Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Does a new "topping-off" device lead to a better clinical outcome compared to standard fusion? Does this device prevent the development of adjacent instability? Does radiological adjacent instability correlate with clinical outcome?

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Primary efficacy endpoint:

The baseline and follow-up values after 6 weeks after the operation as well as 6 and 12 months after baseline of the SF-36 (Short-Form-36)-Measured Outcome regarding the Physical Component Summary (PCS).

Key secondary endpoint(s):

1. Mental Component Summary (MCS) and individual dimensions and subscales of the SF-36
2. Individual dimensions of the Oswestry Disability Index (ODI)
3. Time until radiological adjacent instability and comparison to the clinical outcome
4. Capacity of work at the time of surgery and after surgery, time until return to work

Assessment of safety:

1. Treatment complication in control and intervention groups (SAE-management)
2. A rating committee will provide consistency of the procedure and the assessment of data (e.g. by intraoperative photos, surgery reports, x-rays) to minimize bias

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Arm1: "topping off" system

The intervention group will receive a "topping off" system (PLIF -posterior intervertebral fusion- connected with a flexible pedicle screw system above the fusion).

Group Type OTHER

Topping off system

Intervention Type DEVICE

The intervention group will receive a "topping off" system (PLIF -posterior intervertebral fusion- connected with a flexible pedicle screw system above the fusion).

Arm 2: monosegmental PLIF

The control group receives a monosegmental PLIF. This is the current standard therapy for many pathologies in the lumbar spine (e.g. Spondylolisthesis)

Group Type OTHER

monosegmental PLIF

Intervention Type DEVICE

The control group receives a monosegmental PLIF. This is the current standard therapy for many pathologies in the lumbar spine (e.g. Spondylolisthesis)
