The Evolution of External Fixators: Types and Innovations
There are few surgical procedures more ubiquitous in the orthopedic surgeon’s repertoire than the technique of applying an external fixator to a fractured extremity. There are many types of external devices and each type targets unique requirements and issues. Let’s dive in and explore the different kinds of external fixators and delve into the modular fixation system.
Understanding External Fixators Types
External fixators are devices used to keep fractured bones in place. These are placed externally and help in stabilizing the affected area and keeping the broken bones in alignment to promote recovery. External fixators are broadly categorized into three main types: conventional pin fixators, ring fixators and hybrid fixators, each with different applications:
Standard Pin Fixators: These are the simplest type of external fixators where pins are directly-screwed into the bone. They are most commonly applied to simpler fractures where adequate rigidity can be afforded with comparatively little implantation of hardware.
Ring Fixators: As the name suggests, ring fixators are placed around the limb, arm, or foot, encircling them fully or partially. The rings are fixed on the bones using wires, struts, and special pins so that they could easily be adjusted or corrected as required.
Hybrid Fixators: Hybrid fixing is formed by combining standard pin and ring fixators. They are mostly applied in multiple types of fractures that need reinforcement or stabilization.
The Modular Fixator: The Surgery Revolution in Orthopedics
The modular fixator stands as one of the significant developments in external fixation technology. In contrast with the traditional fixators, the modular fixators are developed for fast application and easy adjustability. They include one sub-assembly partial frame that connects to one of the main fracture fragments with pins and rods. These frames are joined by rod-to-rod construction, designed to assert and enable accurate control and minimization of the fracture
Another advantage of the modular fixators is that they are applied without intraoperative x-rays. This makes the procedure faster and (more) minimally invasive thereby minimizing adverse effects. Furthermore, modular fixators can be adjusted after the application making it easier for the doctor in treatment and correct alignment and stability of limbs.
Advantages and Uses of External Fixators
These fixators are applied in various scenarios ranging from simple fractures to complex deformities. It is especially useful in those particular cases when internal fixation cannot be used, for example with open fractures or in cases with a high probability of infection. In limb lengthening and deformity corrections, external fixators are very useful and give a patient a ray of hope for better functionality and quality of life.
The Future Of Orthopedic Surgery
External fixators have revolutionized the field of orthopedics, giving a new way of handling complicated cases such as fractures and deformities. After the use of the modular fixators, the opportunities of the patients getting the best orthopedic treatment improved even more. External fixators are not only orthopedic accessories, but they also represent the genuine efforts of the medical community. These innovations and improvements give us all hope for a better future ahead especially for orthopedic surgeons.
