Wrist Joints External Fixator - Type A

The basic goal of fracture fixation is to stabilize the fractured bone, to enable fast healing of the injured bone, and to return early mobility and full function of the injured extremity.

External fixation is a technique used to help heal severely broken bones. This type of orthopedic treatment involves securing the fracture with a specialized device called a fixator, which is external to the body. Using special bone screws (commonly called pins) that pass through the skin and muscle, the fixator is connected to the damaged bone to keep it in proper alignment as it heals.

What is an external fixator used for?

An external fixation device may be used to keep fractured bones stabilized and in alignment. The device can be adjusted externally to ensure the bones remain in an optimal position during the healing process. This device is commonly used in children and when the skin over the fracture has been damaged.

What are the types of external fixator?

There are three basic types of external fixators: standard uniplanar fixator, ring fixator, and hybrid fixator.

The numerous devices used for internal fixation are roughly divided into a few major categories: wires, pins and screws, plates, and intramedullary nails or rods.

Staples and clamps are also used occasionally for osteotomy or fracture fixation. Autogenous bone grafts, allografts, and bone graft substitutes are frequently used for the treatment of bone defects of various causes. For infected fractures as well as for treatment of bone infections, antibiotic beads are frequently used.

Wrist Joints External Fixator: An Overview

The wrist is an essential joint that connects the forearm to the hand and provides support and flexibility to perform various activities. Unfortunately, injuries to the wrist are relatively common and can be caused by various factors such as falls, sports injuries, and car accidents. In severe cases, these injuries may require surgical intervention, and the wrist joint external fixator is a popular treatment option for severe wrist fractures. In this article, we will discuss the wrist joint external fixator in detail, including its definition, types, indications, and complications.

Introduction

The wrist joint external fixator is a medical device used to stabilize broken bones in the wrist. The device consists of metal pins or screws that are attached to the bones on either side of the fracture and connected with a metal frame outside the skin. This frame keeps the bones in place and allows them to heal correctly.

Types of External Fixators

There are various types of external fixators used to treat wrist fractures. Some common types include:

Uniplanar External Fixators

Uniplanar external fixators are the simplest type of fixator and consist of a single plane of support. These fixators are used in simple fractures and provide limited stability.

Circular External Fixators

Circular external fixators consist of two or more rings that are connected by wires or rods. These fixators are used in complex fractures and provide superior stability.

Hybrid External Fixators

Hybrid external fixators are a combination of uniplanar and circular fixators. These fixators are used in complex fractures where a combination of stability and flexibility is needed.

Indications for External Fixator Use

External fixators are primarily used to treat severe wrist fractures that cannot be treated with casts or braces. Some common indications for external fixator use include:

Open Fractures

Open fractures occur when a broken bone penetrates the skin, increasing the risk of infection. External fixators can be used to stabilize the fracture and reduce the risk of infection.

Comminuted Fractures

Comminuted fractures occur when a bone is broken into several pieces. External fixators can be used to stabilize the bone and promote proper healing.

Fractures with Soft Tissue Damage

Fractures that involve damage to the soft tissues surrounding the bone can be challenging to treat. External fixators can be used to stabilize the bone while allowing the soft tissues to heal.

Complications of External Fixator Use

Like any medical device, external fixators can cause complications. Some common complications include:

Infection

External fixators can increase the risk of infection, especially if the device is not properly maintained.

Pin Site Inflammation

The pins or screws used in external fixators can irritate the skin and cause inflammation.

Loss of Range of Motion

External fixators can limit the range of motion in the affected wrist, which can be challenging to regain after the device is removed.

Conclusion

The wrist joint external fixator is an effective treatment option for severe wrist fractures. It provides stability to broken bones, allowing them to heal correctly. However, like any medical device, external fixators can cause complications. Patients must work closely with their healthcare providers to ensure that the device is properly maintained and any complications are promptly addressed.
