This study examines spheno-occipital synchondrosis fusion in the modern American population and presents age ranges for forensic use. The sample includes 162 modern individuals aged 5-25 years. The basilar synchondrosis was scored as open, closing, or closed via direct inspection of the ectocranial site of the suture. Transition analysis was used to determine the average ages at which an individual transitions from unfused to fusing and from fusing to fused. The maximum likelihood estimates from the transition analysis indicate that females are most likely to transition from open to closing at 11.4 years and males at 16.5 years. Females transition from closing to closed at 13.7 years and males at 17.4 years. The probability distributions associated with these maximum likelihood estimates were used to derive age ranges for age estimation purposes. These results reflect sexual dimorphism in basilar synchondrosis fusion and agree approximately with average age at pubertal onset.

Purpose: This retrospective study aimed to assess ossification patterns and synchondrosis fusion timelines of the C1 and C2 vertebrae in pediatric age group, to help differentiate injuries from normal variations and serve as a guide when evaluating incompletely fused synchondrosis.
Materials And Methods: The study analyzed 432 CT examinations of children aged 0-72 months, conducted at a single institution between January 2010 and January 2018. The focus was assessment of the visibility and fusion of the three ossification centers and three synchondroses of the atlas, and six ossification centers and four synchondroses of the axis, based on age.
A bipartite medial cuneiform bone: a rare variant with symptomatic presentation and the classic "E-sign".

Background: Bipartite medial cuneiform bone (BMC) is located at the Lisfranc joint of the midfoot, and it represents a rare variant involving two separate ossification centers in the medial cuneiform bone. Although BMC is typically asymptomatic, it can become clinically relevant under conditions of trauma or chronic stress, affecting foot stability.
Case Report: The current imaging report describes a 48-year-old female presenting with chronic dorsal midfoot pain, worsened by extended standing and ambulation.

Odontoid synchondrosis fractures are rare pediatric spinal injuries that pose significant diagnostic and treatment challenges. These fractures, typically occurring in the C-2 vertebra, often result from high-energy trauma and are difficult to diagnose due to subtle radiographic findings. We present the case of a 4-year-old male who sustained a head injury while playing on a trampoline.

The plains vizcacha, Lagostomus maximus, is the only living species in the genus, being notably larger than fossil congeneric species, such as Lagostomus incisus, from the Pliocene of Argentina and Uruguay. Here, we compare the skull growth allometric pattern and sexual dimorphism of L. maximus and L.

Background: Forensic age estimation is a procedure which utilises many methods to estimate the age of both living and deceased individuals, including those who have died in natural disasters or man-made catastrophes. The pattern and closure of spheno-occipital synchondrosis (SOS) fusion, along with subchondral ossification of the mandibular condyle, can be used to estimate age.
Aim And Objectives: This study aims to estimate age using computed tomographic (CT) images of spheno-occipital synchondrosis fusion (SOS) and mandibular condylar cortication (MCC), and to correlate these findings with chronological age.
