Introduction:
Metaphyseal chondrodysplasia, Jansen type (JMD), is a rare form of endochondral ossification resulting in short limbs and dwarfism.
Case Report:
A child presented with JMD and was found to have involvement of the cervical spine. Conservative treatment was given to the patient who at the long-term follow-up continues to have no neurological findings or cervical spine instability.
Conclusions:
To our knowledge, this case represents the first report of involvement of the superior cervical spine in a patient with JMD. Clinicians should be aware of this potential albeit rare finding.

Sutures of the Skull
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 Disorders
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 Bones: Lateral View
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...
