No
The 510(k) summary describes a mechanical spinal fixation system and does not mention any software, algorithms, or AI/ML capabilities. The performance testing described is mechanical in nature.
Yes
The device is intended to provide immobilization and stabilization of spinal segments as an adjunct to fusion for various spinal conditions, including fractures, instability, deformity, and degenerative diseases, which are therapeutic purposes.
No
The device is described as a system of fixation devices (screws, hooks, rods, connectors) used to immobilize and stabilize spinal segments, acting as an adjunct to fusion. It is a treatment device, not one designed to diagnose conditions.
No
The device description explicitly states it consists of physical fixation devices manufactured from Ti-6Al-4V, such as screws, hooks, rods, and connectors, which are attached to the spine. This indicates a hardware-based medical device, not a software-only one.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
- Device Description: The provided text describes a surgical implant system (screws, hooks, rods, connectors) used to stabilize the spine. It is a physical device implanted in the body, not used to test samples from the body.
- Intended Use: The intended use clearly states it's for "immobilization and stabilization of spinal segments as an adjunct to fusion." This is a surgical procedure, not a diagnostic test performed on a specimen.
Therefore, based on the provided information, the Spinal Elements Lotus Posterior Cervical/Thoracic Spinal System is a surgical implant device, not an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
The Spinal Elements Lotus Posterior Cervical/Thoracic Spinal System is intended to provide immobilization and stabilization of spinal segments as an adjunct to fusion for the following acute and chronic instabilities of the cervical spine (C1 to C7) and the thoracic spine from T1-T3; traumatic spinal fraumatic dislocations; instability or deformity; failed previous fusions (e.g., pseudarthrosis); tumors involving the cervical/thoracic spine; and degenerative disease, including intractable radior myelopathy, neck and/or arm pain of discogenic origin as confirmed by radiographic studies, and degenerative disease of the facets with instability. The Lotus Posterior Cervical/Thoracic Spinal System is also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the cervical spine in whom life expectancy is of insufficient duration to permit achievement of fusion.
In order to achieve additional levels of fixation, the Lotus Posterior Cervical/Thoracic Spinal System may be connected to the Mercury® Spinal System with the Lotus Posterior Cervical/Thoracic rod connectors. Transition rods with differing diameters may also be used to connect the Lotus Posterior Cervical/Thoracic Spinal System to the Mercury Spinal System. Refer to the Mercury Spinal System package insert for a list of the Mercury Spinal System indications for use.

Device Description
The Lotus Posterior Cervical/Thoracic Spinal System consists of a variety of fixation devices manufactured from Ti-6Al-4V that are attached to the spine. Screws may be placed from a posterior approach into the cervical and/or thoracic spine. Hooks may be placed on the posterior elements of the various vertebrae. Rods span the distance between the screws/hooks, and various other connectors may be used between rods or between rods and screws/hooks. The system achieves fixation by the mechanical joining of the rods, screws, hooks and connectors. A variety of constructs may be assembled to suit the individual pathology and anatomy of the patient.

§ 888.3075 Posterior cervical screw system.
(a)
Identification. Posterior cervical screw systems are comprised of multiple, interconnecting components, made from a variety of materials that allow an implant system to be built from the occiput to the upper thoracic spine to fit the patient's anatomical and physiological requirements, as determined by preoperative cross-sectional imaging. Such a spinal assembly consists of a combination of bone anchors via screws (i.e., occipital screws, cervical lateral mass screws, cervical pedicle screws, C2 pars screws, C2 translaminar screws, C2 transarticular screws), longitudinal members (e.g., plates, rods, including dual diameter rods, plate/rod combinations), transverse or cross connectors, interconnection mechanisms (e.g., rod-to-rod connectors, offset connectors), and closure mechanisms (e.g., set screws, nuts). Posterior cervical screw systems are rigidly fixed devices that do not contain dynamic features, including but not limited to: non-uniform longitudinal elements or features that allow more motion or flexibility compared to rigid systems.Posterior cervical screw systems are intended to provide immobilization and stabilization of spinal segments in patients as an adjunct to fusion for acute and chronic instabilities of the cervical spine and/or craniocervical junction and/or cervicothoracic junction such as: (1) Traumatic spinal fractures and/or traumatic dislocations; (2) deformities; (3) instabilities; (4) failed previous fusions (
e.g., pseudarthrosis); (5) tumors; (6) inflammatory disorders; (7) spinal degeneration, including neck and/or arm pain of discogenic origin as confirmed by imaging studies (radiographs, CT, MRI); (8) degeneration of the facets with instability; and (9) reconstruction following decompression to treat radiculopathy and/or myelopathy. These systems are also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the cervical spine in whom life expectancy is of insufficient duration to permit achievement of fusion.(b)
Classification. Class II (special controls). The special controls for posterior cervical screw systems are:(1) The design characteristics of the device, including engineering schematics, must ensure that the geometry and material composition are consistent with the intended use.
(2) Nonclinical performance testing must demonstrate the mechanical function and durability of the implant.
(3) Device components must be demonstrated to be biocompatible.
(4) Validation testing must demonstrate the cleanliness and sterility of, or the ability to clean and sterilize, the device components and device-specific instruments.
(5) Labeling must include the following:
(i) A clear description of the technological features of the device including identification of device materials and the principles of device operation;
(ii) Intended use and indications for use including levels of fixation;
(iii) Device specific warnings, precautions, and contraindications that include the following statements:
(A) “Precaution: Preoperative planning prior to implantation of posterior cervical screw systems should include review of cross-sectional imaging studies (
e.g., CT and/or MRI) to evaluate the patient's cervical anatomy including the transverse foramen, neurologic structures, and the course of the vertebral arteries. If any findings would compromise the placement of these screws, other surgical methods should be considered. In addition, use of intraoperative imaging should be considered to guide and/or verify device placement, as necessary.”(B) “Precaution: Use of posterior cervical pedicle screw fixation at the C3 through C6 spinal levels requires careful consideration and planning beyond that required for lateral mass screws placed at these spinal levels, given the proximity of the vertebral arteries and neurologic structures in relation to the cervical pedicles at these levels.”
(iv) Identification of magnetic resonance (MR) compatibility status;
(v) Cleaning and sterilization instructions for devices and instruments that are provided non-sterile to the end user, and;
(vi) Detailed instructions of each surgical step, including device removal.
