Objective: To report a case of bilateral humerus varus from a late antiquity archeological context in central Italy.
Materials: The individual is a 25-40-year-old female, dated to the 4th cent. CE, from the catacomb of Santa Mustiola in Chiusi, Italy.
Methods: The bones were examined macroscopically and through CT scan imaging.
Results: Both humeri show evident alterations in shape, including elongated, flattened and distally dislocated humeral heads, shortened anatomical necks, angulated upper diaphyseal shafts, and reduced overall lengths. The scapulae appear to have been mildly affected by this condition and show some bone loss and slight retroversion of the glenoid cavity.
Conclusions: Observations are consistent with a diagnosis of humerus varus deformity likely caused by a traumatic event early in the individual's life.
Significance: Varus deformity of the proximal humerus is seldom reported in bioarcheological literature. The case presented provides insight into the etiology and effects of this condition and may serve as comparison for future studies.
Limitations: Even though the absence of other skeletal deformities renders a systemic condition improbable, the traumatic etiology of the condition cannot be confirmed with certainty.
Suggestions For Further Research: Future publications of new cases may give a broader perspective of the etiology of this condition in the past.

Objective: To explore changes of humerus torque screw tip distance on stability of proximal humeral internal locking system (PHILOS) by finite element analysis, in order to provide reference for selection of intraoperative plant size.
Methods: The proximal humerus 3D model was constructed based on Synbone artificial bone model in 3D engineering drawing software, and the corresponding 3D model was constructed based on PHILOS bone plate contour. The model was modified to simulate comminuted proximal humerus fracture, and the operation model was simulated after fracture, and the fixed operation model was assembled, the apex distance of humerus moment screw was set as 4, 8, 12 and 16 mm respectively.

Introduction: Proximal humerus fractures are prevalent, especially among the elderly, and pose significant challenges in treatment, particularly for displaced fractures. Despite the availability of various surgical techniques, outcomes remain inconsistent, often due to poor anatomical reduction and fixation. This study examines the correlation between specific radiographic parameters and functional outcomes, aiming to identify key predictors of recovery.

Introduction: Tibial plateau fractures, which constitute approximately 1% of all fractures with an incidence of 10.3/100,000 annually, result from varus or valgus forces combined with axial loading in the knee. These fractures display a bimodal distribution, affecting younger individuals through high-velocity trauma and older individuals through low-energy trauma.

Background: The newborn transphyseal fracture of the distal humerus is frequently misdiagnosed with an elbow dislocation due to the absence of the lateral condyle ossification node. No consensus has been reported either for the diagnosis or the management of these rare fractures. This study aimed to analyze a series of newborns with transphyseal distal humerus fractures.

Background: Locking plate fixation remains the mainstay of surgical fixation of unstable proximal humerus fractures, however rates of failure remain high. The aim of this study was to identify risk factors that could be used to predict the likelihood of fixation failure.
Method: Patients with proximal humerus fractures managed with locking plate fixation between 2010 and 2019 at a Level 1 trauma centre were included.
