Circumferential Vertebral Reconstruction of Osteoporotic Compression Fractures Using a Novel Bipedicular Peek Implant

Vertebral compression fractures affect an estimated 1.4 million patients in the world annually and incidence rates rise exponentially with age, especially in women. Outcomes following non-interventional management of these injuries are generally poor, largely as a consequence of opioid requirements, prolonged immobilization, and bedrest. As a result, interventional techniques such as balloon kyphoplasty and vertebroplasty with or without implantable devices are currently regarded as the standard of care for select patients with acute painful osteoporotic compression fractures. These procedures relieve fracture pain by stabilizing the fracture site using cement. Alternative interventional techniques include percutaneous vertebral augmentation, which combine cement injection with implantable devices, such as the SpineJack® and KIVA® devices. The RECONSTRUCT study will build on the outcomes of the SAKOS and KAST clinical trails that evaluated the SpineJack® and KIVA® devices, respectively. The Vertebral Implant PEEK (VIP) implant (V-STRUT© manufactured by Hyprevention) has undergone both clinical and pre-clinical testing. Static and dynamic bending of the implant has been evaluated to demonstrate that the product is capable of supporting in-situ loading, and increase fracture load and energy to fracture. A total of 30 eligible subjects with a diagnosis of osteoporotic fractures of the thoracolumbar spine, as confirmed by MRI scan, and who are treated with the Vertebral Implant PEEK (VIP) device will be asked to join the study. No placebo or control will be utilized during this study. RECONSTRUCT has been designed with the intention of achieving two goals: 1) to inform the design of larger controlled clinical trials in the future and 2) to assess the safety of the study device within the patient sample.
