Construx Mini
PEEK Spacer System

​​​​The Construx™ Mini PEEK Spacer System is comprised of a variety of implants manufactured from PEEK in two footprint sizes, small and large, and in various heights, in one-millimeter increments. The superior and inferior surfaces of the implant have a pattern of ripples to provide increased stability and help prevent anterior/posterior movement of the device.​

Unique Design Characteristics

  • Radiolucent implant with titanium markers for intraoperative visibility
  • Anti-migration ribs for secure placement
  • Large center opening for packing bone grafting material
  • Multiple implant options enable various surgical solutions
  • Straightforward instrumentation for easy implantation​


​When used as a cervical intervertebral body fusion device, the Construx Mini PEEK Spacer System is indicated for spinal fusion procedures at one or two contiguous levels within the cervical spine (C2-T1), in skeletally mature patients with degenerative disc disease (DDD). DDD is defined as neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies.

The Construx Mini PEEK Spacer System is intended for use with autograft and/or allograft comprised of cancellous and/or corticocancellous bone graft; and supplemental fixation (i.e. anterior cervical plate such as the Orthofix ACP or Hallmark® System).

Patients must have undergone a regimen of at least six (6) weeks of non-operative treatment prior to being treated with the Construx Mini PEEK Spacer System in the cervical spine.

When used as a Partial Vertebral Body Replacement (VBR) System, the Construx Mini PEEK Spacer System is indicated for use in the thoracolumbar spine (T1-L5) for partial replacement (i.e., partial vertebrectomy) of a diseased vertebral body resected or excised for the treatment of tumors, to achieve anterior decompression of the spinal cord and neural tissues, and to restore the height of a collapsed vertebral body. The Construx Mini PEEK Spacer System is also indicated for treating fractures of the thoracic and lumbar spine.

The Construx Mini PEEK Spacer System is designed to restore the biomechanical integrity of the anterior, middle, and posterior spinal column even in the absence of fusion for a prolonged period of time. The Partial VBR device is intended to be used with autograft or allograft.

The Construx Mini PEEK Spacer System is intended for use with supplemental fixation. The supplemental fixation system that may be used with the Construx Mini PEEK Spacer System is the Orthofix Spinal Fixation System (SFS) or the Firebird® Spinal Fixation System.


The Construx Mini PEEK Spacer System, as with other orthopedic implants, is contraindicated for use in patients:

  • With active infections in which the use of an implant could preclude adequate and appropriate treatment of the infection.
  • With rapidly progressive joint disease or bone absorption syndromes such as Paget’s disease, osteopenia, osteoporosis, or osteomyelitis which may prevent adequate fixation.
  • With conditions that may place excessive stresses on bone and implants, such as severe obesity, pregnancy or degenerative diseases. The decision to use this system in such conditions must be made by the physician taking into account the risks versus the benefits to the patient.
  • With prior fusion at the level to be treated.
