5.5 Minimally Invasive Pedicle Screw System – Titanium Percutaneous Spinal Fixation for MIS Surgery

Overview of the 5.5 Minimally Invasive Pedicle Screw System

The 5.5 Minimally Invasive Pedicle Screw System represents the forefront of modern spinal technology, designed to meet the growing global demand for Minimally Invasive Spine Surgery (MISS). At OrthoPro, we provide this advanced percutaneous fixation solution to help surgeons achieve rigid spinal stabilization while minimizing the physiological impact on the patient. Unlike traditional open surgeries that require extensive muscle stripping, our MIS pedicle screw system allows for a paraspinal approach, preserving anatomy and accelerating recovery times.

This comprehensive system is built around a 5.5mm rod platform and features cannulated polyaxial screws with extended break-off tabs. These features work in unison to simplify the complex workflow of inserting rods through small incisions, making it an ideal choice for treating degenerative disc disease, trauma, and spinal deformities in a less invasive manner.

Key Features and Engineering Advantages

The design of our 5.5 Minimally Invasive Pedicle Screw focuses on intraoperative efficiency and biomechanical security. The system includes several distinct advantages:

1. Integrated Extended Tabs (Long Arm Design)

The most defining feature of this system is the integrated extended tabs on the screw head. These “long arms” serve as a built-in retractor and a guide for rod delivery. They eliminate the need for bulky external tube retractors, providing a direct channel for the rod to be slipped into the screw head. Once the set screw is locked, the tabs are easily removed (snapped off) to leave a low-profile implant.

2. Cannulated Screw Design

Each screw is cannulated (hollow) to accommodate guide wires. This allows for safe, precise percutaneous insertion using fluoroscopic guidance. The capability to place screws over a K-wire ensures accurate trajectory and depth, which is critical in closed-approach surgeries.

3. Polyaxial Flexibility

The polyaxial head offers a generous range of motion, allowing the screw housing to angulate independent of the screw shaft. This is essential in MIS procedures where anatomical visibility is limited, as it facilitates easier rod capture even when screws are not perfectly aligned.

4. Secure Locking Mechanism

The system utilizes a reverse-thread set screw mechanism that minimizes cross-threading and head splaying. This ensures a rigid construct that resists loosening over time, promoting a solid fusion environment.

Clinical Indications

The 5.5 Minimally Invasive Pedicle Screw System is indicated for posterior, non-cervical pedicle fixation (T1-S1). It is designed to provide immobilization and stabilization as an adjunct to fusion for the following conditions:

• Degenerative Disc Disease (DDD): Confirmed by patient history and radiographic studies.
• Spondylolisthesis: Minimally invasive reduction and fixation.
• Spinal Trauma: Fractures and dislocations where open surgery poses too high a risk.
• Spinal Stenosis: Requiring stabilization after decompression.
• Spinal Deformities: Correction of scoliosis or kyphosis using MIS techniques.
• Tumor: Palliative stabilization or reconstruction.

Technical Specifications

Our implants are manufactured from premium medical-grade Titanium Alloy (Ti6Al4V ELI), ensuring excellent biocompatibility and MRI compatibility. The system is designed to be user-friendly with a streamlined instrument set.

Benefits of Minimally Invasive Surgery (MIS)

Adopting the OrthoPro 5.5 MIS System offers significant benefits for both the hospital and the patient:

• Reduced Blood Loss: Smaller incisions result in significantly less intraoperative bleeding.
• Lower Infection Risk: Minimized exposure of internal tissues reduces the likelihood of postoperative infections.
• Faster Recovery: Muscle preservation leads to reduced hospital stays and quicker return to daily activities.
• Cosmetic Outcome: Small, percutaneous incisions leave minimal scarring compared to open surgery.
