Anterior Cervical Corpectomy and Fusion (ACCF): Comprehensive Surgical Insight and Global Application

Views: 0 Author: Site Editor Publish Time: 2025-10-28 Origin: Site

ACCF is an advanced anterior cervical approach for complex cervical spine disease, restoring stability and neurological function through vertebral body resection, decompression, and fusion.

ACCF vs. ACDF: Indications and Scope

Both ACDF and ACCF use the anterior cervical approach but address different pathologies:

ACDF

Best for soft disc herniation and single-level compression. The diseased disc is removed and a fusion device is implanted, enabling smaller trauma and faster recovery.

ACCF

Preferred for multi-level vertebral fractures, OPLL, and large posterior osteophytes. ACCF provides wider decompression and stronger anterior reconstruction.

ACCF Surgical Technique

To overcome potential residual posterior compression after ACDF, ACCF removes most of the diseased vertebral body while preserving lateral borders and excises the adjacent superior and inferior discs. An appropriately sized titanium mesh cage filled with bone graft is implanted and stabilized with an anterior cervical plate-screw system to achieve solid fusion.

Advantages of ACCF

Broader decompression for OPLL and large posterior osteophytes.
Stronger reconstruction with mesh cage + plate-screw fixation for anterior column support.
Effective in multi-level disease with thorough decompression and deformity correction.

Risks and Control

Because ACCF involves a wider surgical field, stability requirements are higher. Reported titanium mesh cage (TMC) subsidence rates range from 10%–40% across cohorts.

Cage angle

smaller (ideally 0°) inclination maximizes endplate contact and reduces stress concentration.

Contact area

larger footprint distributes load and lowers the likelihood of subsidence.

Adoption across Latin America, Southeast Asia, Europe, and the Middle East shows improved decompression accuracy, shorter operative time, and favorable recovery profiles, supported by regional training and service.

FAQ

Q1. What is the main difference between ACCF and ACDF?

ACDF targets single-level, soft-tissue compression; ACCF addresses multi-level, bony or ossified compression (e.g., OPLL, large osteophytes) with wider decompression and stronger reconstruction.

Q2. What are the technical highlights of CZMEDITECH's ACCF solution?

The ARIES-III ultra-thin plate plus PISCES titanium mesh cage enables precise decompression, robust stability, and lower dysphagia and subsidence risk.

Q3. How can titanium mesh subsidence be minimized?

Use the smallest feasible cage angle (closer to 0°), maximize endplate contact area (end-cap support), and ensure proper cage sizing and alignment to distribute load evenly.

Q4. Are the implants internationally certified?

Yes. CZMEDITECH cervical fusion systems comply with CE and ISO 13485 quality standards.

Q5. Are the systems compatible with common international standards?

Design references align with major global brands (e.g., Medtronic, DePuy Synthes, Acumed) to support broad surgical scenarios and instrument workflows.

Q6. Do you provide clinical support and training?

Yes. Global partners receive surgical training, technical guidance, and after-sales support to enhance adoption and outcomes.

Q7. What is the advantage of PISCES in multi-level fusions?

The serrated anti-slip design with compatible end-caps maintains height and alignment over multiple levels, facilitating bone ingrowth and shortening fusion time.
