![]() 1 In comminuted fractures, the locking screws bear the transmitted load until the fracture has consolidated. ![]() The efficacy of statically locked intramedullary nails inserted after reaming for the treatment of fractures of the femoral shaft has been well established. Recovery will typically last for several months. A common activity that may result in a comminuted fracture is cycling.Ĭompared to regular fractures, comminuted fractures will take longer to heal. Sports and Other Outdoor Activities: Fractures will typically occur if a person does numerous sports and other outdoor activities. A bone may break into numerous pieces due to various causes, which are the following: A pressure of about 160 pounds is necessary to cause this injury. Bigger bones, like the femur, are much stronger. To be specific, a minor bone will have this kind of damage if it receives a pressure of about 9–13 pounds. The comminuted fractures will only happen if a bone has received an extreme pressure. An Infection is a common complication associated to open fractures. An open one can lead to a complication since the internal tissues are exposed to the environment. Depending on its severity, it can either be an open or closed fracture. As mentioned, a comminuted fracture is an injury resulting to several pieces of broken bones. Repairing a comminuted fracture often requires open surgery to restructure the bone to normal anatomy. External fixation devices such as splints and casts are usually inadequate in treating this type of fracture. Since considerable force and energy is required to fragment bone, fractures of this degree occur after high-impact trauma such as in vehicular accidents. Analyses confirmed results, in terms of mechanical performances, comparable with the others traditional systems of prosthesis.Ī comminuted fracture is a break or splinter of the bone into more than two fragments. A complete numerical FE model of an implanted femur was analyzed, by considering a vertical load of 980 N. The operative technique for the introduction of this type of prosthesis for the decomposed fracture of long bones consists in the incision of the fracture site, introduction of the open shell prosthesis with reduction of the fracture and composition of the bone fragments, closure by means of fixing screws of the prosthesis shell, stitching open wound flaps. Two screws then hold the two valves together. The proposed prosthesis consists of two shell valves hinged to each other by a central pin and bearing slits along the surface in such a way as to guarantee the exchange of body fluids and at the same time ensure the structural stability of the bone. In this paper, an innovative design of prosthesis, conceived to heal the comminuted fractures of long bones has been investigated.
