Summary: This study compared the morphological characteristics of the rib cage in patients with non-deformed and scoliotic spines. The rib cage of AIS patients was significantly deformed in the dorso-ventral and medio-lateral directions. While no significant differences were observed between the healthy and AIS groups in certain morphological parameters at T1-T6 levels, greater variability was seen in parameters below the lung (T7-T12).

Summary: This study aimed to develop novel methods for quantifying human rib cortical bone material properties in compression and compared them to existing tensile data. Results showed differences in compressive material properties between loading rates and no significant correlation with age, but a correlation with sample density. Rib and thorax finite element models should consider loading rate, loading mode, and age when incorporating material properties.

Summary: Pathologies of the respiratory system can cause alterations in the biomechanical function and morphology of the rib cage. This study explored the use of biplanar x-rays to study rib cage modifications at different lung volumes and evaluated its potential in characterizing rib cage kinematic patterns in patients.

Summary: In this study, the biofidelity of a mid-sized male thorax model was evaluated and enhanced using a multi-level, hierarchical validation strategy focusing on injury characteristics and model improvement. The model was validated at component and full thorax levels, demonstrating overall good biofidelity and computational stability. The validated thorax model is expected to accurately predict thorax behavior, assess injury risk, and investigate injury mechanisms in various impact scenarios.

Summary: Geometric morphometric tools are essential for understanding variation in complex traits like shape. The geomorph package has evolved with the field, introducing a new version 4.0 and a user-friendly graphical interface gmShiny. These developments position geomorph as the primary tool for GM analyses, especially those utilizing a phylogenetic comparative approach.

Summary: This study examines the morphology of the forelimb metacarpophalangeal (MCP) joint of horses and their extinct kin using geometric morphometrics, finding significant temporal correlations at 0-1 Myr intervals and a clear division between New and Old World horse morphologies. The research suggests that horses have the capacity to rapidly change their distal limb morphology to adapt to new habitats and locomotor challenges.

Summary: This study developed a new strain-based rib fracture risk function using human rib cortical bone material test data, demonstrating a stronger age-dependent decrease in failure strain. The updated probabilistic framework with the new risk function showed lowered risk predictions for younger individuals. The new risk function can be used as a direct replacement within the 2012 probabilistic framework and reduces overestimations of rib fracture risk for certain age groups.

Summary: This study investigates the impact of a lordotic porous cage on the biomechanical performance of adjacent segments. The results indicate that changes in ROM, IDP, and FJF at the adjacent segments are primarily influenced by the lordotic angle of the cage, rather than the porosity.

Summary: This study investigates sexual dimorphism in the first ribs of recent Euro-American Homo sapiens, revealing significant differences in size and shape between males and females due to divergent allometric growth patterns. Traditional morphometrics and geometric morphometrics approaches were compared for sex classification accuracy, with traditional morphometry slightly outperforming geometric morphometrics in this specific case.

Summary: Recent developments in musculoskeletal modeling have focused on model customization. Personalization of the spine profile may affect estimates of spinal loading and stability. This study investigates the biomechanical consequences of changes in the spinal profile and finds that personalizing the spine profile has medium to large effects on trunk muscle forces and negligible to small effects on spinal loading and stability.

Summary: Exercise therapy fails in about 25.0% of cases for individuals with rotator cuff tears, and one reason for this failure may be the inability to strengthen and balance the muscle forces that keep the humeral head in the correct position. This study developed computational musculoskeletal models to compare the net muscle force before and after exercise therapy between successfully and unsuccessfully treated patients. The study found that unsuccessfully treated patients had less inferiorly oriented net muscle forces, which may increase the risk of impingement.

Summary: This study aimed to explore the intra-foot biomechanical differences among individuals with chronic ankle instability (CAI), copers, and healthy individuals during dynamic tasks. The study found that copers and CAI individuals had smaller dorsiflexion angles and copers presented a more eversion position compared to healthy participants. Copers also had greater dorsiflexion angles in the metatarsophalangeal joint and more inversion moments in the subtalar joint during certain tasks. These findings can help in designing interventions to restore ankle joint functions in CAI individuals.

Summary: This study investigates the biomechanical effects of robot-assisted body weight unloading (BWU) on gait patterns in healthy young adults. The results show that dynamic robot-assisted BWU enables reduced kinetic requirements without distorting biomechanically normal gait patterns during overground walking.
