Pediatric occipital condyle morphometric analysis using computed tomography with evaluation for occipital condyle...

Area of Science:

• Neurosurgery
• Pediatric Orthopedics
• Anatomy

Background:

• Occipitocervical fusions in children are complex due to smaller anatomy.
• Occipital condyle screws offer a potential solution for these challenging cases.
• Limited data exists on pediatric occipital condyle dimensions for screw placement.

Purpose of the Study:

• To evaluate pediatric occipital condyle morphometry.
• To determine if an age cutoff exists for contraindicating occipital condyle screw placement.
• To assess the feasibility of occipital condyle screw fixation in pediatric patients.

Main Methods:

• Retrospective morphometric analysis of 518 pediatric patients (1 week-9 years).
• CT imaging used to measure occipital condyle dimensions.
• Statistical analysis including t-tests to compare measurements across age and sex groups.

Main Results:

• Male patients had larger occipital condyles than females, but not clinically significant.
• Older children generally had larger occipital condyles.
• 20.65% of patients had measurements precluding occipital condyle screw placement, across all age groups.

Conclusions:

• Occipital condyle screw fixation is feasible in pediatric patients under 10 years.
• Preoperative evaluation of occipital condyle dimensions is essential for all pediatric patients.
• Individual anatomical assessment is critical for determining suitability for occipital condyle screw placement.
