Resumen

Se revisan las técnicas de artrodesis cervical anterior postdiscectomía con injerto óseo, placa cervical, caja intersomática y placa-caja, discutiendo las ventajas mecánicas que aporta cada sistema. La alternativa a la artrodesis es la discectomía simple o la artroplastia con prótesis discal. Los sistemas placa-caja integrados pueden considerase como el resultado final de la evolución de los conceptos de artrodesis cervical. Se describen detalladamente los sistemas placa-caja actualmente disponibles.

Palabras clave:
Fusión cervical
Placa cervical anterior

Summary

The surgical techniques for anterior cervical postdiscectomy arthrodesis are reviewed, including bone graft, cervical plates, intervertebral cages and plate-cage systems. The biomechanical advantages of each method are discussed. An alternative to arthrodesis are simple discectomy and arthroplastia with disc prosthesis. Integrated plate-cage systems are the final result in the evolution of the cervical arthrodesis developments. The available plate-cage systems are described.

Key words:
Cervical fusion
Anterior cervical plate
Intervertebral cage
Plate-cage systems
