5.5 Spinal Pedicle Screw System – Titanium Posterior Fixation Implant for Thoracolumbar Fusion

Overview of the 5.5 Spinal Pedicle Screw System

The 5.5 Spinal Pedicle Screw System represents a pinnacle in posterior spinal stabilization technology. Designed to address a wide spectrum of spinal pathologies, this system provides orthopedic surgeons and neurosurgeons with a reliable, low-profile solution for the thoracic, lumbar, and sacral spine. At OrthoPro, we understand that surgical precision relies on high-quality instrumentation, which is why our system is manufactured from medical-grade Titanium Alloy to ensure biocompatibility and biomechanical integrity.

The core of the system is the 5.5mm diameter rod, which strikes an optimal balance between fatigue strength and contouring capabilities. Whether addressing degenerative diseases, trauma, or deformities, the 5.5 Spinal Pedicle Screw System facilitates efficient assembly and rigid fixation, ultimately promoting solid bony fusion.

Engineered for Surgical Excellence

Our fixation system incorporates advanced design features that streamline the surgical workflow while maximizing patient safety. The system’s versatility makes it suitable for both open and minimally invasive procedures.

Advanced Screw Technology

The pedicle screws are available in various configurations, including Monoaxial, Polyaxial, and Reduction (Long Arm) types. The Polyaxial screws allow for up to 60 degrees of angulation, significantly simplifying rod insertion in cases with anatomical misalignment. The screw heads feature a friction-fit design that maintains the head position during rod installation, reducing surgical frustration.

Superior Thread Design

To enhance fixation strength, the screws utilize a dual-lead thread pattern. This design allows for faster insertion, reducing operative time. Furthermore, the self-tapping tip eliminates the need for separate tapping steps in most bone qualities, while the optimized thread pitch maximizes purchase in both the cortical shell and cancellous bone, providing superior pull-out resistance.

Reliable Locking Mechanism

The system utilizes a robust set screw mechanism designed to prevent cross-threading. The internal thread design creates a secure lock between the rod and the screw head, minimizing the risk of postoperative loosening or screw backout. This “locking” capability is critical for maintaining spinal alignment during the fusion process.

Clinical Indications

The 5.5 Spinal Pedicle Screw System is indicated for posterior, non-cervical pedicle fixation in skeletally mature patients. It is intended to stabilize the spine as an adjunct to fusion for the following conditions:

• Degenerative Disc Disease (DDD): Back pain of discogenic origin with degeneration confirmed by patient history and radiographic studies.
• Spondylolisthesis: Grades 3 and 4, requiring reduction and stabilization.
• Trauma: Fractures, dislocations, and instability of the thoracolumbar spine.
• Spinal Stenosis: Narrowing of the spinal canal requiring decompression and stabilization.
• Deformities: Correction of Scoliosis, Kyphosis, and Lordosis.
• Tumor: Resection and reconstruction of the spinal column.
• Pseudoarthrosis: Treatment of failed previous fusion attempts.
