Brief summary
Prospective, Randomized, Single-Blind Study for the Evaluation of the Clinical Outcome and the Fusion Rate of 3D Printed Interbody Fusion Cages and Titanium Coated PEEK Cages in Transforaminal Lumbar Interbody Fusion
Detailed description
This clinical study is a regulatory Post Market Clinical Follow-Up (PMCF) measure and is aiming to collect clinical data on the performance and safety of the TSPACE® 3D implants. It is designed as a prospective, randomized, single-blind, non-interventional study in order to gain clinical data within the routine clinical application of the investigational device. The study shall answer the question if there are detectable differences between the established titanium coated Polyether Ether Ketone (PEEK) cages of the manufacturer and the new 3D printed cages. Differences shall be observed in terms of clinical outcome, quality of life, patient satisfaction, radiological outcome and occurrence of Adverse Events / Serious Adverse Events.
Interventions
Interbody Fusion means the operative immobilization or ankylosis of two or more vertebrae by fusion of the vertebral bodies with a short bone graft or often with diskectomy or laminectomy. (From Blauvelt and Nelson, A Manual of Orthopaedic Terminology, 5th ed, p236; Dorland, 28th ed

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Clinical outcome measured with the Oswestry Disability Index | 1 year postoperatively | The Oswestry Disability Index is designed to measure back-specific disability. The questionnaire is self-administered and has 10 items concerning pain and activities of daily living including personal care, lifting, walking, sitting, standing, sleeping, sex life, social life and travelling. It is a self-administered questionnaire Each section is scored on a 0-5 scale, 5 is for maximum disability. The index is calculated by dividing the total score by the total possible score, which is multiplied by 100 and expressed as a percentage. The scores for all questions answered are summed, then multiplied by two to obtain the index (range 0 to 100). Zero is equated with no disability and 100 is the maximum disability possible. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical improvement: pain | preoperatively, at 3 months, 1 year, 2 years and 5 years postoperatively | Pain will be assessed by the patient using the Visual Analogue Scale (VAS) which state "0" at one end representing "no pain" and "100" at the opposite end representing "maximal/worst pain" |
| Development Quality of life (EQ-5D-5L) | preoperatively, at 3 months, 1 year, 2 years and 5 years postoperatively | EQ-5D-5L is a standardized 5-dimension 5-level measure of the health status and is developed by the EuroQol Group in order to have a simple and generic measure for clinical and economic assessment. In order to analyze the quality of life of the patients, the EQ-5D-5L is used. The score is self-completed by the patient and will therefore be used in German. |
| Radiological outcome: Fusion | 1 year postoperatively | Bone fusion: After interbody fusion surgery fusion of the treated segment is aspired. Thus, the implant design shall allow on-/ingrowth to/into the material. The fusion status can be determined from radiographs (static or dynamic). Bony fusion can be characterized quantitatively by the fusion rate. |
| Radiological outcome: Implant subsidence | 1 year postoperatively | Implant penetration into the vertebral body occurs frequently after spinal reconstruction. Interbody fusion cages may subside into the vertebral body and lead to kyphotic deformity |
| Radiological outcome: Implant migration | 1 year postoperatively | Interbody fusion cages might migrate forward into the retroperitoneum or backwards into the vertebral canal and can, thus, cause serious clinical consequences (e.g. compression of nerve roots or dura mater). |
| Rate of (Serious) adverse events | throughout the studies duration up to five years postoperatively | Occurrence of complications potentially associated with the implanted devices can never be fully excluded during spinal surgery. In order to monitor potential complication and to identify so far unknown complications adverse events (AE) and serious adverse events (SAE) deemed related to the investigational device are recorded. |
| Development of Clinical outcome measured with the Oswestry Disability Index | preoperatively, at 3 months, 1 year, 2 years and 5 years postoperatively. | The Oswestry Disability Index is designed to measure back-specific disability.
