Low back pain (LBP) is a devastating musculoskeletal ailment that impacts majority of the global population. Up to 95% of cases are considered nonspecific where the origin is unclear. Although there is a diagnosis with these cases, there lacks specificity that would help individuals with treatment and pain management. Imaging techniques such as magnetic resonance imaging (MRI) are primarily utilized in the diagnosis of LBP as it illuminates internal structures of the spine. One important structure clearly identified with MRI is the intervertebral disc (IVD) that is susceptible to injury and disease. Further, diagnostic imaging is performed lying down where …

Despite countless surgical advances over the last several decades refining surgical approaches, repair techniques, and tools to treat tendon and tendon-to-bone injuries, we are still left with repair solutions that rely on fairly crude underlying mechanical principles. Musculoskeletal soft tissues have evolved to transfer high loads by optimizing stress distribution profiles across the tissue at each length scale. However, instead of mimicking these natural load transfer mechanisms, conventional suture approaches are limited by high load transfer across only a small number of anchor points within tissue. This leads to stress concentrations at anchor points that often cause repair failure as …
