What Is an Internal Fixation?

Internal fixation is an operation that uses metal screws, steel plates, intramedullary needles, steel wires, or bone plates to fix and fix broken bones directly inside or outside the broken bone. It is called internal fixation. This type of surgery is mostly used for fracture reduction and osteotomy to maintain the reduction of the folded end.

The main advantage of internal fixation is that it can better maintain the fracture

However, there should be sufficient understanding of the shortcomings of internal fixation. No matter what kind of metal internal fixation is, it is always a foreign body to the human body. It is common in clinical practice that osteoporosis or loosening of internal fixation occurs under and around the internal fixation. Once an infection occurs, metal foreign bodies can severely impede wound and fracture healing. At the same time, placement of internal fixation requires extensive stripping of soft tissue and

1. After reduction of the fracture, it is difficult to maintain the reduction of the fracture end by external fixation or traction, and internal fixation should be performed: If there is a strong muscle contraction at one end of the fracture (such as

In addition to the preoperative preparation for fracture reduction and reduction, the following preparations are required.

1. The metal quality of the internal fixation should be non-electrolytic, stainless, suitable in hardness and suitable in specifications. It is not advisable to apply products of two different metals at the same time, to avoid electrolysis, which causes bone resorption and loosening of internal fixation, which affects healing. The surface of the internal fixation should be smooth. It should not be used if it is damaged or restored after bending.

2. The nature, shape, location of the fracture and the condition of the patient should be fully studied before determining the type of internal fixation. And should fully estimate what may happen during the operation, and prepare to use other varieties of internal fixation. Before the operation, the x-ray film should be contrasted, and the internal fixation of appropriate thickness, length, width and thickness should be selected. It is best to prepare an internal fixation that is larger and smaller than the selected internal fixation for use in surgery.

3. Intra-articular fractures and femoral neck fractures should be prepared for x-rays for internal fixation in order to observe the reduction and internal fixation in time to guide the operation and ensure the success of the operation.

4. For cases with poor blood flow, healing or non-healing of old fracture deformities, bone grafting or periosteal grafting with blood vessels should be performed at the same time as incision reduction and internal fixation. ready.
