As a pedicle screw system Aladyn Rigid Spine Plate is indicated for the treatment of severe spondylolisthesis (Grades 3 and 4) of the L5-S1 vertebra in skeletally mature patients receiving fusion by autogenous bone graft having implants attached to the lumbar and sacral spinc (L3 to sacrum) with removal of the implants after the attainment of a solid fusion. ## Device Story Aladyn Rigid Spine Plate is a posterior pedicle screw system for spinal immobilization/stabilization. System comprises rigid plates, hemispherical pedicle screws, and polyaxial nuts. Screws are inserted into vertebrae; plate is placed over screws and secured with nuts. Used in thoracic, lumbar, and sacral spine procedures. Modification of ISOLOCK and ISOBAR systems; eliminates use of washers. Implantation performed by surgeons in clinical/OR settings. Provides rigid fixation to support fusion; implants may be removed after solid fusion attainment. ## Clinical Evidence Bench testing only. Mechanical testing performed per ASTM F1717. Results demonstrated performance comparable to predicate ISOLOCK and ISOBAR Pedicle Screw Systems. ## Technological Characteristics Pedicle screw spinal system consisting of rigid plates, hemispherical screws (6.2mm diameter, 38-50mm lengths), and polyaxial nuts. Materials and design are modifications of predicate systems. Mechanical testing conducted per ASTM F1717. No software or electronic components. ## Regulatory Identification (1) Rigid pedicle screw systems are comprised of multiple components, made from a variety of materials that allow the surgeon to build an implant system to fit the patient's anatomical and physiological requirements. Such a spinal implant assembly consists of a combination of screws, longitudinal members (e.g., plates, rods including dual diameter rods, plate/rod combinations), transverse or cross connectors, and interconnection mechanisms (e.g., rod-to-rod connectors, offset connectors).(2) Semi-rigid systems are defined as systems that contain one or more of the following features (including but not limited to): Non-uniform longitudinal elements, or features that allow more motion or flexibility compared to rigid systems. ## Special Controls *Classification.* (1) Class II (special controls), when intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra; degenerative spondylolisthesis with objective evidence of neurologic impairment; fracture; dislocation; scoliosis; kyphosis; spinal tumor; and failed previous fusion (pseudarthrosis). These pedicle screw spinal systems must comply with the following special controls:(i) Compliance with material standards; (ii) Compliance with mechanical testing standards; (iii) Compliance with biocompatibility standards; and (iv) Labeling that contains these two statements in addition to other appropriate labeling information: “Warning: The safety and effectiveness of pedicle screw spinal systems have been established only for spinal conditions with significant mechanical instability or deformity requiring fusion with instrumentation. These conditions are significant mechanical instability or deformity of the thoracic, lumbar, and sacral spine secondary to severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra, degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudarthrosis). The safety and effectiveness of these devices for any other conditions are unknown.” “Precaution: The implantation of pedicle screw spinal systems should be performed only by experienced spinal surgeons with specific training in the use of this pedicle screw spinal system because this is a technically demanding procedure presenting a risk of serious injury to the patient.” (2) Class II (special controls), when a rigid pedicle screw system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion in the treatment of degenerative disc disease and spondylolisthesis other than either severe spondylolisthesis (grades 3 and 4) at L5-S1 or degenerative spondylolisthesis with objective evidence of neurologic impairment. These pedicle screw systems must comply with the following special controls: (i) The design characteristics of the device, including engineering schematics, must ensure that the geometry and material composition are consistent with the intended use. (ii) Non-clinical performance testing must demonstrate the mechanical function and durability of the implant. (iii) Device components must be demonstrated to be biocompatible. (iv) Validation testing must demonstrate the cleanliness and sterility of, or the ability to clean and sterilize, the device components and device-specific instruments. (v) Labeling must include the following: (A) A clear description of the technological features of the device including identification of device materials and the principles of device operation; (B) Intended use and indications for use, including levels of fixation; (C) Identification of magnetic resonance (MR) compatibility status; (D) Cleaning and sterilization instructions for devices and instruments that are provided non-sterile to the end user; and (E) Detailed instructions of each surgical step, including device removal. (3) Class II (special controls), when a semi-rigid system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion for any indication. In addition to complying with the special controls in paragraphs (b)(2)(i) through (v) of this section, these pedicle screw systems must comply with the following special controls: (i) Demonstration that clinical performance characteristics of the device support the intended use of the product, including assessment of fusion compared to a clinically acceptable fusion rate. (ii) Semi-rigid systems marketed prior to the effective date of this reclassification must submit an amendment to their previously cleared premarket notification (510(k)) demonstrating compliance with the special controls in paragraphs (b)(2)(i) through (v) and paragraph (b)(3)(i) of this section. ## Predicate Devices - ISOLOCK Pedicle Screw System ([K990721](/device/K990721.md)) - ISOBAR Pedicle Screw System ([K990118](/device/K990118.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Webb 1001 Oakwood Blvd Round Rock, TX 78681 512-388-0199 Common name Posterior pedicle screw system ### Classification name Spondylolisthesis spinal fixation device system Pedicle screw spinal system ### Equivalent Device The Aladyn Rigid Spine Plate is a modification to the ISOLOCK (K990721) and ISOBAR (K990118) Pedicle Screw Systems. ### Device Description The Aladyn Rigid Spine Plates, pedicle screws and a polyaxial nut. It is a modification to the plates and nuts of the ISOLOCK Pedicle Screw System (K990721) and uses the same hemispherical screws of the ISOBAR system (K990118). Pedicle screws are inserted into the vertebrae. An Aladyn plate is placed over the screws. The rigid plates are available in six multi-hole lengths. The construct is then scurely fixed with nuts. The implantation steps of the Aladyn are the SOLOCK Plate system. The only difference is that there are no washers used with the Aladyn plate. The hemispherical screws come in two diameters (6.2mm and in lengths ranging from 38mm to 50mm. There is also a polyaxial nut available. #### Intended Use The Aladyn Rigid Spine Plate is a pedicle screw system intended to provide immobilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: degenerative spondylolisthesis with objective evidence of neurological impairment, fracture, dislocation, scoliosis, spinal tumor, and failed previous fusion (pseudarthrosis). As a pedicle screw system Aladyn Rigid Spine Plate is indicated for the treatment of severe spondylolisthesis (Grades 3 and 4) of the LS-S1 vertebra in skeletally mature patients receiving fusion by autogenous bone graft having implants attached to the lumbar and sacral spine (L3 to sacrum) with removal of the attainment of a solid fusion. #### Summary Nonclinical Tests Testing was performed per ASTM F1717. Results were comparable with other devices on the ISOLOCK and ISOBAR Pedicle Screw Systems. {1}------------------------------------------------ Image /page/1/Picture/1 description: The image shows the seal of the Department of Health & Human Services - USA.
