Effectiveness of Orthopedic Implants
Effectiveness of Orthopedic Implants would be a crucial and important topic in development of such medical devices. After creation of the design conception by the orthopedic surgeons, the implants are manufacturing using various types of conventional and state-of-art processes and materials. Immediate, short-term, and long-term interaction of the bone with orthopedic implants would would show the effectiveness of an implant for treatment of its intended use or indication. a
Three- or Four-Part Proximal Humerus Fracture
Four parts fracture pattern is formed as the results of boundary conditions that are constrained by the muscles-tendons attachment in humeral head, greater tuberosity, lesser tuberosity, and humeral shaft. Due to these constraints, the fracture line is mostly occurred at the surgical neck section, anatomical neck section, and the middle section between the tuberosities. a
Fixation of multi-fragmentary fracture in 3 or 4 fragments, at the proximal humerus zone, have been found very challenging to be managed [1–13,13–29]. In order to treat the fixation of the complex multi-fragmentary proximal humerus fractures, various open reduction and internal fixation (ORIF) implants or devices were clinically utilized and the outcomes were reported in the literature [1,2,11–13,13–19,3,20–29,4–10]. a
