Osteosynthesis procedure

These 10 facts about space will blow your mind When a bone is fractured, the broken pieces must be set back in their proper place and held together in order to heal correctly. The process of setting broken bones is called reduction. Setting a fracture without surgery is called closed or external reduction. When surgery is required, the process is referred to as open or internal reduction.

Osteosynthesis procedure

Listen Osteosynthesis Osteosynthesis is defined as fixation of a bone. It is a surgical procedure to treat bone fractures in which bone fragments are joined with screws, plates, nails or wires.

Osteosynthesis procedure

The fractured bone is fixed with the aforementioned and can knit stably in the correct position. Osteosynthesis or internal bone fixation are not used to treat every type of bone fracture. Osteosynthesis is most suitable for open bone fractures with concomitant injury to the skin or soft tissue.

It is also the preferred form of treatment for bone fractures with multiple fragments, bone fractures on the leg and bone fractures in patients with osteoporosis. Different osteosynthesis methods such as screw osteosynthesis, plate osteosynthesis, intramedullary pin osteosynthesis, tension band osteosynthesis, Kirschner wire fixation, external fixation devices and dynamic hip screw are used.

The materials used nowadays consist primarily of titanium. What preparations are carried out before the procedure? The bone fracture must be precisely imaged in an x-ray or an MRI before the operation. Based on the examination results, the doctor decides which osteosynthesis method to use.

All the usual pre-operative assessments are required, such as a blood test, blood pressure measurement and an ECG. The patient must stop taking blood-thinning medication and have an empty stomach for the procedure.

How is the operation carried out? The location of the fracture and the type of break will have a bearing on which surgical procedure is used. Furthermore, the location of the fracture and the patient's general condition will also determine whether the surgery is carried out under general anaesthesia, spinal anaesthesia or local anaesthesia.

Screw osteosynthesis In the case of screw osteosynthesis, the bone fragments are fixed with screws. A hole is drilled in the broken piece in question to this end. A thread for the screw [tension screw] is drilled in the opposing fragment or a screw with a thread on the end of it is used directly [cancellous bone screw].

In both cases, the broken pieces are joined together by tightening the screws. Plate osteosynsthesis Plate osteosynthesis is a procedure in which the broken parts of the bone are fixed with a plate. The surgeon exposes the broken bone and screws a suitable plate over the fracture line.

This is fixed to all the fragments with screws in the bone. In the process, the broken parts are connected stably with one another. Intramedullary nail osteosynthesis Intramedullary pin osteosynthesis is a procedure in which the medullary cavity is opened in the broken bone.

The surgeon makes a channel in the medullary cavity into which he or she can drive a nail. This nail connects the bone fragments in the manner of an internal splint. The intramedullary nail is also stabilised with a crossways bolt so that it cannot displace itself.

The nail is correctly positioned with the help of x-ray imaging. Tension band osteosynthesis Tension band osteosynthesis is a complex procedure in which bone fragments are pressed together.

Fixation wires are attached to the fragments, and they are joined together with a tension band.Osteosynthesis is the reduction and internal fixation of a bone fracture with implantable devices that are usually made of metal.

It is a surgical procedure to treat bone fractures in which bone fragments are joined with screws, plates, nails or wires. ing that procedure, the same technique already described for distal humeral fractures is performed [6].

Conclusion Minimally invasive osteosynthesis is a simple. Osteosynthesis: A surgical procedure that stabilizes and joins the ends of fractured (broken) bones by mechanical devices such as metal plates, pins, rods, wires or screws. Osteosynthesis refers particularly to internal fixation of a fracture by such means, as opposed to external fixation of a.
