Investigation of ossification capability and clinical outcome after fusion surgery of a vertebral segment in the lumbar region, a prospective, randomized, and blinded study
Résumé de l'étude
In spinal diseases that lead to back and/or leg pain, a possible treatment is the fusion of the affected segments of the spine. This can be done through surgery via the abdominal wall from the front (a technique called Anterior Lumbar Interbody Fusion or ALIF technique) or from the side (a technique called eXtreme lateral Lumbar Interbody Fusion or XLIF technique). The fusion is achieved through ossification between the vertebral bodies. To enhance bone formation, we use, as a standard therapy, a bone-forming protein (protein, manufacturer name InductOS). When using this protein, side effects may occur after the operation, e.g., temporarily prolonged leg pain. As an alternative to InductOS, we use a bone graft from a bone donation with bone structure and bone-forming cells (manufacturer name ViviGen®). In this study, we investigate whether the bone graft ViviGen® can achieve equally good stable ossification as the bone-forming protein InductOS.

Intervention étudiée
The division into two study groups is planned and will occur equally in a 1:1 ratio. One group will receive InductOS, the other group will receive ViviGen® during surgery.

Maladie en cours d'investigation
Eligible participants are all individuals aged between 18 and 70 years who suffer from back or leg pain or sciatica, and in whom explanatory changes in the spinal segment (segment = two adjacent vertebral bodies) L5/S1 or L4/L5 are diagnosed. Such a change can be the following: vertebral slippage (spondylolisthesis), disc degeneration, facet joint osteoarthritis (segment degeneration = wear) and/or narrowing of the spinal canal/nerve root (spinal/foraminal stenosis).
(BASEC)
- The patient has an indication for performing a monosegmental ALIF procedure at the L5/S1 segment or a monosegmental XLIF procedure at L4/5 (both ALIF and XLIF procedures with or without additional pedicular stabilization), e.g., for the treatment of conditions such as spondylosis, spondylolisthesis, and degenerative disc disease with back and/or leg pain - The patient is 18 to 70 years old - The patient has understood and signed the patient information and consent form - The patient is willing and able to complete the planned follow-up examinations/questionnaires as described in the patient information - (BASEC)
Critères d'exclusion
- The patient is under 18 years old or over 70 years old - The patient has a tumor / spinal trauma / known bone disease / Parkinson's disease and similar CNS disorders / diseases or injuries of the peripheral nerves - Other than the procedures or segments mentioned in the inclusion criteria - Additional planned spinal surgeries after the index operation - The patient is currently a smoker - The patient is pregnant or breastfeeding - Insufficient language skills in German - The patient is unable to give consent - Patient refuses to participate in the study, unsigned study consent - The patient is participating in another interventional study within 30 days prior to and during the present study (BASEC)
