Implantable cervical disk system
The PCM® Cervical Disc System from NuVasive is indicated for use in skeletally mature patients for reconstruction of a degenerated cervical disk at one level from C3-C4 to C6-C7 following single-level diskectomy for intractable radiculopathy, with or without neck pain, or myelopathy due to a single-level abnormality localized to the disk space and manifested by herniated nucleus pulposus, spondylosis, and/or visible loss of disk height as compared to adjacent levels. The device is implanted using an anterior approach. Patients should have had at least 6 weeks of unsuccessful conservative treatment prior to implantation.

Available in three different footprint and height options, the PCM Cervical Disc System is composed of cobalt chrome endplates and a central polyethylene core. According to the manufacturer, the broad radius of the polyethylene core allows for unconstrained motion preservation and a broad radius of articulation for coupled motion.

Spinal fusion device
The iO-Tome™ instrument (A) from Baxano, Inc., uses the company’s iO-Flex platform to deliver a new MicroBlade Shaver® design configured to rapidly and precisely remove the facet joint in spinal fusion applications. The instrument reportedly creates a precise window at the treatment level that provides direct visualization of the neural structures and clear access to the disk for placement of the selected interbody implant.

Revision instruments designed for operating room efficiency
DePuy Orthopaedics’ new SIGMA High Performance (HP) Revision Instruments (B), designed for use with DePuy’s SIGMA Knee implants, reportedly reduce the average number of instrument cases and tibial preparation steps required during knee revision surgery. The system also incorporates visual cues and easy adjustments on the cutting blocks and a new simplified trialing system to enable surgeons to increase efficiency throughout the procedure.

The HP Revision Instruments work with DePuy’s SIGMA Rotating Platform Knee and Metaphyseal Sleeves. Revision knees utilizing rotating platform technology diffuse shear and torsional forces typically produced at the implant bone interface, according to DePuy. Metaphyseal Sleeves are stepped sleeves designed to compensate for substantial type 2 and 3 cavitary defects while bringing the implant into contact with strong, supportive bone. The sleeve is stepped to compressively load the bone and form a strong foundation for reliable implant stability, avoiding excessive bone resection and restoring the joint line.

Instruments for hip arthroscopy
DePuy’s ENDURANCE Hip Solutions (C) is a new system of instruments and devices for hip arthroscopy procedures. The system includes stainless steel needles, nitinol guidewires, and clear cannulas available in 90 mm and 110 mm, suture anchors in either BIOCRYL® RAPIDE™ biocomposite material or PEEK for fixation, and devices for tissue ablation and fluid management.

System enables postimplant biologic placement
The InFill® System from Pinnacle Spine Group consists of the InFill® Interbody Fusion Device and InFill® Graft Delivery System that together enable precise placement of approved biologic material into an implanted device during direct lateral spinal fusion procedures. Filling the device with biologic material postimplantation rather than prior to implantation is believed to improve endplate engagement with the biologic material, states the manufacturer.

The InFill® System includes lateral interbody fusion devices manufactured from PEEK-Optima®, supplied in a sterile, single-use package. The implant is designed to provide a generous bone grafting area, with endplate contact surfaces that optimize the weight-bearing properties of the cage. The Graft Delivery System is designed to facilitate controlled and precise placement of biologic material into the implanted device. The system also features specialized instrumentation, including an innovative retractor system, extensive disk, and endplate preparation options.

Hinged knee implant
Smith & Nephew’s LEGION HK Hinge Knee implant (D) is reportedly the first hinged knee to be designed using normal knee kinematics. The LEGION HK enables surgeons to seamlessly transition intraoperatively from a constrained revision implant to a hinged assembly, thus using a minimal number of instruments and the same reproducible surgical technique with which they are familiar, Smith & Nephew states. In addition, the implant is said to provide a more natural range of motion while maintaining an average of 96 percent condylar loading, thereby removing the stresses from the hinge link for lower wear on the hinge device.

Traceable pedicle screw system
SafeOrthopaedics states that its SteriSpine™ PS Pedicle Screw system is the world’s first single-use, sterile, and traceable system for fixation of the lumbar spine. All SteriSpine PS components meet Unique Device Identifier (UDI) regulatory requirements in the United States and Western Europe. This feature, according to the manufacturer, ensures comprehensive tracking capability and traceability of the implants and instruments used in each surgical procedure.

Low-profile screw with captured head technology
Smith & Nephew’s TRIGEN Low-Profile Screw features captured head technology—heads with internal threads that securely attach the screws to the screwdriver, potentially eliminating the risk of a screw being lost during surgery. The TRIGEN Low-Profile Screw is designed to enable surgeons to combine the patient-friendly aspects of a lower profile head with the efficiency and security of a captured screw.

Available in 2.5-mm increments, the new screws also feature a unique fluted design that helps surgeons “feel” when the screw is fully seated. The TRIGEN Low-Profile Screw is designed for use with the entire TRIGEN System, a portfolio of nailing options for long bones that addresses lower-extremity fractures. It is also compatible with the TRIGEN SURESHOT Distal Targeting System, a virtual, real-time imaging system that enables surgeons to distally lock screws without the use of fluoroscopy.
