The hooks and rods are also intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the cervical/upper thoracic (C1-T3) spine. The use of screws is limited to placement in T1-T3 for treating thoracic conditions only. Screws are not intended to be placed in the cervical spine. ## Device Story Marauder™ Cervical-Thoracic Spinal Fixation System is a temporary posterior spinal stabilization construct. Components include polyaxial bone screws (3.5-4.0mm diameter), hooks, and titanium rods. System utilizes linear force (not torque) for locking; external locking sleeve compresses spherical seat against screw head to lock angularity; tapered locking cap secures rod into saddle. Used by surgeons in clinical settings to stabilize spine during fusion procedures. Provides rigid structure to assist healing; removed after fusion. Benefits include stabilization of spinal segments following trauma or degenerative conditions. ## Clinical Evidence Bench testing only. No clinical data provided. Mechanical validation performed per ASTM F1798-08 (static flexion-extension, rod gripping, A-P pullout) and ASTM F1717-12 (static compression, torsional, and dynamic compression bending). Results confirmed system performance is typical of competitive spinal fixation systems. ## Technological Characteristics Materials: Ti-6Al-4V alloy (ASTM F136). Components: Polyaxial screws, hooks, titanium rods. Locking mechanism: Linear force-based; external locking sleeve and tapered locking cap. Connectivity: None. Sterilization: Not specified. Software: None. ## Regulatory Identification A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome. ## Predicate Devices - Aesculap: S4® Spinal Fixation System ([K050979](/device/K050979.md)) - K2M, Inc.: MESA® Mini Spinal Fixation System ([K081107](/device/K081107.md)) - Synthes, Inc.: Synapse System ([K070573](/device/K070573.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Pedicle Screw Spinal System 888.3050, Spinal Interlaminal Fixation Orthosis Device Class: MNI, KWP Device Product Code: II Predicate Devices: Aesculap: S4@ Spinal Fixation System (K050979) K2M, Inc .: MESA® Mini Spinal Fixation System (K081107) Synthes, Inc .: Synapse System (K070573) {1}------------------------------------------------ #### Intended Use / Indications for Use #### Intended Use: The Marauder™ Cervical-Thoracic Spinal Fixation System implants are intended to be used as a temporary construct that assists in normal healing and are not intended to replace normal body structures. The system is intended to stabilize the spinal operative site during posterior fusion procedures, attaching to the spine by means of hooks and screws joined with spinal rods and should be removed after fusion. #### Indications for Use: The Marauder™ Cervical-Thoracic Spinal Fixation System is intended to promote fusion of the cervical and thoracic spine (C1-T3) for the following conditions: degenerative disc disease (neck pain of discogenic origin with degeneration of the disc as confirmed by patient history and radiographic studies); spondylolisthesis; spinal stenosis; trauma (fracture/dislocation); failed previous fusion; and/or tumors. The hooks and rods are also intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the cervical/upper thoracic (CI-T3) spine. The use of screws is limited to placement in TI-T3 vertebrae for treating thoracic conditions only. Screws.are not intended to be placed in the cervical spine. #### Device Description The Marauder™ Cervical-Thoracic Spinal Fixation System consists of a polyaxial bone screw with a spherical-shape head, and a standard thread for interfacing bone. Screws are available in 3.5 mm and 4.0 mm diameters and lengths from 10mm to 30mm. In addition to polyaxial screws, hooks are provided for use in the cervical and thoracic spine. Three hook geometry variations are offered with the Marauder™ Cervical-Thoracic Spinal Fixation System. The hooks use the same rod locking means as the polyaxial screw implants. Titanium rods are provided in various lengths and are used to connect pedicle screws and create a rigid structure. The rods are connected to the implants by interference with the rod saddle and held into position by the locking caps. All implant components of the Marauder™ Cervical-Thoracic Spinal Fixation System are manufactured from Ti-6Al-4V alloy, conforming to ASTM F136. #### Technological Characteristics The polyaxial and rod locking mechanisms of the polyaxial screw are locked using linear force as opposed to torque. The spherical head of the screw is designed to fit within a locking spherical seat housed in the lower portion of the body. The locking mechanism utilizes an external locking sleeve that when pressed into position over the spherical seat, {2}------------------------------------------------ compresses the spherical seat against the spherical head of the screw. locking the screw angularity of the assembly. The rod locking mechanism includes a rod saddle that is integrated in the upper portion of the body. Pressing the locking cap onto the body in turn presses the rod into the rod saddle. The cap has a tapered internal borc. When the cap is in the locked position, the tapered internal bore engages an external taper on the body, securing the cap and rod to the screw assembly. Additionally, there is a snap ring at the base of the body that snaps into an internal groove in the bore of the cap, which assists in holding the cap in position on the construct. #### Performance Testing To validate the strength and safety of the system, testing was conducted according to methods defined in ASTM F 1798, "Standard Guide for Evaluating the Static and Fatigue Properties of Interconnection Mechanisms and Subassemblies Used in Spinal Arthrodesis Implants", and ASTM F 1717, "Standard Test Methods for Spinal Implant Constructs in a Vertebrectomy Model". The types of testing performed on the polyaxial screw assemblies and/or hook assemblies are listed below. #### Testing per ASTM F1798-08 The following types of testing were performed on the Marauder™ Cervical-Thoracic Spinal Fixation System per ASTM F1798-08: - 1. Static Flexion-Extension Strength - 2. Static Rod Gripping Capacity Strength - 3. Static A-P Pullout Strength #### Testing per ASTM F1717-12 The following types of testing were performed on the Marauder™ Cervical-Thoracic Spinal Fixation System per ASTM F1717-12: - 1. Static Compression Bending - 2. Static Torsional Bending - 3. Dynamic Compression Bending #### Conclusions The mechanical testing revealed that the Marauder™ Cervical-Thoracic Spinal Fixation System behaves as expected and is typical of competitive systems. In all instances, the Marauder™ Cervical-Thoracic Spinal Fixation System functioned as intended and the testing results observed were as expected. {3}------------------------------------------------ ## Substantial Equivalence Intelligent Implant Systems believes that the new Marauder™ Cervical-Thoracic Spinal Fixation System is substantially equivalent in design to: - S4® Spinal System (K050979) 0 - MESA® Mini Spinal Fixation System (K081107) o - Synthes Inc.
