Cervical Lateral Mass and Pedicle Fracture Reduced with a Herbert Screw: A Technical Note.

BACKGROUND

Traumatic fractures of the cervical spine pose significant challenges in management, particularly in young patients, where preserving mobility is crucial.

PATIENT CHARACTERISTICS

A 30-year-old woman presented with a C3 lateral mass and pedicle fracture following a motor vehicle collision. Initial conservative management with a rigid cervical collar for three months failed to reduce the diastasis, and the debilitating neck pain worsened. Preoperative imaging confirmed fracture instability without spinal cord compression.

INTERVENTION AND OUTCOME

Preoperative screw trajectory planning was conducted with the My Spine MC system (Medacta), and fine-tuning was achieved on a 3D-printed model of the vertebra. A posterior midline approach was employed to expose the C3 vertebra, and a Herbert screw was inserted under fluoroscopic guidance. Imaging at three months demonstrated significant fracture reduction and early bone fusion. The patient achieved substantial improvement in functional mobility without complications.

CONCLUSION

Herbert screw fixation holds potential as a less-invasive alternative to conventional posterior stabilization for selected cervical fractures. This technical note provides the reader with the required information to support surgical planning and execution.
