Post-surgery Muscle Preservation and Pain Reduction Through Blood Flow Restriction Training in Orthopedic Spinal Surgery

This project investigates the effects of the Blood-Flow-Restriction (BFR) training method on postoperative muscle atrophy and pain after spinal surgery. Two groups are formed for this purpose. The intervention group receives a everyday BFR training during the postoperative stay at an individually measured occlusion pressure of 60-80%. The control group performs sham-BFR training at a fixed occlusion pressure of 20mmHg. The examinations are carried out before and several times after the operation (longest follow-up: 6 months). Among other things, muscle mass, muscle strength, pain perception and quality of life are assessed using questionnaires.

Digital Health Psychosocial Intervention for Adolescent Spine Surgery Preparation and Recovery

This is a randomized controlled trial to test effectiveness of the SurgeryPal intervention vs. education control to improve acute and chronic pain and health outcomes in youth undergoing major musculoskeletal surgery. Youth will be randomized on an individual level using a factorial design to SurgeryPal or Education during 2 phases of intervention: 1) pre-operative phase (4 week duration delivered over the 4 weeks leading up to surgery), and 2) post-operative phase (4 week duration following surgery). Thus there will be 4 treatment arms. Participants will undergo 4 assessments, independent of their treatment assignment: T1: Baseline (pre-randomization); T2: acute post-surgery outcomes (daily assessment of acute outcomes beginning day 1 through day 14 after hospital discharge from surgery); T3: Post-surgery follow-up (assessment of outcomes at 3-months post-surgery); T4: Final post-surgery follow-up (assessment of outcomes at 6-months post-surgery).

Prospective Study of ProteiOS in Lumbar Interbody Fusion (TLIF)

This is a prospective, multicenter, randomized, controlled study evaluating Influx™ ProteiOS®, an allograft-derived growth factor product, in transforaminal lumbar interbody fusion (TLIF). Participants undergoing 1- to 2-level TLIF (L2-S1) are randomized 2:1 to receive ProteiOS or a control graft (local bone with optional cancellous chip augmentation, no ProteiOS). The primary objective is to determine whether the 12-month interbody fusion rate (assessed by CT using the Brantigan-Steffee-Fraser classification) with ProteiOS is non-inferior to control, using a 5-percentage-point non-inferiority margin. Patient-reported outcomes (ODI, VAS, EQ-5D-5L), safety, and healthcare utilization are also assessed. A separate exploratory cohort at one study site will evaluate the same outcomes in participants undergoing anterior lumbar interbody fusion (ALIF) with or without ProteiOS, without formal hypothesis testing.

PREventing Pain After Surgery

The present study aims to adapt and modify a brief presurgical Acceptance and Commitment Therapy (ACT) intervention aimed at preventing the transition to Chronic Post-Surgical Pain (CPSP) and reducing long-term opioid use. Investigators will then assess the acceptability, feasibility, and preliminary efficacy of the finalized intervention to prevent the transition to CPSP and reduce post-surgical opioid use six months following lumbar spine surgery. Finally, investigators will identify psychosocial and psychophysical phenotypes associated with response to this intervention.

Effects of Orthosis & Exercise on Spondylolisthesis

In the treatment of spondylolisthesis, conservative methods are initially preferred unless severe neurological symptoms are present; surgical treatment is only performed in refractory cases lasting at least 3-6 months. Conservative treatment consists of orthotic use, activity restriction, pain control, physiotherapy and exercise. Orthotics may promote healing by restricting movement; however, there are not enough studies on this subject. Exercise is the intervention with the highest level of evidence in chronic low back pain. The efficacy of stabilisation exercises in providing positive and long-lasting effects on pain and functional disability in patients with spondylolisthesis has been demonstrated. However, studies evaluating the effect of exercise on spinal stability and radiological findings are limited. Therefore, this study aims to compare the effects of stabilization and conventional exercises with orthosis on radiographic findings, pain, physical function and quality of life.

Lumbar Fusion With Porous Versus Non-Porous Cages

The objective of this single site, randomized controlled trial is to assess and compare radiographic and clinical outcomes in patients who are to undergo lumbar interbody fusion procedures (TLIF), supplemented with pedicle screw instrumentation, using one of the following interventions: 1. Porous titanium cages 2. Non-porous titanium-coated poly-ether-ether-ketone (PEEK) cages.

Clinical Outcome and Fusion Rate of 3D Printed Interbody Fusion Cages and Titanium Coated PEEK Cages

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

Intercorporal Bone Graft Measurement Study

Instrumented lumbar fusion surgery is often accompanied by interbody fusion using an autologous bone graft that is supposed to expand and remodel to achieve a rigid and lasting bony construction between two vertebrae. However, there is a dearth of knowledge regarding the process of biological remodelling of intercorporal bone grafts. Also, a valid and reliable assessment of fusion status remains challenging because there is no objective tool available to quantify the bone remodelling process. CT-based Hounsfield Units correlate with Bone Mineral Density and can be used as a proxy to establish trajectories over time to assess changes in bone mineral density from the bone graft.

Advanced SPinal Innovations With Robotics and Enabling Technology Registry

Creation of a pediatric robotic spine surgery registry will allow for data collection and analysis on the coupled use of robotics and navigation, as well as patient-specific rods in pediatric spine deformity surgery across participating study institutions. Eventually, an educational and informative framework for this technology will be established.

This is a prospective, multi-center, observational Post-Market Clinical Follow-Up (PMCF) study designed to collect additional safety and clinical performance data on CE-marked Titania® spinal instrumentation and fusion systems, and Bonegraft® bone filling materials (synthetic bone grafts and bone cements). The study aims to evaluate short-term (12-month) safety and effectiveness, identify previously unknown side effects, monitor defined complications, and assess risks based on real-world evidence in patients undergoing spinal surgery. All investigated products are used within their intended purpose under routine clinical practice.

Decompression vs. Fusion for Stable Degenerative Spondylolisthesis

The purpose of this study is to assess the feasibility of a full-scale multicenter randomized, controlled trial comparing the effectiveness of two surgical treatments for a condition associated with lumbar spinal stenosis called degenerative lumbar spondylolisthesis. Both treatments are currently used, but individual surgeons use different selection criteria for each treatment and use the procedures at different rates. The two procedures are decompression with fusion (the most common surgical procedure for spondylolisthesis) and midline-sparing decompression alone (which is also a standard treatment, but is not as widely used for treating spondylolisthesis). The investigators plan to collect the evidence on the following: 1. The feasibility of the trial protocol, and 2. Preliminary data on the effectiveness of each treatment.

Perioperative ACT for Preventing CPSP

The present study aims to adapt and modify a brief perioperative Acceptance and Commitment Therapy (ACT) intervention aimed at preventing the transition to Chronic Post-Surgical Pain (CPSP) and reducing long-term opioid use. Investigators will assess the acceptability, feasibility, and preliminary efficacy of the intervention via a non-randomized, non-controlled pilot trial.

Ultrasound-Guided Erector Spinae Plane Block for Postoperative Pain Control in Lumbar Spondylolisthesis Surgery

This clinical trial aims to evaluate the effectiveness of ultrasound-guided erector spinae plane (ESP) block as an adjunct to general anesthesia for managing postoperative pain in patients undergoing lumbar spondylolisthesis surgery. The study will compare two groups: one receiving general anesthesia with ESP block (intervention group) and the other receiving general anesthesia alone (control group). The primary objective is to assess postoperative pain relief, opioid consumption, and hemodynamic stability. Secondary outcomes include adverse events and recovery quality. This trial will provide valuable insights into the efficacy of ESP block in improving recovery outcomes and reducing opioid use in spine surgery patients.
