The ENDOSKELETON® TA Interbody Fusion Device is indicated for use in skeletally mature patients with Degenerative Disc Disease (DDD) at one or two contiguous levels from L2-S1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. Patients should have received 6 months of non-operative treatment prior to treatment with the devices. The device is intended to be used with supplemental fixation that has been cleared by the FDA for use in the lumbar spine. These DDD patients may also have up to Grade I spondylolisthesis or retrolisthesis at the involved level(s). ENDOSKELETON® TA is indicated to be used with autograft bone or allograft bone comprised of cancellous and/ or corticocancellous bone.

The ENDOSKELETON® TAS Interbody Fusion device is indicated for use in skeletally mature patients with Degenerative Disc Disease (DDD) at one or two contiguous levels from L2-S1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. These DDD patients may also have up to Grade I spondylolisthesis or retrolisthesis at the involved level(s). Patients should have received 6 months of non-operative treatment prior to treatment with the devices. The device is a standalone system that is intended to be used with the bone screws provided and requires no additional supplementary fixation. The Device is indicated to be used with autograft bone or allograft bone comprised of cancellous and/ or corticocancellous bone.

The ENDOSKELETON® TC Interbody Fusion Device is indicated for use for anterior cervical interbody fusion in skeletally mature patients with degenerative disc disease (DDD) of the cervical spine at one disc level from C-3 to C-7. DDD is defined as discogenic pain with degeneration of the disc confirmed by history and radiographic studies. Patients should have received 6 weeks of non-operative treatment prior to treatment with the device. The ENDOSKELETON® TC Interbody Fusion Device is indicated to be used with supplemental fixation that has been cleared by the FDA for use in the cervical spine and autograft bone or allograft bone comprised of cancellous and/ or corticocancellous bone.

The Endoskeleton® TCS Interbody Fusion Device System is an anterior cervical intervertebral body fusion device indicated for use in skeletally mature patients with degenerative disc disease (DDD) (defined as pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies) at one disc level from C2 to T1. Patients should have received 6 weeks of non-operative treatment prior to treatment with the device. The device is indicated to be used with autograft bone or allograft bone comprised of cancellous and/ or corticocancellous bone. The device is a stand-alone system when used with Endoskeleton® TCS integrated screws and when used without the integrated screws it requires additional supplemental fixation cleared for the cervical spine.

The ENDOSKELETON® TL Interbody Fusion Device is indicated for use in spinal fusion procedures in skeletally mature patients with Degenerative Disc Disease (DDD) at one or two contiguous levels from L2-S1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. Patients should have received 6 months of non-operative treatment prior to treatment with the devices. This device is intended for use with supplemental fixation systems cleared for use in the lumbar spine. These DDD patients may also have up to Grade I spondylolisthesis or retrolisthesis at the involved level(s). Patients with previous non-fusion spinal surgery at the involved level(s) may be treated with the device. It is indicated to be used with autograft bone or allograft bone comprised of cancellous and/ or corticocancellous bone.
