Product Introduction

The system features a pre-set locking mechanism and is designed with fixed-angle screws and variable-angle screws, allowing flexible application for different surgical options.(such as ACDF,ACCF,ACAF)

An anterior cervical plate (ACP) used to stabilise and support the spine after spinal fusion. The cervical spine refers to the vertebrae in the neck area, and fusion is the connecting of two or more vertebrae together to increase stability and relieve symptoms caused by disorders such as degenerative disc disease, herniated discs, or spinal fractures.

Anterior Cervical Plate is commonly screwed to the front (anterior) of the cervical spine. It is intended to keep the cervical vertebrae aligned and offer immediate support while the bones fuse together. The plate acts as an internal brace, preventing excessive movement and facilitating fusion.

Anterior Cervical Plate systems are typically made of titanium or titanium alloy materials. This is because titanium is a biocompatible metal that is strong, lightweight, and has good corrosion resistance. These properties make it an ideal material for medical implants that require long-term implantation in the body.

Features

Ultra-Low Profile Plate Design
With an ultra-thin 1.8 mm thickness and an ultra-narrow 12/16 mm width, the plate effectively reduces the risk of postoperative dysphagia.

Ultra-Short Plate and Highly Divergent Angle Screws
Designed to minimize interference with adjacent segments and reduce the risk of adjacent segment disease. The increased axial stress, in accordance with Wolff’s Law, promotes effective bone fusion.

Dual-Lead Thread Design
Approximately 3 mm of cortical thread at the screw tip maximizes contact with the anterior cortical bone of the vertebral body, enhancing screw purchase and fixation stability.

Advantage

● Angled screw insertion combined with tension-band mechanics enhances plate-bone-graft integration, ensuring reliable fixation and improved fusion rates.

● Prevents screw back-out and maintains construct stability throughout cervical spine movements.

● During cervical flexion, the plate provides support; during extension, it acts as a tension band — improving intrinsic stability across all movements.

● Offers immediate postoperative stability, reducing the need for prolonged external immobilization and allowing for earlier patient ambulation.

● Available in 1 to 5-level configurations, adapting to various surgical needs and anatomical requirements.

● Both fixed-angle and variable-angle screws available to accommodate different bone qualities and surgeon preferences.

● All components made from TC4 titanium alloy, offering excellent biocompatibility, strength, and corrosion resistance.

Application

● Cervical spine trauma

● Degenerative disc disease (DDD)

● Cervical spondylosis

● Cervical spinal stenosis

● Cervical disc herniation

● Cervical deformity correction

● Failed previous spinal surgery

● Spinal tumors or infections

Surgical Procedure

The anterior cervical plate fixation is integral to anterior cervical discectomy and fusion (ACDF) for cervical disc herniation or spondylosis. Under general anesthesia, the patient is placed in the supine position with neck extension. A 3-5cm transverse incision along the natural skin crease provides access to the cervical spine. Through meticulous platysma dissection and blunt retraction of the sternocleidomastoid-carotid sheath interval, the prevertebral space is exposed. After radiographic confirmation of the target level (typically C3-C7), the pathologic disc is excised with pituitary rongeurs, followed by osteophyte resection using high-speed burrs for complete neural decompression.

An interbody graft (PEEK cage/allograft filled with autologous bone) is impacted into the disc space under fluoroscopic guidance. The cervical plate is then contoured to match the vertebral anatomy and secured with self-tapping locking screws into adjacent vertebrae. Critical biomechanical functions include:

● Providing immediate stabilization (reducing segmental motion by >90%)

● Maintaining graft compression force (200-500N) to enhance fusion

● Preventing graft extrusion (occurrence <1.5% with modern plates)

The wound is closed in layers with absorbable sutures. Postoperatively, patients wear a rigid cervical collar for 4 weeks, with fusion rates exceeding 95% at 6 months when combined with low-profile plates. Physical therapy initiates at week 6 to restore cervical range of motion.
