Lumbar Spine Muscle Degeneration Inhibits Rehabilitation-Induced Muscle Recovery
Disc DegenerationLow Back PainLow back pain (LBP) is a complex condition that affects 65-85% of the population, and is the leading musculoskeletal condition contributing to disability in the United States. Disc herniation is the most common injury and 75% of individuals undergoing surgical and rehabilitative interventions for this condition experience suboptimal or poor outcomes. These patients demonstrate disability and deficits in functional capacity, including strength and endurance of the lumbar musculature. Muscle-specific changes in individuals with LBP include altered muscle volume, fatty infiltration and fibrosis, and fiber area and type. Importantly, these changes are insensitive to rehabilitation in patients with continued chronic or recurrent symptoms. While normal disuse-related atrophy in the presence of LBP is expected, more severe or chronic pathology, such as inflammation and fiber damage, may be inducing irreversible fiber degeneration and fatty/fibrotic tissue changes that impair muscle function and recovery. While the structural and adaptive capacities of healthy muscle are well understood, muscle recovery in the presence of pathology is less clear. To address this gap in knowledge, the purpose of this project is to compare structural, physiological, and adaptive responses of muscle in the presence of acute and chronic lumbar spine pathology. The central hypothesis is that chronic injury results in a state of muscle inflammation, atrophy, fibrosis, and muscle degeneration that is not responsive to exercise. The Investigators will identify which patients respond to exercise by examining muscle hypertrophic, fibrotic, inflammatory, and adipogenic gene expression profiles. Patients will be followed for six months post-operatively to measure muscle recovery and strength.
Long-Term Assessment of the Safety and Performance of the NuVasive Simplify Disc at Two Levels
Cervical Disc DiseaseDegenerative Disc DiseaseA prospective, multicenter post-market clinical follow-up study to evaluate the 10-year long-term safety and effectiveness of the Simplify Disc at two levels in subjects who were enrolled in the IDE study (NCT03123549) and/or post approval study (NCT04980378).
Cervical Interbody Implant Study
Degenerative Disc DiseaseCervical Spinal InstabilityThe primary objective of this study is to evaluate the safety and performance of cervical spine surgery using interbody implants as measured by reported complications, radiographic outcomes, and patient-reported outcomes (PROs).
Natural Matrix Protein™ (NMP™) in Interbody Lumbar Fusion
Degenerative Disc DiseaseThe objective of this study is to evaluate the performance of Induce Biologics NMP™ when used to promote interbody fusion for degenerative disease of the lumbar spine.
Outcome Analysis for Minimally Invasive Spine Surgery and Navigation
Degenerative Disc DiseaseProspective/Retrospective data analysis, chart reviews and clinical outcomes of minimally invasive spine surgery
Advanced Materials Science in XLIF Study
Degenerative Disc DiseaseSpondylolisthesisThis study is being conducted to evaluate the clinical and radiographic outcomes of three different interbody implant types when used with cancellous allograft chips with BMA or cellular allograft in patients undergoing XLIF surgery. The study will evaluate success by comparing the rate of fusion, complications profile, and any relationships between clinical outcomes (pain and function) and radiographic outcomes (fusion rate) between the three implant groups.
Posterior Cervical Fixation Study
Degenerative Disc DiseaseCraniocervical Injuries7 moreThe objective of this study is to evaluate the safety and performance of occipito-cervico-thoracic spine surgery using posterior fixation as measured by reported complications, radiographic outcomes, and patients reported outcomes (PROs).This study is being undertaken to identify possible residual risks and to clarify mid-to long-term clinical performance that may affect the benefit/risk ratio of posterior fixation systems.
Modulus in XLIF Study
