A Narrative Review of the Cervical Spine Deformity Classification Systems

Area of Science:

• Orthopedics
• Neurosurgery
• Spinal Surgery

Background:

• Cervical spine deformity is a complex condition affecting the craniocervical to cervicothoracic junctions.
• It causes functional impairment and morbidity, presenting surgical challenges.
• Multiple classification systems have emerged in the last 15 years to guide treatment.

Purpose of the Study:

• To review recent cervical spine deformity classifications.
• To contextualize these classification efforts.
• To provide an overview of the current state of cervical spine deformity classification.

Main Methods:

• A PubMed search was conducted.
• Publications on cervical spine deformity classifications were identified.
• Five classification schemes were reviewed for clinical suitability.

Main Results:

• Five distinct cervical spine deformity classification systems were identified and analyzed.
• The clinical suitability of each classification was carefully considered.
• The reviewed classifications aim to improve communication and treatment guidance.

Conclusions:

• Cervical deformity classification systems are continuously evolving.
• Advancements reflect a deeper understanding of pathophysiology and etiology.
• These classifications are crucial for managing this heterogeneous group of disorders.
