Background: Unicortical plate fixation offers several theoretical advantages in the treatment of metacarpal shaft fractures compared to bicortical fixation. This approach avoids the potential hazard of excessive drilling into the volar cortex, thus minimizing damage to surrounding soft tissues and helping prevent complications related to improperly sized screws. These benefits prompted our team to conduct a preliminary clinical study to investigate the effectiveness and safety of this approach.

Hypothesis: Proximal humerus fractures present a treatment challenge due to varied fracture configurations and a lack of consensus on optimal management. Locking plate designs offer promising solutions, yet technical guidelines for successful outcomes remain elusive. Complications are common, with fixation-related failures often attributed to varus collapse.

Objective: Accurate rotational reduction following tibial shaft fracture fixation is absent in up to 36% of cases yet may be critical for lower extremity biomechanics. The objective of this cadaveric study was to compare the results of freehand methods of reduction with software-assisted reduction.
Methods: Four fellowship-trained orthopaedic trauma surgeons attempted rotational correction in a cadaveric model with fluoroscopic assistance (without radiographic visualization of the fracture site) using (1) their method of choice (MoC) and (2) software assistance (SA).
Simulation analysis of surgical neck fractures of the humerus related to bone degeneration.

The most common type of proximal humerus fracture is surgical neck fracture. The purpose of this paper is to study the mechanical mechanism and the effect of bone degeneration on humeral surgical neck fractures. The right humerus finite element models were established based on CT computed tomography.

Osteoporosis is the most common bone metabolic unbalance, leading to fragility fractures, which are known to be associated with structural changes in the bone. Cortical bone accounts for 80 % of the skeleton mass and undergoes remodeling throughout life, leading to changes in its thickness and microstructure. Although many studies quantified the different cortical bone structures using CT techniques (3D), they are often realised on a small number of samples.
