Indications for Use
The STALIF MIDLINE™ is indicated for use 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 I 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. Patients with previous non-fusion spinal surgery at the treated level may be treated. These implants may be implanted via a laparoscopic or an open anterior approach. The STALIF MIDLINE™ is a stand-alone system intended to be used with the bone screws provided and requires no additional supplementary fixation systems. The STALIF MIDLINE™ system must be used with bone grafting material (autograft only).
Device Story
STALIF MIDLINE™ is a radiolucent intervertebral body fusion device designed for spinal stabilization. It functions as a stand-alone system, utilizing provided unicortical cancellous bone screws to eliminate the need for supplemental fixation. The device is implanted by surgeons via laparoscopic or open anterior approaches to treat degenerative disc disease. It acts as a spacer to facilitate fusion when used with autogenous bone graft. The system is a modification of the predicate STALIF™ TT, featuring an updated anti-back out mechanism and expanded sizing options to accommodate varying patient anatomy. By providing immediate stability and promoting fusion, the device aims to alleviate discogenic back pain.
Clinical Evidence
Bench testing only. Mechanical performance was evaluated in accordance with ASTM F2077 (static/dynamic compression, torsion, and compression-shear) and ASTM F2267 (static subsidence). Results demonstrate the device is mechanically equivalent to the predicate.
Technological Characteristics
Radiolucent intervertebral body fusion device with unicortical cancellous bone screws. Stand-alone system requiring no supplemental fixation. Tested per ASTM F2077 and ASTM F2267. No software or electronic components.
Indications for Use
Indicated for skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels (L2-S1), including those with up to Grade I Spondylolisthesis or retrolisthesis. Requires six months of failed non-operative treatment. Suitable for patients with prior non-fusion spinal surgery at the treated level.
Regulatory Classification
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.
Special Controls
*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.
