Interne Fixation
An internal fixator refers to the implant (medicine) used in internal fixation of bones during orthopedic surgery. The concept of internal fixation dates to the mid 1800's.[1] An internal fixator may be made of stainless steel or titanium.
Types of internal fixators include bone screws and metal plates, pins, rods,[2] Kirschner wires and intramedullary devices such as the Kuntscher nail and interlocking nail.
Open Reduction Internal Fixation (ORIF) is a medical procedure. Open reduction refers to open surgery to set bones, as is necessary for some fractures. Internal fixation refers to fixation of screws and/or plates to enable or facilitate healing. Rigid fixation prevents micromotion across lines of fracture to enable healing and prevent infection, which happens when implants such as plates (e.g. Dynamic Compression Plate) are used. Open Reduction Internal Fixation techniques are often used in cases involving serious fractures such as comminuted or displaced fractures.
Risks and complications can include bacterial colonization of the bone, infection, stiffness and loss of range of motion, non-union, malunion, damage to the muscles, nerve damage and palsy, arthritis, tendonitis, chronic pain associated with plates, screws, and pins, compartment syndrome, deformity, audible popping and snapping, and possible future surgeries to remove the hardware.
