Flexible System Facilitates Pedicle Screw Fixation

An innovative spinal fixation system provides the ability to create a rigid construct in the thoracolumbar spine, without sacrificing ease-of-use.

The Streamline minimally invasive spinal (MIS) fixation system is intended for use via a percutaneous or mini-open approach for posterior, noncervical pedicle fixation in T1-S2, using cannulated pedicle screws, set screws, and rods. The system offers a broad range of implants and instruments, with the ability to tailor treatment to a specific patient for a more efficient, streamlined, implant experience. The system includes integrated, disposable, and easily detached extension sleeves. A 60° conical screw angulation provides intraoperative flexibility, while a double lead thread design provides for faster implantation.


System specifications include standard cannulated polyaxial set screws in diameters that include 5.5 mm, 6.5 mm, and 7.5 mm, and optional screw diameters of 4.5 mm and 8.5 mm. The screw lengths range from 20–55 mm, depending on screw diameter, and all screws use a standard T25 drive mechanism. The system also includes standard 5.5 mm diameter pre-bent rods from 35–150 mm in length and optional pre-bent long rods and straight rods, resulting in robust reduction capabilities of up to 30 mm. The Streamline minimally invasive spinal (MIS) fixation system is a product of Pioneer Surgical Technology (Marquette, MI, USA).

“The Streamline MIS System provides comprehensive options for our surgeons and their patients,” said Dan Webber, CEO of Pioneer Surgical. “Pioneer has designed a system that includes both innovative implants and instrumentation for a streamlined surgical technique. The launch of this system is further proof that Pioneer Surgical is dedicated to providing a complete product offering for our distribution partners.”

Pedicle screws provide a means of gripping a spinal segment. The screws themselves do not fixate the spinal segment, but act as firm anchor points that can then be connected with a rod. The screws are placed at two or three consecutive spine segments and then a short rod is used to connect the screws; this construct prevents motion at the segments that are being fused. After the bone graft grows, the screws and rods are no longer needed for stability and may be safely removed with a subsequent back surgery. However, most surgeons do not recommend removal unless the pedicle screws cause discomfort for the patient.
