Product Description
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.
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.
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.

The wrist joint is an essential component of the human body as it facilitates a wide range of movement and enables us to carry out various tasks. However, due to injury or disease, the wrist joint may become unstable, leading to pain and impaired function. In such cases, a wrist joint external fixator may be necessary to stabilize and support the joint during the healing process. In this article, we will discuss the wrist joint external fixator, its components, indications, surgical technique, post-operative care, and possible complications.
A wrist joint external fixator is a device that is used to stabilize the wrist joint during the healing process following an injury or surgery. It is commonly used in cases of complex fractures, dislocations, or ligament injuries of the wrist joint. The external fixator is placed outside the skin and is attached to the bones using pins or wires, which are inserted through the skin into the bone.
Before discussing the wrist joint external fixator, it is important to understand the anatomy of the wrist joint. The wrist joint is a complex joint that is made up of eight small bones called carpals, which are arranged in two rows. The carpals are connected to the radius and ulna bones of the forearm, forming the wrist joint.
The wrist joint allows for a wide range of movement, including flexion, extension, abduction, adduction, and rotation. It is stabilized by ligaments, tendons, and muscles that surround the joint.
A wrist joint external fixator is a device that is used to stabilize the wrist joint following an injury or surgery. The device consists of two main components: the frame and the pins or wires. The frame is attached to the bones using pins or wires, which are inserted through the skin into the bone. The frame is then adjusted to hold the bones in place and allow for the proper healing of the wrist joint.
The components of a wrist joint external fixator include the frame and the pins or wires. The frame is typically made of metal and is designed to fit around the wrist joint. It is attached to the bones using pins or wires, which are inserted through the skin into the bone. The pins or wires are connected to the frame using clamps or screws, which allow for adjustments to be made to the frame as necessary.
A wrist joint external fixator may be indicated for a variety of injuries or conditions, including:
Complex fractures of the wrist joint
Dislocations of the wrist joint
Ligament injuries of the wrist joint
Non-union of wrist joint fractures
Malunion of wrist joint fractures
Infections of the wrist joint
The surgical technique for wrist joint external fixation involves the following steps:
Administration of anesthesia: The patient is given either general or regional anesthesia.
Placement of the pins or wires: The pins or wires are inserted through the skin into the bone using a drill or special tool. The number and placement of the pins or wires will depend on the nature and location of the injury.
Attachment of the frame: The frame is attached to the pins or wires using clamps or screws, and adjustments are made to the frame as necessary to ensure proper alignment of the bones.
Post-operative imaging: X-rays or other imaging studies may be performed to confirm proper placement of the fixator.
After surgery, the patient will require close monitoring and follow-up care to ensure proper healing of the wrist joint. The following post-operative care measures are typically recommended:
Pain management: The patient will be prescribed pain medication to manage discomfort during the healing process.
Pin or wire care: The pins or wires will need to be cleaned and dressed regularly to prevent infection.
Physical therapy: The patient may require physical therapy to regain strength and mobility in the wrist joint.
Follow-up appointments: The patient will need to attend regular follow-up appointments with their surgeon to monitor the healing process and make any necessary adjustments to the fixator.
Like any surgical procedure, wrist joint external fixation carries some risks and possible complications, including:
Infection at the pin or wire site
Damage to nerves or blood vessels
Malalignment of the bones
Delayed healing or non-union of the bones
Pain or discomfort
Limited range of motion
A wrist joint external fixator is an effective device for stabilizing and supporting the wrist joint during the healing process following an injury or surgery. It is a relatively simple procedure that can be performed under general or regional anesthesia. However, like any surgical procedure, there are risks and possible complications that should be discussed with your surgeon before undergoing the procedure.
How long does a wrist joint external fixator stay in place?
The length of time that a wrist joint external fixator stays in place will depend on the nature and severity of the injury. In some cases, the fixator may only be necessary for a few weeks, while in other cases it may need to be in place for several months.
Is a wrist joint external fixator painful?
The placement of the pins or wires can cause some discomfort or pain, but this can be managed with pain medication. Once the fixator is in place, it should not cause any significant pain or discomfort.
Can I still use my hand with a wrist joint external fixator?
The fixator may limit the range of motion in the wrist joint, but most patients are able to use their hand and fingers for basic tasks during the healing process.
Will I need physical therapy after having a wrist joint external fixator?
Most patients will require some form of physical therapy to regain strength and mobility in the wrist joint following the removal of the fixator.
How long does it take to recover from wrist joint external fixation?
The length of time it takes to recover from wrist joint external fixation will depend on the nature and severity of the injury, as well as the individual's overall health and healing ability. In general, most patients will require several weeks or months to fully recover.
