Product Description

Locking Plates System

External fixators can achieve "damage control" in fractures with severe soft tissue injuries, and also serve as definitive treatment for many fractures. Bone infection is a primary indication for the use of external fixators. Additionally, they can be employed for deformity correction and bone transport.

Orthofix Type External Fixator System

This series includes 3.5mm/4.5mm Eight-plates, Sliding Locking Plates, and Hip Plates, designed for pediatric bone growth. They provide stable epiphyseal guidance and fracture fixation, accommodating children of different ages.

Ilizarov Type External Fixator System

The 1.5S/2.0S/2.4S/2.7S series includes T-shaped, Y-shaped, L-shaped, Condylar, and Reconstruction Plates, ideal for small bone fractures in hands and feet, offering precise locking and low-profile designs.

Hoffmann Type External Fixator System

This category includes clavicle, scapula, and distal radius/ulnar plates with anatomical shapes, allowing multi-angle screw fixation for optimal joint stability.

Synthes AO Type External Fixation System

Designed for complex lower limb fractures, this system includes proximal/distal tibial plates, femoral plates, and calcaneal plates, ensuring strong fixation and biomechanical compatibility.

Common External Fixator System

This series features pelvic plates, rib reconstruction plates, and sternum plates for severe trauma and thorax stabilization.

DFN Distal Femur Intramedullary Nail (Spiral Blade Screw Type)

Product Advantage

Minimally Invasive, Preserves Blood Supply

External fixation typically involves only small incisions or percutaneous pin insertion, causing minimal damage to the soft tissues, periosteum, and blood supply around the fracture site, which promotes bone healing.

Broad Indications

It is particularly suitable for severe open fractures, infected fractures, or fractures with significant soft tissue damage, as these conditions are not ideal for placing large internal implants within the wound.

Facilitates Wound Monitoring and Management

Since the frame is external, it provides excellent access for subsequent wound care, debridement, skin grafting, or flap surgery without compromising fracture stability.

Adjustability

After surgery, the physician can make fine adjustments to the position, alignment, and length of the fracture fragments by manipulating the connecting rods and joints of the external frame to achieve a more ideal reduction.

Ankle Joint External Fixator: A Comprehensive Guide

Ankle fractures are common injuries that can result in significant disability and pain. While non-displaced or minimally displaced fractures can be treated conservatively, displaced fractures often require surgical intervention. Ankle joint external fixators are one of the options available for treating displaced ankle fractures. This article aims to provide a comprehensive guide to ankle joint external fixators, including their indications, surgical technique, outcomes, and potential complications.

What is an Ankle Joint External Fixator?

An ankle joint external fixator is an external device used to stabilize ankle fractures. The device consists of metal pins or wires that are inserted through the skin and into the bone, which are then connected to a frame that surrounds the ankle joint. The frame is secured to the bone with clamps, and the pins or wires are tensioned to provide stability to the fracture site.

Indications for Ankle Joint External Fixators

Ankle joint external fixators are indicated for a wide range of ankle fractures, including intra-articular fractures, open fractures, and those with significant soft tissue injuries. They are particularly useful in cases where traditional methods of fixation, such as plates and screws or intramedullary nails, are not feasible. Ankle joint external fixators are also useful in cases where early weight-bearing is desirable, as they provide stable fixation while allowing for early mobilization.

Surgical Technique

The placement of an ankle joint external fixator is a complex procedure that requires careful planning and execution. The surgery is typically performed under general anesthesia, and the patient is placed in a supine or lateral position. The pins or wires are inserted percutaneously or through small incisions, and the frame is attached to them. The wires are tensioned to provide stability and compression to the fracture site. After the placement of the frame, the ankle joint's alignment is checked and adjusted as necessary. Postoperatively, the patient is encouraged to start early mobilization and weight-bearing as tolerated.

Complications

Complications associated with ankle joint external fixators include pin tract infections, wire or pin breakage, joint stiffness, and neurovascular injuries. The incidence of complications can be reduced by proper pin placement, appropriate tensioning of wires, and regular pin site care. The incidence of major complications is low, and most can be managed conservatively or with simple surgical procedures.

Outcomes

Ankle joint external fixators have shown excellent outcomes in the treatment of displaced ankle fractures. They allow for early weight-bearing, leading to faster healing and better functional outcomes. Studies have shown that ankle joint external fixators have a higher union rate, lower infection rate, and lower reoperation rate compared to traditional methods of fixation.

Conclusion

Ankle joint external fixators are a valuable tool in the treatment of displaced ankle fractures. They provide stable fixation, precise control of alignment, and allow for early mobilization and weight-bearing. While the placement of an ankle joint external fixator is a complex procedure, the outcomes are excellent, with lower complication rates compared to traditional methods of fixation.
