Summary
Vertebral clefts are key for diagnosing skeletal dysplasias, particularly in infants under one year old. These spinal abnormalities appear most often in the thoracolumbar region.
Area of Science:
- Medical imaging
- Skeletal biology
- Pediatric radiology
Background:
- Skeletal dysplasias are a diverse group of genetic disorders affecting bone and cartilage development.
- Accurate diagnosis of skeletal dysplasias is crucial for appropriate management and genetic counseling.
- Vertebral anomalies, including clefts, can be important diagnostic markers.
Purpose of the Study:
- To evaluate the diagnostic significance of coronal and sagittal vertebral clefts in identifying specific skeletal dysplasias.
- To determine the prevalence and location of vertebral clefts in various skeletal dysplasia diagnoses.
Main Methods:
- A retrospective review of cases from the International Skeletal Dysplasia Registry database.
- Analysis of spinal imaging (AP and lateral views) from 143 patients across 40 diagnoses.
- Focus on major groups including atelosteogenesis, chondrodysplasia punctata, dyssegmental dysplasia, Kniest dysplasia, and short rib polydactyly syndrome.
Main Results:
- Vertebral clefts were present in 40 diagnosed skeletal dysplasias, predominantly in infants (<1 year old, 94%).
- Clefts were most common in atelosteogenesis (88%), chondrodysplasia punctata (79%), and dyssegmental dysplasia (73%).
- Coronal clefts were more frequent than sagittal clefts, primarily located in the thoracolumbar spine.
Conclusions:
- Vertebral clefts are highly valuable diagnostic indicators for specific skeletal dysplasias, especially in young children.
- The findings confirm the diagnostic utility of vertebral clefts within established groups but did not identify new entities.
- Early identification of vertebral clefts aids in the diagnosis of pediatric skeletal disorders.

01:06Body Planes
Body planes in anatomy are imaginary flat surfaces used as reference points to divide the body into sections for anatomical study. These planes are essential for understanding the orientation, relationships, and spatial organization of anatomical structures.
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...

01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

01:09Overview of the Axial Skeleton
The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs.

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
