Odontoid synchondrosis fractures are common in young children and often present with anterior displacement. Conservative treatment leads to high fusion rates, making it the recommended approach for most pediatric cases.
Area of Science:
- Pediatric Orthopedics
- Spinal Trauma
- Pediatric Neurosurgery
Background:
- Odontoid synchondrosis fractures are rare in general spinal trauma but common in young children.
- These fractures require careful diagnosis and management due to potential neurological deficits.
Purpose of the Study:
- To evaluate demographic data, neurological deficits, treatment strategies, and outcomes of odontoid synchondrosis fractures in children.
- To combine institutional data with published literature for a comprehensive analysis.
Main Methods:
- Retrospective chart review of four cases and inclusion of 51 cases from six published series, totaling 55 pediatric patients.
- Data collected included age, sex, diagnosis delay, fracture displacement, neurological deficits, treatment, and fusion status.
Main Results:
- The mean age was 2.8 years (9 months to 7 years); 94% of fractures showed anterior displacement.
- Spinal cord injury (SCI) occurred in 15 patients (27%), with 11 complete injuries.
- External immobilization achieved fusion in 93% (42/45) of patients; surgery was reserved for specific cases.
Conclusions:
- Odontoid synchondrosis fractures are challenging to diagnose in children under 7 with neck pain or neurological deficits.
- Conservative therapy demonstrates a high fusion rate and is recommended for most cases.
- Surgical intervention may be necessary for select individual cases.

Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary or...
Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
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...

Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
