Intended Use

The CAPSTONE® Spinal System is indicated for interbody fusion with autogenous bone graft in patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1. These DDD patients may also have up to Grade 1 spondylolisthesis or retrolisthesis at the involved levels. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have had six months of non-operative treatment. These implants may be implanted via an open or a minimally invasive posterior approach. Alternatively, these implants may also be implanted via an anterior and/or transforaminal approach. These implants are to be used with autogenous bone graft. These devices are intended to be used with supplemental fixation instrumentation, which has been cleared by the FDA for use in the lumbar spine.

Device Description

The CAPSTONE® Spinal System consists of PEEK cages, titanium alloy cages and titanium cages of various widths and heights, which can be inserted between two lumbar or lumbosacral vertebral bodies to give support and correction during lumbar interbody fusion surgeries. The hollow geometry of the implants allows them to be packed with autogenous bone graft.

AI/ML Overview

This document is a 510(k) summary for the CAPSTONE® Spinal System, which is a premarket notification for a medical device. This type of document focuses on demonstrating substantial equivalence to existing legally marketed predicate devices, rather than presenting new clinical study data with acceptance criteria and performance metrics in the way a PMA (Pre-Market Approval) or a clinical trial report would.

Therefore, the input document does not contain the information requested regarding acceptance criteria, device performance tables, sample sizes for test/training sets, expert qualifications, adjudication methods, MRMC studies, standalone performance, or detailed ground truth methodologies typically found in clinical evaluation reports for novel devices or software.

The document states:

  • "Documentation, including mechanical test result, was provided which demonstrated that the subject CAPSTONE® Spinal System devices are substantially equivalent to the predicate CAPSTONE® Spinal System devices (K073291 SE 04/24/08, K082342 SE 09/15/08) as well as the VERTE-STACK® Spinal System devices (K062073 SE .08/14/06)."

This clearly indicates a predicate comparison approach, not a de novo clinical study with specific acceptance criteria as requested. The "acceptance criteria" here is substantial equivalence to the predicate devices based on mechanical testing and material properties, not clinical performance metrics against a defined standard.

In summary, the provided document does not contain the information needed to fill out the requested table and answer the detailed questions about clinical study design and performance metrics.

§ 888.3080 Intervertebral body fusion device.

(a)
Identification. An intervertebral body fusion device is an implanted single or multiple component spinal device made from a variety of materials, including titanium and polymers. The device is inserted into the intervertebral body space of the cervical or lumbosacral spine, and is intended for intervertebral body fusion.(b)
Classification. (1) Class II (special controls) for intervertebral body fusion devices that contain bone grafting material. The special control is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intervertebral Body Fusion Device.” See § 888.1(e) for the availability of this guidance document.(2) Class III (premarket approval) for intervertebral body fusion devices that include any therapeutic biologic (e.g., bone morphogenic protein). Intervertebral body fusion devices that contain any therapeutic biologic require premarket approval.
(c)
Date premarket approval application (PMA) or notice of product development protocol (PDP) is required. Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.
