An internal fixation device refers to a medical implant used in orthopedic surgeries to stabilize and facilitate healing of bones. When a bone is fractured or broken, the internal fixation device is surgically inserted into the affected area to hold the bone fragments in their proper position. The device consists of specialized components, such as screws, plates, rods, wires, or nails, that are made from biocompatible materials like titanium, stainless steel, or bioabsorbable polymers.
The primary purpose of an internal fixation device is to provide stability and promote the healing process of fractures or bone deformities. It helps to align the broken bone segments, preventing further movement or displacement. Furthermore, by immobilizing the bone fragments, it allows the surrounding tissue, including blood vessels, nerves, and muscles, to heal properly.
Internal fixation devices are commonly used in surgeries involving broken bones, such as fractures in the wrists, ankles, hips, or spine. They are also utilized in orthopedic procedures like joint reconstruction, corrective osteotomy, or fusion. The specific type of internal fixation device chosen depends on various factors, including the location and severity of the fracture or deformity, the age and overall health of the patient, and the surgeon's preference.
Overall, internal fixation devices play a crucial role in orthopedic surgery by providing mechanical strength and stability, aiding in the proper alignment of fractured bones, and ultimately facilitating the healing process.
