Tomographic correlation for Magerl's technique in C1-C2 arthrodesis in children

Area of Science:

• Orthopedic surgery
• Pediatric spine anatomy
• Surgical techniques

Background:

• Cervical spine injuries in pediatric patients require specialized surgical considerations.
• Magerl's technique is a common approach for C1-C2 stabilization in adults.
• Limited data exists on the applicability of Magerl's technique in pediatric populations.

Purpose of the Study:

• To assess C1-C2 vertebral morphology and dimensions in pediatric patients using tomographic imaging.
• To evaluate the feasibility of applying Magerl's technique in this age group.
• To provide anatomical data supporting the safe use of Magerl's technique in children.

Main Methods:

• Retrospective analysis of 40 normal cervical tomographies from patients aged 24-120 months.
• Statistical analysis of key measurements: C2 pedicle to C1 lateral mass length, C2 pedicle thickness, C2 isthmus screw angle, and C1 anterior arch to odontoid distance.
• Measurements were analyzed for mean values and variations.

Main Results:

• Mean length from C2 pedicle to C1 lateral mass: 30.86 mm (right), 31.47 mm (left).
• Mean C2 pedicle thickness: 5.28 mm (right), 5.26 mm (left).
• Mean screw attack angle at C2 isthmus: 46.25° (right), 44.50° (left).
• Mean distance from odontoid to C1 anterior arch: 2.17 mm.

Conclusions:

• Tomographic analysis suggests Magerl's technique is a viable surgical option for pediatric patients.
• The study provides crucial anatomical data for safe application of Magerl's technique in children.
• Further research may validate these findings in clinical practice.
