Surgalign has filed a patent for an implantable, modular spine stabilization system. The system allows for multi-level treatment of the spine, providing either rigid fixation or dynamic stabilization at different levels. It can be customized to fit a patient’s spine curvature and can be implanted using minimally invasive surgery. The system includes flexible couplers, rigid rods, and bone fasteners with specific threaded portions.

Implantable modular spine stabilization system with flexible couplers and rigid rods
A recently filed patent (Publication Number: US20230200857A1) describes an implantable, modular spine stabilization system. The system includes flexible couplers, rigid rods, and bone fasteners for stabilizing a spinal segment of a patient's spine.
The flexible couplers have a flexible main body and a bendable stem, while the rigid rods have an elongated shaft. The bone fasteners are used to attach the flexible couplers or rigid rods to the patient's spine. Each bone fastener has a head portion with a cavity for receiving an implantable device, and a shank portion with an elongated shaft extending to a distal tip. The shank portion has quad lead threads, with a first leading threaded portion adjacent to the distal tip, a second trailing threaded portion adjacent to the head portion, and an intermediate threaded portion between them.
The patent also mentions that the flexible couplers can be configured to attach to each other or to one of the rigid rods. The stem of the flexible couplers can be curved or straight, and it may have a threaded end. The flexible main body of the couplers has a threaded opening for attaching to the stem of another flexible coupler.
Similarly, the elongated shaft of the rigid rods can be curved or straight, and it may have a threaded end. The flexible main body of the couplers also has a threaded opening for attaching to the elongated shaft of one of the rigid rods.
The system allows for dynamic stabilization of the spinal segment using the flexible couplers and rigid stabilization using the rigid rods. The different sizes of the flexible couplers and rigid rods provide flexibility in adapting to the specific needs of the patient.
Overall, this patent describes an implantable, modular spine stabilization system that combines flexible couplers, rigid rods, and bone fasteners to provide stabilization and support to a patient's spinal segment. The system offers versatility in terms of attachment options, stem and shaft configurations, and size variations.
