies. The first series was conducted at 50 kph with airbag and 4 kN force-limited shoulder belt and the second series at 30 kph and only a 4 kN force-limited shoulder belt. In each series, three replicate tests were conducted with each dummy and compared with three PMHS.

The application fields for such an improved model are injury risk prediction as well as surgical planning. The geometrical reconstruction was performed using computed tomography scans and a total of 4680 shell elements were meshed on the median surface of the head skeleton with the particular characteristic of adapted mesh density and real element thickness.
