DSS® Dynamic Stabilization System

DSS Stabilization System

Customized Stabilization for Specific Pathologies

The DSS Dynamic Stabilization System* is a complete systematic approach to lumbar stabilization. The System is made up of a “fusion” coupler and a “dynamic” coupler, also known as “connectors,” that are placed between the pedicle screws. The DSS dynamic coupler increases the segmental stiffness of the affected motion segment and restricts the range of motion in flexion, extension, lateral bending and rotation while preserving motion. By selecting the appropriate size DSS dynamic coupler, the posterior segmental height can be adjusted. The rigid coupler provides rigid segmental fixation thereby promoting fusion.

The modularity of the DSS Stabilization System allows the combination of DSS dynamic couplers with DSS fusion couplers at adjacent levels. Therefore, one segment may have functionally dynamic stabilization (non-fusion) while an adjacent segment has rigid segmental fixation (fusion).

Regulatory approvals vary by country. Therefore, we kindly ask you to contact the distributor in your region regarding availability of specific products, implants and / or instrumentation in your region. Please note that this presentation is not valid for Germany.

DSS Stabilization System

  • Pain Relief

    • Controlled dynamic stabilization of hypermobile segment(s)
    • Restoration of the natural center of rotation
    • Shock absorption; axial compression
    • Control of rotation and stress reduction on facet joints

    Hybrid Solutions

    • Modularity of system allows combination of fusion and dynamic stabilization
    • Adjacent levels are effectively protected

    Ease of Use

    • Cannulated screws support minimally invasive application
    • Paraspinal muscle-splitting technique minimizes iatrogenic trauma
    • Easy-to-use instrumentation
  • The DSS Stabilization System is not approved for non-fusion in the U.S.


    The DSS Stabilization System is indicated for skeletally mature patients with degenerative disc disease (DDD) at one to three levels from L1 to S1, including conditions such as grade 1 spondylolisthesis. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies.


    Do not use the DSS implant in cases of:

    • Any medical or surgical condition precluding the potential benefit of spinal surgery
    • Acute or chronic systemic, spin al or localized infections
    • Active systemic and metabolic diseases
    • Obesity
    • Pregnancy
    • Dependency on pharmaceutical drugs, drug abuse, or alcoholism
    • Lack of patient cooperation
    • Foreign body sensitivity to the implant material
    • Degenerative spondylolisthesis greater than grade 1 or isthmic spondylolisthesis
    • Degenerative scoliosis greater than 25 degrees
    • Significant osteopenia

    Safety Precautions

    • Only stabilize a segment with either dynamic couplers or fusion couplers. Do not use both a dynamic coupler and a fusion coupler at the same level
    • Prior to use, thoroughly read these instructions for use and become familiar with the surgical technique.
    • Keep the instructions for use accessible to all staff.
    • The operating surgeon must have a thorough command of both the hands-on and conceptual aspects of the established operating techniques. Proper surgical performance of the implantation is the responsibility of the operating surgeon.
    • The manufacturer is not responsible for any complications arising from incorrect diagnosis, choice of incorrect implant, incorrect operating techniques, the
      limitations of treatment methods or inadequate asepsis.
    • Under no circumstances may modular implant components from different suppliers be combined.
    • Each patient's record shall document the implant used (name, article number, lot number).
    • During the postoperative phase, in addition to mobility and muscle training, it is of particular importance that the physician keeps the patient well informed about post-surgical behavioral requirements.
    • Damage to the weight-bearing structures can give rise to loosening, dislocation and migration, as well as other complications. To ensure the earliest possible detection of such catalysts of implant dysfunction, the implant must be checked periodically post operative using appropriate techniques.
    • Never reuse an implant. Although the implant may appear undamaged, previous stresses may have created non-visible damage that could result in implant failure.
    • Never use implants if the packaging is damaged. An implant with damaged packaging might be damaged itself and thus may not be used.
    • Never use implants that are past their expiration date.
    • Do not resterilize implants.
