Sutures of the Skull01:22

Sutures of the Skull

13.8K
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...

Bone Disorders01:29

Bone Disorders

5.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

4.5K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

General Case of Eccentric Axial Loading01:12

General Case of Eccentric Axial Loading

554
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions.
Consider a member subjected to equal and opposite forces that are applied along a line that does not coincide with the member's neutral axis. In unsymmetrical...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

7.7K
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...

Overview of the Axial Skeleton01:09

Overview of the Axial Skeleton

13.1K
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.
The axial skeleton of the...

Summary

Metaphyseal chondrodysplasia, Jansen type (JMD), a rare skeletal dysplasia, can affect the cervical spine. This case highlights the importance of monitoring for this rare complication in JMD patients.

Area of Science:

  • Orthopedics
  • Genetics
  • Pediatrics

Background:

  • Metaphyseal chondrodysplasia, Jansen type (JMD) is a rare skeletal disorder characterized by abnormal endochondral ossification.
  • JMD typically results in significant short stature and limb shortening.

Observation:

  • A pediatric patient diagnosed with JMD presented with involvement of the superior cervical spine.
  • The patient received conservative management for the spinal condition.

Findings:

  • This case is the first documented instance of superior cervical spine involvement in a patient with JMD.
  • Long-term follow-up revealed no neurological deficits or cervical spine instability in the patient.

Implications:

  • Clinicians should consider the possibility of cervical spine involvement in JMD patients.
  • Awareness of this rare manifestation is crucial for comprehensive patient care and monitoring.
