Minimally Invasive Fracture Fixation Technique

Abstract

Traumatic bone fracture injuries are among the most frequent orthopedic injuries treated worldwide and most often require surgical intervention to restore anatomical alignment and mobile function. Current conventional methods of treatment such as open reduction and internal fixation (ORIF) are typically accomplished by using plates, screws, or intramedullary rods to stabilize fractured segments of bone. However, these techniques typically require large surgical incisions resulting in extensive disruption of surrounding soft tissues, as well as extended recovery times for patients. Recently, there has been development of minimally invasive orthopedic procedures designed to decrease surgical trauma while still providing adequate mechanical support of bone fragments. Furthermore, the development of new biomaterials has led to the introduction of bioactive bone adhesives and calcium phosphate-based cements that improve the stabilization of fractures and support bone healing. The objective of this study is to propose a new concept for minimal invasive fracture fixation by integrating an expandable titanium wire stabilization system, injectable bio-adhesive bone bonding, and artificial intelligence (AI)-assisted imaging guidance using a C-arm fluoroscopy platform. The proposed device will consist of a micro instrumented titanium wire having an expandable, multi-arm tip configured to anchor itself to the internal anatomy to provide mechanical fixation to fracture fragments. Furthermore, the device will have a hollow internal channel allowing the biocompatible adhesive to be delivered directly into the fracture interface to further strengthen fixation. Additionally, artificial intelligence technology integrated into the imaging system allows for real-time assessment of fracture alignment and also provides visual support to surgeons during the surgical procedure. The combination of these technologies aims to reduce surgical trauma, limit blood loss, minimize operative times, and speed up recovery while ensuring that the fracture is functionally stable.
